Compounds of general formula (1): ##STR1## are described wherein Het is an optionally substituted heteroaromatic group; R.sup.1 is a hydrogen atom or a straight or branched chain alkyl group; R.sup.2 is a hydrogen or halogen atom or a group --X.sup.1 --R.sup.2a where X.sup.1 is a direct bond or a linker atom or group, and R.sup.2a is an optionally substituted straight or branched chain alkyl, alkenyl or alkynyl group; R.sup.3 is an optionally substituted aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are selective protein kinase inhibitors, particularly the kinases p56.sup.lck, ZAP-70 and protein kinase C and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate protein kinase action is believed to have a role.
