dipeptidyl peptidase II (DPP II) inhibitors. gamma-Amino substitution with arylalkyl groups, for example, a 2-chlorobenzyl moiety, resulted in a DPP II inhibitor with an IC(50) = 0.23 nM and a high selectivity toward DPP IV (IC(50) = 345 microM). Furthermore, it was shown that the basicity of the gamma-amino is important and that alpha-amino substitution is not favorable. Piperidine-2-nitriles did not
使用1-[(S)-2,4-二氨基丁酰基]哌啶作为先导化合物,我们开发了一系列高效的选择性二肽基肽酶II(DPP II)抑制剂。用芳基烷基(例如2-氯苄基部分)进行γ-氨基取代,得到DPP II抑制剂,其IC(50)= 0.23 nM,对DPP IV的选择性高(IC(50)= 345 microM)。此外,已表明γ-氨基的碱性是重要的,而α-氨基取代是不利的。哌啶-2-腈没有显示出效力的增加,而是降低了选择性。在哌啶上引入4-甲基或3-氟提高了选择性并保留了高效能。
