== Publication Abstract from PubMed ==

B-cell lymphoma 6 (BCL6) is a transcriptional factor that expresses in lymphocytes and regulates the differentiation and proliferation of lymphocytes. Therefore, BCL6 is a therapeutic target for autoimmune diseases and cancer treatment. This report presents the discovery of BCL6-corepressor interaction inhibitors by using a biophysics-driven fragment-based approach. Using the surface plasmon resonance (SPR)-based fragment screening, we successfully identified fragment 1 (SPR KD = 1200 muM, ligand efficiency (LE) = 0.28), a competitive binder to the natural ligand BCoR peptide. Moreover, we elaborated 1 into the more potent compound 7 (SPR KD = 0.078 muM, LE = 0.37, cell-free protein-protein interaction (PPI) IC50 = 0.48 muM (ELISA), cellular PPI IC50 = 8.6 muM (M2H)) by a structure-based design and structural integration with a second high-throughput screening hit.
