Hi everyone! – We’re Piotr, Weronika, and Adam, a team of biochemists and evolutionary biologists from the University of Oxford on a mission to make the next-generation of antibiotics.
Current antibiotics stop working because bacteria evolve resistance to them. Our approach leverages co-evolutionary protein-protein interaction datasets combined with AI to forecast bacterial mutations and create ‘future-proof’ antibiotics, addressing antibiotic resistance before it develops. This changes the game for how frequently we’ll need to make new antibiotics and how long our new antibiotics will be able to treat patients.
Let's get into more detail:
Antibiotic resistance is a looming global health crisis:
Traditional trial-and-error discovery cannot compete with bacteria's ability to mutate and acquire resistance genes. Our evolutionary datasets and AI will allow us to stay one step ahead of bacteria. We don’t react, we anticipate:
You might wonder whether bacteria would eventually be able to mutate in other ways around our antibiotics. Well, yes, they could, but our approach forces all the escape mutations to be extremely costly. In fact, so costly that the bacteria wouldn’t survive. How?
Our experiments are like running a battle simulation hundreds of times to find enemies’ weak points. This means that we can create detailed maps of the co-evolutionary landscapes of bacteria and our antibiotics so that we can ultimately engineer medicines with a low propensity for resistance emergence.
We then engineer our antibiotics for stability and safety inside the human body using a suite of protein AI models (both diffusion and language model-based). This engineering means our antibiotics 1) only target pathogenic bacteria and not human cells or microbiomes and 2) have the potential to be given as a single dose – reducing the amount of monitoring that doctors have to do on patients. This is in contrast to current antibiotics, which can have human cell toxicity, disrupt microbiomes, and have to be dosed every few hours.
Our blueprints have the potential for:
Are you as excited as we are about making future-proof antibiotics?
