The invention relates to new sulfonamidines of the general formula (I):
wherein R is a group selected from 2-[[(5-methyl-1H-imidazole-4-yl)methyl]thio]ethyl, 2-[[[5-[(dimethyl-amino)methyl]-2-furanyl]methyl]thioyethyl, 2-[[[2-[(aminoiminomethyl)ammol]-4-thiazolyl]methyl]thio]ethyl] or 3-[3-(1-piperi- dinylmethyllphenoxy]propyl and R, is alkyl; or a phenyl group optionally substituted by alkyl, halogen, nitro, alkoxy, alkanoylamino, carboxylic acid, alkoxycarbonyl, dialkylamino, alkylsulphonyl, alkylsulphonylamino or alkylthio; or 1,3,4-thiadiazole-2-yl substituted by alkanoylamino, and the pharmaceutically acceptable salts thereof, as well as to a process for preparing these compounds and to pharmaceutically compositions containing these compounds.
These compounds have antiulcer activity and can be used in the treatment of peptic ulcers and other pathologies caused or stimulated by gastric acidity.
本发明涉及通式(I)的新磺胺类化合物:
其中 R 是选自 2-[[(5-甲基-1H-咪唑-4-基)甲基]硫代]乙基、2-[[[5-[(二甲基氨基)甲基]-2-呋喃基]甲基]硫代乙基、2-[[[2-[(氨基亚氨基甲基)氨基]-4-噻唑基]甲基]硫代]乙基]或 3-[3-(1-哌啶基甲基苯氧基)丙基的基团,R 是烷基;或任选被烷基、卤素、硝基、烷氧基、烷酰氨基、羧酸、烷氧羰基、二烷基氨基、烷基磺酰基、烷基磺酰基氨基或烷基硫基取代的苯基;或被烷酰氨基取代的 1,3,4-噻二唑-2-基,及其药学上可接受的盐,以及制备这些化合物的工艺和含有这些化合物的药用组合物。
这些化合物具有抗溃疡活性,可用于治疗消化性溃疡和其他由胃酸引起或刺激的病症。
