摘要
寄生虫是包括原虫、吸虫、绦虫、线虫、棘头虫等在内的一大类生物的总称,可引起重要的人畜寄生虫病。抗寄生虫药物的长期使用甚至是滥用使得寄生虫对现有药物产生了明显的抗药性,急需开发新型药物以有效控制寄生虫感染。乳酸脱氢酶(lactate dehydrogenase,LDH)是糖酵解途径的末端酶,在还原型辅酶Ⅰ(NADH)和氧化型辅酶Ⅰ(NAD+)的辅助下,催化丙酮酸与乳酸之间的可逆反应,释放能量供寄生虫所需。本文针对抗寄生虫药物靶标的鉴定方法以及寄生虫LDH作为潜在药物靶标的研究进展进行了综述,对阐明药物的分子作用机理及研发新药具有重要的理论意义。
Parasites include protozoon, trematodes, cestodes, nematode, acanthocephalan and so on, which cause diseases in human beings and animals. The misuse of antihelmintics has led to wide and serious drug-resistance. Therefore, there is an extremely urgent need for development of new drugs. Lactate dehydrogenase(LDH) acts as the terminal enzyme on glycolytic pathway and catalyzes the reversible reaction of pyruvate to lactate. In the process of this metabolic pathway, NADH and NAD+ serve as coenzymes thus the energy resources are generated for parasites. This article summarizes the methods used in studying antiparasitic drug targets and progress in research on LDH as a potential drug target for parasites, representing important theoretical significance in the research on the molecular mechanisms of drugs and development of new drugs.
