The 3-hydroxyméthyl N-méthyl piperidine 4-chlorophenoxyacetate, hydrochloride, A, a potent anorectic, reduces weight gain of gold thioglucose obese mice through a reduced body fat and a decrease in metabolic efficiency. Compound A has much less effect in the lean mice than in the obese models. In
When chronically administered, 3-hydroxymethyl N-methyl piperidine (4-chlorophenoxy) acetate, hydrochloride, causes reduced food intake and weight gain in obese (fa/fa) rats. We observe an increase in free fatty acid concentration of obese (fa/fa) rats treated for 12 days.
The fruits of Piper retrofractum Vahl. have been used for their anti-flatulent, expectorant, antitussive, antifungal, and appetizing properties in traditional medicine, and they are reported to possess gastroprotective and cholesterol-lowering properties. However, their anti-obesity activity remains
In this paper, we report the discovery and the synthesis of novel, potential antipsychotic piperidine-2,6-dione derivatives combining potent dopamine D(2) , D(3) and serotonin 5-HT(1A) , 5-HT(2A) , 5-HT(2C) receptor properties. We describe the structure-activity relationships that led us to the
Cannabinoid CB(1) receptor antagonists exhibit pharmacologic properties favorable for the treatment of metabolic disease. CP-945,598 (1-[9-(4-chlorophenyl)-8-(2-chlorophenyl)-9H-purin-6-yl]-4-ethylamino piperidine-4-carboxylic acid amide hydrochloride) is a recently discovered selective, high
A new series of urea-based, 4-bicyclic heteroaryl-piperidine derivatives as potent SCD1 inhibitors is described. The structure-activity relationships focused on bicyclic heteroarenes and aminothiazole-urea portions are discussed. A trend of dose-dependent decrease in body weight gain in diet-induced
A series of (3R*,4R*)-3,4-dimethyl-4-(3-hydroxyphenyl)piperidine opioid antagonists with varying substituents on the nitrogen were evaluated for their effect on food consumption in obese Zucker rats. Opioid affinity (mu, kappa, and delta for selected compounds) and opioid antagonist activity (mu and
The peptide hormone ghrelin is the endogenous ligand for the type 1a growth hormone secretagogue receptor (GHS-R1a) and the only currently known circulating appetite stimulant. GHS-R1a antagonism has therefore been proposed as a potential approach for obesity treatment. More recently, ghrelin has
Agonists to opioid receptors induce a positive energy balance, whereas antagonists at these receptors reduce food intake and body weight in rodent models of obesity. An analog of 3,4-dimethyl-4-(3-hydroxyphenyl)piperidine, LY255582, is a potent non-morphinan antagonist for mu-, kappa-, and
N-Substituted trans-3,4-dimethyl-4-(3-hydroxyphenyl)piperidines are a class of pure opioid receptor antagonists with a novel pharmacophore. This opioid receptor antagonist pharmacophore was used as a lead structure to design and develop several interesting and useful opioid receptor antagonists. In
Hyperinsulinemia and exaggerated insulin response to glucose are among the hallmarks of obesity. However, the role of hyperinsulinemia in the etiology and maintenance of obesity has been controversial. If hyperinsulinemia plays a critical role as proposed, then its reversal may have therapeutic
Excessive uptake of fatty acids and glucose by adipose tissue triggers adipocyte dysfunction and infiltration of immune cells. Altered metabolic homeostasis in adipose tissue promotes insulin resistance, type 2 diabetes, hypertension, and cardiovascular disease. Inflammatory and metabolic processes
The discovery and synthesis of potential and novel antipsychotic coumarin derivatives, associated with potent dopamine D2, D3, and serotonin 5-HT1A and 5-HT2A receptor properties, are the focus of the present article. The most-promising derivative was
A substituted 4-aminopiperidine was identified as showing activity in an MCH assay from an HTS effort. Subsequent structural modification of the scaffold led to the identification of a number of active MCH antagonists. 3,5-Dimethoxy-N-(1-(naphthalen-2-ylmethyl)piperidin-4-yl)benzamide (5c) was among
A novel series of phenylthiazoles bearing cyclic amines at the phenyl-4 position was prepared with the objective of decreasing lipophilicity and improving the overall physicochemical properties and pharmacokinetic profile of the compounds. Briefly, the piperidine ring (compounds 10 and 12) provided
