Synthesis and Structure-Activity Relationships of N-Substituted 2-((2-Imidazolylsulfinyl)methyl)anilines as a New Class of Gastric H+/K+-ATPase Inhibitors.
activity against gastricH+/K(+)-ATPase prepared from rabbit stomach and gastric acid secretions in Heidenhain pouch dogs. Monoalkyl substituents on the nitrogen atom of the aniline moiety markedly inhibited the enzyme activity to the same degree as omeprazole, a representative H+/K(+)-ATPaseinhibitor. Most of these compounds, administered at 3 mg/kg i.v. inhibited histamine-stimulated gastric acid secretion
