pyridinecarbonitrile (5a) and the corresponding unsubstituted analogue 14a were the most potent positive inotropic agents in this series. Although the 4,6-dimethyl analogue 6a retained most of the activity of 5a, the 4-methyl analogue 8a was substantially less potent. The synthesis and structure-activity relationships are discussed.
