  • NPFF neuropeptide-binding protein
  • Antibodies increase analgesia caused by endogenous and exogenous opioids.
  • NPFF or NPFF analogs By direct injection of NPFF or NPFF analogs into the spinal cord (it), a prophylactic effect with long-lasting opioid-like analgesia and increased pain-relieving effects of morphine was obtained (Gouarderes et al., Eur. J. Pharmacol. 1993, 237 , 73-81; Kontinen and Kalso, Peptides 1995, 16, 973-977).
  • NPFF neuropeptide FF also appears to play a role in physiological processes such as insulin release, regulation of food intake, memory functions, blood pressure regulation and electrolyte balance play (Panula et. al., Prog. Neurobiol. 1996, 48, 461-487).
  • Nervous system such as the hypothalamus, medulla, and dorsal hearing of the spinal cord are restricted.

  • NPFF2 is identical to the receptor HLWAR77 originally described as orphan (Elshourbagy et al., J. Biol. Chem. 2000, 275 (34), 25965-71).
  • NPFFl and NPFF2 could be characterized as specific receptors with affinities in the nanomolar and subnanomolar range for the two neuropeptides FF and AF.

  • NPY Y2 neuropeptide Y
  • cholecystokinin A NPY Yl

  • NPVF neuropeptide VF
  • NPFF-related peptides both localized on the so-called NPVF gene, bind to the NPFF1 receptor comparatively with higher affinity and selectivity than NPFF and NPAV.
  • the NPVF peptides also block morphine-induced analgesia in acute and inflammatory pain models to a greater extent than NPFF and underline the importance of the NPVF / FF1 system as part of an endogenous anti-opioid mechanism (Q. Liu et al., J. Biol. Chem. 2002, 276 (40), 36961).
  • NPFFl and NPFF2 receptors in addition to their original pain-modulating effects, could also have an influence on the storage and use of body energy (I. Lefrere et al., J. Biol. Chem. 2002, 277 (42), 39169).
  • the DesaminoTyr-Phe-Leu-Phe-Gln-Pro-Gln-Arg-NH 2 peptide has been described as the first NPFF receptor antagonist to counteract the NPFF effects. After icv injection, this peptide attenuated the withdrawal symptoms in the case of morphine dependence (Malin et al., Peptides 1991, 12, 1011-1014). However, this peptide showed no bioavailability in the central nervous system. Optimization of the tripeptide Pro-Gln-Arg-NH 2 in a combinatorial approach led to dansyl-Pro-Gln-Arg-NH 2 , or dansyl-Pro-Ser-Arg-NH 2 , both with improved
  • Arg-Tyr-amide peptoid BIBP3226 originally described as an NPY Yl selective receptor antagonist, showed an affinity for the human and rat NPFF1 receptor 10-60 times higher than for the corresponding NPFF2 receptors (Bonini et al., J. Biol. Chem 2000, 275 (50), 39324-31). From a series of compounds derived from the NPY Yl selective antagonist BIP3226, selective hNPFFl receptor antagonists were obtained which showed affinities of 40-80 nM (Mollereau et al., Europ. J. Pharmacol. 2002, 45, 245-56) ,
  • WO 02/24192 AI describes synthetic NPFF ligands of peptide structure, based on arginine as the central building block.

  • NSAIDs non-steroidal anti-inflammatory drugs
  • canabinoids canabinoids
  • opioids canabinoids
  • morphine derivatives bind to the ⁇ -opioid receptor and have an analgesic effect.
  • Opioid binding to the ⁇ -opioid receptor is accompanied by the release of neuropeptide FF.
  • the released NPFF weakens the analgesic effect of the administered opioids and leads to tolerance towards opioids.
  • increasingly higher opioid doses have to be administered as a result of this tolerance, which can ultimately lead to serious side effects.
  • NPFF1 receptor mainly located in the central nervous system and the NPFF2 receptor predominantly in the spinal cord.
  • Activation of the NPFF2 receptors shows an opioid-like analgesic effect. Blocking the NPPFl receptors by an antagonist prevents the development of tolerance to opioids and additionally increases their effect.
  • the products defined there are partly known and partly new, and are distinguished by the valuable pharmacological property of blocking the interaction of neuropeptide FF with the neuropeptide FF1 receptor subtype.
