were found to inhibit irreversibly both enzymes. Compound 10 was found to be a specific and selective inhibitor of human leukocyte elastase. In contrast to these, inhibitors derived from glycine methyl ester 1, D-valine methyl ester 4, and D-norvaline methyl ester 6 were found to be inactive. The results of the present study show that latent isocyanates derived from appropriate amino acids can serve as
已经合成了几种氨基酸衍生的偶氮内酯(I),并研究了它们对人白细胞弹性蛋白酶和猪胰弹性蛋白酶的抑制活性。发现抑制活性取决于前体氨基酸酯的性质。因此,发现衍生自L-缬氨酸甲酯3,L-正缬氨酸甲酯5,DL-正亮氨酸甲酯9和L-甲硫氨酸甲酯10的化合物不可逆地抑制两种酶。发现化合物10是人白细胞弹性蛋白酶的特异性和选择性抑制剂。与这些相反,发现衍生自甘氨酸甲酯1,D-缬氨酸甲酯4和D-去甲缬氨酸甲酯6的抑制剂是无活性的。
