 Teniposide is a semisynthetic derivative of podophyllotoxin that exhibits antitumor activity. It inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent cells from entering into the mitotic phase of the cell cycle, and lead to cell death. The cytotoxic effects of teniposide are related to the relative number of double-stranded DNA breaks produced in cells, which are a reflection of the stabilization of a topoisomerase II-DNA intermediate. Teniposide acts primarily in the G2 and S phases of the cycle.
