Abstract

A new method for the preparation of elastase toxoid of Pseudomonas aeruginosa was developed. A chloroacetyl peptide derivative (CICH2CO-HOLeu-Ala-Gly-NH2; HOLeu, N-hydroxy-L-leucine), an active-site-directed irreversible inhibitor of Pseudomonas aeruginosa elastase, was used to prepare elastase toxoid with or without pretreatment with Formalin and L-lysine. Elastase toxoid thus obtained appeared to be ideal, possessing negligible enzyme activity while retaining full antigenicity and immunogenicity.

摘要

开发了一种制备铜绿假单胞菌弹性蛋白酶类毒素的新方法。氯乙酰肽衍生物(CICH2CO-HOLeu-Ala-Gly-NH2;HOLeu,N-羟基-L-亮氨酸),一种铜绿假单胞菌弹性蛋白酶的活性位点定向不可逆抑制剂,用于制备经或未经福尔马林和L-赖氨酸预处理的弹性蛋白酶类毒素。由此获得的弹性蛋白酶类毒素似乎很理想,酶活性可忽略不计,同时保留了完整的抗原性和免疫原性。
