  Synthesis, Structure–Activity Relationship, and Pharmacological Studies of Novel Melanin-Concentrating Hormone Receptor 1 Antagonists 3-Aminomethylquinolines: Reducing Human Ether-a-go-go-Related Gene (hERG) Associated Liabilities

  摘要：

  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.

  摘要：

  通过三种合成途径制备了一系列在1位带有一个联苯基甲基的取代的2-丁基苯并咪唑，并评估了其在体外和体内的血管紧张素II（AII）受体拮抗活性。使用牛肾上腺皮质膜测定结合亲和力。相对于未取代化合物（13a）的亲和力，在4-，5-或6-位的取代降低了亲和力。但是，大多数在7位带有取代基的化合物的结合亲和力与DuP 753（氯沙坦）相当。在功能研究中，发现羧基对于对抗AII的拮抗活性非常重要。2-丁基-1-[[[2'-（1H-四唑-5-基）联苯-4-基]甲基] -1H-苯并咪唑-4-，-5-，-6-的比较 AII诱导的兔主动脉环收缩试验中的-7和羧酸（15a-d）清楚地证明了羧基取代位置的重要性。在体内试验中，苯并咪唑-7-羧酸的口服给药对大鼠的AII诱导的升压反应产生了长期抑制作用。发现苯并咪唑环的7位上的最佳取代基是羧基或酯基。代表性化合物2-丁基-1-[[[2'-（1H-四唑-5-基）联苯-4-基]甲基]

  A series of substituted 2-butylbenzimidazoles bearing a biphenylylmethyl moiety at the 1-position was prepared via three synthetic routes and evaluated for angiotensin II (AII) receptor antagonistic activity (in vitro and in vivo). Binding affinity was determined using bovine adrenal cortical membrane. Substitution at the 4-, 5-, or 6-position reduced the affinity relative to that of the unsubstituted
