Herein are described peptide-based compositions for modifying Raf kinase protein Dimerization. These compositions, treatments, and methods of use are directed to peptides that display a binding affinity for the dimer interface of a Raf kinase protein, methods for modifying Raf kinase dimerization, and methods for inhibiting tumor growth. An embodiment of the disclosure is a peptide generated by modifying an ordered sequence chosen from SEQ ID NO: 1 which corresponds to amino acids 503-521 of B-Raf kinase. The peptides disclosed herein include a modification to an ordered sequence of amino acids derived from SEQ ID NO: 1 that can improve or otherwise alter binding affinity of the peptide to the dimer interface.
