The dormant and resistant form of Mycobacterium tuberculosis presents a challenge in developing new anti-tubercular drugs. Herein, we report the synthesis and evaluation of trisubstituted thiazoles as antituberculosis agents. The SAR study has identified a requirement of hydrophobic substituent at C2, ester functionality at C4, and various groups with hydrogen bond acceptor character at C5 of thiazole
结核分枝杆菌的休眠和耐药形式在开发新的抗结核药物方面提出了挑战。在此,我们报道了三取代
噻唑类作为抗结核剂的合成和评价。
SAR研究已经确定了
噻唑支架在C2处具有疏
水取代基,在C4处具有酯官能度以及在C5处具有氢键受体特性的各种基团的需求。这导致鉴定出13h和13p为先导化合物。这些化合物选择性地抑制了休眠的结核分枝杆菌H37Ra菌株和结核分枝杆菌H37Rv。重要的是,13h和13p对CHO细胞无毒。这13p显示出对耐多药结核病分离株的活性。
