Β?CATENIN/ B-CELL LYMPHOMA 9 PROTEIN?PROTEIN INTERACTION INHIBITING PEPTIDOMIMETICS

Paragraph 0167, (2020/11/03)
Disclosed herein is a series of helical sulfono-γ-AApeptides that mimic the binding mode of the α-helical HD2 domain of B-Cell Lymphoma 9 (BCL9). As disclosed herein, sulfono-γ-AApeptides can structurally and functionally mimic the α-helical domain of BCL9, and selectively disrupt β?catenin/BCL9 PPIs with even higher potency. More intriguingly, these sulfono-γ-AApeptides can enter cancer cells, bind with β?catenin and disrupt β?catenin/BCL PPI, and exhibit excellent cellular activity, which is much more potent than the BCL9 peptide. Furthermore, enzymatic stability studies demonstrated the remarkable stability of the helical sulfono-γ-AApeptides, with no degradation in the presence of pronase for 24 h, augmenting their biological potential.

The mimicry of protein tertiary structure by oligomers with unnatural backbones is a significant contemporary research challenge. Among common elements of secondary structure found in natural proteins, sheets have proven the most difficult to address. Here, we report the systematic comparison of different strategies for peptide backbone modification in β-sheets with the goal of identifying the best method for replacing a multi-stranded sheet in a protein tertiary fold. The most effective sheet modifications examined led to native-like tertiary folding behavior with a thermodynamic folded stability comparable to the prototype protein on which the modified backbones are based.
