HEK293	IC₅₀	79 nM Compound: A967079	Antagonist activity at human TRPA1 expressed in HEK293 cells assessed as inhibition of CA-induced increase in calcium influx incubated for 10 mins prior to CA addition by Fluo-4-AM dye based fluorescence assayy Antagonist activity at human TRPA1 expressed in HEK293 cells assessed as inhibition of CA-induced increase in calcium influx incubated for 10 mins prior to CA addition by Fluo-4-AM dye based fluorescence assayy	[PMID: 30878828]

In Vivo

Systemic injection of A-967079 (30 μmol/kg, i.v.) decreases the responses of wide dynamic range (WDR), and nociceptive specific (NS) neurons following noxious pinch stimulation of the ipsilateral hind paw in uninjured and CFA-inflamed rats. Similar to its actions in uninjured rats, administration of A-967079 (30 μmol/kg, i.v.) to complete Freund's adjuvant (CFA)-inflamed rats significantly reduces WDR neuronal responses to noxious pinch stimulation compared to baseline firing (p=0.0013, repeated-measures ANOVA) and the vehicle group (p=0.0001, two-way ANOVA). The maximum observed effect (61.1±10.97% decrease from baseline levels) on pinch-evoked activity in inflamed rats occur 35 min after injection. In contrast to uninjured rats, injection of A-967079 to CFA-inflamed rats also significantly (p=0.0004, and p=0.0001 for the repeated-measures and two-way ANOVA's, respectively) reduces responses of WDR neurons to 10-g von Frey hair stimulation. The maximal observed decrease in von Frey-evoked activity is 67.69±18.39% from baseline levels (35 min post-injection), and is thus comparable to the effects of A-967079 on pinch-evoked activity in inflamed rats^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (12.06 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (12.06 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Protocol

Animal Administration^[1]

Rats^[1]
Male Sprague-Dawley rats (250-400 g) are used for all experiments and are housed in a temperature controlled room with a 12/12-hr day/night cycle. Food and water are available ad libitum. Spontaneous and evoked neuronal activity is then measured 5, 15, 25, and 35 min after systemic injection of A-967079 (30 μmol/kg, i.v.) or vehicle (polyethylene glycol). The intravenous injection of A-967079 or vehicle is completed over a 6-7 min period. The i.v. dose of A-967079 is selected based on extrapolated plasma levels that are effective in behavioral studies^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
