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.

摘要: A novel aminoglycoside antibiotic complex designated herein as Bu-2183 is produced by fermentation of Pseudomonas sp. strain D946-B83, A.T.C.C. 31086. Complex Bu-2183 is known to consist of at least five components, said components being herein designated Bu-2183 A, A.sub.2, B, C and D. The complex and the individual aminoglycoside components Bu-2183 A, A.sub.2, and B are found to have a broad spectrum of antibacterial activity and are especially useful in inhibiting aminoglycoside-resistant organisms including Pseudomonas species.
