Eremophilane-Type Sesquiterpenoids from an Acremonium sp. Fungus Isolated from Deep-Sea Sediments.
Chemical examination of an EtOAc extract of a cultured Acremonium sp. fungus from deep-sea sediments resulted in the isolation of 15 new eremophilane-type sesquiterpenoids, namely, acremeremophilanes A-O (1-15), together with seven known analogues. The structures of new compounds were determined through extensive spectroscopic analyses, in association with chemical conversions and ECD calculati...
متن کاملOosporein from Tremella fuciformis
THE TITLE COMPOUND [SYSTEMATIC NAME: 3,3',6,6'-tetra-hydroxy-4,4'-dimethyl-1,1'-bi(cyclo-hexa-3,6-diene)-2,2',5,5'-tetra-one], C(14)H(10)O(8), was isolated from Tremella fuciformis. The mol-ecule has 2 symmetry, with the mid-point of the C-C bond linking the cyclo-hexa-dienedione rings located on a twofold rotation axis. In the mol-ecule, the ring is approximately planar, with an r.m.s. deviati...
متن کاملUCS1025A, a novel antibiotic produced by Acremonium sp.
antimicrobial activity, and antiproliferative activity against humantumor cell lines. In this paper, we describe the taxonomy of the producing organism, fermentation, isolation, physico-chemical properties and biological activities ofUCS1025A and B. The cultural and taxonomical characteristics of the producing fungal strain KY4917 were as follows. Colonies on 2% malt extract agar medium are 28 ...
متن کاملAn antibacterial hydroxy fusidic acid analogue from Acremonium crotocinigenum.
A fusidane triterpene, 16-deacetoxy-7-beta-hydroxy-fusidic acid (1), was isolated from a fermentation of the mitosporic fungus Acremonium crotocinigenum. Full unambiguous assignment of all (1)H and (13)C data of 1 was carried out by extensive one- and two-dimensional NMR studies employing HMQC and HMBC spectra. Compound 1 was tested against a panel of multidrug-resistant (MDR) and methicillin-r...
متن کاملJBIR-37 and -38, novel glycosyl benzenediols, isolated from the sponge-derived fungus, Acremonium sp. SpF080624G1f01.
In the course of our chemical screening program for new secondary metabolites, we isolated new compounds JBIR-37 (1) and -38 (2) from a culture broth of the marine sponge-derived fungus, Acremonium sp. SpF080624G1f01. The structures of 1 and 2 were determined to be di- and mono-O-beta-D-glucopyranosyloxy-4-(1,1-dimethyl-2-propenyl)benzene on the basis of extensive NMR and MS spectroscopic data,...
