Cystothiazoles A and B, new bithiazole-type antibiotics from the myxobacterium Cystobacter fuscus.
New bithiazole-type antibiotics, cystothiazoles A (C20H26N2O4S2) and B (C20H26N2O5S2), have been isolated from a culture broth of the myxobacterium, Cystobacter fuscus. The gross structures of these compounds were elucidated by spectroscopic analysis, and their absolute stereochemistry was determined by chemical degradation of cystothiazole A. Cystothiazole A inhibits fungi and human tumor cell...

Epoxyquinomicins A and B, new antibiotics from Amycolatopsis.
Sir: In the course of a screening program for new antibiotics, we isolated newantibiotics, epoxyquinomicins A (1) and B (2) from the culture broth of Amycolatopsis sp. MK299-95F4, which was isolated from a soil sample collected at Sendai city, Miyagi Prefecture, Japan. In this paper we report the production, isolation, physico-chemical properties, biological properties and structures of 1 and 2...
متن کاملNoboritomycins A and B, new polyether antibiotics.
Noboritomycins A and B, two new polycyclic ionophoric polyethers were isolated from a strain of Streptomyces noboritoensis. The crystal structure and absolute configuration of noboritomycin A were established by X-ray analysis of its silver salt C43/63O14Ag. Noboritomycin A is the first metabolic polyether possessing two carboxylic acid functions on the carbon backbone (C-31), namely a free aci...
متن کاملGalacardins A and B, new glycopeptide antibiotics.
A strain of actinomycetes identified as Saccharothrix sp. SANK 64289 was found to produce new antibiotics, galacardins A and B. Their physico-chemical properties showed that they were new members of glycopeptide antibiotics. They were structurally related to beta-avoparcin but differed from it only in sugar composition. Though beta-avoparcin does not contain galactose, galacardins A and B did c...
