Story summary

Scientists from the University of Warwick and Monash University discovered pre-methylenomycin C lactone, a new antibiotic over 100 times stronger than methylenomycin A.
The compound emerged during methylenomycin A's natural production and shows promise against MRSA.
Bacteria did not develop resistance to pre-methylenomycin C lactone, suggesting future potential.
Professor Greg Challis said the discovery was unexpected and noted a new approach to antibiotic research, with pre-clinical testing next.
