activities by in vivo. 2-amino-4-(4-aminophenyl)-6-(2,4-dichlorophenyl)pyrimidine (5b) and 2-amino-4-(4-aminophenyl)-6-(3-bromophenyl) pyrimidine (5d) were found to be the most potent anti-inflammatory and analgesic activity compared with ibuprofen, reference standard. And also it was found that compound 5b identified as lead structure among all in both the activities. Pyrimidines which showed good anti-inflammatory
查耳酮衍生物(3a-m)是根据克莱森-施密特缩合反应,通过将4-氨基苯乙酮与各种取代的芳族和杂芳族醛缩合而制得的。这些查耳酮在碱性醇条件下与盐酸胍反应后,以定量收率得到2,4,6-三取代的嘧啶(5a-m)。所有新合成的嘧啶均通过IR,1 H-和13 C-NMR,电子电离(EI)质量和元素分析进行表征,并通过体内筛选抗炎和镇痛活性。将2-氨基-4-(4-氨基苯基)-6-(2,4-二氯苯基)嘧啶(5b)和2-氨基-4-(4-氨基苯基)-6-(3-溴苯基)嘧啶(5d)制成与布洛芬(参考标准)相比,被发现是最有效的消炎和镇痛活性。并且还发现在两种活性中,化合物5b均被鉴定为先导结构。显示出良好的抗炎活性的嘧啶类药物还显示出更好的镇痛活性。
