Studies on antiulcer drugs. I. Synthesis and antiulcer activities of imidazo[1,2-a]pyridinyl-2-oxobenzoxazolidines-3-oxo-2H-1,4-benzoxazines and related compounds

A series of imidazo[1,2-a]pyridinyl-2-oxobenzoxazolidines (4a-i), -3-oxo-2H-1,4-benzoxazines (5a-q), their thio-analogues (4j-p and 5r-t) and 5,6,7,8-tetrahydroimidazo[1,2-a]pyridinyl derivatives (8 and 9) were synthesized and tested for anti-stress ulcer

Imidazo-heterocyclic compounds and pharmaceutical composition comprising the same

New imidazo-heterocyclic compounds of the formula: STR1 wherein R1 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: STR2 in which R4 is hydrogen, hydroxy, lower alkyl, lower alkoxy or ar(lower)alkoxy, and pharmaceutically acceptable salts thereof, and processes for preparation thereof and pharmaceutical composition comprising the same. These derivatives and pharmaceutically acceptable salts thereof are useful as cardiotonic agents and untiulcer agents.
