There are described compounds of formula I, ##STR1## in which A is a benzene or heterocyclic ring, y is 0 or 1, L is a group containing 1 or 2 carbon atoms, or is a single bond, R.sub.9 and R.sub.10 have a variety of significances, e.g. R.sub.10 may form part of a double bond with L, or the group --NR.sub.9 R.sub.10 forms a ring carrying substituents R.sub.1 and R.sub.8, or when L is a single bond --NR.sub.10 and R.sub.8 may form a ring carrying substituents R.sub.16 to R.sub.25, or the group --LNR.sub.9 R.sub.10 forms a heterocyclic ring carrying substituents R.sub.26 to R.sub.33, R.sub.1 to R.sub.8 and R.sub.16 to R.sub.33 have a variety of significances n is 0, 1 or 2, x is 3, 4 or 5, X is S, O or NR.sub.15, R.sub.15 is hydrogen, --COR, --COOR or alkyl optionally substituted by --OCOR, and certain provisos. Processes for making the compounds and pharmaceutical formulations containing them, e.g. for the treatment of conditions involving excess gastric acid secretion, are also described.
