Adxanthromycins A and B, New Inhibitors of ICAM-1/LFA-1 Mediated Cell Adhesion Molecule from Streptomyces sp. NA-148. II. Physico-chemical Properties and Structure Elucidation.
sp. NA-148. The molecular formula of adxanthromycins A and B were determined as C42H40O17 and C48H50O22, respectively by FAB-MS and NMR spectral analyses, and the structures of both compounds were elucidated to be a dimericanthroneperoxide skeleton containing alpha-D-galactose by various NMR spectral analyses and chemical degradation.

Oxanthromicin, an antibiotic isolated from an Actinomadura sp. SCC 1646 fermentation broth, has been assigned a noveldimericperoxidestructure based on chemical transformations and spectral data, and by a single-crystal X-ray analysis of a tetramethyl derivative.
