Biological Activity

PX-478 2HCl is an orally active, and selective hypoxia-inducible factor-1α (HIF-1α) inhibitor. 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. PX-478 also enhances the radiosensitivity of prostate carcinoma PC3 cells. PX-478 causes reduced fibrosis and fewer inflammatory infiltrates in high-fat-diet mice adipose tissues.

Method Western blot
Cell Lines MiaPaCa2 cells
Concentrations 10, 20, 50, 100, and 200 μM
Incubation Time 6h
Results When MiaPaCa2 cells were exposed to the highest concentration of PX-478 and noscapine, HIF-1 expression levels equaled to 55% and 62% of the control value, respectively.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
