The invention relates to compounds of formula I and pharmaceutically acceptable salts and in vivo hydrolysable esters and amides thereof and processes for their preparation, their use as therapeutic agents and pharmaceutical compositions containing them. ##STR1## In formula I, A is a ring system in which the --CH(R.sup.3)N(R.sup.2)B--R.sup.1 and --OR.sup.4 groups are positioned in a 1,2 relationship to one another on ring carbon atoms. B is a ring system having R.sup.1 in a 1,3 or 1,4 relationship with the --CH(R.sup.3)N(R.sup.2)-- linking group. R.sup.2 is hydrogen or C.sub.1 -C.sub.6 -alkyl, R.sup.3 is hydrogen, methyl or ethyl, and R.sup.4 is C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -cycloalkyl-C.sub.1 -C.sub.3 -alkyl, C.sub.3 -C.sub.7 -cycloalkyl, N-oxides of --NR.sup.2, where chemically possible, or S-oxides of sulphur containing rings, where chemically possible. A, B, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may be substituted, as defined in the specification.
