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.

The synthesis and SAR of tetrahydrocarboline analogs as MCH-1 antagonists are described.Figure optionsDownload as PowerPoint slide
