Add time:07/15/2019    Source:sciencedirect.com

1-((2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)methyl)-4-substituted-phenylpiperazine moiety was prepared and has been found to be a new and selective ligand for the enzyme cyclooxygenase-2 (COX-2). The biological activity of compound 3k as anti-inflammatory agent was further investigated both in vitro and in vivo. Notably, compound 3k exhibited the best anti-inflammatory activity among the eleven designed compounds with no toxicity, as determined by the ulcerogenic activity. Computational docking studies also showed that compound 3k has interaction with COX-2 key residues in the active site. Compound 3k maybe a new anti-inflammatory lead-candidate as powerful and novel non-ulcerogenic.
