Etoposide phosphate (BMY-40481) is a potent anti-cancer chemotherapy agent and a selective topoisomerase II inhibitor to prevent re-ligation of DNA strands. Etoposide phosphate is the phosphate ester prodrug of etoposide and is considered as active equivalent to Etoposide. Etoposide phosphate induces cell cycle arrest, apoptosis, and autophagy.

How to use

In Vitro:

Etoposide phosphate disodium is a water-soluble derivative and probable prodrug of etoposide characterized by the presence of a phosphate group in position 4' of the E ring of the etoposide molecule. Etoposide phosphate disodium (0-1 μM; 72 hours) inhibits HCT116 FBXW+/+, FBXW-/- and p53-/- as a dose-dependent manner, exhibits IC50 values of 0.945 μM; 0.375 μM; and 1.437 μM, respectively. Etoposide phosphate disodium (25 μM; 6 hours) delays p53 recover in FBXW7-deficient cells. In addition, FBXW7 expression is disappeared in FBXW7-/- cells.

In Vivo:

Etoposide phosphate (intravenous injection; 50, 100, or 150 mg/kg; single dose) has clinical symptomology of progressive ataxia, impaired righting reflex, and splaying and paresis of fore- and hindlimbs at day 8 in female CD-1 mice.
