  5-[1H-(5-membered-N-aromatic-heteryl)-1-yl]-7-R'-1,6-naphthyridin-2(1H)-ones (formula 1) or salts thereof are useful as cardiotonic agents. Also shown as intermediates are 5-X-7-R'-1,6-naphthyridin-2(1H)-ones (formula II) or salts thereof, where X is bromo, chloro or hydrazino, 2-[2-(di-lower-alkylamino)ethenyl)-1,6-dihydro-6-oxo-3-pyridinecarbonitrile (formula III), and 2-[2-(di-lower- alkylamino)-1-propenyl]-6-methoxy-3-pyridinecarbonitrile (formula IIIa). Processes shown include the preparation of I from II, preparation of II from III or IIIa and the preparation of III from 1,6-dihydro-2-methyl-6-oxo-3-pyridinecarbonitrile, and the preparation of IIIa from 6-methoxy-2-methyl-3-pyridinecarbonitrile.

  5-[1H-(5-membered-N-aromatic-heteryl)-1-yl]-7-R'-1,6-萘啶-2(1H)-酮（式 1）或其盐可用作强心剂。作为中间体的还有 5-X-7-R'-1,6-萘啶-2(1H)-酮（式 II）或其盐（其中 X 为溴代、氯代或肼代）、2-[2-（二低级烷基氨基）乙烯基]-1,6-二氢-6-氧代-3-吡啶甲腈（式 III）和 2-[2-（二低级烷基氨基）-1-丙烯基]-6-甲氧基-3-吡啶甲腈（式 IIIa）。所示工艺包括由 II 制备 I，由 III 或 IIIa 制备 II，由 1,6-二氢-2-甲基-6-氧代-3-吡啶甲腈制备 III，以及由 6-甲氧基-2-甲基-3-吡啶甲腈制备 IIIa。

  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-acyl-6-[2-(dimethylamino)ethenyl]-2-(1H)-pyridinone (11), 5-bromo-1,6-naphthyridin-2(1H)-one (17), and 1,3-diketones 19 and 27. 1,6-Naphthyridin-2(1H)-ones are novel inhibitors of cAMP PDE III. Modification of the carbonyl group of 3 or N-methylation at N(1) resulted in a dramatic loss of enzyme activity. Absence of the C(5)-methyl group of medorinone (3) or its shift to C(3) or C(7) also resulted in reduced activity. Substitution at C(3) also diminished activity. However, substitution at C(5) by a wide variety of substituents led to improvement of enzyme activity and several C(5)-substituted analogs were more potent than milrinone.
