title: Structural investigation of the antibiotic sporaviridin. X. Isolation and characterization of components of N-acetylsporaviridins.
abstract: Isolation and characterization of the major components of N-acetylsporaviridins, a derivative obtained by treatment of sporaviridins with acetic anhydride in methanol were carried out. The isolation procedure as shown in Scheme 1 gave successfully six components whose molecular weights are all about 2,200. Each component was suggested to be a glycosidic compound consisting of a macrocyclic lactone, one of viridopentaoses, a D-glucose and an N-acetyl-L-vancosamine by various spectral data.
