Some novel 1-N-substituted thiocarbomoyl-3-ferrocenyl-2-pyrazoline derivatives were synthesized and evaluated for in vitro antiamoebic activity against HM1:IMSS strain of Entamoeba histolytica. The results showed that most of the compounds exhibited promising activity (IC50 values in the range of 0.050-1.683 μM) than the reference drug metronidazole (IC50 = 1.78 μM). Active compounds were further screened for cytotoxicity against human embryonic kidney-293 (HEK-293) normal cell lines to ensure their toxic effect and the results revealed that active compounds were least toxic in the concentration range of 2.5-50 μM for 48 h and 2.5-25 μM for 72 h. At 100 μM for 48 h and at 50 μM for 72 h only four compounds 2c, 2h, 2k and 2l showed maximum viability and least cytotoxicity, respectively, concluding that all the screened compounds were least cytotoxic against human embryonic kidney-293 (HEK-293) normal cell lines in the concentration range of 2.5-50 and 2.5-25 μM.
合成了一些新颖的1-N-取代硫代碳酰基-3-二茂铁基-2-吡唑啉衍生物,并评估了它们对Entamoeba histolytica的HM1:IMSS株的体外抗阿米巴活动。结果显示,多数化合物表现出比参考药物甲硝唑(IC50 = 1.78 μM)更有前景的活性(IC50值范围为0.050-1.683 μM)。进一步筛选活性化合物对人类胚胎肾-293(HEK-293)正常细胞系的细胞毒性,以确保其毒性效应,结果显示活性化合物在2.5-50 μM浓度范围内48小时和2.5-25 μM浓度范围内72小时内的毒性最小。在100 μM浓度下48小时和50 μM浓度下72小时,只有四种化合物2c、2h、2k和2l显示出最大的存活率和最小的细胞毒性,结论是所有筛选的化合物在2.5-50和2.5-25 μM浓度范围内对人类胚胎肾-293(HEK-293)正常细胞系的细胞毒性最小。
