SHA-68 is a drug which acts as a selective, non-peptide antagonist at the neuropeptide S receptor NPSR. In animal studies it reduced motor stereotypes, and blocks the stimulant action of neuropeptide S. [1] [2]
Neuropeptide Y receptors are a family of receptors belonging to class A G-protein coupled receptors and they are activated by the closely related peptide hormones neuropeptide Y, peptide YY and pancreatic polypeptide. These receptors are involved in the control of a diverse set of behavioral processes including appetite, circadian rhythm, and anxiety.
Neurokinin 1 (NK1) antagonists (-pitants) are a novel class of medications that possesses unique antidepressant, anxiolytic, and antiemetic properties. NK-1 antagonists boost the efficacy of 5-HT3 antagonists to prevent nausea and vomiting. The discovery of neurokinin 1 (NK1) receptor antagonists was a turning point in the prevention of nausea and vomiting associated with cancer chemotherapy.
The galanin receptor is a G protein-coupled receptor, or metabotropic receptor which binds galanin.
The nociceptin opioid peptide receptor (NOP), also known as the nociceptin/orphanin FQ (N/OFQ) receptor or kappa-type 3 opioid receptor, is a protein that in humans is encoded by the OPRL1 gene. The nociceptin receptor is a member of the opioid subfamily of G protein-coupled receptors whose natural ligand is the 17 amino acid neuropeptide known as nociceptin (N/OFQ). This receptor is involved in the regulation of numerous brain activities, particularly instinctive and emotional behaviors. Antagonists targeting NOP are under investigation for their role as treatments for depression and Parkinson's disease, whereas NOP agonists have been shown to act as powerful, non-addictive painkillers in non-human primates.
The tachykinin receptor 1 (TACR1) also known as neurokinin 1 receptor (NK1R) or substance P receptor (SPR) is a G protein coupled receptor found in the central nervous system and peripheral nervous system. The endogenous ligand for this receptor is Substance P, although it has some affinity for other tachykinins. The protein is the product of the TACR1 gene.
The orexin receptor (also referred to as the hypocretin receptor) is a G-protein-coupled receptor that binds the neuropeptide orexin. There are two variants, OX1 and OX2, each encoded by a different gene (HCRTR1, HCRTR2).
The neuropeptide FF receptors are members of the G-protein coupled receptor superfamily of integral membrane proteins which bind the pain modulatory neuropeptides AF and FF. The Neuropeptide FF receptor family is a member of the G protein-coupled receptor superfamily containing two subtypes, NPFF1 and NPFF2, which exhibit a high affinity for Neuropeptide FF (NPFF) peptides. NPFF1 is broadly distributed in the central nervous system with the highest levels found in the limbic system and the hypothalamus. NPFF2 is present in high density, particularly in mammals in the superficial layers of the spinal cord where it is involved in nociception and modulation of opioid functions. These receptors participate to the modulation of opioid receptor function in the brain and spinal cord, and can either reduce or increase opioid receptor function depending which tissue they are released in, reflecting a complex role for neuropeptide FF in pain responses.
Orexin receptor type 2 (Ox2R or OX2), also known as hypocretin receptor type 2 (HcrtR2), is a protein that in humans is encoded by the HCRTR2 gene.
Neuropeptide Y receptor type 1 is a protein that in humans is encoded by the NPY1R gene.
Neuropeptide Y receptor type 2 (Y2R) is a member of the neuropeptide Y receptor family of G-protein coupled receptors, that in humans is encoded by the NPY2R gene.
Neuropeptide Y receptor type 5 is a protein that in humans is encoded by the NPY5R gene.
Tachykinin receptor 3, also known as TACR3, is a protein which in humans is encoded by the TACR3 gene.
JTC-801 is an opioid analgesic drug used in scientific research.
BIIE-0246 is a drug used in scientific research which acts as a potent and selective antagonist for the Neuropeptide Y receptor Y2. It was one of the first non-peptide Y2-selective antagonists developed, and remains among the most widely used tools for studying this receptor. It has been used to demonstrate a role for the Y2 subtype as a presynaptic autoreceptor limiting further neuropeptide Y release, as well as modulating dopamine and acetylcholine release. It has also been shown to produce several behavioural effects in animals, including reducing alcohol consumption in addicted rats and anxiolytic effects, although while selective Y2 agonists are expected to be useful as anorectics, BIIE-0246 did not appear to increase appetite when administered alone.
BIBP-3226 is a drug used in scientific research which acts as a potent and selective antagonist for both the Neuropeptide Y receptor Y1 and also the neuropeptide FF receptor. It was the first non-peptide antagonist developed for the Y1 receptor and has been widely used to help determine its functions in the body. Activation of Y1 is thought to be involved in functions such as regulation of appetite and anxiety, and BIBP-3226 has anxiogenic and anorectic effects, as well as blocking the Y1-mediated corticotropin releasing hormone release. It has also been used as a lead compound to develop a number of newer more potent Y1 antagonists.
UR-AK49 is a drug used in scientific research which acts as a potent antagonist for the Neuropeptide Y / Pancreatic polypeptide receptor Y4, and also as a partial agonist at the histamine receptors H1 and H2. UR-AK49 is a pure antagonist at Y4 with no partial agonist effects, and although it is only slightly selective for Y4 over the related Y1 and Y5 receptors, as the first non-peptide Y4 antagonist developed UR-AK49 is expected to be useful in the study of this receptor and its role in the body.
Neuropeptide S (NPS) is a neuropeptide found in human and mammalian brain, mainly produced by neurons in the amygdala and between Barrington's nucleus and the locus coeruleus, although NPS-responsive neurons extend projections into many other brain areas. NPS binds specifically to a G protein-coupled receptor, NPSR. Animal studies show that NPS suppresses anxiety and appetite, induces wakefulness and hyperactivity, including hyper-sexuality, and plays a significant role in the extinction of conditioned fear. It has also been shown to significantly enhance dopamine activity in the mesolimbic pathway, and inhibits motility and increases permeability in neurocrine fashion acting through NO in the myenteric plexus in rats and humans.
Lu AA-33810 is a drug developed by Lundbeck, which acts as a potent and highly selective antagonist for the Neuropeptide Y receptor Y5, with a Ki of 1.5nM and around 3300x selectivity over the related Y1, Y2 and Y4 receptors. In animal studies it produced anorectic, antidepressant and anxiolytic effects, and further research is now being conducted into its possible medical application in the treatment of eating disorders.
Neuropeptide VF precursor, also known as pro-FMRFamide-related neuropeptide VF or RFamide-related peptide precursor, is a propeptide that in mammals is encoded by the NPVF (or RPFP) gene. The NPVF gene, and thus the propeptide, are expressed in neurons in the mediobasal hypothalamus. The propeptide is cleaved to form three other peptides, which are:
Velneperit (S-2367) is a drug developed by Shionogi, which acts as a potent and selective antagonist for the Neuropeptide Y receptor Y5. It has anorectic effects and was developed as a possible treatment for obesity, but was discontinued from further development after disappointing results in Phase II clinical trials. However it was still considered a successful proof of concept of the potential of Y5 receptor antagonists as possible anti-obesity agents in future.
