Etoposide prohibits DNA combination by forming a complex with topoisomerase II and DNA. This complex lead to breaks in double stranded DNA and inhibits repair by topoisomerase II binding. Collect breaks in DNA inhibits entry into the mitotic phase of cell division and causes cell death. Etoposide acts mainly in the G2 and S phases of the cell cycle.
