    • The invention relates to a pro-drug comprising a cyclic undecapeptide wherein the peptide chain thereof comprises at least one amino acid residue of general formula (1) wherein the carbon atom C is one of the links in said undecapeptide cycle; - substituents Y individually represent a hydrogen atom or form a bond together; - substitutents R and R independently represent a hydrogen atom, an aralkyl group, an alkaryl group, a heteroalkyl group, a heterocyclic group, a heterocyclic alkyl group, an alkyl heterocyclic group or an alkyl group having 1-6 carbon atoms which is linear or branched, and which is optionally substituted by at least one of the groups chosen from among -COOH, -CONHR , -NHC0=NH(NH2), -NHC=NR (NH2), -NH2, -NHR , -NR 2, -N R 3, -OH, -OPO(OR )2, -OPO(OH)(OR ), -OPO(OH)2, -OSO(OR )2, -OSO(OH)(OR ), -OSO(OH)2, and the different salts produced therefrom, each of the substituents R independently representing an alkyl group which is linear or ramified having 1 - 6 carbon atoms; - substituents R and R independently represent a hydrogen atom, an alkaryl group or an alkyl group having 1 - 6 carbon atoms which is linear or branched; - the substituents R and R individually represent a hydrogen atom, an aralkyl group, an alkyl group having 1-6 carbon atoms which is linear or branched; and substituent R represents an alkaryl group, a heteroalkyl group, a heterocylic group,a heterocylic alkyl group, an alkyl heterocyclic group or an alkyl group having1 - 6 carbon atoms which is linear or branched.
