Nicotinamide Derivatives as a New Class of Gastric (H+/K+)-ATPase Inhibitors. II. Synthesis and Structure-Activity Relationships of 2-((2,4-Dimethoxybenzyl)sulfinyl)-N-(4-pyridinyl)pyridine-3-carboxamides.
evaluated for their gastric antisecretory activity and the ability to inhibit cytochrome P450-dependent O-dealkylation of 7-ethoxycoumarin (7-EC) in rat liver microsomes. Several of the compounds synthesized exhibited potent inhibitory activities against both [14C]aminopyrine accumulation stimulated by dibutyryl cyclic AMP in isolated rabbit parietal cells and histamine-induced gastric acid secretion in
