A. Czompa et al., Synthesis and antioxidant activity of flavanoid derivatives containing a 1,4-benzodioxane moiety, ARCH PHARM, 333(6), 2000, pp. 175-180
Flavanoids bearing a 1,4-benzodioxane moiety [rac-15a. -16a, 17, -18, (-)-1
5a, (-)-16a] were prepared from protocatechualdehyde (5) and tested for inh
ibitory activity on the superoxide anion (O-2(.-)) release by human polymor
phonuclear leukocytes (PMNLs).
