[Antiulcer activity of furoxanopyrimidine derivatives].

A series of four new furoxanopyrimidine derivatives was synthesized and studied with respect to antiulcerous, antisecretory, and antibacterial activity. Two compounds exhibit antiulcerous effect not accompanied (in contrast to the well-known H2 receptor blockers, quiditene, and other antiulcerous drugs) by inhibition of gastric acid secretion. No one of the studied compounds exhibited antibacterial activity in the tests with Helicobacter pylori.
