Eight new sulfonilamidothienopyrimidinone derivatives (1-8) were synthesized and evaluated for their antiinflammatory
activity on the human keratinocyte line NCTC 2544. The potential anti-inflammatory activity of the derivatives
(1-8) was evaluated by determining, through Western blot, the expression of cyclooxygenase (COX)-2, inducible
NO synthase (iNOS), intercellular adhesion molecule-1 (ICAM-1), and the release of prostaglandins (PG)E2 and interleukin-
8 (IL-8). Moreover, through ELISA assay, the release of monocyte chemoattractant protein-1 (MCP-1), and interleukin-
8 (IL-8) was analyzed.
Our results demonstrated that the derivatives 3, 5, 6 and 8 act as excellent inhibitors of inflammatory markers: iNOS,
COX-2, ICAM-1, MCP-1, and IL-8. These findings could be useful for the development of new drugs for the treatment of
various inflammatory pathologies.
