1-(4-Amino-phenyl)-pyrrolidin-3-yl-amine and 6-(3-amino-pyrrolidin-1-yl)-pyridin-3-yl-amine derivatives as melanin-concentrating hormone receptor-1 antagonists

Derivatives of 1-(4-amino-phenyl)-pyrrolidin-3-yl-amine and 6-(3-amino-pyrrolidin-1-yl)-pyridin-3-yl-amine were identified as potent and functionally active MCH-R1 antagonists. One compound with Ki = 2.3 nM demonstrated good oral bioavailability (32%) and in vivo efficacy in rats.

Derivatives of 1-(4-amino-phenyl)-pyrrolidin-3-yl-amine and 6-(3-amino-pyrrolidin-1-yl)-pyridin-3-yl-amine (I) were identified as potent and functionally active MCH receptor-1 (MCH-R1) antagonists. The compound 10 with Ki = 2.3 nM demonstrated good oral bioavailability (32%) and in vivo efficacy in rats.Figure optionsDownload as PowerPoint slide
