AXL1717
AXL1717 (Picropodophyllotoxin) is a selective inhibitor of IGF-1R with IC50 value rangs from 0.24-0.33 μM [1].
IGF-1R (type 1 insulin-like growth factor receptor) is a transmembrane receptor that activated by IGF-1 and plays an important role in cell growth and anabolic effects in adults. It has been reported that over-expression of IGF-1R is correlated with a variety of cancers and its inhibitors has been revealed to anti-cancer in clinical study [1] [2].
AXL 1717 is a potent IGF-1RTK inhibitor and has ability to inhibit tumor cells combined with HDAC inhibitor LBH589. When tested with 4 human myeloma cells (RPMI 8226, Karpas707, LP-1, and OPM-2) and 1 murine cell (5T33MM), AXL1717 treatment markedly decreased cell survival in a dose-dependent manner, arrested cell cycle in G2-M phase and induced cell apoptosis by inhibiting IGF-1RTK [1]. In four colon carcinoma cell lines (HT-29, HCT-116, DLD-1 and CaCO-2), AXL1717 treatment showed high ability to inhibit cell proliferation and migration in a dose-dependent manner [2].
In mouse model with 5TMM subcutaneous xenograft, administration of AXL 1717 (1.5 mg/d) resulted in a prolonged survival in combination with LBH (2.5 mg/kg/d) compared with control group [1].
AXL1717 has been tested to treat non-small cell lung cancer patients in a Phase I/II clinically [3].

Applications |
AXL1717 (0.05-0.5 μM, 48 h) dose-dependently inhibited cell growth, and induced apoptosis in cultured melanoma cells (FM 55 and SK-MEL-28), sarcoma cells (RD-ES), and the mouse cell line P6 (overexpressing IGF-1R). In P6 cells, AXL1717 (0.025-1 μM) efficiently inhibited IGF-1-stimulated IGF-1R, as well as Akt (serine 473) and Erk1/2 phosphorylation. AXL1717 (1 μM) synergistically enhanced the anti-myeloma activity of ABT-737. In OPM-2 and RPMI-8226 cells, AXL1717 (125-500 nM) synergistically enhanced ABT-737 and ABT-199 mediated apoptosis. AXL1717 (1 μM) inhibited DNA synthesis, chemotaxis, and VEGF secretion of 5T33MM cells. |
| Animal experiment [1-3]: | |

Animal models |
SCID mice xenografted with human ES-1, BE, and PC3; 5T33MM murine model; |
|
Dosage form |
Intraperitoneal injection, 20 mg/kg/12 h, 8–14 days |
|
Application |
In SCID mice xenografted with human ES-1, BE, and PC3, AXL1717 (20 mg/kg/12 h, i.p.) resulted in complete tumor regression. In 5T33MM murine model, AXL1717 (1.5 mg/kg, oral administration) showed a strong and significant reduction in BM plasmacytosis and serum M-protein levels. The combination of ABT-737 and AXL1717 (20 mg/kg, twice a day, intraperitoneally) did significantly and strongly prolong the overall survival. AXL1717 inhibited angiogenesis and prolonged the overall survival. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
