[MFLH][Cl]. Moreover, all salts with the exception of mefloquine docusate ([MFLH][AOT]) showed improved permeability and diffusion through synthetic membranes. Finally, in vitro activity studies against Mycobacterium tuberculosis revealed that these ionic formulations exhibited up to 1.5-times lower MIC values when compared with [MFLH][Cl], particularly mefloquine camphorsulfonates ([MFLH][(1R)-CSA], [MFLH][(1S)-CSA])
由于结核分枝杆菌耐药菌株的迅速发展,开发有效治疗结核病的新型药物工具已成为当务之急。在此,我们报告了一种新的潜在制剂,即抗疟药物甲氟喹(MFL),它与有机阴离子结合作为化学佐剂。盐酸甲氟喹([MFLH][Cl])与多种有机酸钠盐发生离子复分解反应,高收率地得到了8种甲氟喹有机盐。其中一种盐甲磺酸甲氟喹 ([MFLH][MsO]) 与 [MFLH][Cl] 相比具有更高的水溶性。此外,除多库酯甲氟喹 ([MFLH][AOT]) 之外的所有盐类均显示出通过合成膜的渗透性和扩散性得到改善。最后,针对结核分枝杆菌的体外活性研究表明,与 [MFLH][Cl] 相比,这些离子制剂的 MIC 值低 1.5 倍,特别是樟脑磺酸甲氟喹 ([MFLH][(1 R )-CSA],[ MFLH][( 1S )-CSA]) 和甲氟喹 HEPES ([MFLH][HEPES])。
