Inhibitors of BRAF dimers using an allosteric site

Abstract

FDA-approved RAF inhibitors poorly inhibit BRAF dimers, which limits their clinical efficacy in tumors expressing BRAFV600E mutant monomers. Here the authors identify FDA-approved Ponatinib as an effective inhibitor of BRAF monomers and dimers and designed PHI1, an inhibitor with a unique mode of action and selectivity for oncogenic BRAF dimers.
