Synonyms:

  • etoposide phosphate
  • etopofos
  • etopophos
Etoposide phosphate is a prodrug that is converted to its active moiety, etoposide, by dephosphorylation. Etoposide causes the induction of DNA strand breaks by an interaction with DNA-topoisomerase II or the formation of free radicals, leading to cell cycle arrest, primarily at the G2 stage of the cell cycle, and cell death.
