V-9302 ASCT2 Antagonist

Name: V-9302
Brand: Selleck Chemicals
SKU: S8818
Rating: 5 (18 reviews)

Cat.No.S8818

V-9302 is a competitive small molecule antagonist of transmembrane glutamine flux, that selectively and potently targets the amino acid transporter ASCT2 (SLC1A5) with an IC50 value of 9.6 μM for inhibition of glutamine uptake in HEK-293 cells. V-9302 blocks Sodium-neutral AA transporter 2 (SNAT2, SLC38A2) and the large neutral AA transporter 1 (LAT1, SLC7A5) as observed in 143B osteosarcoma cells, HCC1806 breast cancer cells and Xenopus laevis oocytes. Dilution of PBS may cause a clear aqueous solution to turn into a uniform suspension.

Mechanism of Action

Targets/IC₅₀/Ki	ASCT2 (HEK293 cells) 9.6 μM
In vitro	V-9302 inhibits ASCT2-mediated glutamine uptake in human cells in a concentration-dependent fashion and exhibits a 100-fold improvement in potency (IC50 of this compound = 9.6 µM) over gamma-L-glutamyl-p-nitroanilide (GPNA; IC50 = 1000 µM).
In vivo	Pharmacological blockade of ASCT2 with V-9302 results in attenuated cancer cell growth and proliferation, increases cell death, and increases oxidative stress, which collectively, contributes to anti-tumour responses in vitro and in murine models in vivo. The steady-state plasma concentrations are achieved 4 h post-administration, with a half-life of approximately 6 h in healthy mice. Following a single acute exposure to this compound (4 h), plasma glucose levels are not significantly different than vehicle controls, yet plasma glutamine levels are elevated by approximately 50% in treated mice compared to vehicle controls, likely a pharmacodynamic effect. Plasma glucose levels in mice chronically exposed to this chemical or vehicle over a 21-day regimen are not significantly different, while plasma glutamine levels are slightly decreased.

Frequently Asked Questions

Question 1:
What should be done if the water soluble mother liquor of it becomes cloudy when diluted into cell medium or PBS solution?

Answer:
During cell experiments, the mother liquor prepared with pure water may temporarily become turbid after adding PBS. It can be clarified again by standing at room temperature for half an hour. For animal experiments, please directly use PBS to prepare it.
