MedKoo CAT#: 205479

CAS#: 1195765-45-7 (free base)

Description: Dabrafenib, also known as GSK2118436 , is 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 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. On May 29, 2013, FDA approved this drug.
