  摘要：

  A series of 2,4-dihydro-5-[4-(1H-imidazol-1-yl)phenyl]-3H-pyrazol-3-ones was synthesized and evaluated for positive inotropic activity. Only compounds with two small alkyl groups at C-4 showed significant activity. The structure-activity relationships for optimal inotropic activity are presented and compared with those of the 4,5-dihydro-3(2H)-pyridazinone series. The phosphodiesterase inhibitory activity is also reported and correlated with the substitution pattern at C-4 in the pyrazolone ring.
