-
An inhibitor of the serine/threonine protein kinase B-raf (BRAF) and epidermal growth factor receptor (EGFR), with potential antineoplastic activity. BRAF/EGFR inhibitor BGB-283 selectively binds to and inhibits the activity of BRAF and certain BRAF mutant forms, and EGFR. This prevents BRAF- and EGFR-mediated signaling and inhibits the proliferation of tumor cells that either contain a mutated BRAF gene or express over-activated EGFR. In addition, BGB-283 inhibits mutant forms of the Ras proteins K-RAS and N-RAS. BRAF and EGFR are mutated or upregulated in many tumor cell types.
