PRADIMICIN S, A NEW PRADIMICIN ANALOG

II. ISOLATION AND STRUCTURE ELUCIDATION

抄録

Pradimicin S was isolated from the culture nitrate of Actinomadura spinosa AA0851. NMR and MS analyses proved that pradimicin S is the 3'-O-(3"-O-sulfo-β-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.
