observed after 19 days of sequential passaging. And 8 µg/mL of compound 9a displayed considerable post antibacterial effects to that of ciprofloxacin at the concentration of 2 µg/mL. Cytotoxic and ADMET studies indicated, to some extent, compounds 8f, 9a, and 9h were up to the standard for antibacterial drugs. These results suggest that indole/piperazine derivatives based on the title compounds can serve
在此,合成了一系列新型吲哚-哌嗪衍生物。生物测定结果表明,标题化合物对受试革兰氏阳性菌和革兰氏阴性菌(包括耐甲氧西林金黄色葡萄球菌(MRSA))表现出中等至良好的抑菌效果。在这些化合物中,三种显着的化合物8f、9a和9h表现出优于庆大霉素的抗金黄色葡萄球菌和抗 MRSA 的体外抗菌谱。Hit 化合物9a对 MRSA 表现出快速的杀菌动力学作用,连续传代 19 天后未观察到耐药性。和 8 µg/mL 化合物9a在 2 µg/mL 的浓度下,显示出比环丙沙星显着的后抗菌作用。细胞毒性和ADMET研究表明,化合物8f、9a和9h在一定程度上达到了抗菌药物的标准。这些结果表明,基于标题化合物的吲哚/哌嗪衍生物可以作为抗微生物开发的新支架。
