Abstract :
The optimization of a series of 4-(dimethylamino)quinazoline antagonists of the melanin-concentrating hormone receptor 1 (MCH-R1) is described. The combination of the elaboration of both the linker portion and the terminal phenyl ring provided N-(cis-4-{[4-(dimethylamino)quinazolin-2-yl]amino}cyclohexyl)-3,4-difluorobenzamide hydrochloride 28 (ATC0175), which showed excellent antagonist activity at the MCH-R1 (IC50 = 3.4 nM) as well as good selectivity over the Y5 and the α2A receptors.
