Researchers at McMaster University and Stanford University have collaborated to create a revolutionary generative artificial intelligence model capable of designing billions of innovative antibiotics quickly and inexpensively. The urgent need for new antibiotic treatments due to the global spread of drug-resistant bacteria has prompted this groundbreaking development.
Published in Nature Machine Intelligence, the study unveils the new AI model, SyntheMol, designed to combat Acinetobacter baumannii, a highly dangerous antibiotic-resistant bacterium identified by the World Health Organization. A. baumannii poses a significant threat, causing pneumonia, meningitis, and severe infections that can be life-threatening, with limited treatment options currently available.
The researchers utilized a library of 132,000 molecular fragments, each unique in nature, which were combined using 13 chemical reactions to generate 30 billion potential molecules with promising antibacterial properties. Through an additional AI model predicting toxicity, six non-toxic molecules with potent antibacterial activity against A. baumannii were identified.
SyntheMol not only creates novel antibiotic candidates but also provides the recipe for their synthesis, a critical advancement as chemists typically lack this information when working with AI-designed molecules. This innovative approach shows promise in developing a robust pipeline of antibiotics quickly and affordably, essential in combating evolving bacteria and antibiotic resistance.
The research was supported by the Weston Family Foundation, the Canadian Institutes of Health Research, and Marnix and Mary Heersink, highlighting the importance of partnerships in advancing antibiotic discovery. The development of SyntheMol represents a significant step forward in addressing the pressing need for new antibiotics in the fight against drug-resistant bacteria.
