摘要: There is provided a new antiviral antibiotic designated herein as BU-4344V which is produced by fermentation of a BU-4344V-producing strain of a new microorganism, Actinomadura parvosata subsp. kistnae ATCC No. 55076. Antibiotic BU-4344V is recovered and purified from the fermentation broth by use of extraction, chromatography, and crystallization techniques. BU-4344V has been found to have some antibacterial activity and inhibits the growth of viruses, including influenza virus type A.
