Peptide derivatives selected from (i) a calcitonin peptide and a LHRH antagonist peptide modified by at least one sugar residue and/or at least one short polyhydroxy compound or derivative, and (ii) a calcitonin peptide modified by at least one formyl and/or at least C3-5alkyl attached to an amino group other than a N-terminal amino group, and (iii) a calcitonin peptide modified by a combination of said substituents, with the provisos that i) when the calcitonin peptide comprises at least one sugar residue a), this sugar residue is attached by a coupling other than a direct N-glycosidic bond to an omega -amino group of an omega -amino substituted side chain in the 24 position, and ii) when the LHRH antagonist comprises at least one sugar residue a), this sugar residue is an Amadori sugar residue attached by a coupling other than a direct N-glycosidic bond to an omega -amino group of an omega -amino substituted side chain in the 8 position in free form or in salt or complex form, have pharmacological activity.
