Deoxypodophyllotoxin (DPT), a derivative of podophyllotoxin, is a lignan with potent antimitotic, anti-inflammatory and antiviral properties isolated from rhizomes of Sinopodophullumhexandrum (Berberidaceae). Deoxypodophyllotoxin, targets the microtubule, has a major impact in oncology not only as anti-mitotics but also as potent inhibitors of angiogenesis[1]. Deoxypodophyllotoxin induces cell autophagy and apoptosis[2]. Deoxypodophyllotoxin evokes increase of intracellular Ca2+ concentrations in DRG neurons[3].
Deoxypodophyllotoxin (25-75 nM; 6-48 hours) increases the percentage of early apoptotic cell population from 2.05 to 5.62 and 18.49% for 24 h and 48 h, respectively[1].Deoxypodophyllotoxin (25-75 nM; 6-48 hours) treats SGC-7901 cells arrested in G2/M phase in time- and dose- dependent manners[1]. Deoxypodophyllotoxin (25-75 nM; 6-48 hours) results in a remarkably time- and dose-dependent decrease in Cdc2 and Cdc25C expression levels and increases cyclin B1 within 6h, decreases PARP, Bcl-2 and caspase-3 activity[1].

Deoxypodophyllotoxin (intravenously injected; 5, 10, and 20 mg/kg; 3 times a week; 28 days) suppresses the tumors in a dose-dependent manner, the growth of tumors is inhibited by 22.19%, 47.91% and 50.93% with DPT at 5, 10 and 20 mg/kg, respectively[1].
