Clear solution
saline
10.0mg/ml Taking the 1 mL working solution as an example, add 10 mg of product to 1 ml of physiological saline (0.9% NaCL solution), and shake to clarify. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.95mg/ml Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 79 mg/ml to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; 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. 
* <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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description PX-478 2HCl is an orally active, and selective hypoxia-inducible factor-1α (HIF-1α) inhibitor. PX-478 2HCl induces apoptosis and has anti-tumor activity. Phase 1.
Targets
HIF-1α [1]
In vitro

PX-478 lowers HIF-1α protein levels and HIF-1 transactivation in hypoxia and in normoxia in a variety of cancer cell lines, but has a more pronounced effect on translation of proteins, such as HIF-1α in hypoxia. [2]

PX-478 also enhances the radiosensitivity of prostate carcinoma PC3 cells. [3]
In vivo

In HT-29 human colon cancer xenografts, PX-478 suppresses HIF-1alpha levels and inhibits the expression of HIF-1 target genes including vascular endothelial growth factor and the glucose transporter-1. In addition, PX-478 (100 or 120 mg/kg i.p.) also shows antitumor activity including cures against several established human tumor xenografts that is related to the levels of HIF-1α. [1]

In high-fat-diet mice, PX-478 causes reduced fibrosis and fewer inflammatory infiltrates in their adipose tissues. [4]
