Background:

Podofilox (Podophyllotoxin) is a potent inhibitor of microtubule assembly and DNA topoisomerase II.

Podophyllotoxin, a kind of non-alkaloid toxin lignan extracted from the roots and rhizomes of Podophyllum plant, has been shown to inhibit the growth of various carcinoma cells. Podophyllotoxin is a natural product that inhibits the polymerization of tubulin and has served as a prototype for the development of diverse antitumor agents in clinical use.
