SB-705498 is a drug which acts as a potent and selective blocker of the TRPV1 ion channel. [1] [2] It has been evaluated in clinical trials for the treatment of rhinitis and chronic cough. [3] [4] [5]
Resiniferatoxin (RTX) is a naturally occurring chemical found in resin spurge, a cactus-like plant commonly found in Morocco, and in Euphorbia poissonii found in northern Nigeria. It is a potent functional analog of capsaicin, the active ingredient in chili peppers.
The transient receptor potential cation channel subfamily V member 1 (TrpV1), also known as the capsaicin receptor and the vanilloid receptor 1, is a protein that, in humans, is encoded by the TRPV1 gene. It was the first isolated member of the transient receptor potential vanilloid receptor proteins that in turn are a sub-family of the transient receptor potential protein group. This protein is a member of the TRPV group of transient receptor potential family of ion channels.
TRPV is a family of transient receptor potential cation channels in animals. All TRPVs are highly calcium selective.
Capsazepine is a synthetic antagonist of capsaicin. It is used as a biochemical tool in the study of TRPV ion channels.
Transient receptor potential cation channel subfamily V member 4 is an ion channel protein that in humans is encoded by the TRPV4 gene.
Transient receptor potential cation channel, subfamily V, member 3, also known as TRPV3, is a human gene encoding the protein of the same name.
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.
GSK-189,254 is a potent and selective H3 histamine receptor inverse agonist developed by GlaxoSmithKline. It has subnanomolar affinity for the H3 receptor (Ki = 0.2nM) and selectivity of over 10,000x for H3 over other histamine receptor subtypes. Animal studies have shown it to possess not only stimulant and nootropic effects, but also analgesic action suggesting a role for H3 receptors in pain processing in the spinal cord. GSK-189,254 and several other related drugs are currently being investigated as a treatment for Alzheimer's disease and other forms of dementia, as well as possible use in the treatment of conditions such as narcolepsy, or neuropathic pain which do not respond well to conventional analgesic drugs.
SB-334867 is an orexin antagonist. It was the first non-peptide antagonist developed that is selective for the orexin receptor subtype OX1, with around 50x selectivity for OX1 over OX2 receptors. It has been shown to produce sedative and anorectic effects in animals, and has been useful in characterising the orexinergic regulation of brain systems involved with appetite and sleep, as well as other physiological processes. The hydrochloride salt of SB-334867 has been demonstrated to be hydrolytically unstable, both in solution and as the solid. Orexin antagonists have multiple potential clinical applications including the treatment of drug addiction, insomnia, obesity and diabetes.
Iodoresiniferatoxin (I-RTX) is a strong competitive antagonist of the Transient Receptor Potential Vanilloid 1 (TRPV1) receptor. I-RTX is derived from resiniferatoxin (RTX).
Relief from chronic pain remains a recognized unmet medical need. Consequently, the search for new analgesic agents is being intensively studied by the pharmaceutical industry. The TRPV1 receptor is an ion channel that has been implicated in mediation of many types of pain and therefore studied most extensively. The first competitive antagonist, capsazepine, was first described in 1990; since then, development of novel TRPV1 antagonists has come a long way. This effort has led to the identification of several TRPV1 antagonists that have entered clinical trials as analgesic agents. Should these new chemical entities relieve symptoms of chronic pain, then this class of compounds may offer one of the first novel mechanisms for the treatment of pain in many years.
Zucapsaicin (Civanex) is a medication used to treat osteoarthritis of the knee and other neuropathic pain. It is applied three times daily for a maximum of three months. Zucapsaicin is a member of phenols and a member of methoxybenzenes It is a modulator of transient receptor potential cation channel subfamily V member 1 (TRPV-1), also known as the vanilloid or capsaicin receptor 1 that reduces pain, and improves articular functions. It is the cis-isomer of capsaicin. Civamide, manufactured by Winston Pharmaceuticals, is produced in formulations for oral, nasal, and topical use.
LASSBio-881 is a drug which acts as both a non-selective partial agonist of the CB1 and CB2 cannabinoid receptors, and also as an antagonist of the TRPV1 receptor, as well as having antioxidant effects. It has potent anti-inflammatory and anti-hyperalgesic effects in animal studies.
The vanilloids are compounds which possess a vanillyl group. They include vanillyl alcohol, vanillin, vanillic acid, acetovanillon, vanillylmandelic acid, homovanillic acid, capsaicin, etc. Isomers are the isovanilloids.
Phenylacetylrinvanil (IDN-5890) is a synthetic analogue of capsaicin which acts as a potent and selective agonist for the TRPV1 receptor, with slightly lower potency than resiniferatoxin, though still around 300 times the potency of capsaicin. It is an amide of vanillylamine and ricinoleic acid, with the hydroxyl group on ricinoleic acid esterified with phenylacetic acid. It is used to study the function of the TRPV1 receptor and its downstream actions, and has also shown anti-cancer effects in vitro.
GSK1016790A is a drug developed by GlaxoSmithKline which acts as a potent and selective agonist for the TRPV4 receptor. It has been used to study the role of TRPV4 receptors in the function of smooth muscle tissue, particularly that lining blood vessels, lymphatic system, and the bladder.
AMG-9810 is a drug which acts as a potent and selective antagonist for the TRPV1 receptor. It has analgesic and antiinflammatory effects and is used in scientific research, but has not been developed for medical use. It has high antagonist potency and good bioavailability and pharmacokinetics, and so has been used to study the role of TRPV1 in areas other than pain perception, such as its roles in the brain.
HC-067047 is a drug which acts as a potent and selective antagonist for the TRPV4 receptor. It has been used to investigate the role of TRPV4 receptors in a number of areas, such as regulation of blood pressure, bladder function and some forms of pain, as well as neurological functions.
AMG-517 is a drug which acts as a potent and selective blocker of the TRPV1 ion channel. It was developed as a potential treatment for chronic pain, but while it was an effective analgesic in animal studies it was dropped from human clinical trials at Phase I due to producing hyperthermia as a side effect, as well as poor water solubility. It is still used in scientific research into the function of the TRPV1 channel and its role in pain and inflammation, and has been used as a template for the design of several newer analogues which have improved properties.
PF-05105679 is a drug which acts as a potent and selective blocker of the TRPM8 ion channel, which is the main receptor responsible for the sensation of cold. It was developed as a potential analgesic, and blocks the sensation of cold in both animals and human trials. It also lowers core body temperature in small mammals, but does not produce this effect in humans in the normal dosage range.
