摘要:
New antibiotic compounds, Fortimicin factors KG.sub.1, KG.sub.2 and KG.sub.3 are produced by fermentation of microorganisms belonging to the genus Micromonospora. The antibiotic compounds are accumulated in the culture liquor and are isolated therefrom.
摘要:
The Antiboitic AR-5 complex is elaborated by a novel species of the Micromonospora; namely, Micromonospora polytrota. The microorganism also elaborates a number of minor components including the gentamicin complex and a complex of anthroquinone antibiotics.
摘要:
A new fortimicin, fortimicin AL. The compound is coproduced in the fermentation of Micromonospora olivoasterospora ATCC No. 21819, 31009 or 31010 along with fortimicin A, Isofortimicin, Fortimicin E and a number of other minor factors. The compound is useful as an intermediate in synthesizing fortimicin AL derivatives which are useful as antibiotics.
摘要:
A new aminoglycoside antibiotic, Isofortimicin, which can be produced by fermentation of Micromonospora olivoasterospora ATCC 21819, 31009 and 31010 and isolated from the fermentation broth.
摘要:
A compound represented by the following Structural Formula (A) or a salt thereof. The compound or the salt thereof is suitably produced from a microorganism belonging to the genus Saccharothrix and can be suitably used as a prostaglandin production inhibitor.
摘要:
Four new antibiotics which are denominated istamycin A, istamycin B, istamycin A.sub.o and istamycin B.sub.o, and which are useful as antibacterial agents, are produced by fermentation of a new microorganism, Streptomyces tenjimariensis.
摘要:
An antibiotic substance KA-7038 selected from the group consisting of the compounds having formulae I to VII described in claim 1, mixtures thereof and acid addition salts thereof; an antibiotic composition composed of (i) antibiotically effective amount of aforesaid antibiotic substance KA-7038, and (ii) a pharmaceutically acceptable diluent or carrier. The antibiotic substance KA-7038 can be produced by cultivating an antibiotic substance KA-7038-producing strain belonging to genus Streptomyces, for example Streptomyces sp. KC-7038, and isolating the antibiotic substance KA-7038 from the culture broth.
