Abstract
A number of 8-substituted chrysin analogs have been prepared and evaluated for their inhibitory activities of cyclooxygenase-2 catalyzed prostaglandin E(2) and iNOS-mediated NO production. Analogs were prepared via Suzuki-Miyaura C-C cross coupling reaction of 8-iodo-5,7-dimethoxyflavone and alkyl/areneboronic acids as a key reaction. Among the analogs tested, 5,7-dihydroxy-8-(pyridine-4-yl)flavone (3d) showed strong biological activities against COX-2 catalyzed PGE(2) and iNOS-mediated NO production from LPS-induced RAW 264.7 cells compared to those of chrysin.Copyright © 2011 Elsevier Masson SAS.
