title: [Potential cardiotonics. 14. Synthesis and in vitro positive inotropic actions of 4-morpholino-5-(4-pyridinyl)pyridine derivatives].
abstract: By the reaction of 2-chloro-5-(4-pyridinyl)pyridines 1-6 with morpholine as well as by derivation of the 2-morpholino-pyridine-3-carboxamide 8 the 3-substituted 2-morpholino-5-(4-pyridinyl)pyridines 7-14 were prepared. The evaluation for positive inotropic properties in spontaneously beating isolated guinea pig atria gave for the 3-cyano derivative 7 (AWD 122-14) the best activity. The potency is comparable to that of milrinone and is due to partial by inhibition of phosphodiesterase III (PDE III).
