  Melanin-Concentrating Hormone Receptor 1 Antagonists. Synthesis and Structure–Activity Relationships of Novel 3-(Aminomethyl)quinolines

  摘要：

  It was found that 3-(aminomethyl)quinoline derivatives showed high binding affinities for melanin-concentrating hormone receptor 1 (MCHR1) with reduced affinity for serotonin receptor 2c (5-HT2c) when the dihydronaphthalene nucleus of compound 1 (human MCHR1, IC50 = 1.9 nM; human 5-HT2c receptor, IC50 = 0.53 nM) was replaced by other bicyclic core scaffolds. Among the synthesized compounds, 8-methylquinoline derivative 5v especially showed high binding affinity (IC50 = 0.54 nM), potent in vitro antagonistic activity (IC50 = 2.8 nM) for MCHR1, and negligible affinity for 5-HT2c receptor (IC50 > 1000 nM). Oral administration of 5v significantly and dose-dependently suppressed nocturnal food intake in diet-induced obese rats and did not affect food intake in MCHR1-deficient mice. These results and rat pharmacokinetic study findings suggested that compound 5v is a highly potent, orally bioavailable, and centrally acting nonpeptide MCHR1 antagonist.

  Recently, we discovered 3-aminomethylquinoline derivative 1, a selective, highly potent, centrally acting, and orally bioavailable human MCH receptor 1 (hMCHR1) antagonist, that inhibited food intake in F344 rats with diet-induced obesity (DIO). Subsequent investigation of 1 was discontinued because 1 showed potent hERG K+ channel inhibition in a patch-clamp study. To decrease hERG K+ channel inhibition, experiments with ligand-based drug designs based on 1 and a docking study were conducted. Replacement of the terminal p-fluorophenyl group with a cyclopropylmethoxy group, methyl group introduction on the benzylic carbon at the 3-position of the quinoline core, and employment of a [2-(acetylamino)ethyl]amino group as the amine portion eliminated hERG K+ channel inhibitory activity in a patch-clamp study, leading to the discovery of N-3-[(1R)-1-[2-(acetylamino)ethyl]amino}ethyl]-8-methylquinolin-7-yl}-4-(cyclopropylmethoxy)benzamide (R)-10h. The compound (R)-10h showed potent inhibitory activity against hMCHR1 and dose-dependently suppressed food intake in a 2-day study on DIO-F344 rats. Furthermore, practical chiral synthesis of (R)-10h was performed to determine the molecule's absolute configuration.
