obtained compounds were assayed as inhibitors of the Clostridium histolyticum collagenase, ChC (EC 3.4.24.3), a zinc enzyme which degrades triple helical collagen. The hydroxamate derivatives were generally 100-500 times more active than the corresponding carboxylates. In the series of synthesized derivatives, substitution patterns leading to best ChC inhibitors were those involving perfluoroalkylsulfonyl-
磺酰化的L-缬氨酸异羟肟酸酯衍生物是通过使烷基/芳基磺酰基卤化物与标题氨基酸反应,然后用苄基氯处理并将COOH部分转化为CONHOH基团而获得的。通过N-苄基-L-缬氨酸与芳基异氰酸酯,芳基磺酰基异氰酸酯或苯甲酰基异硫氰酸酯反应,然后在碳二亚胺存在下,将COOH与羟胺类似地转化为CONHOH部分,从而获得其他衍生物。测定获得的化合物作为解组织梭状芽孢杆菌胶原酶ChC(EC 3.4.24.3)的抑制剂,ChC是降解三重螺旋胶原的锌酶。异羟肟酸酯衍生物的活性通常比相应的羧酸盐高100-500倍。在一系列合成衍生物中,导致最佳ChC抑制剂的取代模式是涉及全氟烷基磺酰基和取代芳基磺酰基部分的取代基,例如五氟苯基磺酰基;3-和4-保护的氨基苯基磺酰基-; 3-和4-羧苯基磺酰基-; 3-三氟甲基苯基磺酰基;或1-和2-萘基等。与基质金属蛋白酶异羟肟酸酯抑制剂相似,此处报道的ChC抑制剂必须在P(2'
