Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.250mg/ml (0.82mM)	Taking the 1 mL working solution as an example, add 50 μL of 5 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.250mg/ml (0.82mM)	Taking the 1 mL working solution as an example, add 50 μL of 5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. 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	GPNA hydrochloride (L-γ-glutamyl-p-nitroanilide hydrochloride) is a substrate of γ-glutamyltransferase (GGT) and an inhibitor of the glutamine transporter ASCT2 with an IC50 of ~250 μM in A549 cells. It also inhibits Na+-dependent carriers SNAT1, -2, -4, -5 and Na+-independent leucine transporters LAT1/2. It can be widely used in research on pancreatic cancer, breast cancer, glioblastoma multiforme, acute myelogenous leukemia, and non-small-cell lung cancer.
in vitro	GPNA leads to a significant decrease in endometrial cancer cell growth and spheroid cross-sectional area.^[1]
in vivo	EGFRAS-GPNA (EGFRAS-specific GPNA oligomers) is taken-up by several tissues including the xenograft tumor. Systemic administration of EGFRAS-GPNA induces antitumor effects in HNSCC xenografts, with similar efficacies as the FDA-approved EGFR inhibitors: cetuximab and erlotinib. EGFRAS-GPNA effectively againsts the constitutively active EGFR vIII mutant implicated in cetuximab resistance.
