Substituted thienoimidazole derivatives, a process for the preparation thereof, pharmaceutical compositions containing them, and the use thereof as inhibitors of gastric acid secretion, as gastroprotectives and as medicaments for intestinal inflammations The invention relates to compounds of the formula ##STR1## in which A represents ##STR2## T denotes --S--, --SO-- or --SO.sub.2 --, R.sup.1 to R.sup.10, X, Y and Z have the meanings indicated in the description, to a process for the preparation thereof, to pharmaceutical compositions containing them, and to the use thereof as inhibitors of gastric acid secretion, as gastroprotectives and as medicaments for intestinal inflammations.
Three isomeric substituted thienoimidazothiazoles were synthesized as thiophene analogs of the immune modulator TILOMISOL, by cyclizing appropriate β-oxothioethers of thienoimidazoles. In contrast to the benzene analog no intermediates were observed at this step.
