Cyanohydrin derivatives as enterovirus 71 (EV71) 3C protease (3C(pro)) inhibitors have been synthesized and assayed for their biochemical and antiviral activities. Compared with the reported inhibitors, cyanohydrins (1S,2S,2'S,5S)-16 and (1R,2S,2'S,5S)-16 exhibited significantly improved activity and attractive selectivity profiles against other proteases, which were a result of the specific interactions between the cyanohydrin moiety and the catalytic site of 3C(pro). Cyanohydrin as an anchoring group with high selectivity and excellent inhibitory activity represents a useful choice for cysteine protease inhibitors.
已合成氰醇衍生物作为肠道病毒71型(EV71)3C蛋白酶(3C(pro))抑制剂,并对其生化和抗病毒活性进行了测定。与已报道的抑制剂相比,氰醇(1S,2S,2'S,5S)-16和(1R,2S,2'S,5S)-16表现出显著提高的活性以及针对其他蛋白酶的良好选择性,这是氰醇部分与3C(pro)催化位点之间特异性相互作用的结果。氰醇作为具有高选择性和优异抑制活性的锚定基团,是半胱氨酸蛋白酶抑制剂的一个有用选择。
