Dabrafenib is a reversible kinase inhibitor with anticancer chemotherapeutic activity. This compound is selective primarily for mutant (V600E) B-Raf, but has also inhibited tumor growth in cells expressing other B-Raf mutants (V600K, V600D) and WT B-Raf. Dabrafenib is partially active against c-Raf as well. Dabrafenib is an ATP-competitive inhibitor that has been approved for clinical use in the treatment of unresectable or metastatic melanomas; it is also being examined for treatment of brain metastases and other cancers. This compound has a very high oral bioavailability.
