flag Scientists found a potent antibiotic intermediate in soil bacteria that fights drug-resistant infections without triggering resistance.

flag Chemists from the University of Warwick and Monash University have discovered pre-methylenomycin C lactone, a biosynthetic intermediate of methylenomycin A, which is over 100 times more effective than its parent compound against drug-resistant Gram-positive bacteria like MRSA and VRE. flag The compound showed no detectable resistance development during testing, unlike vancomycin, and was found in Streptomyces coelicolor, suggesting nature may produce potent antibiotics as intermediates. flag A scalable synthesis method has been developed, enabling further study. flag The discovery offers a new strategy for antibiotic development amid rising antimicrobial resistance, a major global health threat.
