<p>The present invention relates to novel compounds of general formula (I), wherein R1 stands for hydrogen, halogen, C1-4 alkyl, C1-4 alkoxy or nitro group; R2 means a C1-7 alkyl group optionally substituted by: a hydroxyl or oxo group; or an ester group containing 1 to 4 carbon atoms in the alkoxy moiety; or a C1-4 alkoxy, cyano, amino, C1-4 alkylamino, or diakylamino group; or an acyl group containing 1 to 7 carbon atoms in the alkyl moiety; or R2 means an aryl-C1-7 alkyl group optionally bearing the substituents defined above for R2 in the alkyl chain and optionally substituted by halogen, nitro, C1-4 alkyl or alkoxy group in the benzene ring; or R2 represents an allyl, phenylallyl or phenylsulfonyl group, both latter groups optionally being substituted by halogen or a C1-4 alkyl group in the benzene ring; or R2 stands for a carbamoyl group substituted by one or two C1-4 alkyl group(s) or phenyl group on the nitrogen atom. The compounds according to the invention show a cytoprotective and acid secretion-inhibiting action and are effective against gastric and duodenal ulcers.</p> |
