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

The importance of internal hydrogen bonding in a series of benzothiadiazine and 1,4-benzothiazine NS5b inhibitors has been explored. Computational analysis has been used to compare the protonated vs. anionic forms of each series and we demonstrate that activity against HCV NS5b polymerase is best explained using the anionic forms. The syntheses and structure-activity relationships for a variety of new analogs are also discussed. (C) 2009 Elsevier Ltd. All rights reserved.
