Abstract:
2017 was the beginning of a groundbreaking collaboration. Enamine, a Ukrainian compound manufacturer, joined forces with BioSolveIT to pioneer what would soon become the world's most sophisticated journey in the expansive multi-trillion chemical space.
Since that time, not only has the core of Enamine's REAL concept expanded at an exponential rate (with other compound providers quickly joining the movement), but the computational tools designed to explore these vast molecular realms have also seen remarkable enhancements.
Collectively, compound providers now showcase nearly 8 trillion on-demand molecules. The "smaller" among these sets, referred to as "ultra-large libraries," can be probed using specialized software like Arthor, or even docked with DOCK5. However, these enumeration-based techniques are nearing their limits, especially with libraries extending beyond several tens of billions.
Our focus is on sidestepping enumeration methods as much as possible. This shift in thought has propelled drug research into domains previously deemed unreachable, exploring molecular sizes well beyond the trillions — all achievable on modest computer setups, delivering results within seconds for standard small molecule queries.
This presentation will delve into the latest topics:
- The coordinate-free "0D" FTrees algorithm, for rescaffolding.
- Distinctive 2D algorithms, rooted in Tanimoto-like metrics.
- 3D methods, exemplified by Chemical Space Docking and Fragment Growing.
These innovative techniques have undergone preliminary tests, or were co-developed in partnership with pharmaceutical entities. As a result, we have early applications and real-world success narratives to share. Of course, we won't shy away from discussing hurdles either.
The presentation will allow ample time for an in-depth Q&A session.
