We studied synthetic modifications of N-mercaptoacylamino acid derivatives to develop a new class of leukotriene A4 (LTA4) hydrolase inhibitors. S-(4-Dimethylamino)benzyl-l-cysteine derivative 2a (SA6541) showed inhibitory activity against LTA4 hydrolase (IC50, 270 nM) and selectivity over other metallopeptidases except angiotensin-converting enzyme (ACE, IC50, 520 nM). Modification at the para-substituent
我们研究了N-巯基酰基氨基酸衍生物的合成修饰,以开发一类新的白三烯A 4(LTA 4)水解酶抑制剂。小号- (4-二甲基氨基)苄基-升-半胱氨酸衍生物2A(SA6541)显示针对LTA抑制活性4水解酶(IC 50,270 nm)的和选择性优于其它金属肽除了血管紧张素转换酶(ACE,IC 50,520 nm)的。化合物2a苯环的对位取代基上的修饰改进了LTA 4水解酶抑制活性以及对ACE的选择性。最后,我们获得了作为有效的和选择性的LTA 4水解酶抑制剂的S-(4-环己基)苯并-1-半胱氨酸衍生物11l和16i。
