podophyllum peltatum

(-)-Epipodophyllotoxin (2) is an antiproliferative agent targeting cancer cells, exhibiting GI50 values of 0.36 μM in HeLa cells and 0.24 μM in MCF-7 cells, and inhibiting mitotic spindle assembly in vitro.

4'-Demethylpodophyllotoxin is isolated from the herb of Dysosma pleiantha (Hance) Woodson with remarkable cytotoxic potential in diverse cancer cell lines.

Picropodophyllotoxin (AXL 1717) is a cyclolignan alkaloid found in the mayapple plant family (Podophyllum peltatum), and a small molecule inhibitor of the insulin-like growth factor 1 receptor (IGF1R) with potential antineoplastic activity. Picropodophyllotoxin (AXL 1717) specifically inhibits the activity and downregulates the cellular expression of IGF1R without interfering with activities of other growth factor receptors, such as receptors for insulin, epidermal growth factor, platelet-derived growth factor, fibroblast growth factor and mast/stem cell growth factor (KIT). This agent shows potent activity in the suppression o f tumor cell proliferation and the induction of tumor cell apoptosis. IGF1R, a receptor tyrosine kinase overexpressed in a variety of human cancers, plays a critical role in the growth and survival of many types of cancer cells.

4-Demethyldeoxypodophyllotoxin, an aryl tetrahydronaphthalenyl lignan analog from the roots of Podophyllum peltatum, has anticancer activity and modulates the Chk-2 signaling pathway in MCF-7 breast cancer cells.

Podophyllotoxin glucoside is a natural product present in Podophyllum peltatum exhibiting anticancer activity against cells such as Hela, KB, and GLC4.
