A series of novel aryl carbamate derivatives of metronidazole (MNZ) were designed, synthesized, and screened for antiamoebic activity. As compared to MNZ, most of the derivatives exhibited moderate to excellent activity against the HM1:IMSS strain of Entamoeba histolytica. Compounds 7, 14, 16, 19, and 21 exhibited the most promising antiamoebic activity with IC50 values of 0.24, 0.08, 0.26, 0.26, and 0.15 μM, respectively, compared to that of MNZ (1.78 μM). Moreover, from the toxicological studies of these compounds on human melanocytes, the melan-a cell line revealed that the potent compounds are nontoxic at concentrations ranging from 2.5 to 50 μM.
设计、合成并筛选了一系列新颖的甲硝唑(MNZ)芳基氨基甲酸酯衍生物的抗阿米巴活性。与MNZ相比,大多数衍生物对溶组织内阿米巴HM1:IMSS株显示出中等到优异的活性。化合物7、14、16、19和21展示出最有前景的抗阿米巴活性,其IC50值分别为0.24、0.08、0.26、0.26和0.15 μM,相比之下,MNZ的IC50值为1.78 μM。此外,对这些化合物在人类黑素细胞上的毒理学研究表明,当浓度在2.5至50 μM范围内时,强力化合物无毒。
