A novel series of analogues of (E)-4,5-dihydro-6-[2-[4-(1H-imidazol-1-yl) phenyl]ethenyl]-3(2H)-pyridazinone was synthesized as a variation on the imazodan series. The compounds were evaluated for (i) hemodynamic activity, (ii) cyclic AMP-phosphodiesterase inhibitory activity (human platelets and guinea pig heart tissue), and (iii) platelet aggregation inhibitory activity. The insertion of the ethenyl
