The invention relates to compounds of the general formula (I) ##STR1## and physiologically acceptable salts, hydrates and bioprecursors thereof, in which Q represents a benzene ring in which incorporation into the rest of the molecule is through bonds at the 1- and 3- or 1- and 4- positions: Z represents one of the groups ##STR2## where X represents NCN, NSO.sub.2 Methyl, NSO.sub.2 Phenyl or CHNO.sub.2. The compounds show pharmacological activity as selective histamine H.sub.2 -antagonists.
本发明涉及通式(I)的化合物及其生理上可接受的盐、水合物和生物前体,其中Q代表苯环,其嵌入到分子的其余部分是通过在1-和3-或1-和4-位置的键;Z代表以下一种基团之一:##STR2## 其中X代表NCN、NSO.sub.2甲基、NSO.sub.2苯基或CHNO.sub.2。这些化合物表现出选择性组胺H.sub.2-拮抗剂的药理活性。
