Solubility (25°C)* In vitro DMSO 100 mg/mL (192.47 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG 300 5%Tween80 50% ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/mL clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify; add 50 μL of Tween-80 to the above system, mix evenly to clarify; Then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Dabrafenib is a mutant BRAFV600E specific inhibitor with IC50 of 0.7 nM in cell-free assays, with 7- and 9-fold less potency against B-Raf(wt) and c-Raf, respectively.
Targets
B-Raf (V600E) [3]
(Cell-free assay)		 B-Raf [3]
(Cell-free assay)		 C-Raf [3]
(Cell-free assay)
0.7 nM 5.2 nM 6.3 nM
In vitro

Dabrafenib is selective for Raf kinase, with 400 fold selectivity towards B-Raf over 91% of the other kinases tested. Dabrafenib inhibits B-RafV600E kinase, leading to decreased ERK phosphorylation and inhibition of cell proliferationby an initial arrest in the G1 phase of the cell cycle in cancer cells that specifically encode the mutation for B-RafV600E. [1]
In vivo

Dabrafenib (orally administrated) inhibits the growth of B-RafV600E mutant melanoma (A375P) and colon cancer (Colo205) human tumor xenografts, growing subcutaneously in immuno-compromised mice. [1]
