5g and 5h were found to be as potent as INH with MIC = 0.24 µg/mL, also the activity was evaluated against Isoniazid/Streptomycin resistant M. tuberculosis (ATCC 35823) where compounds 5g and 5h showed excellent activity (MIC = 3.9 µg/mL). Moreover, the target hybrids were examined against six bronchitis causing-bacteria. Most derivatives exhibited excellent antibacterial activity. K. pneumonia emerged
抽象的 为了加入全球抗击结核病这一世界上最致命的传染病的斗争,我们在此介绍了新型靛红-烟酰肼杂化物( 5a-m和9a-c )的设计和合成,作为有前途的抗结核和抗菌剂。针对药物敏感结核分枝杆菌菌株 (ATCC 27294) 评估了目标杂交体的抗结核活性,其中发现杂交体5d 、 5g和5h与 INH 一样有效,MIC = 0.24 µg/mL,活性也为针对异烟肼/链霉素耐药性结核分枝杆菌 (ATCC 35823) 进行了评估,其中化合物5g和5h显示出优异的活性 (MIC = 3.9 µg/mL)。此外,还对目标杂交体进行了针对六种引起支气管炎的细菌的检测。大多数衍生物表现出优异的抗菌活性。肺炎克雷伯菌成为最敏感的菌株,其 MIC 范围为:0.49–7.81 µg/mL。此外,分子对接研究提出 DprE1 作为本文报道的靛红-烟酰肼杂合体的可能酶靶标,并探索了 DprE1 活性位点附近的结合相互作用。
