There are described compounds of formula I,
in which R1, R2, R3, R4, Rs and R7,, which may be the same or different, each represent hydrogen, hydroxy, alkyl C1 to 6, alkoxy C 1 to 6, amino, acyl C2 to 6, acylamino C 2 to 6, alkenyl C 2 to 6, halogen, or alkoxy C 1 to 6 substituted by phenyl,
X is a hydrocarbon chain of 1 to 10 carbon atoms optionally substituted by a hydroxy group,
A is -Q-COOH,
0 is absent or represents a straight or branched alkylene, alkenylene or alkynylene group of up to and including 6 carbon atoms,
R8 and Rs, which may be the same or different, each represent hydrogen or alkyl C 1 to 6 or together form a single bond,
D, Y and Z, which may be the same or different, each represent sulphur, oxygen or -NR,o-, and
R10 is hydrogen or alkyl C1-C6,
provided that
i) when D, Z and Y are all oxygen, RB and R9 do not together form a single bond,
ii) when D is oxygen, R8 and R9 together form a single bond, X is (CH2)5, A is -COOH, one of Y and Z is sulphur and the other is oxygen, at least one of R1, R2, R3, R4, R5 and R7 is other than hydrogen,
and pharmaceutically acceptable salts, esters and amides thereof.
There are also described processes to these compounds, and pharmaceutical, e.g. anti-allergic, compositions containing them.
