Product Description

Netupitant (formerly CID-6451149; AGE-94200; Ro 67-3189) is an orally bioavailable neurokinin 1 (NK1) receptor antagonist with potential antiemetic activity. It inhibits NK1 with a Ki of 0.95 nM. In 2018, the FDA approved the combination medication netupitant/palonosetron to prevent nausea and vomiting caused by acute and delayed chemotherapy, including highly emetogenic chemotherapy like cisplatin. Netupitant inhibits NK1-receptor binding of the endogenous tachykinin neuropeptide substance P (SP) by competitively binding to and blocking the activity of human substance P/NK1 receptors in the central nervous system (CNS). This may prevent chemotherapy-induced nausea and vomiting (CINV).

Biological Activity I Assay Protocols (From Reference)

Targets	Neurokinin-1 receptor
ln Vitro	Netupitant (CID-6451149) exhibits a high affinity for the human NK1 receptor (pKi=9.0), exhibiting selectivity over NK2 and NK3 (pKi=5.8 for both sites) by more than 1000 times[2]. Netupitant (1, 10, 100 nM) concentration-dependently antagonizes substance P's stimulatory effects, exhibiting irreversible antagonism (pKB=8.87) in CHO NK1 cells[2].
ln Vivo	Netupitant (CID-6451149; 1–10 mg/kg; ip) inhibits mice's typical scratching, biting, and licking response in a dose-dependent manner. When NK1 agonists are injected intracerebroventricularly, gerbils will tap their feet. Netupitant, administered intraperitoneally (ID50 1.5 mg/kg) or orally (ID50 0.5 mg/kg), will counteract this behavior in a dose-dependent manner[2]. Netupitant (0.1-3 mg/kg; intraperitoneally) inhibits the responses to SP-methylester (SP-OMe) in a concentration-dependent manner (mean pKB=9.24) in the detrusor muscle. Netupitant reduces the frequency of the bladder's reflex contractions[3].
Cell Assay	Cells are pre-incubated in growth media (control) or media containing antagonists for one hour at 37°C. To guarantee receptor saturation, antagonist concentrations must be at least 30 times higher than the Kd value. In order to allow antagonists that are still attached to receptors to dissociate, antagonists are removed from the cells after preincubation and they are rinsed with growth media alone for an extra hour. Then, isosmotic HEPES buffer (pH 7.4, 20 mM) is added to the cell media. This buffer contains the following concentrations of SP and NaCl: 3 nM to 1 mM; KCl (2 mM), MgCl2 (1 mM), CaCl2 (2 mM), Fluo-4 acetoxymethyl (AM) ester (2 mM), pluronic acid (0.04%), and MgCl2 (1 mM). The last incubation took place at 37 °C for one hour. In order to sequester the AM ester molecules into micelles for cellular uptake, pluronic acid is added as a nonionic surfactant.
