There are described compounds of formula I.
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,
R9 and R10 have a variety of significances, eg
R10 may form part of a double bond with L, or
the group -NR9R10 forms a ring carrying substituents R1 to R8.
or
when L is a single bond -NR10 and Re may form a ring carrying substituents R16 to R25, or
the group -LNR9R10 forms a heterocyclic ring carrying substituents R26 to R33,
R1 to R8 and R16 to R33 have a variety of significances
n is 0, 1 or 2,
x is 3, 4 or 5,
X is S, O or NR15,
R15 is hydrogen, -COR, -COOR or alkyl optionally substituted by -OCOR,
and certain provisos.
Processes for making the compounds and pharmaceutical formulations containing them, eg for the treatment of conditions involving excess gastric acid secretion, are also described.
