group with N-methyl group produced compounds 6a–f with anti-inflammatory activity in a quite similar manner to those of their parent derivatives. In this subgroup, 4-pyridyl derivative 6f showed the most potent anti-inflammatory activity relative to niflumic acid (80 % reduction in inflammation at 1-h postdrug administration). The compounds with highest anti-inflammatory activity were subjected to analgesic
合成了一系列新的基于尼氟酸的N-酰基hydr衍生物5a - p,并评估了它们的抗炎和镇痛活性。大多数化合物显示出抗炎活性,活性范围中等至优异(炎症减少20-80%)。其中,3-氯苯基5d和3-吡啶基衍生物5o相对于作为参考药物的尼氟酸表现出最有效的抗炎活性(给药后1小时分别减少77%,76%和70%的炎症)。另外,通过分子替换尼氟酸的简化Ñ与芳基Ñ-甲基基团产生的化合物6a - f具有抗炎活性,其母体衍生物具有非常相似的方式。在该亚组中,相对于尼氟酸,4-吡啶基衍生物6f表现出最有效的抗炎活性(给药1小时后炎症减少80%)。具有最高抗炎活性的化合物进行了镇痛分析,并显示了中度至优异的镇痛活性。相对于尼氟酸,化合物5j(4-甲氧基衍生物)表现出最高的镇痛活性(分别为97%和68%的活性)。
