Dabrafenib (GSK2118436) is a selective and potent B-Raf inhibitor. The compound inhibits mutant B-RafV600E and B-RafV600K with IC50 values of 0.6 nM and 0.5 nM, respectively, and is less effective at inhibiting wild-type B-Raf and C-Raf (IC50 = 3.2 nM and 5.0 nM, respectively) (1). Dabrafenib (GSK2118436) has also been shown to inhibit cell proliferation and ERK signaling in melanoma cell lines carrying the B-RafV600R and B-RafV600D mutations as compared to wild-type B-Raf (2). The specificity of this compound makes it a useful reagent when studying metastatic melanoma with B-Raf mutations (3).

This product has applications to SARS-CoV-2 research into the mechanisms of the Novel Coronavirus, which has caused the COVID-19 pandemic.
