There are provided compounds of the general formula (I): ##STR1## and physiologically acceptable salts thereof in which Z represents a group ##STR2## wherein R.sub.2 represents a hydrogen atom or a straight or branched chain alkyl radical, or Z can additionally represent a group ##STR3## and R.sub.1, R.sub.3 and R.sub.4, which may be the same or different, each represent a hydrogen atom, a cycloalkyl group, an aryl group which may optionally be substituted by one or more hydroxy, alkoxy, or halogen radicals, or a straight or branched alkyl or alkenyl group, which alkyl or alkenyl group may be substituted with an aryl group, which aryl group may optionally be substituted by one or more hydroxy, alkoxy or halogen radicals. The compounds possess spasmolytic and cAMP phosphodiesterase inhibitory activity.
