Synthesis and antioxidant properties of some new flavone derivatives on lipid peroxidation in the rat liver.

ABSTRACT

A series of 2'-, 3'-, 4'- and 6-substituted flavone derivatives was synthesized and their in vitro effects on rat liver microsomal NADPH-dependent lipid peroxidation (LP) levels were determined. Retinoic acid, at 10(-4) M concentration, decreased the LP level by about 34%. A significant decrease in male liver microsomal LP level was noted for the compounds 3d, 1a, 3b and 4b at a concentration of 10(-4) M (100%, 95%, 75% and 62%, respectively).
