evaluated them for their antimicrobial activity against S. aureus ATCC 29213 and M. tuberculosis H37Rv. These studies led to the identification of nine potent antibacterial agents 8a, 8b, 8c, 8d, 8f, 8g, 8h, 8i and 10c with MICs in the range of 4-64 μg/mL. Further, these selected compounds were found to possess potent antibacterial potential against a panel of drug-resistant clinical isolates which
由于抗生素抗性的迅速提高,传染病已成为对公共卫生的严重威胁。迫切需要开发具有多种化学结构和新颖的作用机制以克服耐药性的新型抗菌剂。近年来,喹唑啉-苯并咪唑杂合体已作为对金黄色葡萄球菌和结核分枝杆菌有活性的新型抗菌剂出现。在当前的研究中,我们设计和合成了15种新的喹唑啉-苯并咪唑杂种,并评估了它们对金黄色葡萄球菌ATCC 29213和结核分枝杆菌H37Rv的抗菌活性。这些研究导致鉴定出九种有效的抗菌剂8a,8b,图8c,图8d,8f中,8克,8H,8I和10C与在MIC值4-64的范围内μ克/毫升。此外,发现这些选择的化合物对包括耐甲氧西林和耐万古霉素的金黄色葡萄球菌在内的一组耐药临床分离株具有有效的抗菌潜力。被发现的选择的化合物是有毒的Vero细胞(CC少50 = 40≥200 μg / mL),并显示出良好的选择性指数。基于所获得的令人鼓舞的结果,这些新的苯并咪唑-2-基喹唑啉衍生物已成
