Physics+AI-Guided Design and Plate-Based Synthesis Unlock >10¹² Cyclic Peptidomimetics for Cell-Permeable Inhibitor Discovery
Company Description
Cyclic peptidomimetics occupy the sweet spot between small molecules and biologics, combining high target affinity with proteolytic stability and intrinsic cell penetration. However, their vast chemical space presents significant challenges for discovery. To address this, we (Atombeat Inc.) introduce RiDYMO.PepTx, a physics- and AI-guided platform that enables rational in silica design within an in silico library of over 10¹² macrocycles, constructed from more than 500 natural and unatural amino acids. The platform integrates drug-likeness and permeability neural networks to prioritize candidates for rapid synthesis and testing.
We applied RiDYMO.PepTx to two contrasting targets: thrombin, where 8 of 89 compounds showed greater than 50% inhibition, and β-catenin, where 11 of 29 compounds demonstrated cellular IC₅₀ values below 10 µM. One β-catenin lead was confirmed to disrupt the BCL9 interaction, exhibit passive permeability, and inhibit Wnt signaling.
All hits emerged from a single design-make-test cycle, demonstrating how AI-enhanced, physics-informed design—coupled with parallel synthesis—can accelerate discovery and unlock challenging macrocyclic space.
