Definitions

  • the present invention relates to the field of melanocortin peptides .
  • Melanocortins (which used to be called me1anotropines also) are peptides originally derived from a larger precursor protein named pro-opiomelanocortin.
  • the natural melanocortins share the heptapeptide core sequence Met-Glu-His-Phe-Arg-Trp- Gly.
  • These melanocortins include ⁇ -MSH ( ⁇ -melanocyte stimulating hormone), ⁇ -MSH, ⁇ -MSH, ⁇ -LPH ( ⁇ -lipotropin hormone) and ACTH ( adrenocorticotrope hormone) .
  • Melanocortins have a wide range of biological activities.
  • MCR-1 Melanocortin receptor 1
  • MCR-2 is the ACTH receptor expressed in for instance the adrenal gland.
  • the invention provides a peptide having specific binding affinity for a melanocortine receptor, preferably the mc3, mc4 or mc5 receptor comprising the sequence
  • X and Y are amino acid residues and Z is an aromatic amino acid residue.
  • the above peptides are agonists for MSH activity which are highly potent.
  • a very important contribution to the high potency can be attributed to the 7-position (counted as in the original ACTH-molecule) which should be D-2-thienyl-Ala or 3-pyridyl-D-Ala and for which only very limited and very similar residues may be substituted without losing the increase in agonist potency.
  • Another important contribution to MSH agonistic activity is the omission of residues 1-3 and/or the omission of residues 11-13.
  • a high contribution to activity is also provided by the presence of an aromatic amino acid residue at position 9.
  • Positions 4 and 5 should normally not be omitted; these residues should be present though it is far less critical which amino acid residues are present at said positions. It is clear that at least conserved substitutions are allowed for these positions, but also less conserved substitutions will histidine residue at position 6 and the arginine residue at position 8 are quite important for activity and should only be replaced by very conservative substitutions, if at all. Especially the more important residues in general should not be all replaced by substitutes in one and the same molecule.
  • the preferred residue at position is Naftyl-alanine, be it- in the D-or in the L-configuration. The presence of this residue leads to a further increase in potency.
  • amino acid residue at position 10 is not essential for the activity of the molecule, but it does seem to have some effect. If a residue is present it is preferred that this residue is glycine or lysine, whereby the latter has the additional advantage that it provides a reactive moiety which can be used to couple the peptide to other molecules or to make the peptide cyclic. In the event that a cyclic peptide is to be produced, which is preferred, since the half-life of such a cyclic peptide is improved over the half-life of the linear form, then a reactive moiety at the other end should also be provided.
  • Cyclic peptides can however also be produced by providing reactive moieties outside the essential core that enable closure of the loop, such as reactive moieties leading to a lactam.
  • the preferred residues at positions X and Y are Nle for X and Gly or Asp for Y, whereby the presence of Asp leads to a further advantage in having a reactive moiety for making a lactam.
  • the peptides according to the invention are generally more potent than MSH itself.
  • the preferred peptides have potencies of up to 100 times the potency of MSH. Less potent peptides are within the scope of the present invention, since potency is not the only criterion which is required for a successful peptide-based drug.
  • half-life and selectivity are also important parameters. the regular in vitro tests as well as an in vivo test in rats whereby the grooming behaviour is measured.
  • the results in a grooming assay are good indications that the peptides will be able to activate the receptor and thereby the G-protein cascade coupled to said receptor and thus the peptides can be used as agonists for MC-receptors .
  • Targeting the MC-receptor in particular of the MC-4 receptor for which a particularly selective peptide has been provided by the present invention in an agonistic manner is useful in the treatment of CNS- disorders, neurophathies , obesity, and in particular for diabetes related neuropathy, as well as neuropathy as a result of cytotoxic treatments (chemotherapy and the like).
  • the present invention also provides pharmaceutical compositions capable of treating the above conditions. Dosages for such treatments will usually be given once a day in doses of about 1 ⁇ q to about 100 mg per dosage unit, preferably 10 ⁇ q - 10 mg, more preferably 50 ⁇ q - 1 mg. The dosage should result in a concentration in the body of between 0,1 nm and 1 ⁇ m, preferably 1 nM - 100 nM, most preferably 10 - 50 nM.
  • the compositions may comprise the usual additives for usual dosage formats for peptide drugs or for peptide derived drugs. The format is preferably an oral formulation such as a tablet, a granulate, a powder or a liquid formulation, although enteral and parenteral administrations may find application as well. Particularly preferred are compositions wherein a peptide according to the invention is combined with a drug aiming to prevent or that leads to neuropathy, such as insulin and cytotoxic agents.

In case that rats were used for more than one grooming experiment they were allowed to recover for at least 3 days between subsequent experiments.
