Novel cAMP PDE III Inhibitors: 1,6-Naphthyridin-2(1H)-ones

Two series of medorinone (3) analogs were prepared by modifications at C(2) and C(5).The C(2)-series was prepared from 2-chloro-5-methyl-1,6-naphthyridine (4) by replacement of the chloro group with various nucleophiles.The C(5)-series was prepared from 5

5-(Phenyl)-1,6-naphthyridin-2(1H)-ones, their cardiotonic use and preparation

1-R-5-Ar-1,6-naphthyridin-2(1H)-ones (I) or salts thereof, where R is hydrogen or methyl, and Ar is phenyl or phenyl substituted by methyl, ethyl, methoxy, ethoxy, hydroxy, amino, acetylamino, methanesulfonylamino, bromo, chloro, fluoro, cyano or carbamyl
