Description

APIM050404: Etoposide phosphate (BMY-40481)

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.

Background Information:

Etoposide phosphate (BMY-40481) (CAS No.: 117091-64-2), a semisynthetic derivative of podophyllotoxin that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.

Target: Topoisomerase II

IC50: 0.945 μM (HCT116 FBXW+/+), 0.375 μM (HCT116 FBXW-/-), and 1.437 μM (HCT116 p53-/-)

In Vitro: Etoposide phosphate 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.[1]
Etoposide phosphate (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.[2]
Etoposide phosphate (25 μM; 6 hours) delays p53 recover in FBXW7-deficient cells. In addition, FBXW7 expression is disappeared in FBXW7-/- cells.[2]

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.[3]

What is the solubility of Etoposide phosphate (BMY-40481) in vitro?
125 mg/mL in H2O (Need ultrasonic)
