Design, synthesis, biological evaluation and molecular modeling of dihydropyrazole sulfonamide derivatives as potential COX-1/COX-2 inhibitors.

Abstract:

:Novel dihydropyrazole sulfonamide derivatives (30-56) were designed, synthesized, and evaluated for their biological activities as COX-1 and COX-2 inhibitors. In vitro biological evaluation against three human tumor cell lines revealed that most target compounds showed antiproliferative activities. Among the compounds, compound 48 exhibited the most potent and selective COX-2 inhibitor (COX-2 IC50=0.33 μM; COX-1 IC50=68.49 μM) relative to the reference drugs celecoxib (IC50=0.052 μM). Docking simulation was performed to position compound 48 into the COX-2 active site and the result showed that compound 48 could bind well at the COX-2 active site and it indicated that compound 48 could be a potent and selective COX-2 inhibitor.
