The invention provides novel imidazoquinolines, processes for their preparation and pharmaceutical compositions containing them. The compounds have Formula I ##STR1## wherein A is a C.sub.1 -C.sub.4 straight or branched alkylene chain which may be saturated or unsaturated, B is a C.sub.2 -C.sub.4 straight or branched alkylene chain which may be saturated or unsaturated, R.sup.1 and R.sup.2 are the same or different and are hydrogen, C.sub.1-6 alkyl, C.sub.1-6 alkoxy, C.sub.1-6 alkoxyalkyl, C.sub.1-6 hydroxyalkyl, hydroxy, halogen, nitro, carboxy, carboxylic lower alkyl ester, carbamoyl, carbamoyloxy, cyano, loweralkanoyl, lower alkanoylamino or trifluoromethyl, Het is a heterocyclic group chosen from imidazolyl, imidazolinyl, benzimidazolyl, thiazolyl, thiazolinyl, quinolyl, piperidyl, pryidyl, benzothiazoly and pyrimidyl, any of which heterocyclic groups may be substituted, and x is 0 or 1, and pharmaceutically acceptable salts thereof. The compounds are anti-ulcer/anti-secretory agents.
