Claim:
A method for treatment of melanoma or hemoblastosis in mammals including humans, which method comprises administration of an effective amount of a peptide derivative of general formula (I) wherein: R 1 is (a) a C 1 -C 3 hydrocarbon radical substituted by a functional group selected from an amino, a C 1 -C 5 amido-, and a carboxylic group, the carboxylic group being optionally esterified; or (b) a C 1 -C 3 hydrocarbon radical simultaneously substituted by an amino group which is optionally substituted by an acyl substituent; or (c) a C 1 -C 3 hydrocarbon radical substituted by a 5-6 membered unsaturated heterocyclic group, wherein the hydrocarbon radical can simultaneously comprise an amino group optionally substituted by an acyl substituent; or (d) a saturated heterocyclic group; or (e) when n is 0 and k is 0, R 2 is a hydrogen atom or a carboxyl group that can be esterified; R 3 is: (a) a 5-6 membered saturated or unsaturated cyclic or heterocyclic group, or (b) a amino group; or (c) a carboxyl group which is optionally esterified; n=0-4 m=1-4, and k=0-1; or pharmaceutically acceptable salts thereof.
