title: [Hexahydroquinolinones with calcium-modulatory effects--synthesis and pharmacologic action].
abstract: The hexahydroquinolinones 4a-I were prepared by Knoevenagel-reaction of cyclohexandione (1) and the aromatic aldehydes 2a-I and subsequent cyclising Michael-addition with methyl beta-aminocrotonate 3. The new compounds are characterized by IR-, 1H-NMR-and mass spectroscopy. At the electrically stimulated left guinea pig-atrium structures of type 4 show marked positive inotropic effects, whereas BaCl2-induced contractions of the guinea pig-ileum are supressed dose-dependently with activity rates comparable to those of nifedipine. Furthermore, relaxation of KCl-stimulated aorta-musculature is observed.
