2-D08 is a cell permeable, mechanistically unique inhibitor of protein SUMOylation. 2-D08 also inhibits Axl with an IC₅₀ of 0.49 nM.

IC50: 0.49 nM (Axl)^[2]

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].

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].

Mice^[3]

Eight- to 10-week-old mice (both male and female) are used for the study. A 5 cm-long glass pipette is buffered with Mineral Oil and then attached to the injection apparatus to take up 10 μL of 2-D08 (30 μM) or NaCl^[3].
