Discovery of novel, orally available benzimidazoles as melanin concentrating hormone receptor 1 (MCHR1) antagonists
摘要:
Melanin concentrating hormone (MCH) is an important mediator of energy homeostasis and plays role in several disorders such as obesity, stress, depression and anxiety. The synthesis and biological evaluation of novel benzimidazole derivatives as MCHR1 antagonists are described. The in vivo proof of principle for weight loss with a lead compound from this series is exemplified. (c) 2010 Elsevier Ltd. All rights reserved.

also exerts a beneficial effect in the condensation of N-monobenzylated o-phenylenediamines with aldehydes. The water-assisted C–N bond formation chemistry led to metal/base-free synthesis of N-monobenzylated o-nitroanilines and N-monobenzylated o-phenylenediamines. The indispensable/advantageous role of water in the various stage of the N-alkylation–reduction–condensation process exemplifies an ‘all-water’
