subtype 5 (SSTR5) antagonists. Four optimized compounds each representing a subseries showed improvement in their metabolic stability and pharmacokinetic profiles compared to those of the original lead compound 1 while maintaining pharmacodynamic efficacy. The optimized cyclopropyl analogue 13 demonstrated efficacy in a mouse oral glucose tolerance test and an improved metabolic profile and pharmacokinetic
设计并合成了一系列结构多样的氮杂螺杂十二烷酮和螺恶唑烷酮类似物,作为有效的和选择性的生长抑素受体亚型5(SSTR5)拮抗剂。与原始先导化合物1相比,每种代表一个亚系列的四种优化化合物均表现出其代谢稳定性和药代动力学方面的改善,同时保持了药效学功效。在恒河猴研究中,优化的环丙基类似物13在小鼠口服葡萄糖耐量试验中显示出功效,并改善了代谢特性和药代动力学特性。在本交流中,我们讨论了结构,体外和体内活性,代谢稳定性之间的关系,以及这些化合物最终作为治疗2型糖尿病的治疗剂的潜力。此外,
