# Generative AI designs new antibiotics that kill drug-resistant gonorrhoea and MRSA

MIT's Collins lab (Cell, Aug 2025) used generative models to design more than 36 million candidate compounds from scratch. Lead NG1 kills multidrug-resistant Neisseria gonorrhoeae and DN1 kills MRSA, clearing skin infections in mice. Both act on bacterial membranes by novel mechanisms and are structurally unlike any known antibiotic.

## 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.
