Popis: | 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 activities (TNF-α, IL-8 and MCP-1) at micro molar concentration which was found to be better than positive control i.e., piroxicam. Compound 9e marginally and compound 9h significantly inhibited PMA-induced MMP-9 gelatinase activity. Also compounds 9e and 9h greatly inhibited the PMA-induced monocyte-to-macrophage transformation, a pre-requisite step in the formation of atheroma. |
