The antiulcer effects of 3,5,7-trihydroxy-2-(3,4-dihydroxyphenyl)-1-benzopyrylium chloride (IdB 1027) were assessed in various experimental models. Given orally, IdB 1027 antagonized gastric ulcerations induced by pylorus ligation, stress, nonsteroidal antiinflammatory drugs, ethanol, reserpine, histamine and duodenal ulceration induced by mercaptamine (cysteamine). Moreover it antagonized chronic gastric ulcers induced by acetic acid. Given intraperitoneally, it was more potent than after oral administration. IdB 1027 did not affect gastric secretion in pylorus-ligated rats and increased gastric mucus in normal animals both in the absence and in the presence of indometacin treatment. Tolerability was very good. These results indicate that IdB 1027 possesses a promising antiulcer activity, probably by potentiating the defensive barriers of the gastrointestinal mucosa.
