N-biphenylmethylindole modulators of PPARG

BACKGROUND

The peroxisome proliferator active receptors (PPARs), members of the nuclear hormone receptor superfamily, comprise several subtypes such as PPAR.alpha., PPAR.beta., and PPAR.gamma.. The PPAR.gamma. subtype, also referred to as PPARG, is the target of the glitazone pharmaceutical agents used for treatment of type II diabetes. PPARG is also known as NR1C3 (the gene ID) and there exist PPARG1 and PPARG2, the two major isoforms of PPARG. The glitazones, such as pioglitazone and rosiglitazone, act as PPARG receptor agonists. However, other classes of pharmaceutical agents, such as Telmisartan, have been reported to act as partial agonists, binding in a different mode to PPARG and having different cofactor requirements. See Y. Lamotte, et al., Bioorg. Med. Chem. Lett. (2010), 20, 1399-1404.

SUMMARY

The present invention is directed to compounds that are non-activating (non-agonist) PPARG modulators, and to the use of these compounds in modulating the activity of PPARG, such as in treatment of conditions wherein non-activating modulation of PPARG is medically indicated, such as diabetes, insulin resistance, impaired glucose tolerance, pre-diabetes, hyperglycemia, hyperinsulinemia, obesity, or inflammation. Compounds of the invention can block kinase-mediated, such as cdk5-mediated, phosphorylation of PPARG, but are not agonists of the receptor itself. By avoiding agonism of the receptor, the compounds may exhibit no or reduced side effects associated with administration of full and partial agonists of PPARG, such as significant weight gain, edema, impairment of bone growth or formation, or cardiac hypertrophy, or any combination thereof. Compounds of the invention can bind both PPARG1 and PPARG2, the two major isoforms of PPARG.

In various embodiments, the invention provides a non-agonist PPARG modulatory compound of formula (I), or a pharmaceutically acceptable salt thereof:

DETAILED DESCRIPTION

Overview

PPARG (also known as PPAR.gamma.) is a member of the nuclear receptor family of transcription factors. This protein is a dominant regulator of adipose cell differentiation and development. It is also the functioning receptor for the thiazolidinedione (TZD) class of anti-diabetic drugs, such as rosiglitazone and pioglitazone. These drugs were developed before their molecular modes of action were known, but later compounds were developed specifically as anti-diabetic drugs with high affinity and full agonism toward PPARG transcriptional activity. It has therefore been assumed that the therapeutic actions of these drugs result from their functional agonism on this receptor. From a clinical perspective, rosiglitazone (Avandia.RTM.) and pioglitazone (Actos.RTM.) are both highly effective oral medications for type 2 diabetes and are well tolerated by the majority of patients. Unfortunately, a substantial number of patients experience side effects from these drugs, including fluid retention, congestive heart failure and loss of bone mineral density. Since many diabetics have pre-existing cardiovascular disease or are at risk for heart problems, the fluid retention is particularly troubling. While some of the non-TZD full agonists also have good anti-diabetic activity, they also cause many of the same side effects, including fluid retention.

The therapeutic role of classical agonism of PPARG was made somewhat confusing by the development of several compounds that have less than full agonist properties (partial agonists) but retain substantial insulin-sensitizing and anti-diabetic actions in experimental models. Furthermore, we have recently shown that many anti-diabetic PPARG ligands of the TZD and other chemical classes have a second, distinct biochemical function: blocking the obesity-linked phosphorylation of PPARG by cyclin-dependent kinase 5 (cdk5) at serine 273. This is a direct action of the ligands and requires binding to the PPARG ligand binding domain (LBD) causing a conformational change that interferes with the ability of cdk5 to phosphorylate serine 273. Other kinase enzymes than ckd-5 can also mediate the phosphorylation of PPARG, and compounds of the invention can block the phosphorylation of PPARG without acting as PPARG agonists.

Rosiglitazone and MRL24 (a selective PPARG partial agonist) both modulate serine 273 phosphorylation at therapeutic doses in mice. Furthermore, a small clinical trial of newly diagnosed type 2 diabetics showed a remarkably close association in individual patients between the clinical effects of rosiglitazone and the blocking of this phosphorylation in PPARG. Thus, the contribution made by classical agonism to the therapeutic effects of these drugs or to their side effects can be deleterious.

The inventors herein have developed entirely new classes of compounds than can be effective anti-diabetic drugs that are optimized for the inhibition of cdk5-mediated phosphorylation of PPARG while being devoid of classical agonism. In this application we describe the development of a class of synthetic small molecules that bind tightly to PPARG and effectively inhibit phosphorylation at serine 273, yet are completely devoid of classical agonism. These compounds have unique binding modes in the ligand binding pocket of PPARG. An example possessing this type of bioactivity has been found to exhibits potent and dose-dependent anti-diabetic effects in obese mice. Importantly, this compound does not cause the fluid retention, weight gain, or impact mineralization in MC3T3 cells as is seen with rosiglitazone and other drugs that are full or partial agonists of PPARG.

Development of Novel Non-Agonistic PPARG Ligands

In order to develop a suitable ligand, we optimized compounds for (i) high binding affinity for PPARG, (ii) blocking the cdk5-mediated PPARG phosphorylation and (iii) lacking classical agonism. Classical agonism is defined here, as is standard in the nuclear receptor field, as an increased level of transcription through a tandem PPAR response element luciferase reporter (PPRE::Luc). Using a lanthascreen competitive binding assay, compound SR1664 (FIG. 1a) had an IC.sub.50 of 80 nM, indicating potent PPARG binding in vitro. As shown in FIG. 1b, when compared to rosiglitazone or MRL24 (a partial agonist), in a classical transcriptional activity assay on a tandem PPRE::Luc reporter, SR1664 had essentially no transcriptional agonism at any concentration. Rosiglitazone and SR1664 both effectively blocked the cdk5-mediated phosphorylation of PPARG in vitro (FIG. 1c) with half-maximal effects between 20 and 200 nM. In contrast, they had no effect on the phosphorylation of a well characterized cdk5 substrate, the Rb protein (FIG. 1d). This suggested that these compounds do not disrupt the basic protein kinase function of cdk5. In addition, SR1664 was also effective at blocking cdk5-mediated phosphorylation of PPARG in differentiated fat cells (FIG. 1e), indicating that SR1664 is effective in penetrating into living cells.

Other compounds of formula (I) were also synthesized and tested. Another compound of the invention, SR1824 (FIG. 1a), was further characterized to demonstrate its ability to block cdk5-dependent phosphorylation of PPARG (FIG. 1b-e). These data demonstrate the existence of molecular entities that bind PPARG at nanomolar concentrations, potently block cdk5-dependent phosphorylation of PPARG in cells, while demonstrating little to no classical agonism.

SR1664, a specifically claimed compound of the invention, was thus identified as non-agonist inhibitor of cdk5-mediated PPARG phosphorylation. SR1664 also was found to possess adequate pharmacokinetic properties to move forward to biological and therapeutic assays. Adipogenesis was the first known biological function of PPARG (Tontonoz et al., 1994) and agonist ligands for PPARG have been shown to potently stimulate the differentiation of pre-adipose cell lines; this response has been widely used as a sensitive cellular test for PPARG agonism (Kliewer et al., 1995; Lehmann et al., 1995).

As shown in FIG. 2a, rosiglitazone potently stimulated fat cell differentiation, as evidenced by Oil Red O staining of the cellular lipid. In contrast, SR1664 did not stimulate increased lipid accumulation or changes in morphology characteristic of differentiating fat cells. The stimulation of fat cell gene expression was also apparent with rosiglitazone, as illustrated by an increased expression of aP2, C/EBP.alpha. and Glut4 (FIG. 2b). In contrast, SR1664 induced little or no change in the expression of these genes linked to adipogenesis.

Another widely reported side effect of both rosiglitazone and pioglitazone is that they decrease bone formation and bone mineral density leading to an increase in fracture risk (Grey et al., 2007; Kahn et al., 2008). TZDs have also been shown to decrease bone mineralization in cultured osteoblasts (Lecka-Czemik, 1999). As shown in FIG. 2c, rosiglitazone treatment reduced the mineralization (calcification) of mouse osteoblastic cells (MC3T3-E1 cells), as measured by Alizarin red S staining. Moreover, the expression of genes involved in the differentiation of these cells was impaired (alkaline phosphatase, RANKL, type I collagen). Importantly, the treatment with SR1664 did not affect the extent of calcification or the expression of this osteoblast gene set in MC3T3-E1 cells.

Anti-Diabetic Activity of a Non-Agonist that Blocks cdk5-Dependent Phosphorylation

Wild-type mice fed a calorie dense diet high in sugar and fat become obese and insulin-resistant, with activation of cdk5 in their adipose tissues (Choi et al., 2010). FIG. 3a demonstrates that SR1664, injected twice daily for 5 days, caused a dose-dependent decrease in the cdk5-mediated phosphorylation of PPARG at serine 273 in adipose tissue. Moreover, SR1664 treatment also caused a trend toward lowered (and normalized) glucose levels, and a significant reduction in the fasting insulin levels. Insulin resistance, as computed by HOMA-IR, showed a clear and dose-dependent improvement with SR1664 (FIG. 3b). These changes occurred without significant differences in body weight compared to vehicle treated mice.

The most accurate method for measuring changes in insulin sensitivity is the hyperinsulinemic-euglycemic clamp (DeFronzo et al., 1979). In this method, animals are exposed to an elevated concentration of insulin while the amount of glucose infused is adjusted in real time to maintain fixed, or clamped glycemia. As shown in FIG. 3c, the glucose infusion rate (GIR) needed to maintain euglycemia in the mice treated with SR1664 was significantly greater than in animals treated with the vehicle alone. This indicates that SR1664 works as an insulin sensitizer. Suppression of endogenous hepatic glucose production (EGP), an important component of insulin action, was increased by SR1664. While whole body glucose utilization was not increased, glucose uptake in the adipose tissue, a marker of insulin sensitivity, was significantly enhanced. Similarly, the reduction in plasma FFA under basal and clamped conditions suggest improvements in adipose tissue insulin sensitivity. Thus, these data indicate that SR1664 improves insulin sensitivity.

Using cells expressing the S273A mutant of PPARG, we previously defined a gene set in cultured adipose cells that was most sensitive to this phosphorylation (Choi et al, 2010). Inhibition of cdk5 with a chemical inhibitor or administration of a partial agonist caused significant changes in 9/17 (53%) members of this gene set (Choi et al, 2010). Treatment of mice with SR1664 caused changes in the expression of 11/17 (65%) of these genes, all in the direction predicted for the inhibition of the PPARG S273 phosphorylation (FIG. 3d). Adiponectin and adipsin, genes long recognized for being reduced in obesity (Hu et al, 1996; Yamauchi et al, 2001; Flier et al, 1987), are both induced by SR1664. We also defined a separate set of genes reflective of a full agonist (rosiglitazone) on cultured fat cells. SR1664 caused changes in expression of 6/19 genes in this "agonist" gene set; importantly, three of these changes were in the same direction as expected for an agonist, but three were changed in the opposite direction (FIG. 3e). Taken together, these data show that SR1664 has an insulin-sensitizing effect with preferential regulation of the gene set sensitive to the phosphorylation of PPARG by cdk5.

A more severe model of obesity is the leptin-deficient ob/ob mouse. These animals are very obese and insulin-resistant, with substantial compensatory hyperinsulinemia. We performed preliminary pharmacokinetic and pharmacodynamic experiments comparing rosiglitazone and SR1664, to determine dosing regimens. Comparable drug exposures were achieved with treatments of 40 mg/kg for SR1664 and 8 mg/kg for rosiglitazone, both injected twice daily. Functional analyses were performed at days 5 and 11 after the start of treatments. As shown in FIG. 4a, both drugs caused a similar reduction in PPARG phosphorylation at S273. After five days of treatment, there were no overt differences in fasting body weight or glucose levels (vehicle 110.+-.13 mg/dL, rosiglitazone 88.+-.13 mg/dL, and SR1664 90.+-.12 mg/dL; FIG. 4b). Mice receiving only the vehicle control remained hyperinsulinemic, but both rosiglitazone and SR1664 substantially reduced these insulin levels (FIG. 4b). Glucose tolerance tests were markedly improved with both rosiglitazone and SR1664, and the improvements in the areas under these glucose excursion curves were statistically indistinguishable, without changing body weight (FIG. 4c).

Longer treatments with these drugs allowed an assessment of certain side effects. While there is no definitive proof, weight gain and fluid retention caused by TZD drugs like rosiglitazone are usually thought to be key factors in their increased cardiac risk (Kahn and McGraw, 2010). Rosiglitazone treated mice showed an increase in body weight, an effect persisting for the duration of the experiment (FIG. 4d). This increased mass is accounted for primarily by fluid retention, quantified by a characteristic decrease in hematocrit seen with hemodilution. However, an increase in body fat can also contribute to weight gain and this was observed by MRI (FIGS. 4e and 4f). Importantly, SR1664 treatment did not cause the weight gain seen with the rosiglitazone treatment. Furthermore, SR1664 treatment showed no decrease in the hematocrit or change in body adiposity. These results were confirmed by measurements showing a decreased concentration of hemoglobin in the mice treated with rosiglitazone but not those treated with SR1664. Taken together, these data indicate that SR1664, a non-agonist PPARG ligand, has anti-diabetic actions in two murine models of insulin-resistance. Furthermore, this non-agonist does not stimulate two of the best documented side-effects of the PPARG agonist drugs in vivo. It has unexpectedly been discovered by the inventors that it is possible to create new ligands that have high affinity for PPARG, block the cdk5-mediated phosphorylation and lack classical agonism, and that these new molecular entities can be effective therapeutic agents for a variety of conditions such as type II diabetes.

That classical agonism is not required for strong anti-diabetic actions of a PPARG ligand is clear based on the effects of SR1664 in obese, insulin-resistant mice (FIGS. 3 and 4). In both diet induced obesity and genetically obese animals, SR1664 has clear-cut anti-diabetic actions. The ability to improve adipose tissue insulin sensitivity is similar to the effects shown for rosiglitazone (Mayerson et al., 2002). Using our best calculations to get approximately equal exposure to the two drugs in vivo, SR1664 has very robust anti-diabetic activity, roughly equivalent to rosiglitazone in the experiments shown in FIG. 4.

Side effects of PPARG ligands such as weight gain and fluid retention occur relatively rapidly in both humans and mice. As shown in FIG. 4, increased body weight, increased accretion of fat tissues and increased fluid retention all occur in mice within 11 days of treatment with rosiglitazone. The non-agonist SR1664 shows none of these side effects, even as it is effectively improving glucose homeostasis. Unlike rosiglitazone, SR1664 also does not affect bone cell mineralization in culture (FIG. 2c), though the precise relationship of this assay to bone loss in vivo under the TZD drugs must be considered speculative. However, taken together, these data argue rather strongly that many of the known side effects of the TZD drugs must occur as a consequence of classical agonism on target genes.

Our central hypothesis is that "classical agonism of PPARG correlates with the adverse side effects of TZDs (and likely partial agonists as well), and that the blockage of cdk5-mediated phosphorylation of PPARG correlates with insulin sensitization efficacy"

The compounds we identify as non-agonist PPARG mudulators are non-agonists that are potent blockers of cdk5-mediated phosphorylation of PPARG. Such a compound will have the following properties: 1. High affinity binding to PPARG 2. Minimal or no classical agonism a. Classical agonism is defined as AF-2 mediated coactivator interaction. Coactivator can be anyone of the p160 family or TRAP220 family members, as well as any coactivator shown to interact with PPARG 3. Compound is cell penetrant as determined by the cell based blockage of S273-P in differentiated preadipocytes or when a fixed concentration of compound added to cells alters the transcriptional activity of rosiglitazone on a tandem PPRE::Luc reporter. The compounds do not stimulate increased lipid accumulation or changes in morphology characteristic of differentiating fat cells. 4. Compounds may be antagonist of PPARG but not inverse agonists (they do not repress PPARG target genes).

In vivo such compounds do not increase the expression of a classified agonist gene set but do modulate the cdk5 gene set (Choi et al Nature. 2011 Sep. 4; 477(7365):477-81. doi: 10.1038/nature10383).

We currently believe a compound of the invention (i.e., a compound with the desirable properties recited above) is a compound that shows, at a concentration 10 times its IC50 in the lanthascreen assay, less than 5% transactivation relative to rosiglitazone in a receptor promoter reporter cotransfection assay with wild type human or mouse PPARG and a PPRE reporter. Specific protocols for the two assays, lanthascreen (IC50) and PPRE (EC50), and exemplary results are presented below.

FIG. 5 is a bar graph showing inhibition of production of inflammatory cytokines by SR1664 (compound 73 herein) and rosiglitazone in lipopolysaccharide (LPS) stimulated RAW264.7 cells. The results of this standard assay indicate that a compound of the invention possesses potent anti-inflammatory properties. Accordingly, it is believed that a compound of the invention can be used in the treatment of inflammation, with the potential of avoiding the undesired side-effects described herein that can result from agonism of PPARG.

In various embodiments, the compounds of the invention are not agonists of PPARG; i.e., binding of the compound to PPARG does not activate the receptor, as discussed in greater detail below. In various embodiments, compounds of the invention bring about inhibition of cdk5-mediated phosphorylation of PPARG while being devoid of classical agonism. When the term "modulator" is used herein, the term alludes to a compound of the invention, and it is understood that the terms "modulator" and "compound" or "compound of the invention" are synonymous when the context indicates that a compound of the present invention is being referred to.

The expression "effective amount", when used to describe therapy to an individual suffering from a disorder, refers to the amount of a compound of the invention that is effective to inhibit or otherwise act on PPARG in the individual's tissues wherein PPARG involved in the disorder is active, wherein such inhibition or other action occurs to an extent sufficient to produce a beneficial therapeutic effect.

"Substantially" as the term is used herein means completely or almost completely; for example, a composition that is "substantially free" of a component either has none of the component or contains such a trace amount that any relevant functional property of the composition is unaffected by the presence of the trace amount, or a compound is "substantially pure" is there are only negligible traces of impurities present.

"Treating" or "treatment" within the meaning herein refers to an alleviation of symptoms associated with a disorder or disease, or inhibition of further progression or worsening of those symptoms, or prevention or prophylaxis of the disease or disorder, or curing the disease or disorder. Similarly, as used herein, an "effective amount" or a "therapeutically effective amount" of a compound of the invention refers to an amount of the compound that alleviates, in whole or in part, symptoms associated with the disorder or condition, or halts or slows further progression or worsening of those symptoms, or prevents or provides prophylaxis for the disorder or condition. In particular, a "therapeutically effective amount" refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic result. A therapeutically effective amount is also one in which any toxic or detrimental effects of compounds of the invention are outweighed by the therapeutically beneficial effects.

Phrases such as "under conditions suitable to provide" or "under conditions sufficient to yield" or the like, in the context of methods of synthesis, as used herein refers to reaction conditions, such as time, temperature, solvent, reactant concentrations, and the like, that are within ordinary skill for an experimenter to vary, that provide a useful quantity or yield of a reaction product. It is not necessary that the desired reaction product be the only reaction product or that the starting materials be entirely consumed, provided the desired reaction product can be isolated or otherwise further used.

By "chemically feasible" is meant a bonding arrangement or a compound where the generally understood rules of organic structure are not violated; for example a structure within a definition of a claim that would contain in certain situations a pentavalent carbon atom that would not exist in nature would be understood to not be within the claim. The structures disclosed herein, in all of their embodiments are intended to include only "chemically feasible" structures, and any recited structures that are not chemically feasible, for example in a structure shown with variable atoms or groups, are not intended to be disclosed or claimed herein.

An "analog" of a chemical structure, as the term is used herein, refers to a chemical structure that preserves substantial similarity with the parent structure, although it may not be readily derived synthetically from the parent structure. A related chemical structure that is readily derived synthetically from a parent chemical structure is referred to as a "derivative."

When a substituent is specified to be an atom or atoms of specified identity, "or a bond", a configuration is referred to when the substituent is "a bond" that the groups that are immediately adjacent to the specified substituent are directly connected to each other in a chemically feasible bonding configuration.

All chiral, diastereomeric, racemic forms of a structure are intended, unless a particular stereochemistry or isomeric form is specifically indicated. Compounds used in the present invention can include enriched or resolved optical isomers at any or all asymmetric atoms as are apparent from the depictions, at any degree of enrichment. Both racemic and diastereomeric mixtures, as well as the individual optical isomers can be isolated or synthesized so as to be substantially free of their enantiomeric or diastereomeric partners, and these are all within the scope of the invention.

As used herein, the terms "stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. Only stable compounds are contemplated herein.

A "small molecule" refers to an organic compound, including an organometallic compound, of a molecular weight less than about 2 kDa, that is not a polynucleotide, a polypeptide, a polysaccharide, or a synthetic polymer composed of a plurality of repeating units.

As to any of the groups described herein, which contain one or more substituents, it is understood that such groups do not contain any substitution or substitution patterns which are sterically impractical and/or synthetically non-feasible. In addition, the compounds of this disclosed subject matter include all stereochemical isomers arising from the substitution of these compounds.

Selected substituents within the compounds described herein are present to a recursive degree. In this context, "recursive substituent" means that a substituent may recite another instance of itself. Because of the recursive nature of such substituents, theoretically, a large number may be present in any given claim. One of ordinary skill in the art of medicinal chemistry and organic chemistry understands that the total number of such substituents is reasonably limited by the desired properties of the compound intended. Such properties include, by of example and not limitation, physical properties such as molecular weight, solubility or log P, application properties such as activity against the intended target, and practical properties such as ease of synthesis. Recursive substituents are an intended aspect of the disclosed subject matter. One of ordinary skill in the art of medicinal and organic chemistry understands the versatility of such substituents. To the degree that recursive substituents are present in a claim of the disclosed subject matter, the total number should be determined as set forth above.

When a group, e.g., an "alkyl" group, is referred to without any limitation on the number of atoms in the group, it is understood that the claim is definite and limited with respect the size of the alkyl group, both by definition; i.e., the size (the number of carbon atoms) possessed by a group such as an alkyl group is a finite number, less than the total number of carbon atoms in the universe and bounded by the understanding of the person of ordinary skill as to the size of the group as being reasonable for a molecular entity; and by functionality, i.e., the size of the group such as the alkyl group is bounded by the functional properties the group bestows on a molecule containing the group such as solubility in aqueous or organic liquid media. Therefore, a claim reciting an "alkyl" or other chemical group or moiety is definite and bounded, as the number of atoms in the group cannot be infinite.

The inclusion of an isotopic form of one or more atoms in a molecule that is different from the naturally occurring isotopic distribution of the atom in nature is referred to as an "isotopically labeled form" of the molecule. All isotopic forms of atoms are included as options in the composition of any molecule, unless a specific isotopic form of an atom is indicated. For example, any hydrogen atom or set thereof in a molecule can be any of the isotopic forms of hydrogen, i.e., protium (.sup.1H), deuterium (.sup.2H), or tritium (.sup.3H) in any combination. Similarly, any carbon atom or set thereof in a molecule can be any of the isotopic form of carbons, such as .sup.11C, .sup.12C, .sup.13C, or .sup.14C, or any nitrogen atom or set thereof in a molecule can be any of the isotopic forms of nitrogen, such as .sup.13N, .sup.14N, or .sup.15N. A molecule can include any combination of isotopic forms in the component atoms making up the molecule, the isotopic form of every atom forming the molecule being independently selected. In a multi-molecular sample of a compound, not every individual molecule necessarily has the same isotopic composition. For example, a sample of a compound can include molecules containing various different isotopic compositions, such as in a tritium or .sup.14C radiolabeled sample where only some fraction of the set of molecules making up the macroscopic sample contains a radioactive atom. It is also understood that many elements that are not artificially isotopically enriched themselves are mixtures of naturally occurring isotopic forms, such as .sup.14N and .sup.15N, .sup.32S and .sup.34S, and so forth. A molecule as recited herein is defined as including isotopic forms of all its constituent elements at each position in the molecule. As is well known in the art, isotopically labeled compounds can be prepared by the usual methods of chemical synthesis, except substituting an isotopically labeled precursor molecule. The isotopes, radiolabeled or stable, can be obtained by any method known in the art, such as generation by neutron absorption of a precursor nuclide in a nuclear reactor, by cyclotron reactions, or by isotopic separation such as by mass spectrometry. The isotopic forms are incorporated into precursors as required for use in any particular synthetic route. For example, .sup.14C and .sup.3H can be prepared using neutrons generated in a nuclear reactor. Following nuclear transformation, .sup.14C and .sup.3H are incorporated into precursor molecules, followed by further elaboration as needed.

The term "amino protecting group" or "N-protected" as used herein refers to those groups intended to protect an amino group against undesirable reactions during synthetic procedures and which can later be removed to reveal the amine. Commonly used amino protecting groups are disclosed in Protective Groups in Organic Synthesis, Greene, T. W.; Wuts, P. G. M., John Wiley & Sons, New York, N.Y., (3rd Edition, 1999).

Typically, amino protecting groups include formyl, acetyl, benzoyl, pivaloyl, t-butylacetyl, phenylsulfonyl, Alloc, Teoc, benzyl, Fmoc, Boc and Cbz. It is well within the skill of the ordinary artisan to select and use the appropriate amino protecting group for the synthetic task at hand.

In general, "substituted" refers to an organic group as defined herein in which one or more bonds to a hydrogen atom contained therein are replaced by one or more bonds to a non-hydrogen atom such as, but not limited to, a halogen (i.e., F, Cl, Br, and I); an oxygen atom in groups such as hydroxyl groups, alkoxy groups, aryloxy groups, aralkyloxy groups, oxo(carbonyl) groups, carboxyl groups including carboxylic acids, carboxylates, and carboxylate esters; a sulfur atom in groups such as thiol groups, alkyl and aryl sulfide groups, sulfoxide groups, sulfone groups, sulfonyl groups, and sulfonamide groups; a nitrogen atom in groups such as amines, hydroxylamines, nitriles, nitro groups, N-oxides, hydrazides, azides, and enamines; and other heteroatoms in various other groups. Non-limiting examples of substituents J that can be bonded to a substituted carbon (or other) atom include F, Cl, Br, I, OR', OC(O)N(R').sub.2, CN, NO, NO.sub.2, ONO.sub.2, azido, CF.sub.3, OCF.sub.3, R', O (oxo), S (thiono), methylenedioxy, ethylenedioxy, N(R').sub.2, SR, SOR', SO.sub.2R', SO.sub.2N(R').sub.2, SO.sub.3R', C(O)R', C(O)C(O)R', C(O)CH.sub.2C(O)R', C(S)R', C(O)OR', OC(O)R', C(O)N(R').sub.2, OC(O)N(R').sub.2, C(S)N(R').sub.2, (CH.sub.2).sub.0-2N(R')C(O)R', (CH.sub.2).sub.0-2N(R')N(R').sub.2, N(R')N(R')C(O)R', N(R')N(R')C(O)OR', N(R')N(R')CON(R').sub.2, N(R')SO.sub.2R', N(R')SO.sub.2N(R').sub.2, N(R')C(O)OR', N(R')C(O)R', N(R')C(S)R', N(R')C(O)N(R').sub.2, N(R')C(S)N(R').sub.2, N(COR')COR', N(OR')R', C(.dbd.NH)N(R').sub.2, C(O)N(OR')R', or C(.dbd.NOR')R' wherein R' can be hydrogen or a carbon-based moiety, and wherein the carbon-based moiety can itself be further substituted; for example, wherein R' can be hydrogen, alkyl, acyl, cycloalkyl, aryl, aralkyl, heterocyclyl, heteroaryl, or heteroarylalkyl, wherein any alkyl, acyl, cycloalkyl, aryl, aralkyl, heterocyclyl, heteroaryl, or heteroarylalkyl or R' can be independently mono- or multi-substituted with J; or wherein two R' groups bonded to a nitrogen atom or to adjacent nitrogen atoms can together with the nitrogen atom or atoms form a heterocyclyl, which can be mono- or independently multi-substituted with J.

When a substituent is monovalent, such as, for example, F or Cl, it is bonded to the atom it is substituting by a single bond. When a substituent is more than monovalent, such as O, which is divalent, it can be bonded to the atom it is substituting by more than one bond, i.e., a divalent substituent is bonded by a double bond; for example, a C substituted with O forms a carbonyl group, C.dbd.O, which can also be written as "CO", "C(O)", or "C(.dbd.O)", wherein the C and the O are double bonded. When a carbon atom is substituted with a double-bonded oxygen (.dbd.O) group, the oxygen substituent is termed an "oxo" group. When a divalent substituent such as NR is double-bonded to a carbon atom, the resulting C(.dbd.NR) group is termed an "imino" group. When a divalent substituent such as S is double-bonded to a carbon atom, the results C(.dbd.S) group is termed a "thiocarbonyl" or "thiono" group.

Alternatively, a divalent substituent such as O or S can be connected by two single bonds to two different carbon atoms. For example, O, a divalent substituent, can be bonded to each of two adjacent carbon atoms to provide an epoxide group, or the O can form a bridging ether group, termed an "oxy" group, between adjacent or non-adjacent carbon atoms, for example bridging the 1,4-carbons of a cyclohexyl group to form a [2.2.1]-oxabicyclo system. Further, any substituent can be bonded to a carbon or other atom by a linker, such as (CH.sub.2).sub.n or (CR'.sub.2).sub.n wherein n is 1, 2, 3, or more, and each R' is independently selected.

C(O) and S(O).sub.2 groups can also be bound to one or two heteroatoms, such as nitrogen or oxygen, rather than to a carbon atom. For example, when a C(O) group is bound to one carbon and one nitrogen atom, the resulting group is called an "amide" or "carboxamide." When a C(O) group is bound to two nitrogen atoms, the functional group is termed a "urea." When a C(O) is bonded to one oxygen and one nitrogen atom, the resulting group is termed a "carbamate" or "urethane." When a S(O).sub.2 group is bound to one carbon and one nitrogen atom, the resulting unit is termed a "sulfonamide." When a S(O).sub.2 group is bound to two nitrogen atoms, the resulting unit is termed a "sulfamate."

Substituted alkyl, alkenyl, alkynyl, cycloalkyl, and cycloalkenyl groups as well as other substituted groups also include groups in which one or more bonds to a hydrogen atom are replaced by one or more bonds, including double or triple bonds, to a carbon atom, or to a heteroatom such as, but not limited to, oxygen in carbonyl (oxo), carboxyl, ester, amide, imide, urethane, and urea groups; and nitrogen in imines, hydroxyimines, oximes, hydrazones, amidines, guanidines, and nitriles.

Substituted ring groups such as substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups also include rings and fused ring systems in which a bond to a hydrogen atom is replaced with a bond to a carbon atom. Therefore, substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups can also be substituted with alkyl, alkenyl, and alkynyl groups as defined herein.

By a "ring system" as the term is used herein is meant a moiety comprising one, two, three or more rings, which can be substituted with non-ring groups or with other ring systems, or both, which can be fully saturated, partially unsaturated, fully unsaturated, or aromatic, and when the ring system includes more than a single ring, the rings can be fused, bridging, or spirocyclic. By "spirocyclic" is meant the class of structures wherein two rings are fused at a single tetrahedral carbon atom, as is well known in the art.

As to any of the groups described herein, which contain one or more substituents, it is understood, of course, that such groups do not contain any substitution or substitution patterns which are sterically impractical and/or synthetically non-feasible.

Representative substituted cycloalkyl groups can be mono-substituted or substituted more than once, such as, but not limited to, 2,2-, 2,3-, 2,4-2,5- or 2,6-disubstituted cyclohexyl groups or mono-, di- or tri-substituted norbornyl or cycloheptyl groups, which can be substituted with, for example, amino, hydroxy, cyano, carboxy, nitro, thio, alkoxy, and halogen groups. The term "cycloalkenyl" alone or in combination denotes a cyclic alkenyl group.

The terms "carbocyclic," "carbocyclyl," and "carbocycle" denote a ring structure wherein the atoms of the ring are carbon, such as a cycloalkyl group or an aryl group. In some embodiments, the carbocycle has 3 to 8 ring members, whereas in other embodiments the number of ring carbon atoms is 4, 5, 6, or 7. Unless specifically indicated to the contrary, the carbocyclic ring can be substituted with as many as N-1 substituents wherein N is the size of the carbocyclic ring with, for example, alkyl, alkenyl, alkynyl, amino, aryl, hydroxy, cyano, carboxy, heteroaryl, heterocyclyl, nitro, thio, alkoxy, and halogen groups, or other groups as are listed above. A carbocyclyl ring can be a cycloalkyl ring, a cycloalkenyl ring, or an aryl ring.

The heteroatom(s) may be placed at any position of the heteroalkyl group, including between the rest of the heteroalkyl group and the fragment to which it is attached, as well as attached to the most distal carbon atom in the heteroalkyl group. Examples include: --O--CH.sub.2--CH.sub.2--CH.sub.3, --CH.sub.2--CH.sub.2CH.sub.2--OH, --CH.sub.2--CH.sub.2--NH--CH.sub.3, --CH.sub.2--S--CH.sub.2--CH.sub.3, --CH.sub.2CH.sub.2--S(.dbd.O)--CH.sub.3, and --CH.sub.2CH.sub.2--O--CH.sub.2CH.sub.2--O--CH.sub.3.

Representative aralkyl groups include benzyl and phenylethyl groups and fused (cycloalkylaryl)alkyl groups such as 4-ethyl-indanyl. Aralkenyl group are alkenyl groups as defined above in which a hydrogen or carbon bond of an alkyl group is replaced with a bond to an aryl group as defined above.

Heterocyclyl groups or the term "heterocyclyl" includes aromatic and non-aromatic ring compounds containing 3 or more ring members, of which, one or more is a heteroatom such as, but not limited to, N, O, and S. Thus a heterocyclyl can be a cycloheteroalkyl, or a heteroaryl, or if polycyclic, any combination thereof.

In some embodiments, heterocyclyl groups include 3 to about 20 ring members, whereas other such groups have 3 to about 15 ring members. A heterocyclyl group designated as a C.sub.2-heterocyclyl can be a 5-ring with two carbon atoms and three heteroatoms, a 6-ring with two carbon atoms and four heteroatoms and so forth. Likewise a C.sub.4-heterocyclyl can be a 5-ring with one heteroatom, a 6-ring with two heteroatoms, and so forth. The number of carbon atoms plus the number of heteroatoms sums up to equal the total number of ring atoms. A heterocyclyl ring can also include one or more double bonds. A heteroaryl ring is an embodiment of a heterocyclyl group. The phrase "heterocyclyl group" includes fused ring species including those comprising fused aromatic and non-aromatic groups.

A "zwitterion" is an internal salt such as can be formed in a molecule that has at least two ionizable groups, one forming an anion and the other a cation, which serve to balance each other. For example, amino acids such as glycine can exist in a zwitterionic form. A "zwitterion" is a salt within the meaning herein. The compounds of the present invention may take the form of salts. The term "salts" embraces addition salts of free acids or free bases which are compounds of the invention. Salts can be "pharmaceutically-acceptable salts." The term "pharmaceutically-acceptable salt" refers to salts which possess toxicity profiles within a range that affords utility in pharmaceutical applications. Pharmaceutically unacceptable salts may nonetheless possess properties such as high crystallinity, which have utility in the practice of the present invention, such as for example utility in process of synthesis, purification or formulation of compounds of the invention.

Suitable pharmaceutically-acceptable acid addition salts may be prepared from an inorganic acid or from an organic acid. Examples of inorganic acids include hydrochloric, hydrobromic, hydriodic, nitric, carbonic, sulfuric, and phosphoric acids.

All of these salts may be prepared by conventional means from the corresponding compound according to Formula (I) by reacting, for example, the appropriate acid or base with the compound according to Formula (I). The term "pharmaceutically acceptable salts" refers to nontoxic inorganic or organic acid and/or base addition salts, see, for example, Lit et al., Salt Selection for Basic Drugs (1986), Int J. Pharm., 33, 201-217, incorporated by reference herein.

A "hydrate" is a compound that exists in a composition with water molecules. The composition can include water in stoichiometric quantities, such as a monohydrate or a dihydrate, or can include water in random amounts. As the term is used herein a "hydrate" refers to a solid form, i.e., a compound in water solution, while it may be hydrated, is not a hydrate as the term is used herein.

A "solvate" is a similar composition except that a solvent other that water replaces the water. For example, methanol or ethanol can form an "alcoholate", which can again be stoichiometric or non-stoichiometric. As the term is used herein a "solvate" refers to a solid form, i.e., a compound in solution in a solvent, while it may be solvated, is not a solvate as the term is used herein.

A "prodrug" as is well known in the art is a substance that can be administered to a patient where the substance is converted in vivo by the action of biochemicals within the patients body, such as enzymes, to the active pharmaceutical ingredient. Examples of prodrugs include esters of carboxylic acid groups, which can be hydrolyzed by endogenous esterases as are found in the bloodstream of humans and other mammals. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in "Design of Prodrugs", ed. H. Bundgaard, Elsevier, 1985.

In addition, where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any individual member or subgroup of members of the Markush group. For example, if X is described as selected from the group consisting of bromine, chlorine, and iodine, claims for X being bromine and claims for X being bromine and chlorine are fully described. Moreover, where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any combination of individual members or subgroups of members of Markush groups. Thus, for example, if X is described as selected from the group consisting of bromine, chlorine, and iodine, and Y is described as selected from the group consisting of methyl, ethyl, and propyl, claims for X being bromine and Y being methyl are fully described.

If a value of a variable that is necessarily an integer, e.g., the number of carbon atoms in an alkyl group or the number of substituents on a ring, is described as a range, e.g., 0-4, what is meant is that the value can be any integer between 0 and 4 inclusive, i.e., 0, 1, 2, 3, or 4.

Provisos may apply to any of the disclosed categories or embodiments wherein any one or more of the other above disclosed embodiments or species may be excluded from such categories or embodiments.

The present invention further embraces isolated compounds of the invention. The expression "isolated compound" refers to a preparation of a compound of the invention, or a mixture of compounds the invention, wherein the isolated compound has been separated from the reagents used, and/or byproducts formed, in the synthesis of the compound or compounds. "Isolated" does not mean that the preparation is technically pure (homogeneous), but it is sufficiently pure to compound in a form in which it can be used therapeutically. Preferably an "isolated compound" refers to a preparation of a compound of the invention or a mixture of compounds of the invention, which contains the named compound or mixture of compounds of the invention in an amount of at least 10 percent by weight of the total weight. Preferably the preparation contains the named compound or mixture of compounds in an amount of at least 50 percent by weight of the total weight; more preferably at least 80 percent by weight of the total weight; and most preferably at least 90 percent, at least 95 percent or at least 98 percent by weight of the total weight of the preparation.

Isomerism and Tautomerism in Compounds of the Invention

Tautomerism

Within the present invention it is to be understood that a compound of the formula (I) or a salt thereof may exhibit the phenomenon of tautomerism whereby two chemical compounds that are capable of facile interconversion by exchanging a hydrogen atom between two atoms, to either of which it forms a covalent bond. Since the tautomeric compounds exist in mobile equilibrium with each other they may be regarded as different isomeric forms of the same compound. It is to be understood that the formulae drawings within this specification can represent only one of the possible tautomeric forms. However, it is also to be understood that the invention encompasses any tautomeric form, and is not to be limited merely to any one tautomeric form utilized within the formulae drawings. The formulae drawings within this specification can represent only one of the possible tautomeric forms and it is to be understood that the specification encompasses all possible tautomeric forms of the compounds drawn not just those forms which it has been convenient to show graphically herein. For example, tautomerism may be exhibited by a pyrazolyl group bonded as indicated by the wavy line. While both substituents would be termed a 4-pyrazolyl group, it is evident that a different nitrogen atom bears the hydrogen atom in each structure.

##STR00003##

Such tautomerism can also occur with substituted pyrazoles such as 3-methyl, 5-methyl, or 3,5-dimethylpyrazoles, and the like. Another example of tautomerism is amido-imido (lactam-lactim when cyclic) tautomerism, such as is seen in heterocyclic compounds bearing a ring oxygen atom adjacent to a ring nitrogen atom. For example, the equilibrium:

##STR00004## is an example of tautomerism. Accordingly, a structure depicted herein as one tautomer is intended to also include the other tautomer. Optical Isomerism

It will be understood that when compounds of the present invention contain one or more chiral centers, the compounds may exist in, and may be isolated as pure enantiomeric or diastereomeric forms or as racemic mixtures. The present invention therefore includes any possible enantiomers, diastereomers, racemates or mixtures thereof of the compounds of the invention.

The isomers resulting from the presence of a chiral center comprise a pair of non-superimposable isomers that are called "enantiomers." Single enantiomers of a pure compound are optically active, i.e., they are capable of rotating the plane of plane polarized light. Single enantiomers are designated according to the Cahn-Ingold-Prelog system. The priority of substituents is ranked based on atomic weights, a higher atomic weight, as determined by the systematic procedure, having a higher priority ranking. Once the priority ranking of the four groups is determined, the molecule is oriented so that the lowest ranking group is pointed away from the viewer. Then, if the descending rank order of the other groups proceeds clockwise, the molecule is designated (R) and if the descending rank of the other groups proceeds counterclockwise, the molecule is designated (S). In the example in Scheme 14, the Cahn-Ingold-Prelog ranking is A>B>C>D. The lowest ranking atom, D is oriented away from the viewer.

##STR00005##

The present invention is meant to encompass diastereomers as well as their racemic and resolved, diastereomerically and enantiomerically pure forms and salts thereof. Diastereomeric pairs may be resolved by known separation techniques including normal and reverse phase chromatography, and crystallization.

"Isolated optical isomer" means a compound which has been substantially purified from the corresponding optical isomer(s) of the same formula. Preferably, the isolated isomer is at least about 80% pure, more preferably at least 90% pure, even more preferably at least 98% pure, most preferably at least about 99% pure, by weight.

Isolated optical isomers may be purified from racemic mixtures by well-known chiral separation techniques. According to one such method, a racemic mixture of a compound of the invention, or a chiral intermediate thereof, is separated into 99% wt. % pure optical isomers by HPLC using a suitable chiral column, such as a member of the series of DAICEL.RTM. CHIRALPAK.RTM. family of columns (Daicel Chemical Industries, Ltd., Tokyo, Japan). The column is operated according to the manufacturer's instructions.

Rotational Isomerism

It is understood that due to chemical properties (i.e., resonance lending some double bond character to the C--N bond) of restricted rotation about the amide bond linkage (as illustrated below) it is possible to observe separate rotamer species and even, under some circumstances, to isolate such species (see below). It is further understood that certain structural elements, including steric bulk or substituents on the amide nitrogen, may enhance the stability of a rotamer to the extent that a compound may be isolated as, and exist indefinitely, as a single stable rotamer. The present invention therefore includes any possible stable rotamers of formula (I) which are biologically active in the treatment of cancer or other proliferative disease states.

##STR00006## Regioisomerism

The preferred compounds of the present invention have a particular spatial arrangement of substituents on the aromatic rings, which is related to the structure activity relationship demonstrated by the compound class. Often such substitution arrangement is denoted by a numbering system; however, numbering systems are often not consistent between different ring systems. In six-membered aromatic systems, the spatial arrangements are specified by the common nomenclature "para" for 1,4-substitution, "meta" for 1,3-substitution and "ortho" for 1,2-substitution as shown below.

##STR00007##

In various embodiments, the compound or set of compounds, such as are among the inventive compounds or are used in the inventive methods, can be any one of any of the combinations and/or sub-combinations of the above-listed embodiments.

For example, the active compound will usually be mixed with a carrier, or diluted by a carrier, or enclosed within a carrier which can be in the form of an ampoule, capsule, sachet, paper, or other container. When the active compound is mixed with a carrier, or when the carrier serves as a diluent, it can be solid, semi-solid, or liquid material that acts as a vehicle, excipient, or medium for the active compound. The active compound can be adsorbed on a granular solid carrier, for example contained in a sachet. Some examples of suitable carriers are water, salt solutions, alcohols, polyethylene glycols, polyhydroxyethoxylated castor oil, peanut oil, olive oil, gelatin, lactose, terra alba, sucrose, dextrin, magnesium carbonate, sugar, cyclodextrin, amylose, magnesium stearate, talc, gelatin, agar, pectin, acacia, stearic acid or lower alkyl ethers of cellulose, silicic acid, fatty acids, fatty acid amines, fatty acid monoglycerides and diglycerides, pentaerythritol fatty acid esters, polyoxyethylene, hydroxymethylcellulose and polyvinylpyrrolidone. Similarly, the carrier or diluent can include any sustained release material known in the art, such as glyceryl monostearate or glyceryl distearate, alone or mixed with a wax.

The formulations can be mixed with auxiliary agents which do not deleteriously react with the active compounds. Such additives can include wetting agents, emulsifying and suspending agents, salt for influencing osmotic pressure, buffers and/or coloring substances preserving agents, sweetening agents or flavoring agents. The compositions can also be sterilized if desired.

The route of administration can be any route which effectively transports the active compound of the invention to the appropriate or desired site of action, such as oral, nasal, pulmonary, buccal, subdermal, intradermal, transdermal or parenteral, e.g., rectal, depot, subcutaneous, intravenous, intraurethral, intramuscular, intranasal, ophthalmic solution or an ointment, the oral route being preferred.

If a solid carrier is used for oral administration, the preparation can be tableted, placed in a hard gelatin capsule in powder or pellet form or it can be in the form of a troche or lozenge. If a liquid carrier is used, the preparation can be in the form of a syrup, emulsion, soft gelatin capsule or sterile injectable liquid such as an aqueous or non-aqueous liquid suspension or solution.

Injectable dosage forms generally include aqueous suspensions or oil suspensions which can be prepared using a suitable dispersant or wetting agent and a suspending agent Injectable forms can be in solution phase or in the form of a suspension, which is prepared with a solvent or diluent. Acceptable solvents or vehicles include sterilized water, Ringer's solution, or an isotonic aqueous saline solution. Alternatively, sterile oils can be employed as solvents or suspending agents. Preferably, the oil or fatty acid is non-volatile, including natural or synthetic oils, fatty acids, mono-, di- or tri-glycerides.

For injection, the formulation can also be a powder suitable for reconstitution with an appropriate solution as described above. Examples of these include, but are not limited to, freeze dried, rotary dried or spray dried powders, amorphous powders, granules, precipitates, or particulates. For injection, the formulations can optionally contain stabilizers, pH modifiers, surfactants, bioavailability modifiers and combinations of these. The compounds can be formulated for parenteral administration by injection such as by bolus injection or continuous infusion. A unit dosage form for injection can be in ampoules or in multi-dose containers.

The formulations of the invention can be designed to provide quick, sustained, or delayed release of the active ingredient after administration to the patient by employing procedures well known in the art. Thus, the formulations can also be formulated for controlled release or for slow release.

Compositions contemplated by the present invention can include, for example, micelles or liposomes, or some other encapsulated form, or can be administered in an extended release form to provide a prolonged storage and/or delivery effect. Therefore, the formulations can be compressed into pellets or cylinders and implanted intramuscularly or subcutaneously as depot injections. Such implants can employ known inert materials such as silicones and biodegradable polymers, e.g., polylactide-polyglycolide. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides).

For nasal administration, the preparation can contain a compound of the invention, dissolved or suspended in a liquid carrier, preferably an aqueous carrier, for aerosol application. The carrier can contain additives such as solubilizing agents, e.g., propylene glycol, surfactants, absorption enhancers such as lecithin (phosphatidylcholine) or cyclodextrin, or preservatives such as parabens.

For parenteral application, particularly suitable are injectable solutions or suspensions, preferably aqueous solutions with the active compound dissolved in polyhydroxylated castor oil.

Tablets, dragees, or capsules having talc and/or a carbohydrate carrier or binder or the like are particularly suitable for oral application. Preferable carriers for tablets, dragees, or capsules include lactose, corn starch, and/or potato starch. A syrup or elixir can be used in cases where a sweetened vehicle can be employed.

A typical tablet that can be prepared by conventional tabletting techniques can contain:

TABLE-US-00001 Core: Active compound (as free compound or salt thereof) 250 mg Colloidal silicon dioxide (Aerosil .RTM.) 1.5 mg Cellulose, microcryst. (Avicel .RTM.) 70 mg Modified cellulose gum (Ac-Di-Sol .RTM.) 7.5 mg Magnesium stearate Ad. Coating: HPMC approx. 9 mg *Mywacett 9-40 T approx. 0.9 mg *Acylated monoglyceride used as plasticizer for film coating.

A typical capsule for oral administration contains compounds of the invention (250 mg), lactose (75 mg) and magnesium stearate (15 mg). The mixture is passed through a 60 mesh sieve and packed into a No. 1 gelatin capsule. A typical injectable preparation is produced by aseptically placing 250 mg of compounds of the invention into a vial, aseptically freeze-drying and sealing. For use, the contents of the vial are mixed with 2 mL of sterile physiological saline, to produce an injectable preparation.

The compounds of the invention can be administered to a mammal, especially a human in need of such treatment, prevention, elimination, alleviation or amelioration of a condition. Such mammals include also animals, both domestic animals, e.g., household pets, farm animals, and non-domestic animals such as wildlife.

The compounds of the invention are effective over a wide dosage range. For example, in the treatment of adult humans, dosages from about 0.05 to about 5000 mg, preferably from about 1 to about 2000 mg, and more preferably between about 2 and about 2000 mg per day can be used. A typical dosage is about 10 mg to about 1000 mg per day. In choosing a regimen for patients it can frequently be necessary to begin with a higher dosage and when the condition is under control to reduce the dosage. The exact dosage will depend upon the activity of the compound, mode of administration, on the therapy desired, form in which administered, the subject to be treated and the body weight of the subject to be treated, and the preference and experience of the physician or veterinarian in charge.

Generally, the compounds of the invention are dispensed in unit dosage form including from about 0.05 mg to about 1000 mg of active ingredient together with a pharmaceutically acceptable carrier per unit dosage.

Usually, dosage forms suitable for oral, nasal, pulmonal or transdermal administration include from about 125 .mu.g to about 1250 mg, preferably from about 250 .mu.g to about 500 mg, and more preferably from about 2.5 mg to about 250 mg, of the compounds admixed with a pharmaceutically acceptable carrier or diluent.

Dosage forms can be administered daily, or more than once a day, such as twice or thrice daily. Alternatively dosage forms can be administered less frequently than daily, such as every other day, or weekly, if found to be advisable by a prescribing physician.

Methods of the Invention

In various embodiments, the invention provides methods of inhibiting kinase-mediated, such as cdk5-mediated, phosphorylation of PPARG in a mammal, comprising administering to the mammal an effective amount of a compound of the invention. The effective amount of the compound for inhibiting, e.g., cdk5-mediated phosphorylation of PPARG can avoid producing an agonistic effect on PPARG. By avoiding agonism of PPARG, various side effects can be avoided, including such as significant weight gain, edema, impairment of bone growth or formation, or cardiac hypertrophy, or any combination thereof.

In various embodiments, the invention provides a method of treating a condition in a mammal, wherein binding of a ligand to PPARG or inhibition of, e.g., cdk5-mediated phosphorylation of PPARG, or both, is medically indicated, comprising administering to the mammal an effective amount of a compound of the invention at a frequency of dosing and for a duration of dosing effective to provide a beneficial effect to the mammal. The mammal under treatment can be a human. In various embodiments, the effective amount, frequency of dosing, and duration of dosing of the compound for binding of a ligand to PPARG or inhibition of cdk5-mediated phosphorylation of PPARG, or both, do not produce an agonistic effect on PPARG. For example, administration of a compound of the invention can be used for treatment of diabetes, insulin resistance, impaired glucose tolerance, pre-diabetes, hyperglycemia, hyperinsulinemia, obesity, or inflammation. Due to the avoidance of agonism of PPARG, an effective amount, frequency of dosing, and duration of dosing of the compound does not significantly produce side effects of weight gain, edema, or cardiac hypertrophy in the mammal receiving the compound.

Specifically, the invention provides a method of treatment of diabetes in a human, comprising administering to the human regularly over a duration of time an effective amount of a compound of the invention, optionally in conjunction with a second medicament effective for the treatment of diabetes. More specifically the compound can be

##STR00012## or a pharmaceutically acceptable salt thereof. When the compound of the invention is used in combination with a second medicament comprising an effective antidiabetes agent, the second agent can be any suitable drug approved for diabetes treatment, such as biguanides such as metformin and the like, sulfonylureas such as gliburide and the like, or thiazolidinediones such as rosiglitazone and the like.

Bioassay Procedures

Lanthascreen PPARG Competitive Binding Assay (Invitrogen)

The assay was performed according to manufacturer protocol. A mixture of nM GST-PPARG-LBD, 5 nM Tb-GST-antibody, 5 nM Fluormone Pan-PPAR Green, and serial dilutions of the experimental compound, beginning at 10 .mu.M downwards, was added to wells of black 384-well low-volume plates (Greiner) to a total volume of 18 .mu.L. All dilutions were made in TR-FRET assay buffer C. DMSO at 2% final concentration was used as a no-ligand control. Experiment was performed in triplicate, and incubated for 2 hours in the dark prior to assay read in Perkin Elmer ViewLux ultra HTS microplate reader. FRET signal was measured by excitation at 340 nm and emission at 520 nm for fluorescein and 490 nm for terbium. Fold change over DMSO was calculated using GraphPad Prism Software (La Jolla, Calif.) by calculating 520 nm/490 nm ratio. Graphs were plotted as fold change of FRET signal for compound treatment over DMSO-only control.

Cell-Based Transactivation Assay:

PPRE is a DNA that contains a binding site for PPARG; thus PPRE is a PPAR response element, used herein as a promoter reporter. The binding site is a DR1 response element with the sequence AGGTCA repeated 3 times in tandem and then fused to a construct for luciferase.

Thus, PPRE is the basis of the cell based transactivation assay described below. The plasmid DNA is co-transfected along with a plasmid for PPARG into COS-1 cells. After an overnight incubation, cells are treated with DMSO or compounds. In this assay rosiglitazone activates the reporter about 5 fold. Partial agonists such as MRL24 transactivate the reporter about 25% of rosiglitazone response. Compounds of the invention which are non-activators afford no transactivation of the reporter.

Confluent COS-1 cells were transfected with 4.5 .mu.g murine PPARg2-pSV Sport or full-length human PPAR9-pSport6, 4.5 .mu.g 3.times.PPRE-luciferase reporter and 27 .mu.L X-treme Gene 9 transfection reagent in serum-free opti-mem media (Gibco), followed by overnight incubation at 37.degree. C., 5% CO.sub.2. Transfected cells were plated in white Perkin Elmer 384-well plates and incubated 4 hours. Cells were treated with DMSO vehicle only or experimental compounds in increasing doses from 2 .mu.M-220 .mu.M for mouse receptor and 10 .mu.M-111 fM for human. After 18 hour incubation, treated cells were developed with Brite Lite Plus (Perkin Elmer) and read in 384-well Luminescence Perkin Elmer EnVision Multilabel plate reader. Graphs were plotted in triplicate in GraphPad Prism Software as fold change of treated cells over DMSO control cells.

The human PPAR nuclear receptor ligand binding domain (LBD) is fused to the DNA-Binding Domain of the yeast GAL4 transcription factor. The hybrid fusion-protein nuclear receptor can activate the luciferase reporter under the control of the GAL4 Upstream Activator Sequence (UAS).

The plasmid Gal-4-PPAR DNA is co-transfected along with a plasmid for UAS-luc into HEK 293T cells. After an overnight incubation, cells are treated with DMSO or compounds. In this assay rosiglitazone activates the reporter about 100-fold. Partial agonists transactivate the reporter about 30-40% of rosiglitazone response. Compounds of the invention which are non-activators exhibit <5% transactivation of the receptor at 1 .mu.M.

HEK 293T cells were transfected with 4.5 .mu.g of Gal-4-PPAR9, 4.5 .mu.g UAS-luciferase reporter and 27 .mu.L X-treme Gene 9 transfection reagent in serum-free opti-mem media (Gibco), followed by overnight incubation at 37.degree. C., 5% CO.sub.2. Transfected cells were replated in white Perkin Elmer 384-well plates and incubated 4 hours. Cells were treated with DMSO vehicle only or experimental compounds in doses from 10 .mu.M-111 fM. After 18 hour incubation, treated cells were developed with Brite Lite Plus (Perkin Elmer) and read in 384-well Luminescence Perkin Elmer EnVision Multilabel plate reader. Graphs were plotted in triplicate in GraphPad Prism Software as fold change of treated cells over DMSO control cells.
