  A series of 2-guanidino-4-heteroarylthiazoles, wherein the heteroaryl substituent is selected from thiazolyl, triazolyl, imidazolyl, and 2-alkyl, 2-amino and 2-carboxamido derivatives thereof, are disclosed. The novel compounds have activity as antisecretory agents and histamine H.sub.2 antagonists and are useful for the treatment of gastric hyperacidity and peptic ulcers. Also disclosed are pharmaceutical compositions containing the novel compounds of this invention and a method of using the compounds in the treatment of gastric hyperacidity and peptic ulcers. Novel intermediates useful in the preparation of the novel antisecretory compounds are also described.

  本发明揭示了一系列2-胍基-4-杂环芳基噻唑化合物，其中杂环芳基取代基选择自噻唑基、三唑基、咪唑基和2-烷基、2-氨基和2-羧酰胺衍生物。这些新型化合物具有抗分泌作用和组胺H.sub.2拮抗剂作用，适用于治疗胃酸过多和消化性溃疡。本发明还揭示了含有这些新型化合物的制药组合物以及使用这些化合物治疗胃酸过多和消化性溃疡的方法。还描述了制备新型抗分泌化合物的新型中间体。
