Synthesis and Structure-Activity Relationships of Substituted 2-((2-Imidazolylsulfinyl)methyl)anilines as a New Class of Gastric H+/K+ -ATPase Inhibitors. II.
2-[(2-imidazolylsulfinyl)methyl]anilines (2) having various substituents on their imidazole and aniline rings was synthesized and examined for their H+/K(+)-ATPase (adenosine triphosphatase) inhibitory effects and antisecretory activity against histamine-stimulated gastric acid secretions in Heidenhain pouch dogs. Although substitutions on the imidazole ring did not enhance biological activity, substitutions
