Dipeptidyl peptidase IV (DPP-IV) inhibitors are promising antidiabetic drugs, and several drugs are in the developmental stage. We previously reported that the introduction of fluorine to the 4-position of 2-cyanopyrrolidine enhanced the DPP-IV inhibitory effect. In the present report, we examined the structure-activity relationship (SAR) of 2-cyano-4-fluoropyrrolidine with N-substituted glycine at
二肽基肽酶IV(DPP-IV)抑制剂是有前途的抗糖尿病药物,并且几种药物都处于开发阶段。我们先前曾报道,将氟引入2-氰基吡咯烷的4-位可增强DPP-IV的抑制作用。在本报告中,我们研究了2-氰基-4-氟吡咯烷与1位上的N-取代甘氨酸的结构-活性关系(SAR)。我们报告鉴定出具有长期持续的血浆药物浓度和有效的降血糖活性的有效和稳定的DPP-IV抑制剂(TS-021)。
