What are the advantages of Reaxys Predictive Retrosynthesis?
Reaxys Predictive Retrosynthesis is a best-in-class innovation in retrosynthesis for medicinal and synthetic chemistry. Getting from a desired novel molecule to an optimal synthesis route used to take considerable time, effort and expertise. With Reaxys Predictive Retrosynthesis, you will see improvements in:
Find routes to synthesize novel compounds and new, optimized routes for existing chemical compounds
Get the background literature that informed predicted synthesis routes and experimental procedures to decide what chemical compound to make and how to make it
Predict synthesis routes much faster than with other computer-aided retrosynthesis solutions; routes can be generated for novel compounds in 10 minutes
Determine commercial availability and pricing of starting materials as synthesis routes always terminate in purchasable starting materials
You can also integrate your own reaction data, building blocks or preferred vendors for more relevant results.
Elsevier and Pending.AI (PAI) collaborated to develop Reaxys Predictive Retrosynthesis based on foundational work published in Nature. We applied AI and machine learning to high-quality Reaxys data. And we double-blind tested predicted synthetic routes — proven to be scientifically sound and robust — with 45 organic chemists from around the world. The result is a solution that empowers chemists in:
- Drug discovery
- Fine chemicals
- Other chemical compound development
Reaxys Predictive Retrosynthesis uniquely leverages:
High-quality reaction data in Reaxys to train the predictive model — Deep learning technology has been trained on over 15 million reactions to auto-derive more than 400,000 reaction rules. These algorithmically extracted (versus hand-coded) rules are used to design and predict synthesis routes for known and novel molecules.
Three deep neural networks to auto-derive and apply reaction rules — The solution uses a model that incorporates deep neural networks trained on Reaxys data. The results are found using a Monte Carlo tree search approach to quickly discover promising candidate routes.
Self-learning from an ever-growing chemistry knowledgebase — The predictive model continuously improves as it gains intelligence from new data within Reaxys and the customer’s in-house research. This eliminates the negative impact of data siloes and unlocks learnings from successful and failed experiments.
How to use Reaxys Predictive Retrosynthesis
