Abstract:
The antibiotic heneicomycin (1), C44H62N2O11, was isolated from cultures of Streptomyces filipinensis as an amorphous yellow powder. Mass spectral and NMR analysis showed the compound to be a deoxy modification of aurodox (2), a member of the elfamycin antibiotic family. A marked change in mass spectral fragmentation compared to aurodox and 1H NMR couplings indicated the absence of the hydroxyl at position 30 of aurodox (position 3 of the tetrahydropyran).
