New pyrimidine derivatives of the formula:
wherein Z is a group selected from
in which R1 and R2 are each hydrogen, alkenyl, ar (lower) alkyl or lower alkyl optionally substituted with epoxy, hydroxy, amino and/or lower alkylamino and R5 is lower alkyl,
R' is hydrogen, aryl optionally substituted with lower alkyl, lower alkoxy and/or halogen, or pyridyl optionally substituted with lower alkyl,
R4 is hydrogen, lower alkyl or phenyl optionally substituted with lower alkoxy, and
Y is =0, =S or =N-R6,
in which R6 is lower alkyl; cyclo(lower)alkyl; ar(lower)alkyl optionally substituted with lower alkoxy; N-containing unsaturated heterocyclic group optionally substituted with lower alkyl; or aryl optionally substituted with hydroxy, lower alkyl, halogen or lower alkoxy, in which lower alkoxy substituent may be substituted with epoxy, hydroxy, amino and/or lower alkylamino,
provided that Y is =N-R6 when R5 and R4 are each hydrogen, and Y is =S or =N-R6 when R' and R2 are each hyd- rogen or lower alkyl and R5 is phenyl, and pharmaceutically acceptable salts thereof, and processes for preparation thereof nad pharmaceutical composition comprising the same.
These derivatives and salts thereof are useful as cardiotonic, antihypertensive agent, cerebrovascularvasodilator and anti-platelet agent.
