Cytoprotective effects of chalcones from Zuccagnia punctata and melatonin on the gastroduodenal tract in rats.
The effects of 2',4'-dihydroxychalcone and 2',4'-dihydroxy-3'-methoxychalcone from Zuccagnia punctata Cav. (Fabaceae) and melatonin administration on ethanol-induced gastroduodenal injury were investigated in rats. Both chalcones showed significant preventive effects in treatment with melatonin previous to the necrotising agent. These effects could be due, in part, to the radical scavenging activity of the melatonin.
