Compounds with high anti-tumor activity and of moderate toxicity are described which are constituted by tripeptides formed from dichlorodiethylaminophenylalanine, para-fluorophenylalanine and methionine bonded together by peptide links. The tripeptides of the invention are particularly useful in the treatment of malignant tumors.

N-Acyl derivatives of glucosamines made by linking an amino acid or oligopeptide having a m-di(2-chloroethyl)amino-L-phenylalanyl group, to the amino group of the glucosamines by a peptide bond, are endowed with strong anti-tumor action against transplanted neoplasma in animal. The compounds according to the present invention are of the general formula (I): ##STR1## where R.sub.1 is a hydrogen atom or an acetyl group, R.sub.2 is a hydrogen atom, an acetyl group, aliphatic (C.sub.1 -C.sub.6) group or a benzyl group and R.sub.3 is m-di(2-chloroethyl) amino-L-phenylalanine, or L- methionyl -m-di(2-chloroethyl) amino-L-phenylalanyl-p-fluoro-L-phenylalanine, or p-fluoro-L-phenylalanyl-m-di (2-chloroethyl) amino-L-phenylalanyl-L-proline, or m-di (2-chloroethyl) amino-L-phenylalanyl-L-methionyl-p-fluoro-L-phenylalanine. The antineoplasmic activity of the compounds of the present invention is not affected in the gastrointestinal tract and hence they can be effectively administered orally.
