GSK046 (1000 nM; refresh every three days) reduces the recruitment of BET proteins to interferon (IFN) target genes following IFN-γ stimulation. GSK046 appears to more prominently affect the recruitment of BRD2 and BRD3 compared to BRD4[1].
GSK046 (0.1-10 μM) displays a more selective phenotypic fingerprint, particularly inhibiting the production of key pro-inflammatory mediators including Th17 cytokines in the B and T cell co-culture system[1].
GSK046 (0.01-10 μM; 72 hours) does not affect the proliferative activity of human primary CD4+ T cells but still inhibits the production of effector cytokines including IFNγ, IL-17A and IL-22[1].
GSK046 (0.005-10 μM; 48 hours) impairs macrophage activation following PMA stimulation, without impacting cellular viability[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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
