In vitro

2-D08 inhibits sumoylation by preventing transfer of SUMO from the UBC9-SUMO thioester to the substrate[2]. It decreases the ratio of p-Axl to t-Axl in a dose-dependent manner. Suppression of Axl kinase activity by 2D08 disrupts the cytoskeleton and actin filaments with re-organization at cellular junctions as shown by F-actin staining with phalloidin and increased expression of ZO-1 at cellular junctions. It also promotes translocation of β-catenin to cellular junctions and causes an upregulated E-cadherin. 2D08 significantly decreases the migration ability in lung multi-potent cell lines in a dose-dependent manner[1].

Protocol (from reference)

Kinase Assay:

[1]

  • In Vitro Biochemical Kinase Assay:

    IC50 values of the Axl kinase inhibitor (2D08) are determined using kinase-mediated phosphorylation of poly-GAT by AlphaScreen luminescence detection technology. The inhibitor is tested at eight points of dilution in duplicate.

Cell Research:

[1]

  • Cell lines: Human lung multi-potent cells at passage 5
  • Concentrations: 0.1, 1, 10 μM
  • Incubation Time: 3 h (+ 16 h)
  • Method:

    Human lung multi-potent cells at passage 5 are plated at a density of 250 000 cells per well in six-well plates with growth medium. After 24 h, multi-potent cells are incubated with DMEM+0.5% BSA+penicillin/streptomycin containing 0.1% DMSO (vehicle) or 2D08 (0.1, 1, 10 μM) for 3 h in a humidified 5% CO2 incubator at 37℃. These cells are trypsinized and seeded at 20 000 cells per well in three replicates on 12-well cell culture transwell inserts with 8 μm pore size with DMEM+0.5% BSA+penicillin/streptomycin. Lower transwell chambers contained DMEM+10% FBS+penicillin/streptomycin are used to allow cells to migrate. 0.1% DMSO or 2D08 is added to corresponding upper and lower transwell chambers. After 16 h, non-migrated cells are removed by cotton swabs. Migrated cells are fixed with 4% PFA, permeabilized with methanol and stained with crystal violet. The field-images per transwell are taken by an inverted light microscope.

Animal Research:

[3]

  • Animal Models: α2−/− mice (Eight- to 10-week-old mice)
  • Dosages: 30 μM (10 μl)
  • Administration: injected on one hemisphere near the hippocampal area
