Synthesis and Inhibitory Activity against COX-2 Catalyzed Prostaglandin Production of Flavone Analogs

  • Published : 2003.04.01

Abstract

To decipher the structure-activity relationships of flavones for the inhibition of cyclooxygenase-2 catalyzed prostaglandin production, we synthesized 7-methxoyflavones, 7-hydroxyflavones, 5-methxoyflavones, 5-hydroxyflavones and flavones without any phenol group on A ring. Methoxyflavones were prepared from 2.6- and 2,4-dihydroxyacetophenones in 3 steps. Most of the methxoyflavones were converted to the corresponding hydroxyflavones by the reaction with BBr3 in good yields. (omitted)
