    摘要: Ortho-mercaptoaroylamides and pharmaceutically acceptable salts thereof exhibit hypoglycemic activity in warm-blooded animals. The compounds may be prepared directly by the reaction of a secondary amine with a 2-imino-1,3-benzothiazin-4-one or indirectly by the reaction of the desired amine with (ochlorocarbonylphenyl) dithioether followed by reduction of the disulfide linkage.
