revealed that the incorporation of longer alkyl chains to the C-6 position in resorcylic acid conferred antibacterial properties against Staphylococcus aureus and Bacillus subtilis. The resultant olivetolic acid (OA) derivatives with n-undecyl and n-tridecyl side-chains, even those lacking the hydrophobic geranyl moiety from their C-3 positions, exhibited strong antibacterial activities against B. subtilis
抗菌活性研究表明,在间苯二酚酸的 C-6 位上掺入较长的烷基链赋予了对金黄色葡萄球菌和枯草芽孢杆菌的抗菌特性。所得具有正十一烷基和正十三烷基侧链的橄榄酸 (OA) 衍生物,即使是那些在 C-3 位上缺乏疏水性香叶基部分的衍生物,也对枯草芽孢杆菌表现出很强的抗菌活性,MIC 值为 2.5 μM。此外,研究表明,大麻二酚酸(CBGA)的C-6位正庚基烷基链修饰有效增强了对枯草芽孢杆菌的活性,证明了烷基侧链在调节生物活性中的重要性。总体而言,本研究的结果为进一步评估 OA 和 CBGA 衍生物的抗菌活性以及其他各种生物活性提供了见解,特别是在核心骨架的烷基和异戊二烯基侧链位置优化了疏水性。新药物种子的发现。
