SB-405483 (2.5-25 μM) binds the recombinant human CRBN/DDB1 complex with a binding potency of 25 ± 0.9 μM and exhibits highly synergistic binding with the lenalidomide-Alexa647 probe[1].
SB-405483 (25 μM) potentiates the binding of multiple orthosteric CRBN ligands to the recombinant human CRBN/DDB1 complex, as shown by 8.96- to 43.7-fold decreases in their IC50 values, with no effect on mezigdomide binding[1].
SB-405483 (0.1-25 μM; 1 h) stabilizes endogenous CRBN in MM.1S cells in a dose-dependent manner, with enhanced stabilization when co-treated with Lenalidomide (HY-A0003)[1].
SB-405483 (0.1-10 μM) inhibits autoubiquitination of endogenous Flag-tagged CRBN in HEK293T cells in a dose-dependent manner[1].
SB-405483 (10 μM; 0.5-24 h) potentiates DEG-47-mediated degradation of endogenous CK1α in MOLM-13 cells[1].
SB-405483 (10 μM; 24 h) potentiates DEG-47-mediated degradation of Wee1 in A2780 Wee1-HiBiT cells and MOLM-13 cells[1].
SB-405483 (10 μM; 24 h) inhibits DEG-47-mediated degradation of IKZF1/3(ZF2)-GFP and IKZF2(ZF2)-GFP in HEK293T reporter cells after 24 h[1].
SB-405483 (10 μM; 24 h) modestly potentiates DEG-47-mediated degradation of SALL4(ZF1,2)-GFP in U937 Cas9 cells[1].

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.
