ibuprofen derivatives were synthesized starting from ibuprofen. Their chemical structure was confirmed by spectral data. All the compounds were tested for their COX inhibitory activity. RESULTS The best COX-2 activity and selectivity were obtained with compounds 5c and 5d, which were subjected to further in vivo testing (carrageenan-induced paw edema, rat serum PGE2, TNF- α and IL-6, hot plate latency test)
背景报道布洛芬在COX-2结合位点的结合方式表明,羧基在环氧合酶通道入口处与Arg-120和Tyr-355结合,不会延伸到口袋中。这解释了布洛芬的非选择性。基于这一事实,我们假设延长布洛芬中羧酸部分的长度并添加更多的大体积刚性基团以及带有氢键功能的大体积基团可能会增加布洛芬的选择性并减少副作用,同时保持其镇痛和抗炎活性。目的在这项工作中,设计和制备了四个系列的布洛芬衍生物。这些化合物是通过增加羧酸酯基团的长度以及大疏水基团的结合来设计的。方法以布洛芬为原料合成了四个系列的布洛芬衍生物。它们的化学结构由光谱数据证实。测试所有化合物的COX抑制活性。结果化合物 5c 和 5d 获得了最佳的 COX-2 活性和选择性,并对其进行了进一步的体内试验(角叉菜胶诱导的爪水肿、大鼠血清 PGE2、TNF-α 和 IL-6、热板潜伏期试验)研究它们的抗炎和镇痛活性以及它们对胃粘膜的影响。两种化合物的抗炎活
