A series of rhodanine derivatives RB1-RB23 were synthesized through a two-round screening. Their Mycobacterial tuberculosis (Mtb) InhA inhibitory activity and Mtb growth blocking capability were evaluated. The most potent hit compound RB23 indicated comparable InhA inhibiton (IC50 = 2.55 μM) with the positive control Triclosan (IC50 = 6.14 μM) and Isoniazid (IC50 = 8.29 μM). Its improved growth-blocking
通过两轮筛选合成了一系列的若丹宁衍生物RB1-RB23。评价了它们的分枝杆菌结核(Mtb)InhA抑制活性和Mtb生长阻断能力。最有效的命中化合物RB23表明InhA抑制剂(IC50 = 2.55μM)与阳性对照三氯生(IC50 = 6.14μM)和异烟肼(IC50 = 8.29μM)具有可比性。其改善的对Mtb的生长阻滞作用和低毒性吸引了进一步的发展。对接模拟揭示了该系列的可能结合模式,并选择了关键的相互作用残基,如Ser20,Phe149,Lys165和Thr196。3D-QSAR模型可视化了SAR讨论并暗示了新信息。修饰若丹宁部分附近的环境可能是以后研究中很有希望的尝试。
