Dipeptidyl nitroalkenes are potent reversible inhibitors of cysteine proteases. Inhibitor resulted to be the most potent one with values of 0.49 and 0.44 nM against rhodesain and cruzain, respectively. According to enzymatic dilution and dialysis experiments, as well as computational and NMR studies, dipeptidyl nitroalkenes are tightly binding covalent reversible inhibitors.
二肽基硝基烯烃是半胱氨酸蛋白酶的强效可逆抑制剂。抑制剂被证明是最有效的,对罗得西亚锥虫蛋白酶和克氏锥虫蛋白酶的抑制常数分别为0.49和0.44纳摩尔。根据酶稀释和透析实验以及计算和核磁共振研究,二肽基硝基烯烃是紧密结合的共价可逆抑制剂。
