silicon analogues as pharmacophore model also strongly correlate with the biological assays and suggest that the incorporation of silicon in the inhibitor scaffold could enhance their potency by stabilizing the hydrophobic residues at the binding pocket. The best docking hit, compound 12 showed an MIC of 0.1 μM against H37Rv with an acceptable in vitro ADME profile and excellent selectivity index. Overall
全球对治疗结核病的新分子的需求不断增长,迫切需要开发新的策略来对抗这种威胁。BM212 相关化合物被发现是有效的抗结核药物,并且它们抑制分枝杆菌酸转运蛋白 MmpL3,这是结核分枝杆菌的已知有效药物靶点。为了增强其抑制效力,设计、合成了几种与 BM212 相关的二芳基吡咯硅类似物,并评估了其抗结核活性。在阿尔马尔蓝测定中,发现大多数硅掺入化合物比母体化合物 (BM212) 更有效地对抗结核分枝杆菌(MIC = 1.7 μM,H37Rv)。MmpL3 晶体结构和硅类似物作为药效团模型的对接结果也与生物测定密切相关,表明在抑制剂支架中掺入硅可以通过稳定结合袋处的疏水残基来增强其效力。最佳对接命中化合物12对 H37Rv 的 MIC 为 0.1 μM,具有可接受的体外ADME曲线和出色的选择性指数。总的来说,本研究表明,设计的硅类似物,特别是化合物12可能是MmpL3本质上灵活的药物结合口袋的良
