AXL1717 (picropodophyllin, Picropodophyllotoxin, PPP) is a non-competitive, potent, and specific inhibitor of IGF-1Rα/β with IC50 of 1 nM. It exhibits little effect towards IR, FGFR, PDGFR and EGFR, and exerts no effects on microtubules and DNA topoisomerase II. Picropodophyllotoxin inhibits IGF1R autophosphorylation (IC50 ~ 1 nM), increases the fraction of cells in the G2/M phase and upregulates apoptosis.It also exhibits antiproliferative effects in multiple cancer cell lines (IC50 = 0.05 - 15 μM). In vivo,it has anticancer and antineovascularization activity.

|Incubation Time||3 days|
|Results||The cell proliferation ratios of the cells treated with afatinib, neratinib, or PPP compared with a control were 62.3%, 45.9%, and 54.1%, respectively.|

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
