ABSTRACT
A series of 2-aminobenzimidazole-based MCH1R antagonists was identified by core replacement of the aminoquinoline lead 1. Subsequent modification of the 2- and 5-positions led to improvement in potency and intrinsic clearance. Compound 25 exhibited good plasma and brain exposure, and attenuated MCH induced food intake at 30mg/kg PO in rats.
