ChEBI: Dabrafenib is an organofluorine compound and antineoplastic agent, used as its mesylate salt in treatment of metastatic melanoma. It has a role as an antineoplastic agent, a B-Raf inhibitor and an anticoronaviral agent. It is a sulfonamide, an organofluorine compound, a member of 1,3-thiazoles and an aminopyrimidine.NCI Thesaurus (NCIt): Dabrafenib 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 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.
