[Potential cardiotonic agents. 1. Synthesis and pharmacologic properties of 3-cyano-2-oxaalkylamino-5-(4-pyridinyl)pyridines].
Synthesis, physicochemical properties and evaluation of positive inotropic and vasodilator activities are described in a series of substituted 2-amino-3-cyano-5-(4-pyridinyl)pyridines. Some of the 2-oxaalkylamino derivatives showed remarkable positive inotropic activities and, additionally, a decrease in blood pressure. The most potent compounds 11 and 13 have a greater activity than amrinone.
