class of antiinfective agents against MDR Mycobacterium tuberculosis. In antitubercular screening against H37Rv and 11 clinically isolated strains of M. tuberculosis several derivatives (1o,3a,c,i,j,p) showed MIC(90) in the range 0.5-3.2 microg/mL. 3c showed no cytotoxicity and proved to be the most potent derivative exhibiting MIC(90)=0.5 microg/mL against all M. tuberculosis strains and infected human
在这项初步研究中,我们报告了3-甲基-9-取代-6-氧代-6,9-二氢-3H- [1,2,3]-三唑并[4,5-h]喹诺酮-碳含氧酸的活性和它们的酯类作为抗MDR结核分枝杆菌的新型抗感染药。在针对H37Rv和11种临床分离的结核分枝杆菌的抗结核筛选中,几种衍生物(1o,3a,c,i,j,p)的MIC(90)范围在0.5-3.2 microg / mL之间。3c没有显示出细胞毒性,并且被证明是对所有结核分枝杆菌菌株和受感染的人类巨噬细胞(J774-A1)表现出MIC(90)= 0.5 microg / mL的最有效衍生物。
