analogues were synthesized and their inhibitory activities against Mycobacterium tuberculosis H37Rv determined in vitro alone and in combination with rifampicin (RIF). Some analogues showed comparable activity to verapamil and exhibited better synergies with RIF. Molecular docking studies of the binding sites of Rv1258c, a M. tuberculosis efflux protein previously implicated in intrinsic resistance
合成了新的维拉帕米类似物,并在体外单独或与利福平(RIF)联合测定了它们对结核分枝杆菌H37Rv的抑制活性。一些类似物表现出与维拉帕米相当的活性,并表现出与RIF更好的协同作用。Rv1258c的结合位点的分子对接研究是一种结核分枝杆菌外排蛋白,以前与RIF具有内在抗性有关,它提出了与某些类似物所观察到的优异协同相互作用的潜在原理。
