A new anthracycline antibiotic N-formyl-13-dihydrocarminomycin.
Sir: During the course of our screening for inducers of mouse myeloid leukemic cell (M1)1) differentiation, we have recently isolated four active components related to the carminomycins from the cultured broth of an actinomycete. The isolation and structures of these components are reported in this paper. The producing organism of the active substances was isolated from a soil sample collected ...
متن کاملA new anthracycline antibiotic micromonomycin from Micromonospora sp.
In the course of our continuing search for novel antimicrobial agents,1-5) we have isolated a novel antibacterial anthracycline, micromonomycin (1), from culture Micromonospora sp. Micromonomycin was identified as a new anthracycline using high resolution ESIMS and extensive NMR spectroscopic analyses. In this paper, we describe the isolation and structure elucidation of 1. The biological activ...
متن کاملIsolation of New Anthracycline
Sir: During the course of our screening program for new anthracycline antibiotics, four /5-rhodomycinone glycosides, A447 A, B, C and D were found in the acetone extract of cultured mycelia of a strain designated as A447. Based on NMR spectral analysis and chemical degradation, A447 A and B were identified as cosmomycins D and C1^, respectively, while A447 C and D were found to be new congeners...
متن کاملArugomycin, a new anthracycline antibiotic. I. Taxonomy, fermentation, isolation and physico-chemical properties.
Arugomycin (AGM) is a new anthracycline antibiotic produced by strain No. 1098-AV2 which was identified as Streptomyces violaceochromogenes. AGM was isolated by solvent extraction, silicic acid chromatography and Sephadex LH-20 column chromatography. Acid treatment of AGM gave the chromophore, named arugorol, which was identified as 4'-epi-nogalarol, and sugar moieties. AGM inhibited the growth...
متن کاملMetabolic products of microorganisms. 225. Elloramycin, a new anthracycline-like antibiotic from Streptomyces olivaceus. Isolation, characterization, structure and biological properties.
Elloramycin (1), a new antibiotic produced by Streptomyces olivaceus strain Tü 2353, was detected by chemical screening. The dark yellow compound, molecular formula C32H36O15, is weakly active against a variety of Gram-positive bacteria, especially streptomycetes and against stem cells of L-1210 leukemia. Acidic hydrolysis of the antibiotic liberated elloramycinone (3) as aglycone and 2,3,4-tri...
