Characterization of a novel, brain-penetrating CB1 receptor inverse agonist: metabolic profile in diet-induced obese models and aspects of central activity.

Pharmacologic antagonism of cannabinoid 1 receptors (CB1 receptors) in the central nervous system (CNS) suppresses food intake, promotes weight loss, and improves the metabolic profile. Since the CB1 receptor is expressed both in the CNS and in peripheral tissues, therapeutic value may be gained with CB1 receptor inverse agonists acting on receptors in both domains. The present report examines the metabolic and CNS actions of a novel CB1 receptor inverse agonist, compound 64, a 1,5,6-trisubstituted pyrazolopyrimidinone.

Cevoglitazar, a novel peroxisome proliferator-activated receptor-alpha/gamma dual agonist, potently reduces food intake and body weight in obese mice and cynomolgus monkeys.

Cevoglitazar is a dual agonist for the peroxisome proliferator-activated receptor (PPAR)-alpha and -gamma subtypes. Dual activation of PPARalpha and -gamma is a therapeutic approach in development for the treatment of type 2 diabetes mellitus and diabetic dyslipidemia. In this report, we show that, in addition to improving insulin sensitivity and lipid metabolism like other dual PPAR agonists, cevoglitazar also elicits beneficial effects on energy homeostasis in two animal models of obesity.

Perhydroquinolylbenzamides as novel inhibitors of 11beta-hydroxysteroid dehydrogenase type 1.

High-throughput screening identified 5 as a weak inhibitor of 11beta-HSD1. Optimization of the structure led to a series of perhydroquinolylbenzamides, some with low nanomolar inhibitory potency. A tertiary benzamide is required for biological activity and substitution of the terminal benzamide with either electron-donating or -withdrawing groups is tolerated.

A quantitative assay for the non-covalent association between apolipoprotein[a] and apolipoprotein B: an alternative measure of Lp[a] assembly.

Increasing evidence suggests that the assembly of lipoprotein[a] (Lp[a]) proceeds in two steps. In the first step, non-covalent interactions between apolipoprotein[a] (apo[a]) and apolipoprotein B (apoB) of low density lipoprotein (LDL) form a dissociable apo[a]:LDL complex. In the second step, a covalent disulfide linkage forms the stable Lp[a] particle.

Antihypertensive and natriuretic effects of CGS 30440, a dual inhibitor of angiotensin-converting enzyme and neutral endopeptidase 24.11.

Dual angiotensin-converting enzyme (ACE)/neutral endopeptidase (NEP) inhibitors, by decreasing angiotensin-II production and by preventing the degradation of atrial natriuretic peptide (ANP), may be useful for the treatment of hypertension and congestive heart failure. The thiol dipeptide CGS 30440 (prodrug of CGS 30008, IC50: ACE/NEP = 19/2 nM) administered to rats (10 mg/kg p.o.
