Aminoacid and peptide derivatives of the formula: A--NH--R.sub.1 --CO].sub.x [NH--R.sub.2 --CO].sub.y NH--R.sub.4 --COOH in which A, R.sub.1, R.sub.2, x and y have the meanings specified in claim 1 for formula I, and R4 is a residue of an .alpha.-aminoacid which, when A is 4-allyloxy-3-chloro-phenylacetyl and x and y are 0, contains at least 2 carbon atoms, and their physiologically acceptable salts and lower alkyl ester. These compounds and 4-allyloxy-3-chloro-phenylacetylglycine have anti-inflammatory activity and pharmaceutical compositions containing them are described.
