PYRIDINE-PYRIMIDINONE DERIVATIVE, MANUFACTURE AND MEDICINAL COMPOUND

摘要

The invention relates to new pyridine-pyrimidinone derivatives corresponding to the following general formula (I) wherein R1 represents linear C1-6 alkyl or cycloalkyl and R2 represents linear C1-6 alkyl or R1 and R2 together with the nitrogen atom form a pyrrolidine or piperidine ring; Alk represents a linear alkylene chain C1-6; Q represents a benzene ring, furan ring, thiophene ring or thiazole ring; X represents oxygen, Y is a single bond and m is 2, 3 or 4 when Q represents benzene; X represents methylene, Y represents sulfur and m is 2 or 3 when Q is furan, thiophene or thiazole; and R3 represents a hydrogen atom or a lower alkyl group. These compounds show improved H2-antagonistic activity.
