4-phenylthieno[2,3-e][1,2,4] triazolo[4,3-a]pyrimidine-5(4H)-ones (5a-p) with triazole or other heterocyclic substituents (6-11) was synthesized and the compounds were evaluated for their anti-inflammatory activity using the xylene-induced ear-edema test. Pharmacological analyses showed that the compound 4-(4-chlorophenyl)thieno[2,3-e][1,2,4]triazolo[4,3-a]pyrimidine-5(4H)-one (5m) exhibited the greatest
一系列 4-苯基噻吩并[2,3-e][1,2,4] 三唑并[4,3-a]嘧啶-5(4H)-酮 (5a-p) 与三唑或其他杂环取代基 (6- 11) 被合成,并使用二甲苯诱导的耳部水肿试验评估化合物的抗炎活性。药理分析表明,化合物4-(4-氯苯基)噻吩并[2,3-e][1,2,4]三唑并[4,3-a]嘧啶-5(4H)-one(5m)表现出最大的抗炎活性(50.48% 抑制,腹腔给药后 30 分钟)并且比参考药物吲哚美辛更有效。口服4h后观察到5m的峰值活性,其抗炎活性高于100mg/kg剂量的消炎痛。
