Abstract |
The effects of the novel acylquinoline derivative, 1-(2-methylphenyl)-4-[(3-hydroxypropyl)amino]-6-trifluoromethoxy-2,3- dihydropyrrolo[3,2-c] quinoline (AU-006) on experimental ulcer models and on gastric secretion were examined. AU-006 prevented dose dependently gastric lesions induced by 95% ethanol when given orally (30-300 mg/kg). Similarly, gastric lesions caused by 0.3 N NaOH were inhibited by oral pretreatment with AU-006. To investigate the anti- ulcer mechanism of AU-006, the effect of AU-006 on gastric acid secretion was tested. Intraduodenal administration of AU-006 reduced in vivo gastric acid secretion. The protective effect of AU-006 against gastric lesions induced by ethanol was not affected by a nitric oxide synthase inhibitor, NG-nitro-L-arginine-methyl ester ( l-NAME). In addition, the ethanol-induced mucus reduction was not recovered upon AU-006 administration. These results suggest that AU-006 is effective in the treatment of gastric ulcers by inhibiting gastric acid secretion, and that its activity is not related to either nitric oxide production or mucus secretion.
