New imidazo-heterocyclic compounds of the formula:
wherein
R' is hydrogen, lower alkyl or halogen,
R2 is hydrogen, lower alkyl, halogen, aminomethyl optionally substituted with lower alkyl, or piperazin-1-yl-methyl optionally substituted with lower alkyl,
R3 is a partially suturated heterocyclic group selected from benzothiazolinyl, benzoxazolinyl, benzimidazolinyl, 3,4-dihydro-2H-1, 4-benzothiazinyl, 3,4-dihydro-2H-1, 4-benzoxazinyl and 1,2,3,4-tetrahydroquinoxalinyl, which is substituted with oxo, thioxo, imino or lower alkylimino, and which may be substituted with lower alkyl optionally substituted with lower alkanoyloxy, lower alkoxycarbonyl, pyridyl or lower alkylamino; or
an unsaturated heterocyclic group selected from benzoxazolyl and benzimidazolyl, which may be substituted with lower alkyl or pyridyl (lower) alkylthio, and
Y is =N- or a group of the formula:
in which R' is hydrogen, hydroxy, lower alkyl, lower alkoxy or
ar(lower)alkoxy,
and pharmaceutically acceptable saltsthereof, and processes for preparation thereof and pharmaceutical composition comprising the same.
These derivatives and pharmaceutically acceptable salts thereof are useful as cardiotonic agents and antiulcer agents.
