Aza-peptide epoxides, a new class of irreversible protease inhibitors, are specific for the clan CD cysteine proteases. The inhibitors have second-order rate constants up to 10(5) M(-1) s(-1), with the most potent epoxides having the S,S stereochemistry. The aza-Asn derivatives are effective legumain inhibitors, while the aza-Asp epoxides were specific for caspases. The inhibitors have little or no inhibition
氮杂肽环氧化物是一类新的不可逆的蛋白酶抑制剂,对氏族CD半胱氨酸蛋白酶具有特异性。抑制剂具有高达10(5)M(-1)s(-1)的二阶速率常数,最有效的环氧化物具有S,S立体化学。氮杂-Asn衍生物是有效的豆蔻蛋白酶抑制剂,而氮杂-Asp环氧化物对胱天蛋白酶具有特异性。抑制剂对其他蛋白酶(如胰凝乳蛋白酶,木瓜蛋白酶或组织蛋白酶B)几乎没有抑制作用。
