Abstract

Compounds are described of the formula ##STR1## wherein: R.sup.1 is C.sub.3-6 alkyl or C.sub.1-3 alkylthioC.sub.1-3 alkyl; PA0 R.sup.2 is an optionally substituted C.sub.1-6 alkyl or C.sub.1-6 alkoxy group, aryl, heteroaryl, arylC.sub.1-4 alkyl, heteroarylC.sub.1-4 alkyl or a side-chain of a natural .alpha.-amino acid; PA0 R.sup.3 is hydrogen, C.sub.1-6 alkyl, CHR.sup.4 COR.sup.5 (where R.sup.4 is a side-chain of a natural .alpha.-amino acid and R.sup.5 is hydroxyl, C.sub.1-6 alkoxy or NHR.sup.6 where R.sup.6 represents a hydrogen atom or a C.sub.1-6 alkyl group) or a group (CH.sub.2).sub.n X (where n is 1 to 6 and X is hydroxyl, C.sub.1-4 alkoxy, heteroaryl or a group NR.sup.7 R.sup.8 where R.sup.7 and R.sup.8 are each hydrogen or C.sub.1-6 alkyl or the group NR.sup.7 R.sup.8 forms a 5 to 7 membered cyclic amine); and PA0 Het is an optionally substituted cyclic imide where the cyclic imide ring system has the formula (i), (ii) or (iii) ##STR2## in which A, B, C and D are each CH or 1 or 2 of A, B, C and D represents N and the others represent CH, and E and F may each independently represent CH or N; and physiologically acceptable salts and solvates thereof. These compounds inhibit…
