Based on 3 publication(s) in Google Scholar
A-803467 is a potent and selective tetrodotoxin-resistant Nav1.8 sodium channel blocker (IC50=8 nM). A-803467 has shown significant anti-nociception in neuropathic and inflammatory pain models. A-803467 enhances the chemosensitivity of conventional anticancer agents through interaction with the ATP-binding cassette subfamily G member 2 (ABCG2) transporter.

A-803467 selectively and significantly reverses the ABCG2-mediated multidrug resistance. A-803467 (7.5 μM) significantly increases the cytotoxicity of mitoxantrone and topotecan in ABCG2-transfected cell lines. A-803467 (7.5 μM) significantly enhanced theintracellular [3H]-MX accumulation in ABCG2-transfected cells. A-803467 (7.5 μM; 0~120 minutes) significantly blocks the intracellular [3H]-MX efflux at different time periods from ABCG2-transfected cells. A-803467 stimulates the ATPase activity of ABCG2[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
A-803467 in combination with topotecan, significantly decreases the tumor growth in mice implanted with ABCG2 overexpressing H460/MX20 cells. A-803467 effectively restores the sensitivity of tumors overexpressing ABCG2 transporter to topotecan without having any significant effect on tumors lacking ABCG2 expression[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.99 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
