Abstract
Two genetically engineered mutant strains of Streptomyces sp. MA6548 p roduced two FK506 analogs, 9-deoxo-31-O-demethylFK506 and 31-O-demethy lFK506. The structures were determined by a combination of NMR and mas s spectrometry. These compounds exhibited immunosuppressive and antifu ngal activities, albeit reduced, compared to FK506. Both compounds con tain a free hydroxyl group at C-31 for the synthesis of novel FK506 de rivatives.
