A series of pyrazoline derivatives (1a–15a) was synthesized by cyclization of chalcones (1–15) with 2-[5-(4-methoxyphenyl)-1H-tetrazol-1-yl]acetohydrazide under basic conditions and were screened in vitro, to find out effect on the growth of HM1: IMSS strain of Entamoeba histolytica. The compounds 3a, 4a, 11a, 13a and 14a showed encouraging results with IC50 value in the range of 0.86–1.28 μM. However
一系列吡唑啉衍生物(的1A - 15A)由查耳酮环化(合成1 - 15)与2- [5-(4-甲氧基苯基)-1H-四唑-1-基]在碱性条件下乙酰肼和筛选体外,找出对HM1的增长效应:IMSS的应变阿米巴。化合物3a,4a,11a,13a和14a表现出令人鼓舞的结果,IC 50值在0.86-1.28μM的范围内。但是化合物13a在IC 50上显示出最有希望的结果 = 0.86μM,是甲硝唑(用于原生动物感染的标准药物)的一半。在人类肝癌细胞系(HepG2)中的细胞活力测试揭示了新合成化合物的无毒性质。安全性指数的计算方法使化合物13a具有较强的抗贫血性和最小的细胞毒性(SI => 116.28),几乎是甲硝唑的两倍。
