histolytica. In vitro anti-amoebic activity was performed by microdilution method and the results were compared with standard drug metronidazole. The results revealed that sulphonamide derivatives (1–20) showed better activity than 4,6-disubstituted aminopyrimidines (1b–10b). 5 pyrimidine and 12 sulphonamide derivatives were better inhibitors of the growth of E. histolytica than the reference drug metronidazole
本研究描述了4,6-二取代的氨基嘧啶(1b – 10b)及其磺酰胺衍生物(1 – 20)的合成和抗厌氧活性。通过光谱数据表征所有所需化合物,并通过元素分析证实其纯度。本研究的目的是探讨目标化合物对溶组织变形杆菌的HM1:IMSS菌株体外生长的影响。通过微量稀释法进行体外抗厌氧活性,并将结果与标准药物甲硝唑进行比较。结果显示,磺酰胺衍生物(1 – 20)的活性比4,6-二取代氨基嘧啶(1b – 10b)。5个嘧啶和12个磺酰胺衍生物比参考药物甲硝唑(IC 50 = 1.80μM)更好地抑制了溶血性大肠杆菌的生长。该化合物具有良好的体外抗厌氧活性,使它们成为有希望的分子,可进一步开发新型抗厌氧剂,从而优化铅,因此,希望这些初步结果有助于设计出具有增强抗厌氧性的更好的分子。活动。
