    AXL1717 is a selective insulin-like growth factor-1 receptor (IGF-1R) inhibitor with IC50 of 1 nM.

    IC50 & Target

    IC50: 1 nM (IGF-1R)

    In Vitro

    In intact cells, AXL1717 efficiently inhibits IGF-1-stimulated IGF-1R, Akt (Ser 473) and Erk1/2 phosphorylation. AXL1717 specifically inhibits cell growth, and induces apoptosis in cultured IGF-1R-positive tumor cells[1]. AXL1717 synergistically sensitizes HMCL, primary human MM and murine 5T33MM cells to ABT-737 and ABT-199 by further decreasing cell viability and enhancing apoptosis[3]. AXL1717 and sorafenib synergistically suppress the proliferation and motility of hepatocellular carcinoma cells[4]

    In Vivo

    In SCID mice xenografted with human ES-1, BE, and PC3, AXL1717 (20 mg/kg/12 h, i.p.) causes complete tumor regression[1]. In the 5T33MM mouse model, AXL1717 also shows a marked antitumor activity, and causes a significant increase in survival[2].

    Kinase Assay

    Assay of IGF-1R-catalyzed substrate phosphorylation of pTG, using a 96-well plate tyrosine kinase assay kit, is performed. Recombinant epidermal growth factor receptor, immunoprecipitated IR from HEPG2, immunoprecipitated IGF-1R from P6 cells, and IGF-1R immunodepleted supernatant from P6 are used. After 30-min treatment of the receptors with the desired compounds in the kinase buffer [50 mM HEPES buffer (pH 7.4), 20 mM MgCl2, 0.1 MnCl2, and 0.2 Na3VO4], the kinase reaction is activated by addition of ATP. The phosphorylated polymer substrate is probed with a phosphotyrosine-specific monoclonal antibody conjugated to horseradish peroxidase, clone PT-66. Color is developed with horseradish peroxidase chromogenic substrate O-phenylenediamine dihydrochloride and quantitated by spectrophotometry (ELISA reader). IGF-1R tyrosine autophosphorylation is analyzed by a sandwich ELISA assay. Briefly, 96-well plates are coated overnight at 4°C with 1 μg/well of an antibody to IGF-1R β-subunit. The plates are blocked with 1% BSA in PBS Tween for 1 h, and then 80 μg/well of total protein lysate from the P6 cell line is added. The investigated compounds are added in tyrosine kinase buffer without ATP at room temperature for 30 min before kinase activation with ATP. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration

    AXL1717 is formulated in DMSO: vegetable oil, 10:1 (v/v).

    Four to 5-week-old pathogen-free SCID mice are used and housed within plastic isolators in a sterile facility. ES-1, BE, and PC3 cells (all proved to express IGF-1R), or R-v-src (IGF-1R negative) and P12 (overexpressing IGF-1 and IGF-1R), are injected s.c. at 107 cells/mice in a 0.2 mL volume of sterile saline solution. Immunocompetent Balb-c mice are injected with 107JC murine breast cancer cells per mouse in 0.15 mL volume of sterile saline solution. Experimental treatments with AXL1717 (20 mg/kg/12 h) are performed by daily i.p. injections of the compound in 10 μL volume of DMSO: vegetable oil, 10:1 (v/v). Control mice are treated with the vehicle only. Three animals are treated in each group. Tumor growth is measured every second day using vernier calipers, and the tumor volumes are calculated. The mice are carefully observed for the presence of side effects and are sacrificed at the end of the experiments for histological analysis of the lesions. A separate experiment on AXL1717-treated (systemically and locally) tumor-free mice, including histological analyses of various organs, confirms previous observations that AXL1717 appears to be nontoxic. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
