Mutasynthesis and Antibiotic Activity of Mupirocin Analogues. [PDF]

open access: yesChembiochem
A mutasynthetic strategy was developed to prepare pseudomonic acid analogues, and their antimicrobial activities were evaluated against five bacterial strains. Feeding studies with mutant strains of Pseudomonas fluorescens revealed that C7‐desepoxy‐PA‐B was metabolised to C7‐PA‐C with loss of the 8‐hydroxyl group, but no fatty acid chain extension ...
