    • note
    • iso-Archazolid B (6) can be detected directly in the fermentation broth before isolation, which suggests that it presents an authentic natural product and not an isolation artifact derived from archazolid B. Isomerization during extraction or detection likewise seems highly unlikely, as this has never been detected for the archazolid family under such conditions (see refs 16, 21-27). A related double-bond migration has been observed only for a ring-opened derivative but not for the macrocyclic metabolites. Also, this isomerization has occurred only under basic conditions but not under the neutral pH values present during fermentation (see ref 23). Therefore an isomerization is much more likely before ring-closure, i.e., during the biosynthesis of isoarchazolid B.
