various cysteine cathepsins with endopeptidase activity, of two new families of hitherto unknown 1,3,5-triazines, substituted by a nitrile function and either a cyclohexylamine moiety (5-like) or a piperazine moiety (9-like) are described. The structure-activity relationship was discussed; from 16 synthesized novel compounds, 9h was the most active and selectively inhibitor of Cat K (IC50 = 28 nM) and Cat
对各种半胱氨酸组织蛋白酶与内肽酶活性,两个新的家庭的合成和评价迄今未知的1,3,5-三嗪,由腈官能团以及一个环己基部分(取代的5 -样)或哌嗪部分(9样)进行了说明。讨论了结构-活性关系;从16种合成的新化合物中,9h是Cat K(IC 50 = 28 nM)和Cat S(IC 50 = 23 nM)最具活性和选择性的抑制剂。组织蛋白酶K和S的9h与X射线晶体结构的分子对接证实了与Cys25具有关键共价键的共同结合模式。我们观察到9H是对三氟苯基位于S2口袋中,并与Tyr67和Met68具有疏水相互作用。三嗪和哌嗪部分位于S'1口袋中,并与Gly23,Cys63,Gly64和Gly65相互作用。总而言之,这些结果表明,新的类似物可以使它们成为对抗某些病毒的有效试剂,这些病毒的糖蛋白裂解是由一系列蛋白酶介导的。
