  • PubMed Abstract: 

    A direct binding screen of 100 000 sp(3)-rich molecules identified a single diastereomer of a macrolactam core that binds specifically to myeloid cell leukemia 1 (MCL1). A comprehensive toolbox of biophysical methods was applied to validate the original hit and subsequent analogues and also established a binding mode competitive with NOXA BH3 peptide. X-ray crystallography of ligand bound to MCL1 reveals a remarkable ligand/protein shape complementarity that diverges from previously disclosed MCL1 inhibitor costructures.
