Bioactive macrolides and polyketides from marine dinoflagellates*
Absolute stereochemistry of amphidinolides G and H, potent cytotoxic 27and 26-membered macrolides, respectively, isolated from a marine dinoflagellate Amphidinium sp., was determined by X-ray diffraction analysis, synthesis of a degradation product, and chemical interconversion. Six new macrolides, amphidinolides H2~H5, G2, G3, and W, have been isolated from a marine dinoflagellate Amphidinium ...
متن کاملDeep cutaneous infection with Microsphaeropsis arundinis: report of two Japanese cases.
© 2015 The Authors. doi: 10.2340/00015555-2091 Journal Compilation © 2015 Acta Dermato-Venereologica. ISSN 0001-5555 Coelomycetes are asexual fungi which produce their conidiospores within fruiting structures known as conidiomata. They are ubiquitous in soil and freshwater environments, and recognized as plant pathogens (1, 2). Although human infections with coelomycetous fungi are exceedingly ...
متن کاملActinomycetes from the South China Sea sponges: isolation, diversity, and potential for aromatic polyketides discovery
Marine sponges often harbor dense and diverse microbial communities including actinobacteria. To date no comprehensive investigation has been performed on the culturable diversity of the actinomycetes associated with South China Sea sponges. Structurally novel aromatic polyketides were recently discovered from marine sponge-derived Streptomyces and Saccharopolyspora strains, suggesting that spo...
متن کاملDioxatricyclic and oxabicyclic polyketides from Trichocladium opacum.
Five new polyketides, trichocladinols D-H (1-5) with dioxatricyclic (1-3) and oxabicyclic (4 and 5) skeletons, and the known massarilactone C (6) were isolated from the solid-substrate fermentation cultures of the ascomycete fungus Trichocladium opacum. The structures of 1-5 were determined mainly by NMR experiments, and 1, 3, and 4 were confirmed by X-ray crystallography. The absolute configur...
متن کاملMetabolites from Microsphaeropsis olivacea, an endophytic fungus of Pilgerodendron uviferum.
Seven compounds belonging to different structural skeletons were isolated from Microsphaeropsis olivacea grown in liquid and solid media. The enalin derivative 7-hydroxy-2,4-dimethyl-3(2H)-benzofuranone is reported for the first time, while additional spectroscopic information is provided for the acetates of botrallin and ulocladol. The activity of the isolated compounds was assessed towards th...
