Researchers designed potent cyclic peptide inhibitors targeting the YAP-TEAD protein-protein interaction crucial for cancer growth. These novel inhibitors show significant promise for treating YAP-involved cancers.
Area of Science:
- Oncology
- Molecular Biology
- Drug Discovery
Background:
- The YAP-TEAD protein-protein interaction (PPI) is a key driver in various YAP-involved cancers.
- Inhibiting this interaction presents a therapeutic strategy for cancer treatment.
Purpose of the Study:
- To design and synthesize potent cyclic peptide inhibitors of the YAP-TEAD PPI.
- To develop novel therapeutics for YAP-associated malignancies.
Main Methods:
- Truncation studies and alanine scanning of YAP interface 3 peptide.
- Chemical modifications including disulfide bridge formation and macrocyclization.
- In vitro biochemical assays to determine inhibitory activity (IC50) and binding affinity (Kd).
Main Results:
- Identified YAP(84-100) as a weak peptide inhibitor (IC50 = 37 μM).
- Optimized peptide structure through mutation (D94A), disulfide bridge, and macrocyclization.
- Developed Peptide 17 with significantly enhanced inhibitory activity (IC50 = 25 nM) and strong binding affinity (Kd = 15 nM) to TEAD1.
Conclusions:
- Novel cyclic peptides effectively inhibit the YAP-TEAD interaction.
- Engineered peptides demonstrate potent anti-cancer potential for YAP-driven tumors.
- Optimized inhibitors represent promising drug candidates for cancer therapy.
