We evaluated 44 novel cationic compounds for activity against metronidazole-sensitive and -resistant Trichomonas vaginalis isolates. Six compounds in three different structural classes demonstrated 50% inhibitory concentrations as low as 1 microM against both sensitive and resistant isolates, suggesting a mode of action independent of parasite biochemical pathways that confer resistance to 5-nitroimidazoles.
我们评估了44种新型阳离子化合物对甲硝唑敏感和耐药的阴道毛滴虫分离株的活性。三种不同结构类别的六种化合物对敏感和耐药分离株均表现出低至1微摩尔的50%抑制浓度,这表明其作用方式独立于赋予对5-硝基咪唑耐药性的寄生虫生化途径。
