8-OCH3 ciprofloxacin methylene and ethylene isatin derivatives with remarkable improvement in lipophilicity were synthesized in this study. These derivatives were evaluated for their in vitro activity against some mycobacteria. All of the synthesized compounds were less active than the parent 8-OCH3 ciprofloxacin against Mycobacteriumsmegmatis CMCC 93202, but most of the methylene isatin derivatives
本研究合成了一系列具有显着改善亲脂性的新型8-OCH 3环丙沙星亚甲基和亚乙基靛红衍生物。对这些衍生物针对某些分枝杆菌的体外活性进行了评估。所有的合成的化合物的比母体8-OCH活性较低3对环丙沙星中号ycobacterium耻垢CMCC 93202,但大部分的亚甲基靛红衍生物是活性高于8-OCH 3环丙沙星,环丙沙星,异烟肼和利福平对MTB H37Rv株ATCC 27294注意到化合物3b(MIC:0.074μM)比参考化合物对MTB H37Rv ATCC 27294的效力高2-13倍,化合物3f和3i - k(MIC:6.72-7.05μM)比母体8-OCH的效力高约1.6倍3环丙沙星,对MDR-MTB 09710的效力是环丙沙星的3.5倍。
