The pain relieving effects of drugs like ibuprofen are well known. But ibuprofen and its relatives, known as nonsteroid anti-inflammatory drugs, may someday have another use: as antibiotics 1. Researchers tested three anti-inflammatory drugs: bromfenac, used in eye drops; and carpfonen and wedeproofen, both for treating conditions like arthritis 2 in dogs. The investigators 3 found that all three drugs bind 4 to something called the DNA 5 clamp(?) in bacteria. That clamp is essential to repairing and replicating 6 DNA. By jamming it, the painkillers 7 can actually kill live cola(?) in a test tu... at least. The finding appears in the journal Chemistry & Biology. Study author Ahron Oakley of Australia University of Wollengong says we still need clinical trials to tell if this trick holds true in humans. But this study is a first step. "This is to alert a lot of technicians to the fact some of the nonsteroidal ... they using may have this targeted effect." It gives drug developers, like Oakley and his colleagues, a whole new way to attack antibiotic-resistant bacteria.
