چکیده

We found a new inhibitor of mammalian DNA topoisomerase I, named topostin, from a bacterial culture. The bacteria was identified as Flexibacter topostinus sp. nov., B-572. Morphological and physiological characteristics, and utilization of sugars were examined. Comparison of the strain with known species of the genus Flexibacter was made and indicates that the strain is a new species of the genus Flexibacter. The bacteria produced the inhibitor in parallel with their growth up to 72 hours.

A new topoisomerase-II inhibitor, BE-10988, produced by a streptomycete. I. Taxonomy, fermentation, isolation and characterization.

A new topoisomerase inhibitor, BE-10988, was isolated from the culture broth of a strain of actinomycetes. The producing strain had a close resemblance to Streptomyces fimicarius and Streptomyces xanthocidicus. The active principle was extracted from the whole broth of strain BA10988 with ethyl acetate and purified by silica gel chromatography and by HPLC. BE-10988 increased DNA-topoisomerase c...

Topostatin, a novel inhibitor of topoisomerases I and II produced by Thermomonospora alba strain No. 1520. I. Taxonomy, fermentation, isolation and biological activities.

A novel inhibitor of topoisomerases designated as topostatin was isolated from the culture filtrate of Thermomonospora alba strain No. 1520. Topostatin inhibited the relaxation of supercoiled pBR322 DNA by calf thymus topoisomerase I, and also inhibited the relaxation of supercoiled pBR322 DNA and decatenation of kinetoplast DNA by human placenta topoisomerase II. Topostatin had neither ability...

Spenolimycin, a new spectinomycin-type antibiotic. I. Discovery, taxonomy and fermentation.

Spenolimycin, a new spectinomycin-type antibiotic, was discovered in the fermentation broth of a new actinomycete named Streptomyces gilvospiralis sp. nov. strain AB634D-177. Although a small amount of spectinomycin is coproduced by strain AB634D-177, the culture is different from other known spectinomycin-producing actinomycetes. Spenolimycin was obtained by conventional submerged culture in 1...

Two novel antifungal antibiotics, PF1163A and B, were isolated from the fermentation broth of Penicillium sp. They were purified from the solid cultures of rice media using ethyl acetate extraction, silica gel and Sephadex LH-20 column chromatographies. PF1163A and B showed potent growth inhibitory activity against pathogenic fungal strain Candida albicans but did not show cytotoxic activity ag...
