Picropodophyllotoxin 是一种环木脂素生物碱，存在于五月树 (Podophyllum peltatum) 中，是一种具有潜在抗肿瘤活性的胰岛素样生长因子 1 受体 (IGF1R) 的小分子抑制剂。它特异性抑制 IGF1R 的活性并下调细胞表达，而不干扰其他生长因子受体的活性，例如胰岛素受体、表皮生长因子、血小板衍生生长因子、成纤维细胞生长因子和肥大/干细胞生长因子 (KIT) ）。该药剂在抑制肿瘤细胞增殖和诱导肿瘤细胞凋亡方面显示出有效的活性。 IGF1R 是一种在多种人类癌症中过度表达的受体酪氨酸激酶，在多种癌细胞的生长和存活中起关键作用。

Picropodophyllin 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. Picropodophyllin 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.
