NCIt definition : The mesylate salt form of dabrafenib, an orally bioavailable inhibitor of B-raf (BRAF)
protein with potential antineoplastic activity. Dabrafenib selectively binds to and
inhibits the activity of B-raf, which may inhibit the proliferation of tumor cells
which contain a mutated BRAF gene. B-raf belongs to the raf/mil family of serine/threonine
protein kinases and plays a role in regulating the MAP kinase/ERKs signaling pathway,
which may be constitutively activated due to BRAF gene mutations.;
