discovery. Recent studies have shown that allosteric modulation of serotonin 2C receptor (5-HT2C) as a viable strategy for the treatment of various central nervous system (CNS) disorders. Considering the critical role of 5-HT2C in the modulation of appetite, a selective positive allosteric modulator (PAM) of 5-HT2C offers a new opportunity for anti-obesity therapeutic development. In this study, phenyl cyclopropyl-linked
最近,在药物发现中,G蛋白偶联受体的变构调节剂获得了显着的发展。最近的研究表明,血清素2C受体(5-HT 2C)的变构调节是治疗各种中枢神经系统(CNS)疾病的可行策略。考虑到5-HT的关键作用2C食欲的调节,5-HT的选择性正变构调节剂(PAM)2C提供了抗肥胖治疗发展的新契机。在这项研究中,合成了苯基环丙基连接的N-杂环并在5-HT 2C评估了其激动剂和PAM活性。我们的研究表明,咪唑连接的苯基环丙基甲酮对5-HT均具有PAM活性2C和血清素2B受体(5-HT 2B)。有趣的是,哌嗪连接的苯基环丙基甲酮(58)作为5-HT 2C的PAM有活性(将5-HT的E max增加至139%),并且作为5-HT 2B的负变构调节剂(NAM)有活性(降低EC 50 5-HT 10倍,而不会影响E max)。合成正构激动剂氯酪蛋白对5-HT 2B的作用与化合物58相似。分子对接研究表明,所有活性化合物均与5-HT
