In this paper, the synthesis and structure-activity relationships (SAR) of two classes of electrophile-based dipeptidyl peptidase IV (DPP IV) inhibitors, the ketopyrrolidines and ketoazetidines, is discussed. The SAR of these series demonstrate that the 2-thiazole, 2-benzothiazole, and 2-pyridylketones are optimal S1' binding groups for potency against DPP IV. In addition, both cyclohexyl glycine (CHG)
在本文中,讨论了两类基于亲电子试剂的二肽基肽酶IV(DPP IV)抑制剂,酮吡咯烷和酮氮杂环丁烷的合成和构效关系(SAR)。这些系列的SAR表明,2-噻唑,2-苯并噻唑和2-吡啶基酮是针对DPP IV效力的最佳S1'结合基团。此外,环己基甘氨酸(CHG)和八氢吲哚羧酸酯(OIC)均是每个系列中最有效的S2结合基团。在中心环的α位的立体化学与酮吡咯烷系列中的效力有关,但与酮氮杂环丁烷系列中的效力无关。最后,酮氮杂环丁烷比相应的酮吡咯烷烷显示出增强的稳定性,同时保持它们的效力。实际上,
