The optimization of a series of fused β‐homophenylalanine inhibitors of dipeptidyl peptidase‐4 (DPP‐4) is described. Modification on the P2‐binding moiety of 6 (IC50 = 10 nM) led to the discovery of β‐homophenylalanine derivatives containing pyrrolidin‐2‐ylmethyl amides. The introduction of a sulfamine in the meta position of the phenyl ring improved the potency against DPP‐4 (6–12‐fold increase).
描述了二肽基肽酶-4 (DPP-4) 的一系列融合 β-高苯丙氨酸抑制剂的优化。对 6 的 P2 结合部分 (IC50 = 10 nM) 的修饰导致发现了含有吡咯烷-2-基甲基酰胺的 β-高苯丙氨酸衍生物。在苯环的间位引入磺胺提高了对抗 DPP-4 的效力(增加了 6-12 倍)。化合物 14k 显示出 DPP-4 抑制活性,IC50 值为 0.87 nM。同时,体内实验表明,14h 的疗效与剂量为 10 mg/kg 的西格列汀相当。
