A series of N-(2-(3,4,5-trimethoxybenzyl)-benzoxazole-5-yl)benzamide derivatives (3a–3n) was synthesized and evaluated for its in vitro inhibitory activity against COX-1 and COX-2. The compounds with considerable in vitro activity (IC50 < 1 µM), were evaluated in vivo for their anti-inflammatory and ulcerogenic potential. Out of the fourteen newly synthesized compounds; 3b, 3d, 3e, 3h, 3l and 3m were
合成了一系列N-(2-(3,4,5-三甲氧基苄基)-苯并恶唑-5-基)苯甲酰胺衍生物(3a-3n),并评估了其对COX-1和COX-2的体外抑制活性。对具有体外活性(IC 50 <1 µM)的化合物进行了体内抗炎和促溃疡作用的评估。在十四种新合成的化合物中;在使用IC 50的体外酶法测定中,发现3b,3d,3e,3h,3l和3m是最有效的COX-2抑制剂在0.14–0.69 µM的范围内。通过角叉菜胶诱导的大鼠爪水肿方法评估了这六个化合物(3b,3d,3e,3h,3l和3m)的体内抗炎活性。化合物3b(79.54%),3l(75.00%),3m(72.72%)和3d(68.18%)具有比标准药物布洛芬(65.90%)显着的抗炎活性。进行了具有组织病理学研究的致溃疡活性,并且所筛选的化合物显示出比布洛芬显着的胃耐受性。还通过解析COX-2的晶体结构进行了分子对接研究,以了解新合成的抑制剂与
