approach, which includes molecular modelling studies, three series of azole pyrazole derivatives were designed through two synthetic pathways. The synthesized compounds were biologically evaluated for their inhibitory activity towards M. tuberculosis and their protein binding affinity (KD). Series 3 biarylpyrazole imidazole derivatives were the most effective with the isobutyl (10 f) and tert‐butyl
无法治疗的结核分枝杆菌耐药菌株的出现是世界范围内的一个重大公共卫生问题,迫切需要寻找新的有效治疗方法。结核分枝杆菌细胞色素 P450 CYP121A1 由于其在分枝杆菌生长中的重要作用,是治疗结核病的有前途的药物靶点。采用包括分子模型研究在内的合理方法,通过两条合成途径设计了三个系列的唑吡唑衍生物。合成的化合物对结核分枝杆菌的抑制活性及其蛋白质结合亲和力(K D)进行了生物学评估。系列 3 联芳基吡唑咪唑衍生物对异丁基 ( 10 f ) 和叔丁基 ( 10 g ) 化合物最有效,表现出最佳活性(MIC 1.562 μg/mL,K D 0.22 μM ( 10 f ) 和 4.81 μM ( 10 g ) )。光谱数据表明,所有合成的化合物均产生血红素索雷带的 II 型红移,表明与血红素铁直接结合或(在观察到不太广泛的索雷位移)假定通过间质水分子间接结合。生物和物理化学特性的评估确定了以下活性要求:LogP
