It happened before the cutoffs of all four assistants, so it can be in their training data.
Key facts
- >36 million compounds generated (fragment-based and unconstrained generation)
- NG1: active against multidrug-resistant N. gonorrhoeae; DN1: cleared MRSA skin infections in mice
- Novel membrane-targeting mechanisms; preclinical only
What happened
The team moved from screening existing libraries to generating new molecules, filtering tens of millions of designs down to a few synthesised leads.
Why it matters
It showed generative AI exploring chemical space beyond existing compound libraries for one of medicine’s most urgent needs.
