Compounds of the general formula ##STR1## wherein Ph is a phenyl group which is optionally substituted by one or more substituents selected from halo (i.e. fluoro, chloro, bromo or iodo), C.sub.1-4 alkyl, amino, C.sub.1-4 alkylamino, di-C.sub.1-4 alkylamino, nitro, sulphonyl, aminosulphonyl, trihalomethyl, carboxy, C.sub.1-4 alkoxycarbonyl, amido, C.sub.1-4 alkylamido, C.sub.1-4 alkoxy, C.sub.2-4 alkenyl, cyano, aminomethyl, or methylsulphonyl; Y is a group of formula ##STR2## where R.sup.1 is hydrogen or methyl; R.sup.2 is alkyl of 1 to 3 carbon atoms or is methylthiomethyl; and Z is --OR.sup.3 or --NR.sup.4 R.sup.5 where R.sup.3, R.sup.4 and R.sup.5 are each hydrogen or alkyl of 1 to 4 carbon atoms and R.sup.3 can further be phenylalkyl having 1 to 3 carbon atoms in the alkylene moiety thereof, or phenyl; and basic salts thereof. These compounds have an advantageous enkephalinase inhibitory activity which renders the compounds useful in medical therapy, e.g. to prolong and/or potentiate in a mammal, the effects of endogenous or exogenous enkephalins. The latter includes synthetic enkephalin analogues.
