  Substituted hydroxycoumarins and 7- or 8-hydroxybenzo[f]coumarins were prepared by the treatment of phenols and naphthalenediols, respectively, with malic acid and H2SO4 under microwave irradiation. 7-or 8-Hydroxybenzo[f] coumarins and 6-hydroxybenzo[h] coumarin were synthesized by the reaction of naphthalenediols with ethylpropiolate in the presence of ZnCl2 in refluxing dioxane. The compounds were tested in vitro for their ability: (i) to interact with 1,1-diphenyl-2-picryl-hydrazyl (DPPH) stable free radical, (ii) to inhibit lipid peroxidation, (iii) to scavenge the superoxide anion, (iv) to inhibit the activity of soybean lipoxygenase and (v) to inhibit in vivo the carrageenin-induced rat paw edema. Most of them are potent superoxide anion scavengers and inhibit in vitro lipid peroxidation. The majority of the compounds did not show high lipoxygenase inhibitory activity. No differences were observed between biological responses of hydroxycoumarins and hydroxybenzocoumarins. Compound 3i was found to present a promising antioxidant profile. (C) 2008 Elsevier Ltd.
