Synthesis and pharmacological characterization of some benzazepinone derivatives. 
A series of some benzazepinone derivatives were prepared.  The compounds were evaluated for inotropic, chronotropic and calcium antagonist properties.  For the compounds bearing well-known alpha-blocking fragments, the antagonist potency at postsynaptic alpha-adrenoceptors was assessed.  The new compounds were less effective as bradycardic agents and calcium antagonists but show remarkable negative inotropic activity.
