The pyrazolo[3,4‐d]pyrimidine system shows a multitude of interesting pharmacological properties. Owing to the potential anti‐inflammatory activity of 5‐benzamido‐pyrazolo[3,4‐d]pyrimidin‐4‐one derivatives and considering the easy synthesis of this class of compounds, a set of new 5‐benzamido‐1H‐pyrazolo[3,4‐d]pyrimidin‐4‐ones has been prepared in 42‐80% yields by reacting 5‐aminopyrazole‐4(N‐benzoyl)carbohydrazide
吡唑并[3,4-d]嘧啶系统显示出许多有趣的药理特性。由于 5-苯甲酰胺基-吡唑并[3,4-d]嘧啶-4-one衍生物具有潜在的抗炎活性,并考虑到这类化合物的合成容易,研究人员开发了一套新的5-苯甲酰胺基-1H-吡唑并[3,4-d]嘧啶-4-one衍生物。通过 5-氨基吡唑-4(N-苯甲酰基)碳酰肼衍生物和合适的原三乙酯反应,3,4-d]嘧啶-4-酮的产率为42-80%。与参考标准 NS398 和吲哚美辛相比,化合物 8a、b、10a-d 和 11a、b 显示出对 COX-2 的优异抑制特性。分子模型研究证实了所获得的生物学结果。
