2-Aminoquinoline melanin-concentrating hormone (MCH)1R antagonists

A series of 2-aminoquinoline compounds was prepared and evaluated in MCH1R binding and functional antagonist assays. Small dialkyl, methylalkyl, methylcycloalkyl, and cyclic amines were tolerated at the quinoline 2-position. The in vivo efficacy of compound 12 was explored and compared to that of a related inactive analog to determine their effects on food intake and body weight in rodents.

Structure–activity relationships and in vivo activity of 2-aminoquinoline MCH1R antagonists are reported.Figure optionsDownload as PowerPoint slide
