Some 1-benzyl-2-cyanimino- and 1-benzyl-2-nitroimino-1,2-dihydropyridines were synthesized as new potential antiulcer agents. Some of these compounds exhibited significant antisecretory activity in the Shay test, like 1-(2-chlorobenzyl)-2-cyanimino-1,2-dihydropyridine (3c, ED50 = 1.8 mg/kg po), and some also had a cytoprotective effect, like 1-benzyl-2-cyanimino-1,2-dihydropyridine (3a, ED50 = 10.0 mg/kg po), in a modified Robert test, depending on the substitution of the benzyl group.

The invention relates to novel pyridine derivatives of formula (I), ##STR1## wherein Q stand for a nitro or cyano group; and X.sup.1 and X.sup.2, independently from each other, represent hydrogen or halogen or a trifluoromethyl, a lower alkyl or alkoxy or nitro group bound to any of the carbon atoms of the phenyl ring. The invention further relates to pharmaceutical compositions containing these compounds and a process for their preparation. The compounds of formula (I) possess gastric acid secretion inhibiting, tissue-protecting, analgetic and mild antiinflammatory effects and are useful for therapeutical purposes.
