Compounds of the general formula I: ##STR1## and pharmaceutically acceptable salts thereof in which: A represents the group ##STR2## or the group ##STR3## linked to the adjacent benzene ring through the nitrogen atom, in which R.sub.1 represents a hydrogen atom, or an alkyl group which may optionally be substituted by one or more aryl, aryloxy, alkoxy, acyloxy, amino, alkylamino, dialkylamino or hydroxy groups or represents an alkenyl group; R.sub.2 represents a hydrogen atom, a halogen atom or an alkyl group or the group OR.sub.3, where R.sub.3 is a hydrogen atom or an alkyl group which may optionally be substituted by one or more aryl, aryloxy, alkoxy, acyloxy, hydroxy, amino, alkylamino or dialkylamino groups or the group NR.sub.4 R.sub.5 where R.sub.4 and R.sub.5 may be the same or different and have the meanings given for R.sub.1 or R.sub.4 and R.sub.5 together with the nitrogen atom form a 5 or 6 membered heterocyclic ring which may optionally contain additional hetero atoms; R.sub.6 and R.sub.7 which may be the same or different represent a hydrogen atom, or a halogen atom or an alkyl group or the group OR.sub.3 or the group NR.sub.4 R.sub.5 as defined above. These compounds have activity as for the treatment of conditions caused primarily by the combination of an antigen with a reaginic antibody.
