Etoposide

Etoposide (VePesid) is a semisynthetic derivative of podophyllotoxin that is produced in the roots of the American mandrake, or May apple. Unlike podophyllo-toxin and vinca alkaloids, etoposide does not bind to mi-crotubules. It forms a complex with the enzyme topoiso-merase II, which results in a single-strand breakage of DNA. It is most lethal to cells in the S- and G2-phases of the cell cycle. Drug resistance to etoposide is thought to be caused by decreased cellular drug accumulation.

Etoposide is most useful against testicular and ovarian germ cell cancers, lymphomas, small cell lung cancers, and acute myelogenous and lymphoblastic leukemia. Toxicities include mild nausea, alopecia, allergic reaction, phlebitis at the injection site, and bone marrow toxicity.
