Compositions and methods for treating hyperproliferative diseases

BACKGROUND

According to the World Health Organization, there are five million people dying from cancer every year. Drug treatment is one of the three major therapies for cancer. At present, the anticancer directions are as follows: Interfere with or inhibit cell division, Regulate cell generation cycle, Promote tumor cell to apoptosis, Inhibit angiogenesis, Inhibit oncogene, Promote tumor suppressing gene, Tumor antigen, Inhibitor of telomerase and Interfere with information transfer of tumor cells.

In view of the high mortality rates associated with abnormal proliferative diseases including cancer, there exists a need in the art for an effective treatment for benign proliferative diseases as well as cancer.

SUMMARY

This invention is based on the discovery that a combination of certain known drugs is effective in treating hyperproliferative diseases including cancer.

In one aspect, the invention features a composition that includes (A) a first agent that possesses anti-inflammatory activity or acetaminophen, phenacetin, tramadol and the like, a second agent (B) that can be an oxidative phosphorylation inhibitor, an ionophore, or an adenosine 5'-monophosphate-activated Protein kinase (AMPK) activator, and a third agent (C) that possesses or maintains serotonin activity.

The first agent can be any suitable anti-inflammatory compound (e.g., non-steroidal anti-inflammatory compounds) or acetaminophen, phenacetin, tramadol and the like. Examples include aspirin, diclofenac (e.g., diclofenac potassium or diclofenac sodium), ibuprofen (e.g., dexibuprofen or dexibuprofen lysine), indomethacin, nimesulide, and a COX-2 inhibitor (e.g., a nitric oxide-based COX-2 inhibitor or Celebrex.RTM. (4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl] benzenesulfonamide)). Other examples of the first agent include Aspirin-arginine, Alxiling, L-arginine acetylsalicylic; Aspirin-DL-lysine; Bismuth Salicylate Basic; Bismuth salicylate; Magnesium Salicylate; Diethylamine Salicylate; Salicylic acid, sodium salt; imidazole salicylate; Sodium Aminosalicylate; Isoniazid Aminosalicylate; Physostigmine Salicylate; Pregnenolone Acetylsalicylate; Choline Magnesium Trisalycylate (Trilisate); Salicylic Acid Zinc Oxide; Sodium Salicylate and Sodium Iodide; Salicylic Acid and Acetic Acid Glacial Solution; and Methyl Salicylate.

The second agent is an oxidative phosphorylation inhibitor, ionophore or AMPK activator). The term "oxidative phosphorylation inhibitor" refers to any suitable agents that inhibit oxidative phosphorylation, such as oxidative phosphorylation uncouplers. An ionophore is a lipid-soluble molecule capable of transporting an ion across the lipid bilayer of cell membranes; and an AMPK activator is an agent that activates AMPK to phosphorylate its substrates, e.g., acetyl-CoA carboxylase and malonyl-CoA decarboxylase. Examples of the second agent include metformin (e.g., metformin chloride), phenformin and buformin.

The third agent can be a compound possessing or maintaining at least one of the serotonin's activities and, when used in combination with the first and second agents, effectively treats one or more of the target diseases of this invention. Examples include serotonin (e.g., serotonin sulfate, serotonin creatinine sulfate complex, or serotonin hydrochloride) and a serotonin re-uptake inhibitor.

A preferred composition of the present invention contains aspirin, metformin hydrochloride, and serotonin creatinine sulfate complex.

In another aspect, the invention features a composition consisting essentially of a first agent that possesses anti-inflammatory activity or acetaminophen, phenacetin, tramadol and the like, a second agent that can be an oxidative phosphorylation inhibitor, an ionophore, or an AMPK activator, and a third agent that possesses serotonin activity. The term "consisting essentially of" used herein limits a composition to the three specified agents and those that do not materially affect its basic and novel characteristics, i.e., the efficacy in treating a target disease described herein. An example of such a composition contains the above-mentioned three agents and a pharmaceutically acceptable carrier. The compositions described above can contain 5-5,000 mg (e.g., 5-3,000 mg, 5-1,500 mg or 5-1,000 mg) of the first agent, 1-5,000 mg (e.g., 1-3000 mg, 1-1,000 mg, 1-500 mg, or 1-100 mg) of the second agent, and 0.1-1,000 mg (e.g., 0.1-100 mg, 0.1-50 mg, or 0.1-30 mg) of the third agent, or in quantities of the same ratio as that calculated based on the above amounts.

In still another aspect, the invention features a method for treating hyperproliferative diseases. The method includes administering to a subject in need thereof an effective amount of one or more of the compositions described above. The diseases mentioned above also include their associated disorders.

The term "treating" or "treatment" used herein refers to administering one or more above-described compositions to a subject, who has a disease described above, a symptom of such a disease, or a predisposition toward such a disease, with the purpose to confer a therapeutic effect, e.g., to cure, relieve, alter, affect, ameliorate, or prevent the disease, the symptom of it, or the predisposition toward it.

The composition described above can be in form suitable for any route of administration. For example, when the composition is orally administered, the present invention in certain embodiments may be administered by any pharmaceutically acceptable oral dosage form including, solids (e.g., tablets, capsules), liquids (e.g., syrups, solutions and suspensions), orally dissolving dosage forms (e.g., orally disintegrating dosage forms, lozenges and troches), powders or granules.

The compositions may also be prepared for parenteral administration as a solution, or suspension. The compositions may also be in dry form ready for reconstitution (e.g., with the additional of sterile water for injection), prior to parenteral administration. Parenteral administration includes administration into any body space or tissue, for example intravenous, intra-arterial, intramuscular and subcutaneous. Where the intended cite of action is a solid tumor, in certain embodiments the composition may be injected directly into the tumor.

In certain other embodiments of the invention, one or more active compounds of the present invention are associated with a carrier substance such as a compound or molecule (e.g., an antibody), to facilitate the transport of the one or more active compounds to the intended cite of action. In certain preferred embodiments, active compound B (useful for treating a hyperproliferating tissue), is covalently bonded to an antibody that corresponds to a marker located on the hyperproliferative tissue. According to this aspect of the invention, it is contemplated that toxicity and adverse effects can be reduced because lower levels of the active agent are capable of providing the desired therapeutic effect relative to administration of the active agent that is not associated with a carrier substance.

The first, second, and third agents described above include active compounds, as well as any pharmaceutically acceptable derivatives such as their salts, pro-drugs, and solvates, if applicable. A salt, for example, can be formed between an anion and a positively charged group (e.g., amino) on an agent. Examples of suitable anions include chloride, bromide, iodide, sulfate, nitrate, phosphate, citrate, methanesulfonate, trifluoroacetate, acetate, chlorophenyoxyacetate, malate, tosylate, tartrate, fumarate, glutamate, glucuronate, lactate, glutarate, benzoate, embonate, glycolate, pamoate, aspartate, parachlorophenoxyisobutyrate, formate, succinate, cyclohexanecarboxylate, hexanoate, octonoate, decanoate, hexadecanoate, octodecanoate, benzenesulphonate, trimethoxybenzoate, paratoluenesulphonate, adamantanecarboxylate, glycoxylate, pyrrolidonecarboxylate, naphthalenesulphonate, 1-glucosephosphate, sulphite, dithionate, and maleate. Likewise, a salt can also be formed between a cation and a negatively charged group (e.g., carboxylate) on an agent. Examples of suitable cations include sodium ion, potassium ion, magnesium ion, calcium ion, and an ammonium cation such as tetramethylammonium ion. In certain embodiments, the agents also include salts containing quaternary nitrogen atoms. Examples of pro-drugs include esters and other pharmaceutically acceptable derivatives, which, upon administration to a subject, are capable of providing active compounds. A solvate refers to a complex formed between an active compound and a pharmaceutically acceptable solvent. Examples of pharmaceutically acceptable solvents include water, ethanol, isopropanol, ethyl acetate, acetic acid, and ethanolamine.

Other examples of the salts include arginine, L-arginine; DL-lysine; Bismuth Salicylate Basic; Bismuth salicylate; Magnesium; Diethylamine; sodium salt; imidazole; Sodium Aminosalicylate; Isoniazid Aminosalicylate; Physostigmine; Pregnenolone Acetylsalicylate; Choline Magnesium Trisalycylate (Trilisate); Zinc Oxide; Iodide; Acetic Acid Glacial Solution and Methyl.

Also within the scope of this invention is one or more compositions described above for use in treating a disease described herein, and the use of such a composition for the manufacture of a medicament for the treatment of a disease described herein.

All of the compounds mentioned above are known drugs and are readily available to the public. Some of the drugs can be purchased from chemical companies, such as Sigma-Aldrich, St. Louis, Mo. Where the drugs are not readily available, in certain embodiments, one of ordinary skill in art will appreciate that the compounds can be organically manufactured and identified according to accepted standards such as those found in the Merck Index, Remington's Pharmaceutical Sciences, USP/NF, and foreign publications. In certain embodiments, regimens for administering these drug compounds are well known and, if necessary, can be easily re-established by an ordinary skilled clinician. Effective doses will vary, as recognized by those skilled in the art, depending on the type or degree of the disease to be treated; the subject's size, weight, age, and sex; the route of administration; the excipient usage; rate of metabolism, rate of excretion, and the possible co-usage with other therapeutic treatment. In certain embodiments, coadministration of other drugs can lead to increased or decreased metabolism and or excretion requiring an adjustment in dose. In certain other embodiments, where one or more of the active agents are bound to plasma proteins, coadministration of other drugs that effect the extent of binding may also require an adjustment of dose. The daily dose of the compositions described above can be 5-10,000 mg (e.g., 10-5000 or 10-3,000 mg) of the first agent, 1-5,000 mg (e.g., 2-1,000 or 2-3,000 mg) of the second agent, and 0.1-1,000 mg (e.g., 1-50 mg) of the third agent.

In certain preferred embodiments the human dose of the composition of the present invention is about 5-5,000 mg of metformin, about 1-5,000 mg aspirin and about 0.1-1,000 mg serotonin creatinine complex. In certain more preferred embodiments, the human dose of the composition is about 1000 mg of metformin, about 400 mg aspirin and about 4 mg serotonin creatinine complex administered as multiple daily doses. In certain further preferred embodiments, this dose is administered three times a day.

One aspect of this invention features a method of administering an effective amount of one or more of the above-mentioned compositions to a subject for treating a disease described herein. Such a subject can be identified by a health care professional such as a clinician based on results from any suitable diagnostic method. "An effective amount" refers to the amount of one or more compositions described herein that is required to confer a therapeutic effect on a treated subject.

To practice the method of the present invention, in certain embodiments, one or more of the above-described compositions can be administered parenterally, orally, nasally, rectally, topically, or buccally. The term "parenteral" as used herein refers to subcutaneous, intracutaneous, intravenous, intramuscular, intraarticular, intraarterial, intrasynovial, intrasternal, intrathecal, intralesional, or intracranial injection, as well as any suitable infusion or injection technique.

A sterile injectable composition can be a solution or suspension in a non-toxic parenterally acceptable diluent or solvent, such as a solution in 1,3-butanediol. Examples of the acceptable vehicles and solvents that can be employed are mannitol, water, Ringer's solution, and isotonic sodium chloride solution. In addition, fixed oils are conventionally employed as a solvent or suspending medium (e.g., synthetic mono- or diglycerides). Fatty acid, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions.

These oil solutions or suspensions can also contain a long chain alcohol diluent or dispersant, carboxymethyl cellulose, or similar dispersing agents. Other commonly used surfactants such as Tweens or Spans or other similar emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms can also be used for the purpose of formulation.

A composition for oral administration can be any orally acceptable dosage form including capsules, tablets, emulsions and aqueous suspensions, dispersions, and solutions. In the case of tablets, commonly used carriers include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions or emulsions are administered orally, the active ingredient can be suspended or dissolved in an oily phase combined with emulsifying or suspending agents. If desired, certain sweetening, flavoring, or coloring agents can be added.

A nasal aerosol or inhalation composition can be prepared according to techniques well known in the art of pharmaceutical formulation. For example, such a composition can be prepared as a solution in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other solubilizing or dispersing agents known in the art.

A composition for topical administration can be prepared in form of an ointment, a gel, a plaster, an emulsion, a lotion, a foam, a cream of a mixed phase or amphiphilic emulsion system (oil/water-water/oil mixed phase), a liposome, a transfersome, a paste, or a powder.

Any of the compositions described above can also be administered in the form of suppositories for rectal administration. It also can be designed such that the composition is released in the intestine. For example, the composition is confined in a solid sub-unit or a capsule compartment that has respectively a matrix or a wall or a closure comprising an enteric polymer which dissolves or disperses at the pH of the small or large intestine to release the drug substance in the intestine. Suitable such polymers have been described above, for example with reference to U.S. Pat. No. 5,705,189.

In certain embodiments, the carrier in the pharmaceutical composition must be "acceptable" in the sense that it is compatible with the active ingredient of the composition (and preferably, capable of stabilizing the active ingredient) and not deleterious to the subject to be treated. One or more solubilizing agents can be utilized as pharmaceutical excipients for delivery of an active compound. Examples of other carriers include colloidal silicon oxide, magnesium stearate, cellulose, sodium lauryl sulfate, and D&C Yellow #10.

The term denotes malignant as well as nonmalignant cell populations. The excess cell proliferation can be determined by reference to the general population and/or by reference to a particular patient, e.g. at an earlier point in the patient's life. Hyperproliferative cell disorders can occur in different types of animals and in humans, and produce different physical manifestations depending upon the affected cells.

Hyperproliferative cell disorders include tumors as well as nontumors. A "tumor" here refers to an abnormal mass of tissue that results from excessive cell division that is uncontrolled and progressive, also called a neoplasm.

Examples of tumors include a variety of solid tumor such as laryngeal tumors, brain tumors, other tumors of the head and neck; colon, rectal and prostate tumors; breast and thoracic solid tumors; ovarian and uterine tumors; tumors of the esophagus, stomach, pancreas and liver; bladder and gall bladder tumors; skin tumors such as melanomas; and the like, and a fluid tumor such as leukemia.

A "solid tumor", as used herein, refers to an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign (not cancerous), or malignant (cancerous). Solid tumors have a distinct structure that mimics that of normal tissues and comprises two distinct but interdependent compartments: the parenchyma (neoplastic cells) and the stroma that the neoplastic cells induce and in which they are dispersed. Different types of solid tumors are named for the type of cells that form them. Examples of solid tumors are sarcomas, carcinomas, and lymphomas.

"Solid tumor" means a locus of tumor cells where the majority of the cells are tumor cells or tumor-associated cells.

More particularly, tumor here refers to either benign (not cancerous) or malignant tumors.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Cells can exist in different periods of a cell cycle such as: G1 phase cells, S phase cells, (indicating synthesis and doubling of DNA), and G2 phase cells. Comparing cancer cells to normal cells, one finds a decrease in the proportion of G1 phase cells in cancer, an increase in the proportion of cells in synthesis in cancer and an increase in the proportion of cells in G2 phase and S phase.

Example 1

In Example 1, B20L (Metformin 1 mM+aspirin 0.4 mM+serotonin creatinine sulfate complex 0.002 mM) and B20H (Metformin 10 mM+aspirin 4 mM+serotonin creatinine sulfate complex 0.02 mM) were tested to determine the effect on the cell cycle of pancreatic cancer cells after 24 hours. Each of the cell samples were then tested in a flow cytometer. The testing methodology and equipment used are set forth as follows. Cells were harvested and washed twice with phosphate buffered saline, (PBS) and fixed in 70% cold ethanol at 4.degree. C. overnight. Before analysis, cells were washed twice with PBS, containing 1% bovine serum albumin (BSA), then resuspended with 400 .mu.l PBS and treated with 100 .mu.g/ml RNase A (Roche Diagnostics) and 50 .mu.g/ml propidium iodide (PI) (Sigma). After incubation for 30 min at 37.degree. C., the cells were subjected to DNA content analysis. propidium iodide, (PI) fluorescence was analyzed with a FACS calibur flowcytometer, (Becton Dickinson). Data from at least 10,000 cells were analyzed with software. The results of a control group as well as the two active treatment groups are set forth in Table 1 below.

TABLE-US-00001 TABLE 1 Effect of B20L Metformin + aspirin + serotonin creatinine sulfate complex and B20H Metformin + aspirin + serotonin creatinine sulfate complex on Pancreatic Cancer Cells after 24 Hours Group G1 S G2 Control 63% 35.5% 1.5% B20L Metformin 87.30% 9.40% 3.30% 1 mM + aspirin 0.4 mM + serotonin creatinine sulfate complex 0.002 mM Metformin 10 mM + 88.70% 7.80% 3.40% aspirin 4 mM + serotonin creatinine sulfate complex 0.02 mM

The results indicate that Metformin+aspirin+serotonin creatinine sulfate complex can block pancreatic cancer cells in G1 phase from progressing into S phase and G2 phase after 24 hours as the two treatment groups have a higher proportion of cancer cells in the G1 phase.

Example 2

In Example 2, the testing procedure according to Example 1 above was carried out for 48 and 72 hours comparing the control group to a B20L treatment group. The results are provided in Table 2 below.

The results indicate that Metformin+aspirin+serotonin creatinine sulfate complex can block pancreatic cancer cells in G1 phase from progressing into S phase and G2 phase after 24, 48 and 72 hours as the two treatment groups have a higher proportion of cancer cells in the G1 phase.

Example 3

In Example 3, different dosages of Metformin+aspirin+serotonin creatinine sulfate complex were tested to determine the effect on the cell cycle of breast cancer cells after 24 hours. Each of the cell samples were then tested in a flow cytometer according to the procedures set forth in Example 1 above. The results of a control group as well as the two active treatment groups are set forth in Table 3 below.

TABLE-US-00003 TABLE 3 Effect of different dosages of Metformin + aspirin + serotonin creatinine sulfate complex on Breast Cancer Cells after 24 Hours Group G1 S G2 Control 43% 46.10% 10.6% (Metformin 1 mM + 59.60% 36.30% 4.10% aspirin 0.4 mM + serotonin creatinine sulfate complex 0.002 mM) Metformin 10 mM + 73.80% 20.00% 6.20% aspirin 4 mM + serotonin creatinine sulfate complex 0.02 mM

The results indicate that B20 different dosages of Metformin+aspirin+serotonin creatinine sulfate complex can block breast cancer cells in G1 phase from progressing into S phase cells after 24 hours as the two treatment groups have a lower proportion of cancer S phase cells.

Example 4

In Example 4, different dosages of Metformin+aspirin+serotonin creatinine sulfate complex were tested to determine the effect on proliferation speed of pancreatic cancer cells after 24, 48 and 72 hours. The testing methodology and equipment used are set forth as follows. Pancreatic cancer cells were subcultured into 96-well plates at approximately 4.times.10.sup.4 cells per ml and allowed to adhere for 24 h at 37.degree. C. before being treated with the drug. Cell viability was assessed using the Dojindo Cell Counting Kit-8. The cell viability was in direct proportion to the absorbance at 450 nm. Accordingly, the cell viability was expressed as the absorbance at 450 nm. All experiments were performed in triplicate on three separate occasions. The results of a control group as well as the two active treatment groups are set forth in Table 4 below.

TABLE-US-00004 TABLE 4 Effect of different dosages of Metformin + aspirin + serotonin creatinine sulfate complex on Proliferation Speed of Pancreatic Cancer Cells after 24, 48 and 72 Hours Group 24 H 48 H 72 H Control 0.40 .+-. 0.023 0.89 .+-. 0.053 1.805 .+-. 0.033 Metformin 1 0.335 .+-. 0.021* 0.725 .+-. 0.047** 0.787 .+-. 0.066** mM + aspirin 0.4 mM + serotonin creatinine sulfate complex 0.002 mM Metformin 10 0.296 .+-. 0.017** 0.491 .+-. 0.034** 0.565 .+-. 0.060** mM + aspirin 4 mM + serotonin creatinine sulfate complex 0.02 mM *p < 0.05, **p < 0.01

The procedures for performing this test were as follows. Hep G2 cells were prepared at 25*10.sup.6 cells/ml and 0.2 ml of the cell suspension (5*10.sup.6 cells) was injected in an exposed mouse mammary fat pad. When tumors achieved the required size (0.5 cm.sup.3), animals would be treated with 50 .mu.l of B10, dehydrated alcohol or 10% glucose solution once daily for 6 days. During 12 days after the last injection, tumor volume will be assessed by measuring tumor dimensions (long (L) and short (S)) and estimated it as V=0.52*L*S.sup.2. 12 days after the last injection, mice would be sacrificed and tumors would be dissected, weighed and stored in a formaline solution for further evaluation.).

The active drug group survival time was also better than control group indicating that this drug therapy can extend mice survival time and reduce cancer cell transplantation rate.

Example 12

In Example 12, the effect of B3 and B10 was tested to determine the effect on oncogenesis rate of hepatoma carcinoma H22 cells in KM mice. Fifty thousand (50,000) mice hepatoma carcinoma H22 cells were injected subcutaneously into KM mice. Treatment groups consisted of B3 and B10, administered three times a day for 30 days. After the drug was stopped, the mice were observed for the presence of tumor tissue to determine whether oncogenesis has occurred. The results of the B10 and B3 treatment groups and the G.S. group are set forth in Table 9 below.

TABLE-US-00012 TABLE 12 Oncogenesis Rate for Weeks 1, 2, 3, 4, 6 and 8 After Inoculation and Treatment with B10 (Metformin 50 mg/kg + aspirin 40 mg/kg + serotonin creatinine sulfate complex 0.4 mg/kg) and B3 (Metformin 50 mg/kg + celebrex 10 mg/kg + serotonin creatinine sulfate complex 0.4 mg/kg) Time after administration of drug and Oncogenesis Rate Group 1 w 2 w 3 w 4 w 6 w 8 w GS 60 70 70 80 90 90 Metformin 50 mg/kg + 10 20 20 20 20 20 aspirin40 mg/kg + serotonin creatinine sulfate complex 0.4 mg/kg Metformin 50 mg/kg + 30 50 50 50 50 50 celebrex 10 mg/kg + serotonin creatinine sulfate complex 0.4 mg/kg

The results indicate that 8 weeks after the drugs were administered, the Metformin 50 mg/kg+aspirin 40 mg/kg+serotonin creatinine sulfate complex 0.4 mg/kg group only had a 20% oncogenesis rate. The Metformin 50 mg/kg+celebrex 10 mg/kg+serotonin creatinine sulfate complex 0.4 mg/kg only had a 50% oncogenesis rate. Both active drug groups had a lower oncogenesis rate than the control group (90%). Therefore, these drugs can decrease the rate of transplantation of tumor cells.
