Structural requirements for STAT3 binding and recruitment to phosphotyrosine ligands

摘要

Inhibitors of Stat3 are disclosed, including small molecules and peptide mimetic inhibitors. Specific Stat3 inhibitors of the invention are useful as beta-turn mimetics. Also disclosed are pharmaceutical compositions of the Stat3 inhibitors of the invention, and methods for using the compounds of the invention to inhibit growth of a cell or to inhibit protein-protein interactions modulated by SH2 domains. Methods of screening for Stat3 inhibitors are also provided.
