Bioactive Compounds from Mangrove-Associated Fungi as Leads Against ESKAPE Pathogens
Abstract
The rapid emergence and dissemination of antimicrobial resistance (AMR) among bacterial pathogens, particularly the ESKAPE group (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.), represents one of the most pressing global public health challenges, contributing to increased morbidity, mortality, and healthcare costs. The limited development of new antibiotic classes over the past two decades has intensified the search for structurally novel antimicrobial agents and adjuvants capable of overcoming multidrug resistance. Natural products continue to serve as an invaluable source of anti-infective drug leads owing to their remarkable structural diversity and broad spectrum of biological activities. Mangrove ecosystems, located at the interface of terrestrial and marine environments, harbor highly diverse microbial communities, including fungi that have evolved under extreme environmental conditions and produce a wide range of unique secondary metabolites. Beyond their ecological significance, mangrove-associated fungi have emerged as prolific producers of bioactive compounds with promising antibacterial activity against multidrug-resistant pathogens. This review comprehensively summarizes recent advances (2018-2026) in the discovery of antibacterial metabolites from mangrove-associated fungi active against ESKAPE pathogens, which discusses their structural diversity, reported antimicrobial…
