Biological Activity

Axl |
2-D08 inhibits sumoylation by preventing transfer of SUMO from the UBC9-SUMO thioester to the substrate[1]. 2-D08 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[2].

The expression levels of TGF-β/SMAD and HIF-1 signaling pathways-related proteins, including Col III, Smad2, Smad3, Smad4 and HIF-1α are measured by western blotting in HFFs and HKFs. The band intensity ratio of the TGF-β/SMAD and HIF-1 signaling related protein to reference protein is significantly decreased in the 2-D08 group.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol
Human lung multi-potent cells at passage 5 are incubated with DMEM+0.5% BSA+penicillin/streptomycin containing either 0.1% DMSO (vehicle) or 2D08 (10 μM) on Permanox culture slides for 6 days. Cells are fixed with 4% PFA for 30 min and then blocked and permeabilized with 10% goat serum and 0.3% Triton-X 100 in PBS for 30 min[2].
