- Synthesis and antioxidant activity of flavanoid derivatives containing a 1,4-benzodioxane moiety
-
Flavanoids bearing a 1,4-benzodioxane moiety [rac-15a, -16a, -17, -18, (-)-15a, (-)-16a] were prepared from protocatechualdehyde (5) and tested for inhibitory activity on the superoxide anion (O2·-) release by human polymorphonuclear leukocytes (PMNLs).
