超强抗生素，被意外发现！

Core Insights - A new antibiotic, pre-penicillin C lactone, has been discovered during the production process of a commonly used antibiotic, penicillin A, which shows over 100 times higher antibacterial activity against various Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus [1][2] Group 1 - The research was conducted by Monash University in collaboration with the University of Warwick, highlighting the potential of intermediate compounds in antibiotic synthesis [1] - The discovery provides a new model for identifying and testing intermediates in the synthesis pathways of various natural compounds, which may lead to the development of new antibiotics to combat antibiotic resistance [1]
