Structure of a Novel Disulfide of 2-(N-Acetylcysteinyl)amido-2-deoxy-α-D-glucopyran-osyl-myo-inositol Produced byStreptomycessp.

Abstract
A novel dimer of an inositol glycoside was isolated from the mycelial extracts of Streptomyces sp. AJ 9463. Its structure was assigned as a disulfide of 2-(N-acetyl-L-cysteinyl)amido-2-deoxy-alpha-D-glucopyranosyl-(1-->1)-1D- myo- inositol (1).
