the parasitic cysteineproteases rhodesain, cruzain and falcipain-2 related to sleeping sickness, Chagas disease and malaria, respectively. They have also been tested against human cathepsins B and L1 for selectivity. Dipeptidyl enoates resulted to be irreversibleinhibitors of these enzymes. Some of the members of the family are very potent inhibitors of parasitic cysteineproteases displaying k2nd
已经制备了二肽烯醇酯家族,并针对与睡眠病,恰加斯病和疟疾有关的寄生性半胱氨酸蛋白酶罗氏蛋白酶,克鲁萨因和falcipain-2进行了测试。还针对人组织蛋白酶B和L1对它们进行了选择性测试。二肽烯醇酸酯是这些酶的不可逆抑制剂。该家族中的某些成员是非常有效的寄生半胱氨酸蛋白酶抑制剂,显示出7个数量级的k 2nd(M -1 s -1)值。还进行了体内抗原生动物测试。抑制剂对恶性疟原虫,布鲁氏锥虫,克鲁氏锥虫的微摩尔范围显示IC 50值甚至对利什曼原虫(Leishmania donovanii)的价值更低。
