Tachykinin Receptor 1
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. Properties Tachykinins are a family of neuropeptides that share the same hydrophobic C-terminal region with the amino acid sequence Phe-X-Gly- Leu- Met-NH2, where X represents a hydrophobic residue that is either an aromatic or a beta-branched aliphatic. The N-terminal region varies between different tachykinins. The term tachykinin originates in the rapid onset of action caused by the peptides in smooth muscles. Substance P (SP) is the most researched and potent member of the tachykinin family. It is an undecapeptide with the amino acid sequence Arg-Pro- Lys-Pro- Gln- Gln- Phe- Phe-Gly- Leu- Met-NH2. SP binds to all t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L-733,060
L-733,060 is a drug developed by Merck & Co., Merck which acts as an orally active, non-peptide, selective Receptor antagonist, antagonist for the Tachykinin receptor 1, NK1 Receptor (biochemistry), receptor, binding with a Dissociation constant, Ki of 0.08 nM. Only one enantiomer is active which has made it the subject of several Enantioselective synthesis, asymmetric synthesis efforts. L-733,060 has antidepressant and anxiolytic effects in animal studies, and reduces both the dopamine release and neurotoxicity produced by methamphetamine and cocaine. It shows anti-inflammatory and anti-Hepatotoxicity, hepatotoxic effects in animals, and counteracts the development of hyperalgesia following nerve injury. It also has Anticarcinogen, anticancer effects in a variety of ''in vitro'' models.

Casopitant
Casopitant (), former tentative trade names Rezonic (U.S.) and Zunrisa (Europe), is an NK1 receptor antagonist which was undergoing research for the treatment of chemotherapy-induced nausea and vomiting. It was under development by GlaxoSmithKline. In July 2008, the company filed a marketing authorisation application with the European Medicines Agency. The application was withdrawn and development was discontinued in September 2009 because GlaxoSmithKline decided that further safety assessment was necessary. However, a 2022 review listed casopitant as under development as a potential novel antidepressant for the treatment of major depressive disorder, with a phase 2 clinical trial Clinical trials are prospective biomedical or behavioral research studies on human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel vaccines, drugs, dietar ... having been completed.

Trifluoromethyl Compounds
The trifluoromethyl group is a functional group that has the formula -CF3. The naming of is group is derived from the methyl group (which has the formula -CH3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H–, 1,1,1-trifluoroethane –, and hexafluoroacetone –CO–. Compounds with this group are a subclass of the organofluorines. Properties The trifluoromethyl group has a significant electronegativity that is often described as being intermediate between the electronegativities of fluorine and chlorine. For this reason, trifluoromethyl-substituted compounds are often strong acids, such as trifluoromethanesulfonic acid and trifluoroacetic acid. Conversely, the trifluoromethyl group lowers the basicity of compounds like trifluoroethanol. Uses The trifluoromethyl group occurs in certain pharmaceuticals, drugs, and abiotically synthesized natural fluorocarbon based compounds. The medicinal use of the trifloromethyl group dates from ...

Maropitant
Maropitant (INN; trade name: Cerenia ), used as maropitant citrate (USAN), is a neurokinin-1 (NK1) receptor antagonist developed by Zoetis specifically for the treatment of motion sickness and vomiting in dogs. It was approved by the FDA in 2007 for use in dogs and in 2012 for cats. Maropitant has mild pain-relieving, anti-anxiety and anti-inflammatory effects. Veterinary uses Injectable maropitant is used in dogs to treat and prevent acute vomiting; tablets are used for preventing vomiting from a variety of causes, though it requires a higher dose to prevent vomiting from motion sickness. The injectable version is also licensed for preventing and treating acute vomiting in cats. Maropitant is effective in treating vomiting from a variety of causes, including gastroenteritis, chemotherapy, and kidney failure; when given beforehand, it can prevent vomiting caused by using an opioid as a premedication. Some have claimed that maropitant is better at treating vomiting than na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NK1 Receptor Antagonist
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. An example of a drug in this class is aprepitant. Chemotherapy-induced emesis appears to consist of acute and delayed phases. So far, the acute phase emesis responds to 5-HT3 antagonists while the delayed phase remains difficult to control. The discovery and development of NK1 receptor antagonists have elicited antiemetic effect in both acute and especially in delayed phases of emesis. Casopitant, netupitant and rolapitant are some newer additions in this group. Rolapitant has a significantly longer half-life of 160 hours and was approved by the US FDA in 2015. The first registered clinical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aprepitant
Aprepitant, sold under the brand name Emend among others, is a medication used to prevent chemotherapy-induced nausea and vomiting (CINV) and to prevent postoperative nausea and vomiting (PONV). It may be used together with ondansetron and dexamethasone. It is taken by mouth or administered by intravenous injection. Common side effects include tiredness, loss of appetite, diarrhea, abdominal pain, hiccups, itchiness, pneumonia, and blood pressure changes. Other severe side effects may include anaphylaxis. While use in pregnancy does not appear to be harmful, such use has not been well studied. Aprepitant belongs to the class of neurokinin-1 receptor antagonists medications. It works by blocking substance P from attaching to the NK1 receptors. Aprepitant was approved for medical use in the European Union and the United States in 2003. It is made by Merck & Co. It is on the World Health Organization's List of Essential Medicines. Medical uses Aprepitant is used to prevent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
