Recursion and Enamine to Generate and Design Enriched Compound Libraries for Global Drug Discovery Industry

Screening libraries will leverage Recursion's MatchMaker tool to identify compounds across Enamine REAL Space predicted to bind to high-value targets.

KYIV, Ukraine and SALT LAKE CITY, Dec. 20, 2023 (GLOBE NEWSWIRE) -- Recursion (NASDAQ: RXRX), a leading clinical stage TechBio company decoding biology to industrialize drug discovery, today announced its partnership with Enamine, a world-renowned provider of novel molecules and contract research services, to generate enriched screening libraries with insights from Recursion’s protein-ligand interaction predictions spanning across Enamine’s massive library of 36 billion compounds.

Chris Gibson, CEO and Co-founder of Recursion, traveled to Kyiv to sign this partnership deal with Andrey Tolmachov, CEO and Founder of Enamine.

“I’m thrilled to announce this partnership as we continue to advance insights in chemical space using the power of relatable datasets and computational tools,” said Chris Gibson. “We believe combining one of the largest chemical libraries with our protein-ligand predictor tool, MatchMaker, will unlock the ability to generate more powerful compound libraries for drug discovery purposes.”

“Chemical space is limitless,” said Andrey Tolmachov. “While we have developed a reliable approach to synthetically accessible regions of chemical space, Recursion’s prediction technology has further highlighted the drug discovery-useful subregions with the molecules we can deliver.”

To begin the partnership, Enamine and Recursion will mutually agree upon up to 100 biological targets around which they will build screening libraries. From there, Recursion will utilize MatchMaker’s predicted protein-ligand interactions for Enamine REAL Space containing 36B compounds to design compound libraries enriched for molecules that are likely to bind to biological targets. Enamine may offer the resulting libraries to customers for purchase and will co-brand any libraries under both the Enamine and MatchMaker trademarks.

Recursion believes that these new libraries will be of interest to customers given the additional predictive insights via MatchMaker. The tool employs machine learning to evaluate the suitability of small molecules for specific protein binding pockets and is more scalable than traditional docking and physics-based interaction simulations. Similar to Recursion's Phenomics platform, MatchMaker's scalability affords a comprehensive view of biochemistry; it can predict binding activity for large quantities of molecules across the proteome. The predicted data can guide the selection of wet-lab experiments, helping to expedite progress across a diverse range of targets and chemical areas, and can act as a preliminary screening tool for more computationally intensive precision modeling techniques.

As part of the agreement, Recursion will receive a significant number of unique REAL compounds of Recursion’s choosing to augment its internal compound library, at no cost. Furthermore, Recursion will receive preferential pricing on any enriched screening libraries made available to Enamine customers as part of the collaboration.
