WebJul 1, 2024 · Darobactin A (DAR) is a ribosomally synthesized and post-translationally modified peptide (RiPP) antibiotic, which was initially identified from bacteria belonging to the genus Photorhabdus. In addition, the corresponding biosynthetic gene cluster (BGC) was identified and subsequently detected in several bacteria genera. DAR represents a highly ... WebNov 22, 2024 · Darobactin kills several gram-negative bacteria in culture, including E. coli, Klebsiella, Shigella, and Salmonella. They also tested the compound in mice. A single dose protected mice infected with E. coli, K. pneumoniae and P. aeruginosa, with no toxicity, while untreated animals died within 24 hours.
