摘要:
Amino acid amides of formula (I): ##STR1## wherein R.sup.1 -R.sup.5 and Y represent a variety of organic groups and atoms (including where R.sup.2, Y and the adjacent nitrogen atom together represent a thiazolidine or pyrrolidine group) and X represents carbonyl or sulfonyl are mostly new compounds and have valuable anti-tumor and immuno-regulatory activities. They may be formulated in compositions for pharmaceutical use.
