Artificial intelligence was employed by researchers to find a novel antibiotic that can destroy dangerous "superbug" germs.
AI assisted in eliminating thousands of potential substances in order to concentrate on a select few that could be evaluated in a lab.
As a result, the potent experimental antibiotic "abaucin" was discovered. However, it still needs to undergo additional testing before it can be put to use.
According to Canadian and American researchers, artificial intelligence can considerably advance the development of novel pharmaceuticals.
The decision is the most recent illustration of how artificial intelligence techniques have the potential to significantly alter science and medicine.
Stop the activity of "superbug" bacteria
Although antibiotics can kill germs, there has been a long-standing drug shortage, making it more challenging to treat bacterial illnesses as they become resistant to antibiotics.
According to statistics, a million or more individuals per year pass away from diseases brought on by germs that are hard to treat with antibiotics.
The Acinetobacter baumannii bacteria, which may infect wounds and cause pneumonia, was the focus of the researchers' attention.
They are one of three superbug varieties that the World Health Organisation has identified as posing a "serious" threat, despite the fact that you may not have heard of them.

Since it can thrive on surfaces and medical equipment, this bacteria frequently evades the effects of many antibiotics, which is a problem in hospitals and nursing homes.
Bacteria are "the most common enemy," according to McMaster University doctor Jonathan Stokes, because cases where they are "resistant to almost every antibiotic" are "already common."
artificial intelligence
The researchers painstakingly tested thousands of medications known for their specific chemical composition on Acinetobacter baumannii to see which species could slow down or kill this bacterium before turning to artificial intelligence training to find a novel antibiotic.
In order for the AI to learn the chemical characteristics of medications that could combat disease-causing germs, researchers gave it this data.
The scientists then gave the AI a list of 6,680 chemical compounds whose potency was unknown and left it to work. The findings, which were published in the journal Nature Chemical Biology, revealed that the AI required approximately one and a half hours to choose a shortlist.
Nine possible antibiotics were discovered by the researchers after testing 240 species in the lab, including the extremely effective antibiotic "abaucin".

Studies in the lab revealed that this antibiotic might heal mice with infected wounds and could eradicate samples of the superbug "A. baumannii" in some individuals.
Despite this, Stokes said, "It's time to get started."
The next step is to create a medicine in the lab and then test it in clinical settings. It is anticipated that it would take until 2030 before the first antibiotics, aided by artificial intelligence, are ready to be prescribed to patients.
It is odd that this experimental antibiotic only worked on the strain of bacteria known as "A. baumannii" and had no impact on any other sorts of bacteria.
The accuracy of the antibiotic "Abucin" will, according to researchers, make it harder for bacterial resistance to develop with fewer adverse effects than other antibiotics that kill all germs without discrimination.
In theory, AI could screen through tens of millions of potential chemical molecules, an action that would be practically challenging to complete by hand.
According to Stokes, "artificial intelligence increases rates (outcomes) and lowers cost, allowing us to find these new classes of antibiotics that we sorely need.
In 2020, researchers employed coliform bacteria to test the concepts of AI-assisted antibiotic discovery; however, they have since applied this knowledge to concentrate on the most harmful species. Next, they intend to study Pseudomonas aeruginosa and Staphylococcus aureus.
"This result supports the hypothesis that artificial intelligence can accelerate and enhance the scope of our research on new antibiotics," Massachusetts Institute of Technology professor James Collins stated.
He continued, "I am thrilled that this work demonstrates that we may utilise AI to assist combat infections like A. baumannii.
