Need to screen 100,000 molecules for synthetic accessibility?
We’ve got you covered.

Synthetic Accessibility Score

  • Estimate synthetic accessibility using actual synthesis pathways, not complexity heuristics
  • Use different complexity measures such as number of steps, route robustness, price of starting materials (and more)
  • Screen up to 5,000 compounds per hour in our standard plan (the throughput can be tailored to your needs. Coming soon: 50k/h with the same computational resources.

The target on the left has a pretty straightforward synthesis, whereas the one on the right poses a significant challenge due to an unusual moiety. Our technology allows distinguishing between them extremely quickly.

The dots represent compounds arranged spatially by Morgan fingerprint similarity. Colouring corresponds to target difficulty assessed by Molecule.one SAS score. Our score finds easy to synthesize compounds in each cluster.

Our approach combines best-in-class, interpretable
AI with excellent user experience. Reach out to us today
