Scientists Identify Madecassic Acid as Potential Solution to Drug-Resistant Bacteria
Researchers at the University of Kent, in collaboration with University College London, have discovered that madecassic acid, a compound derived from the plant Centella asiatica, shows promise in combating antibiotic-resistant bacteria. This discovery is significant as drug-resistant infections pose a growing global health threat, with projections estimating 39 million deaths from antimicrobial resistance between 2025 and 2050. The study, published in RSC Medicinal Chemistry, highlights madecassic acid's ability to inhibit the growth of antibiotic-resistant E. coli by targeting the cytochrome bd complex, a protein system crucial for bacterial respiration and survival. This system is absent in humans and animals, making it an ideal target for new antimicrobial treatments. The research also explored modified versions of madecassic acid, which demonstrated even stronger antibacterial effects.
