peptidase IV (DPP-IV) inhibitors are expected to become a new type of antidiabetic drugs. Most known DPP-IV inhibitors often resemble the dipeptide cleavage products, with a proline mimic at the P1 site. As off-target inhibitions of DPP8 and/or DPP9 have shown profound toxicities in the in vivo studies, it is important to develop selective DPP-IV inhibitors for clinical usage. To achieve this, a new class
二肽基肽酶IV(DPP-IV)抑制剂有望成为新型的抗糖尿病药物。大多数已知的DPP-IV抑制剂通常类似于二肽裂解产物,脯氨酸模拟物位于P1位点。由于DPP8和/或DPP9的脱靶抑制作用在体内研究中显示出深远的毒性,因此开发用于临床的选择性DPP-IV抑制剂很重要。为此,合成了新型的基于2- [3-[[2-[(2S)-2-氰基-1-吡咯烷基] -2-氧乙基]氨基] -1-氧丙基]的DPP-IV抑制剂。 。SAR研究产生了许多DPP-IV抑制剂,其IC(50)值<50 nM,对DPP8(IC(50)> 100 microM)和DPP-II(IC(50)> 30 microM)具有优异的选择性。 。在Wistar大鼠中口服葡萄糖激发后,化合物21a抑制了血糖升高,并且在BALB / c小鼠中抑制了血浆DPP-IV活性长达4小时。结果表明,化合物21a具有与NVP-LAF237(4)相当的体外和体内活性,该活性正在临床研究中。
