Certain amino-acid derivatives are disclosed as effective inhibitors of human leukocyte elastase and therefore useful in preventing the imbalance of this proteolytic enzyme in vivo. The compounds specifically are derivatives L-valine, L-norvaline, L-norleucine, and L-methionine methyl ester azolides succinimides or pyridones and sulfonate salts, and related compounds such as L-leucine and L-phenylalanine methyl ester derivatives. The compounds were found to be excellent inhibitors in that they embody both inhibitory and anti-oxidant or anti-inflammatory activity.
某些氨基酸衍生物被披露为有效的人类白细胞弹性蛋白酶抑制剂,因此在预防体内这种蛋白酶的失衡方面非常有用。这些化合物具体是L-缬氨酸衍生物、L-正异戊氨酸衍生物、L-正壬氨酸衍生物和L-甲硫氨酸甲酯唑啉酰亚胺或吡啶酮和磺酸盐等相关化合物,以及L-亮氨酸和L-苯丙氨酸甲酯衍生物。这些化合物被发现是优秀的抑制剂,因为它们具有抑制和抗氧化或抗炎活性。
