AMG9810 is a competitive antagonist of capsaicin activation (IC50 value for human TRPV1, 24.5±15.7 nM; rat TRPV1, 85.6±39.4 nM) and blocks all known modes of TRPV1 activation, including protons (IC50 value for rat TRPV1, 294±192 nM; human TRPV1, 92.7±72.8 nM), heat (IC50 value for rat TRPV1, 21±17 nM; human TRPV1, 15.8±10.8 nM), and endogenous ligands, such as anandamide, N-arachidonyl dopamine, and oleoyldopamine. AMG9810 blocks capsaicin-evoked depolarization and calcitonin gene-related peptide release in cultures of rat dorsal root ganglion primary neurons. AMG9810 inhibits capsaicin-, proton-, heat-, and endogenous ligand-induced uptake of 45Ca2+ into TRPV1-expressing cells[1].

Protocol
Cultured adult rat dorsal root ganglia neurons in 96-well plates are washed twice with release buffer to initiate the assay. CGRP release is induced by incubation of neurons with capsaicin for 10 min at room temperature. The cultures are preincubated with increasing concentrations of capsazepine or AMG9810 for 15 min, followed by 300 nM capsaicin activation for 10 min at room temperature. The extracellular medium is collected and the CGRP content is determined using a commercially kit[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
To assess cyotoxicity of AMG9810, N/TERT1 cells are treated with different concentrations of AMG9810 (0.25, 0.5, 1, 5 μM) and cultured for various periods of time (24, 48, 72 h). The CellTiter 96 AQueous One Solution is added to each well and then cells are kept in a 37°C, 5% CO2 incubator for 1 h. Absorbance is then measured at 492 and 690 nm with a plate reader[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Rats: AMG9810 is dissolved in DMSO. Rats are acclimated for 30 to 45 min in a 30×30×30-cm Plexiglas chambers before the intraperitoneal injection of either vehicle (DMSO) or AMG 9810. Injections are made over a 5-s period in the lower right ventral quadrant of the abdomen either 15, 30, or 60 min before intraocular application of capsaicin. Intraocular application of capsaicin (3 μg/20 μL in 10% ethanol/PBS) or vehicle (20 μL in 10% ethanol/PBS) is done with a pipette, and the number of front paw eye wipes is counted over a 5-min period in 1-min intervals [1].
