BEIJING, Jan. 9, 2025 /PRNewswire/ -- In a recent achievement, DP Technology's hit discovery platform RiDYMO® has successfully designed a cyclic peptide targeting β-catenin, a historically "undruggable" protein, in just two months. This innovative AI-driven approach combines advanced algorithms, physics simulations, and high-throughput experimentation to rapidly develop potential drug candidates for challenging targets. The platform's success with β-catenin, a key player in cancer development, demonstrates its potential to revolutionize drug discovery for previously intractable targets.
The Wnt/β-catenin pathway plays a crucial role in various biological functions and is implicated in multiple cancers[1-3]. Despite its importance as a therapeutic target[4-7], β-catenin has long been considered "undruggable" due to its flat protein surface[8-10]. The RiDYMO® platform overcomes this challenge by leveraging a vast library of over 10^12 cyclic peptides and macrocyclic molecules, incorporating both natural and non-natural amino acids.
Using the RiDYMO® platform, researchers rapidly designed and screened cyclic peptide molecules for β-catenin binding. The process involved:
The results were impressive, with 12 compounds showing strong inhibition of protein-protein interactions (IC50≤10 μM), a success rate of over 40%. One standout compound, designated as compound 24, effectively bound to β-catenin, disrupted its interaction with BCL9, and inhibited the Wnt/β-catenin signaling pathway.
Dr. Dongdong Wang, Co-President of DP Technology's Drug Discovery Unit, emphasized the platform's ability to tackle undruggable targets and rapidly design high-quality compounds. The RiDYMO® platform's success with β-catenin demonstrates its potential to accelerate the development of orally available cyclic peptide drugs, potentially transforming the pharmaceutical industry's approach to challenging targets.
This breakthrough in cyclic peptide design for β-catenin showcases the power of AI-driven drug discovery platforms in addressing previously intractable targets, potentially opening new avenues for cancer treatment and other therapeutic areas.
About the RiDYMO® Hit Discovery and Optimization Platform
RiDYMO® is a state-of-the-art hit discovery and optimization platform developed by DP Technology, leveraging the principles of AI for Science. It employs the proprietary Hermite® computational drug design software to elucidate the dynamics of "undruggable" targets and explores a broader chemical space encompassing small molecules, macrocycles, and cyclic peptides. By integrating advanced artificial intelligence, physics-based algorithms, and high-throughput experimentation, the platform excels in designing oral macrocyclic compounds and rapidly delivers innovative drug candidates.
As one of its core algorithms, Reinforced Dynamics (RiD)[4] has a significant advantage in the sampling efficiency of molecular dynamics simulation. By fully leveraging the high-dimensional representation capabilities of neural networks, RiD can efficiently capture dynamic conformational changes in complicated biomolecular systems. Previously, the core RiD algorithm of the platform was published in Nature Computational Science [11]. The study demonstrated that RiD could achieve a more comprehensive free energy surface within 1.86 μs, compared to 100 μs required by traditional MD methods, representing nearly a hundredfold increase in efficiency.
RiDYMO® has been successfully employed in various drug discovery programs, including the development of small molecule compounds for crucial targets such as c-Myc and GPX4, as well as other modalities such as cyclic peptides and ADCs.
