Story summary

Researchers from the University of Warwick and Monash University have discovered a new antibiotic, pre-methylenomycin C lactone, effective against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE).
The compound is found in the well-studied bacterium Streptomyces coelicolor and is over 100 times more potent than methylenomycin A.
In lab tests, bacteria did not develop resistance to pre-methylenomycin C lactone.
Pre-clinical testing is planned to confirm its efficacy and safety amid antimicrobial resistance that currently claims about 1.1 million lives annually.
The discovery points to a new approach to antibiotic development by exploring intermediate compounds in antibiotic production.
