Chaetochalasin A: A New Bioactive Metabolite from Chaetomium Brasiliense
Chaelochalasin A (1). a new bioactive fungal metabolite with a previously undescribed ring system. has been isolated from an EIOAc extract of Chaetomium brasiliense (NRRL 22999). The structure of I was determined by NMR experiments and single-crystal X-ray diffraction analysis. © 1998 ElseVier SCience Ltd. All nghts reserved.
متن کاملLipohexin, a new inhibitor of prolyl endopeptidase from Moeszia lindtneri (HKI-0054) and Paecilomyces sp. (HKI-0055; HKI-0096). I. Screening, isolation and structure elucidation.
Lipohexin was isolated as a novel lipohexapeptide (I) (C39H68N6O9) from three fungal strains, Moeszia lindtneri HKI-0054, Paecilomyces sp. HKI-0055 and Paecilomyces sp. HKI-0096. The structure was elucidated by detailed mass spectrometric and NMR experiments. The proline-containing peptide displays moderate antibacterial activity against Bacillus subtilis ATCC 6633 and inhibits competitively th...
متن کاملCuevaenes A and B, new polyene carboxylic acids from Streptomyces sp. HKI 0180.
In the course of a screening for newmetabolites from strains of actinomycetes we disclosed Streptomyces sp. HKI 0180 as the producer of cuevaenes A (1) and B (2). The strain was isolated from a soil sample from the cave of Altamira (Spain). In this paper we report the production, isolation, structure elucidation and biological properties of 1 and 2 (Fig. 1). An agar slant culture of the above s...
متن کاملBioactive Secondary Metabolites from a New Terrestrial Streptomyces sp. TN262
During our search for Streptomyces spp. as new producers of bioactive secondary metabolites, the ethyl acetate extract of the new terrestrial Streptomyces isolate TN262 delivered eight antimicrobially active compounds. They were identified as 1-acetyl-beta-carboline (1), tryptophol (2), cineromycin B (3), 2,3-dihydrocineromycin B (4), cyclo-(tyrosylprolyl) (5), 3-(hydroxyacetyl)-indole (6), bre...
متن کاملLuteophanol D, New Polyhydroxyl Metabolite from Marine Dinoflagellate Amphidinium sp
Luteophanol D (1), a new polyhydroxyl linear carbon-chain metabolite, has been isolated from the cultured marine dinoflagellate Amphidinium sp., which was isolated from Okinawan marine acoel flatworm Pseudaphanostoma luteocoloris. The structure of 1 was elucidated by detailed analyses of 2D NMR spectra. Luteophanol D (1) possesses two tetrahydropyran rings and twenty-three hydroxyl groups on C6...
