Definitions

  • This invention relates to novel 5-bicyclic- heteroaryl-substituted-2-pyridones, useful as cardiotonic agents for the treatment of congestive heart failure, to their preparation and to pharmaceutical compositions comprised thereof.
  • Congestive heart failure is a life-threatening condition in which myocardial contractility is depressed so that the heart is unable to adequately pump the blood returning to it.
  • Normal pathologic sequelae include decreased cardiac output, venous pooling, increased venous pressure, edema, increased heart size, increased myocardial wall tension, and eventually cessation of contractility.
  • Digitalis gly ⁇ osides have long been used to increase myocardial contractility and reverse the detrimental changes seen in congestive heart failure. More recently, dopamine, dobutamine, and amrinone have been used to provide necessary inotropic support for the failing heart.
  • 5-pyridyl substituted pyridones reported by Lesher and Opalka, where cardiotonic activity is exhibited when the substituents in the 3-position of the pyridones are hydrogen, cyano, amino, acetylamino, loweralkylamino, or diloweralkylamino (see U.S. Pat. Nos. 4,004,012, 4,072,746, 4,107,315, 4,137,233); when the 3-position of the pyridone is substituted by diloweralkyl amino methylene malonate (see U.S. Pat No. 4,199,586); and when the 3-position is acylamino (see U.S. Pat.
