title: A new antiherpetic agent, AH-1763 IIa, produced by Streptomyces cyaneus strain no. 1763.
abstract: A new antiherpetic agent, AH-1763 IIa, was isolated from the culture broth of strain No. 1763 identified as Streptomyces cyaneus. It was purified through column chromatographies of Diaion HP-10 and silica gel. The structure was determined to be 11-hydroxy-5-methyl-2-(2-hydroxy-1-methylpropyl)-4H-anthraceno [1,2-b]pyran-4,7,12-trione by several spectroscopic experiments, that is a new antibiotic belonging to pluramycin-group.
