A series of gatifloxacin, ciprofloxacin, and 8‐OCH3 ciprofloxacin coumarin derivatives with remarkable improvement in lipophilicity as compared to the parent fluoroquinolones was designed, synthesized, and characterized by 1H‐NMR, MS, and HRMS. These derivatives were evaluated for their in‐vitro activity against Mycobacterium smegmatis CMCC 93202 and MTB H37Rv ATCC 27294. All of the synthesized compounds
设计、合成了一系列加替沙星、环丙沙星和 8-OCH3 环丙沙星香豆素衍生物,与母体氟喹诺酮类药物相比,亲油性显着提高,并通过 1H-NMR、MS 和 HRMS 进行表征。评估了这些衍生物对耻垢分枝杆菌 CMCC 93202 和 MTB H37Rv ATCC 27294 的体外活性。所有合成的化合物对耻垢分枝杆菌 CMCC 93202 的活性均低于母体化合物,但发现化合物 6 的活性为比环丙沙星、8-OCH3 环丙沙星、莫西沙星和利福平强 2-8 倍,与加替沙星对抗 MTB H37Rv ATCC 27294 的效果相当。这些结果表明测试化合物的亲脂性不是影响抗分枝杆菌活性的唯一参数。
