Abstract:
Pradimicin S was isolated from the culture filtrate of Actinomadura spinosa AA0851. NMR and MS analyses proved that pradimicin S is the 3'-O-(3''-O-sulfo-beta-D-glucopyranosyl) analog of pradimicin A, a new member of the pradimicin family of antibiotics. Stereochemical assignment was made by correlating pradimicin S with pradimicin L.
