    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.

    摘要: Novel peptides of the formula ##STR1## wherein R is CH.sub.3 --(CH.sub.2).sub.6, CH.sub.3 --(CH.sub.2).sub.4 --CH.dbd.CH--(CH.sub.2).sub.2 and CH.sub.3 (CH.sub.2).sub.8 having antibiotic and antitumor activity are prepared by cultivation of the novel microorganism Polyangium brachysporum. Enzymatic hydrolysis of those peptides gives other peptides useful as intermediates in the preparation of peptides having activity as antibiotics and/or antitumor agents.
