Scientists have harnessed the power of artificial intelligence (AI) to unearth a groundbreaking antibiotic capable of eliminating a lethal strain of superbug. By employing AI, researchers were able to narrow down an extensive pool of potential chemical compounds to a select few that could undergo laboratory testing. The outcome was the creation of a potent experimental antibiotic named abaucin, which will require further evaluation before its practical application.

Scientists from Canada and the United States assert that AI possesses the capacity to expedite the process of discovering novel drugs, exemplifying how artificial intelligence serves as a transformative force within the realms of science and medicine.

Countering the menace of superbugs, antibiotics serve as bacteria-killers. Nonetheless, the dearth of new antibiotics over the past decades has contributed to the escalating challenge of treating bacteria, which have gradually developed resistance to existing drugs. Alarming statistics indicate that more than a million individuals succumb annually to infections that defy treatment through antibiotics.

Focusing their efforts on Acinetobacter baumannii, one of the most problematic bacteria species, the researchers sought to address its capacity to infect wounds and cause pneumonia. Identified as a "critical" threat by the World Health Organization, this resilient bacterium can withstand multiple antibiotics, posing a significant problem in healthcare settings like hospitals and care homes where it can persist on surfaces and medical equipment.

The initial step in discovering a new antibiotic involved training the AI system. Researchers administered thousands of drugs with known chemical structures to Acinetobacter baumannii, meticulously observing their impact on the bacterium's growth and viability. The acquired data was then fed into the AI, enabling it to discern the chemical characteristics of drugs capable of combating the problematic bacterium.

Subsequently, the AI was tasked with evaluating a list of 6,680 compounds of uncertain effectiveness. The remarkable results, published in Nature Chemical Biology, revealed that the AI required a mere hour and a half to generate a shortlist of potential antibiotics. Of the 240 compounds tested in the laboratory, nine demonstrated promise, among which abaucin emerged as an exceptionally potent antibiotic.
