Breakthrough in Cyclic Peptide Design for Cancer Treatment
Innovative Approaches to Target Undruggable Proteins
In a groundbreaking development, DP Technology has unveiled its advanced RiDYMO® platform, which has successfully engineered a cyclic peptide that targets ?-catenin, a protein historically deemed 'undruggable.' This remarkable achievement was accomplished in just two short months. The platform utilizes cutting-edge artificial intelligence, integrating sophisticated algorithms and high-throughput experimentation to forge new pathways in drug discovery for even the most challenging targets.
The Importance of ?-Catenin in Cancer Therapies
The Wnt/?-catenin signaling pathway is critically involved in numerous biological processes and plays a significant role in various types of cancers. Due to the protein's flat surface, it has been notoriously difficult to target with conventional therapeutic strategies. However, the RiDYMO® platform has risen to this challenge, leveraging a vast library of more than 10 trillion cyclic peptides and macrocyclic molecules. This library includes both natural and synthetic amino acids, providing a broad spectrum of potential drug candidates.
Advantages of the RiDYMO® Platform
With the RiDYMO® platform at the helm, researchers rapidly designed and screened cyclic peptides that could effectively bind to ?-catenin. The methodology included several key steps:
- Optimizing the ?-catenin structural model to enhance the binding site.
- Employing high-throughput screening to catalog cyclic peptides from the extensive library.
- Synthesizing and assessing 29 promising candidate molecules.
The findings were exceptional; out of the compounds tested, 12 demonstrated significant inhibition of protein-protein interactions, achieving an inhibition constant (IC50) of less than 10 ?M. One standout candidate, referred to as compound 24, exhibited a strong binding affinity to ?-catenin, disrupting its interaction with BCL9 and effectively blocking the Wnt/?-catenin signaling pathway.
The Future of Drug Discovery with AI
Dr. Dongdong Wang, Co-President of the Drug Discovery Unit at DP Technology, highlighted the platform’s remarkable capability to identify and design high-quality compounds targeting previously inaccessible proteins. The success with ?-catenin not only showcases the power of the RiDYMO® platform but also hints at a new era of developing orally available cyclic peptide pharmaceuticals. This technology may fundamentally reshape how the pharmaceutical industry approaches complex targets.
Potential Implications for Cancer Treatment
This innovative breakthrough in cyclic peptide design is expected to pave the way for new methods of treatment against various cancers, addressing the pressing need for effective therapies. The ability of the RiDYMO® platform to navigate complex biochemical landscapes could lead to new discoveries in cancer therapies and beyond.
