    摘要: A novel class of antitumour compounds has been recognised based on the isolation from a new marine microbe, strain PO13-046, belonging to the genus Actinomadura sp.), of a compound designated IB-00208. The class of the formulae (I) or (II) where R1 can be hydrogen, acyl, alkyl, alkenyl, aryl, benzyl, alkali metal, and/or sugar, and R2 and R3 can be hydrogen, alkyl, or together R2 and R3 form an unsaturated bond. Such compounds demonstrate an interesting activity several cancel cell lines and against Gram-positive bacteria.

    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.
