Researchers have identified a potent new antibiotic compound using artificial intelligence. The antibiotic can kill very dangerous bacteria. According to a study published in the journal Cell, the compound successfully removed deadly strains of bacteria in mice which are resistant to all known antibiotics.
    The researchers say this is the first time that artificial intelligence has been used to find a powerful new antibiotic molecule. Why does this matter? The answer is antibiotic resistance. This happens when bacteria develop the ability to survive the medications designed to kill them. Antibiotic resistance is a serious threat to health and the problem is growing. This makes finding new antibiotics very important. However, in recent decades, very few have been developed, and those that have tend to be very similar to drugs already available. The searches also tend to only focus on a narrow spectrum of chemical compounds, but this is where artificial intelligence comes in. Why? To find new drugs, scientists screen molecules to predict how effective they might be. Typically, such screening is done by humans in the lab, which is both costly and slow. Artificial intelligence is different. It’s fast, and it can process a high volume. It can screen hundreds of millions of compounds to identify a few interesting candidates that require experimental testing. Artificial intelligence is also able to predict if compounds are likely to be toxic. Some experts assert that this work signifies a paradigm shift in antibiotic discovery. It could change drug discovery more generally.
