Abstract

A FK506 analogue containing a non-natural starter unit was obtained through mutasynthesis by feeding cultures of Streptomyces sp. KCTC 11604BP fkbO deletion mutant with 3-cyclohexene-1-carboxylic acid. The structure of the new compound, 32-dehydroxy-FK506, and its biological activities were determined.
