Synthesis and SAR of 4-aryl-1-(indazol-5-yl)pyridin-2(1H)ones as MCH-1 antagonists for the treatment of obesity.

A new series of 4-aryl-1-(indazol-5-yl)pyridin-2(1H)ones possessing MCH-1 receptor antagonism is presented. Suzuki coupling of boronic acids with key triflate 6 allowed rapid generation of a range of analogs. The SAR of the MCH-1 receptor was explored with a variety of aryl and heterocyclic moieties. Selected compounds were studied in a five-day diet induced obese mouse model to evaluate their potential use as weight loss agents.

Tetrahydrocarboline analogs as MCH-1 antagonists

A new series of tetrahydrocarbolines with potent MCH-1 antagonist activity were synthesized, using a conformationally constrained design approach towards optimizing pharmacokinetic properties. Two compounds from this series were progressed to a 5-day diet-induced obesity mouse screening model to evaluate their potential as weight loss agents. Both compounds produced a highly significant reduction in weight, which was attributed to their improved pharmacokinetic profile.
