The purpose of this page is to explain a semisynthetic derivative of [http://en.wikipedia.org/wiki/Podophyllotoxin podophyllotoxin] [[Image:PODO.png|thumb|right|50 px|Chemical structure of podophyllotoxin]] (etoposide) that demonstrates antitumor activity by inhibiting DNA topoisomerase II, thereby inhibiting DNA re-ligation which lead to apoptosis of the cancer cell and also, to describe the mechanisms of resistance of etoposide.
