These are described compounds of formula I,
in which X is -0-, -S- or -NR3-,
R3 is hydrogen or alkyl C 1 to 6,
A is -COOH or 5- (1H-tetrazolyl), and B is hydrogen,
or A and B together form a chain -N=N-NH-,
n1 is nyarogen or nyaroxy,
R2 is hydroxy or esterified hydroxy,
R6 is hydrogen or alkyl C 1 to 3,
R7 is hydrogen or methyl, and
R8 is alkyl C 1 to 4 optionally substituted by phenyl, provided that
when B is hydrogen, A is-COOH, X is-0-, R1 is hydrogen, R2 is hydroxy, R6 and R7 are both hydrogen then R8 is not propyl, and pharmaceutically acceptable derivatives thereof.
There are also described methods for making the compounds and pharmaceutical, e.g. gastric acid secretion inhibiting, compositions containing them.
