A series of novel 1,2-benzothiazine 1,1-dioxide-3-ethanone oxime N-aryl acetamide ether derivatives 7a–h and 9a–h were synthesized starting from sodium salt of saccharin 1 in series of steps. Final compounds 7a–h and 9a–h were evaluated for the anti-inflammatory activity and their ability to inhibit monocyte-to-macrophage transformation. Compounds 7e, 9b, 9e and 9h showed impressive anti-inflammatory
从糖精1的钠盐开始,按一系列步骤合成了一系列新颖的1,2-苯并噻嗪1,1-二氧化物-3-乙酮肟N-芳基乙酰胺醚衍生物7a – h和9a – h。评价了最终化合物7a – h和9a – h的抗炎活性及其抑制单核细胞向巨噬细胞转化的能力。化合物7e,9b,9e和9h在微摩尔浓度下显示出令人印象深刻的抗炎活性(TNF-α,IL-8和MCP-1),被发现比阳性对照(吡罗昔康)更好。化合物9e和化合物9h均显着抑制PMA诱导的MMP-9明胶酶活性。化合物9e和9h也极大地抑制了PMA诱导的单核细胞向巨噬细胞的转化,这是形成动脉粥样硬化的必要步骤。
