Genetic manipulation studies in mice at both the MCH receptor 1 (MCHR1) as well as the MCH peptide levels have implicated MCHR1 as a key player in energy homeostasis. The phenotype exhibited by these studies, that is, increased metabolic rate, resistance to high fat diet, and subsequent weight loss, has spurred considerable efforts to develop antagonists of MCHR1. In continuation of efforts directed toward this goal, the present work capitalizes on the putative binding mode of an MCH antagonist, resulting in the identification of several novel chemotypes that are potent and selective MCHR1 antagonists. In addition, the favorable pharmacokinetics of representative examples has allowed for the evaluation of an MCHR1 antagonist in a high fat diet-induced obese rodent model of obesity. The tolerability of the right-hand side of the template for diverse chemotypes accompanied by favorable effects on weight loss enhances the attractiveness of this template in the pursuit toward development of effective anti-obesity agents.

[EN] This invention relates to novel heterocycles which are antagonists at the melanin-concentrating hormone receptor 1 (MCHR1), also referred to as 11CBy, to pharmaceutical compositions containing them, to processes for their preparation, and to their use in medicines. Compounds of the invention have formula (I). [FR] L'invention concerne des dérivés de benzopyrane substitués, des stéréoisomères et des sels pharmaceutiquement acceptables desdits composés, ainsi que des procédés appropriés pour les préparer. Les composés de la présente invention s'utilisent comme agonistes du récepteur beta des oestrogènes. De tels agonistes s'utilisent dans le traitement d'affections induites par le récepteur beta des oestrogènes, telles que le cancer de la prostate ou l'hyperplasie prostatique bénigne (HPB).
