Menaquinone (vitamin K(2)) is an essential component of the electron transfer chain in many pathogens, including Mycobacterium tuberculosis and Staphylococcus aureus, and menaquinone biosynthesis is a potential target for antibiotic drug discovery. We report herein a series of mechanism-based inhibitors of MenE, an acyl-CoA synthetase that catalyzes adenylation and thioesterification of o-succinylbenzoic
甲萘醌(维生素 K(2))是许多病原体(包括结核分枝杆菌和金黄色葡萄球菌)中电子传递链的重要组成部分,甲萘醌生物合成是抗生素药物发现的潜在目标。我们在此报告了一系列基于机制的 MenE 抑制剂,MenE 是一种酰基辅酶 A 合成酶,可在甲基萘醌生物合成过程中催化邻琥珀酰苯甲酸 (OSB) 的腺苷酸化和硫酯化。最有效的化合物以 5.7microM 的 IC(50) 值抑制 MenE。
