在所有革兰氏阳性和无氧呼吸的革兰氏阴性细菌中,甲基萘醌在电子传递和ATP生成中是必不可少的。通过抑制目标生物中甲基萘醌的产生,无论生物的生长阶段如何,都可以达到杀菌作用。这一途径在人类细胞中是不存在的,因为甲基萘醌只能通过饮食获得。本文提供了主要进展的简要回顾,目前,在所有的生物合成途径的酶的步骤甲基萘醌。评估结构-活性关系,以及将这些关系转化为生长抑制研究的结果。在所有革兰氏阳性和无氧呼吸的革兰氏阴性细菌中,甲基萘醌在电子传递和ATP生成中是必不可少的。在生物合成途径的不同步骤抑制甲基萘醌的生产显示出有希望的新型抗菌作用。
Menaquinone is essential in electron transport and ATP generation in all Gram-positive, and anaerobically respiring Gram-negative bacteria. By inhibiting menaquinone production in target organisms, bactericidal action can be achieved irrespective of the organisms' growth phase. This pathway is absent in human cells, as menaquinone is obtained only through the diet. This paper provides a succinct review of major advancements, where present, at all enzymatic steps of the biosynthetic pathway of menaquinone. Structure–activity relationships are evaluated, as well as results translating these relationships to growth inhibition studies. Menaquinone is essential in electron transport and ATP generation in all Gram-positive, and anaerobically respiring Gram-negative bacteria. Inhibition of menaquinone production at different steps of the biosynthesis pathway has shown promising novel antibacterial action.
