A series of (5-substituted pyrrolidinyl-2-carbonyl)-2-cyanopyrrolidine (C5-Pro-Pro) analogues was discovered as dipeptidyl peptidase IV (DPPIV) inhibitors as a potential treatment of diabetes and obesity. X-ray crystallography data show that these inhibitors bind to the catalytic site of DPPIV with the cyano group forming a covalent bond with the serine residue of DPPIV. The C5-substituents make various
发现了一系列(5-取代的吡咯烷基-2-羰基)-2-氰基吡咯烷(C5-Pro-Pro)类似物作为二肽基肽酶IV(DPPIV)抑制剂,可用于治疗糖尿病和肥胖症。X射线晶体学数据表明,这些抑制剂与DPPIV的催化位点结合,其中氰基与DPPIV的丝氨酸残基形成共价键。C5取代基与酶发生各种相互作用,并影响抑制剂的效能,化学稳定性,选择性和PK特性。优化的类似物对亚纳摩尔的K(i)具有极强的效力,化学性质稳定,在血浆存在下几乎没有效力降低,并且对相关肽酶的选择性超过1,000倍。
