linyl))methane-1-thione derivatives (1a–8a) and 2-(5-substituted-3-phenyl-2-pyrazolinyl)-1,3-thiazolino[5,4-b]quinoxaline derivatives (1b–8b) and evaluated for their in vitro antiamoebic activity against HM1:IMSS strain of E. histolytica. All the compounds were characterized by electronic, IR, 1H NMR and mass spectroscopic data. It was observed that the antiamoebic activity enhances on modifying the
在努力开发有效的antiamoebic剂,我们已经合成的查耳酮(1 - 8),2-氨基-5-取代的- (3-苯基(2-吡唑啉基))甲烷-1-硫酮衍生物(1A - 8A)和2-( 5-取代的-3-苯基-2-吡唑啉基)-1,3-噻唑啉代[5,4- b ]喹喔啉衍生物(1b – 8b)并评估了它们对溶血性大肠杆菌HM1:IMSS菌株的体外抗氧活性。所有化合物的特征在于电子,IR,11 H NMR和质谱数据。观察到,通过改变查耳酮对吡唑啉和进而对喹喔啉的结构,抗厌氧活性增强。在人肾上皮细胞系上进行MTT测定以检查化合物的细胞毒性,并将结果与甲硝唑进行比较。与甲硝唑相比,化合物6b具有更好的抗氧活性和更低的毒性。
