title: [Potential cardiotonic agents. 6. Synthesis and cardiovascular properties of 5-(4-pyridinyl)-, 6-methyl-5-(4-pyridinyl)- and 6-methyl-5-phenyl-substituted 3-cyano-2-oxaalkyoxy-pyridines].
abstract: The headline compounds were prepared by the reaction of 2-chloropyridines 1-3 with the appropriate alcohols in presence of potassium hydroxide and the sodium alkoxides, respectively. Especially some of the 3-cyano-2-hydroxyalkoxy-5-(4-pyridinyl)pyridines showed remarkable positive inotropic potency and, additionally, a vasodilator activity. In spontaneously beating isolated guinea pig atria they had a greater activity than amrinone.
