A novel series of pyrrolidine-2-carbonitrile and 4-fluoropyrrolidine-2-carbonitrile derivatives was designed, synthesized, and found to act as dipeptidyl peptidase-4 (DPP-4) inhibitors. From this series of compounds, compound 17a was identified as an efficacious, safe, and selective inhibitor of DPP-4. In vivo studies in ICR and KKAy mice showed that administration of this compound resulted in decreased
设计,合成了一系列新颖的吡咯烷-2-甲腈和4-氟吡咯烷-2-甲腈衍生物,并发现它们可作为二肽基肽酶-4(DPP-4)抑制剂。从这一系列化合物中,化合物17a被鉴定为DPP-4的有效,安全和选择性抑制剂。在ICR和KKAy小鼠中进行的体内研究表明,口服葡萄糖激发后,给予这种化合物可导致这些小鼠血糖降低。化合物17a显示出高的DPP-4抑制活性(IC 50 = 0.017μM),对DPP-4的中等选择性(选择性比:DPP-8 / DPP-4 = 1324; DPP-9 / DPP-4 = 1164),并且在ICR和KKAy小鼠的口服葡萄糖耐量试验中有良好的疗效。这些体内抗糖尿病特性及其在Sprague-Dawley大鼠中理想的药代动力学特征表明,化合物17a是有望作为抗糖尿病药开发的候选药物。
