[摘要]:The structure of mycolactone E (I), isolated from the frog pathogen Mycobacterium liflandii, was established via org. synthesis. Within the mycolactone family of metabolites, a structural variation has been seen only at the unsatd. fatty acid moiety thus far, and mycolactone E follows this observation. Interestingly, the abs. configuration of its unsatd. fatty acid matches that of the mycolactones from human mycobacteria, rather than the structurally more closely related mycolactone F from fish mycobacteria. |
