Novel series of 2,3-dihydro-2-oxo-1H-imidazo[4,5-b]quinolinyl amine derivatives of Formula
wherein R₁ is hydrogen, lower alkyl; R₂ is hydrogen, lower alkyl, lower alkoxy, halogen; R₃ is hydrogen, lower alkyl; R₄ is hydrogen, lower alkyl, alkanoyl, phenylalkanoyl wherein phenyl is optionally substituted with halogen, lower alkyl, lower alkoxy; R₃ and R₄ are joined together to form morpholinyl, piperidinyl or pyrrolidinyl optionally substituted with -CO₂R₅ or
-NR₅R₆ wherein R₅ is hydrogen or lower alkyl, and R₆ is hydrogen, lower alkyl, cycloalkyl; 4-R₇-piperazinyl wherein R₇ is -CO₂R₈ wherein R₈ is lower alkyl, phenyl optionally substituted with up to 2 halogen, lower alkyl or lower alkoxy; phenylalkanoyl of 7 to 10 carbon wherein phenyl is unsubstituted or independently substituted with up to 2 halogen, lower alkyl, lower alkoxy. The compounds are cyclic AMP phosphodiesterase inhibitors and are particularly useful as inhibitors of blood platelet aggregation and/or as cardiotonic agents.
