4-Difluoro-substituted phenyl-5-oxohexahydroquinoline derivatives and their effects on calcium channels

Twenty new methyl(ethyl) 2,6,6- or 2,7,7-trimethyl-5-oxo-4-(disubstituted phenyl)-1,4,5,6,7,8-hexahydroquinoline-3-carboxylates and ten new N,N-diethyl-2,6,6- or 2,7,7-trimethyl-5-oxo-4-(disubstituted phenyl)-1,4,5,6,7,8-hexahydroquinoline-3-carboxamide derivatives have been synthesised and screened for their calcium channel antagonistic activity. The compounds were synthesised by the Hantzsch reaction. Calcium antagonistic activities of the compounds were determined by the tests performed on isolated rat ileum and rat thoracic artery.
