Scientists have devised a free AI algorithm that they believe will make finding new medicines far more efficient.

can generate thousands of brand new, virtual drug in seconds for screening and testing. It can adapt to whatever "target" molecule is inputted, creating a library of drug candidates to test against this target, before optimizing the ones that work to make them still better. Available via Open Source, it can generate 10,000 molecules to fit a particular target in 0.75 seconds.

The team believes the software is immediately usable by scientists working in or in university research.

Dr. Olivier Pardo in the Department of Surgery & Cancer, who led the work, said, "We're very excited. Even though this is a fairly simple algorithm, it's far more efficient than anything more complex that has been tested or published out there, and will become very useful in AI-driven discovery for bespoke therapeutic targets."

The findings are in the Journal of Chemical Information and Modeling.
