Etoposide phosphate, 磷酸依托泊苷

Topoisomerase II inhibitor. Forms ternary complex with DNA and topoisomerase II to prevent re-ligation of DNA strands. Causes errors in DNA synthesis and apoptosis in cancer cells. Increases acetylation of eEF1A. Antitumor agent. Active in vivo and in vitro.

Etoposide Phosphate is a phosphate salt of a semisynthetic derivative of podophyllotoxin. Etoposide binds to the enzyme topoisomerase II, inducing double-strand DNA breaks, inhibiting DNA repair, and resulting in decreased DNA synthesis and tumor cell proliferation. Cells in the S and G2 phases of the cell cycle are most sensitive to this agent. (NCI04)

Etoposide phosphate is a furonaphthodioxole.
