10.0mg/ml Taking the 1 mL working solution as an example, take 10 mg of this product, add it to 1 ml of 10% Tween 80 clear solution, and mix evenly to form a uniform suspension. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 AMG 517 is a potent and selective TRPV1 antagonist, and antagonizes capsaicin, proton, and heat activation of TRPV1 with IC50 of 0.76 nM, 0.62 nM and 1.3 nM， respectively.
in vitro AMG 517 inhibits CAP- (500 nM), acid- (pH 5.0), or heat-(45 °C) induced 45Ca2+ influx into human TRPV1-expressing CHO Cells with IC50 of 0.76 nM, 0.62 nM and 1.3 nM. AMG 517 blocks capsaicin-, proton-, and heat-induced inward currents in TRPV1-expressing cells similarly. AMG 517 inhibits native TRPV1 activation by capsaicin in rat dorsal root ganglion neurons with an IC50 value of 0.68 nM. AMG 517 is a competitive antagonist of both rat and human TRPV1 with dissociation constant (Kb) values of 4.2 and 6.2 nM, respectively. AMG 517 is a highly selective TRPV1 antagonist. The IC50 value for AMG 517 is >20 μM against 2-APB-activated TRPV2 and TRPV3, 4-αPDD-activated TRPV4, allyl isothiocyanate-activated TRPA1, and icilin-activated TRPM8 in cell-based assays that measure agonist-induced increases in intracellular calcium in CHO cells recombinantly expressing the appropriate TRP channel. [1]
in vivo Oral administration of AMG 517 produces a dose-dependent increase in plasma concentrations, it also produces a dose-dependent decrease in the number of flinches induced by capsaicin treatment. The minimally effective dose (MED), based on a statistically significant difference in number of flinches from the vehicle versus capsaicin-administered group, is 0.3 mg/kg for AMG 517. The corresponding plasma concentrations are 90 to 100 ng/mL for AMG 517. AMG 517 (3 mg/kg) exhibits significant reductions in capsaicin-induced flinch up to 24 h after dosing. AMG 517 blocks thermal hyperalgesia in CFA model of pain.[1] AMG 517 elicits hyperthermia in rodents, dogs and monkeys but not in TRPV1 knockout mice. Interestingly, hyperthermia evoked by TRPV1-selective antagonists is attenuated after repeated dosing of these antagonists to rats, dogs and monkeys, and TRPV1 knockout mice does not exhibit an impairment of thermoregulation.[2]
特徴 Does not activate TRPV1 at concentrations ≤40 μM (measured by 45Ca2+ uptake into TRPV1-expressing cells), indicating that it is not a partial agonist.

キナーゼアッセイ Agonist-Induced 45Ca2+ Uptake Assay
Two days before the assay, cells are seeded in Cytostar 96-well plates at a density of 20,000 cells/well. The activation of TRPV1 and TRPV2 is followed as a function of cellular uptake of radioactive calcium. Capsaicin (0.5 μM), pH 5, and heat (45°C) are used as agonists for TRPV1, and 2-APB (200 μM) is used as the agonist for TRPV2. All of the antagonist 45Ca2+ uptake assays are conducted as reported previously and had a final 45Ca2+ concentration of 10 μCi/ml. Radioactivity is measured using a MicroBeta Jet. Data are analyzed using GraphPad Prism 4.01.
