Common NameLugdunin
DescriptionLugdunin is a thiazolidine-containing antimicrobial peptide classified as a natural product in the chemical class of peptides. It is produced by the bacterium Staphylococcus lugdunensis, which has gained attention due to its emerging role as a coagulase-negative Staphylococcus (CoNS) pathogen. The chemical structure of lugdunin allows it to exhibit antibacterial activity primarily against gram-positive bacteria, as evidenced by studies that evaluated its effects under various conditions. Specifically, optimal conditions for lugdunin activity were identified at pH 7.5 with a 72-hour incubation period, leading to antimicrobial effects against several strains, including Staphylococcus aureus and Enterococcus faecium (PMID:40986964 ). In addition to its antibacterial properties, the study revealed distinct susceptibility phenotypes among lugdunin-nonproducing S. lugdunensis strains, highlighting the complexity of its interactions within microbial communities (PMID:40986964 ). Further research has also explored multi-cationic derivatives of lugdunin, expanding its antimicrobial spectrum to include both gram-positive and gram-negative bacteria (PMID:40848518 ). Overall, lugdunin represents a significant chemical entity with potential applications in combating antibiotic-resistant infections.
