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.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B 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.
