1-R"-3-Q-4-R'-5-R-1,6-naphthyridin-2(1H)-ones (I) or salts thereof, where R is lower-alkyl, R' is hydrogen or methyl, R" is hydrogen or lower-alkyl, and Q is hydrogen, hydroxy, amino, cyano, carbamyl, carboxy or aminocarbamyl, are useful as cardiotonic agents (I, Q is hydrogen, hydroxy, amino, cyano or carbamyl) and/or intermediates therefor (I, Q is carboxy, aminocarbamyl, hydrogen, amino, cyano or carbamyl). Also shown are 3-Q"-4-R'-5-(RCO)-6-[2-(di-lower-alkylamino)ethenyl]-2(1H)-pyridinones (II) or salts thereof, where R and R' are as above and Q' is hydrogen or cyano, which are useful as cardiotonics (II, Q' is hydrogen) and/or intermediates (II, Q' is cyano or hydrogen). Processes for preparing the compounds of formulas I and II are shown.
