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 کاملAcremostrictin, a highly oxygenated metabolite from the marine fungus Acremonium strictum.
The novel natural product acremostrictin was isolated from the culture broth of Acremonium strictum, a marine fungus collected from a Choristida sponge off the coast of Korea. Structurally, acremostrictin is a tricyclic lactone of an unprecedented skeletal class based on combined spectroscopic and X-ray crystallographic analyses. The new compound exhibited weak antibacterial and moderate antiox...
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,...
متن کاملRegulation of the Cyanide-Resistant Alternative Respiratory Pathway in the Fungus Acremonium chrysogenum
This review summarises the current knowledge on the biochemical and physiological events that directly or indirectly alter the engagement of the cyanide-resistant alternative respiratory pathway in the cephalosporin C producer filamentous fungus Acremonium chrysogenum. Particular emphasis is placed on the role this activity plays in the overproduction of antibiotic, and also on the critical fer...
متن کاملResponse of Cellulase Activity in pH-Controlled Cultures of the Filamentous Fungus Acremonium cellulolyticus
Cellulase production was investigated in pH-controlled cultures of Acremonium cellulolyticus. The response to culture pH was investigated for three cellulolytic enzymes, carbomethyl cellulase (CMCase), avicelase, and beta-glucosidase. Avicelase and beta-glucosidase showed similar profiles, with maximum activity in cultures at pH 5.5-6. The CMCase activity was highest in a pH 4 culture. At an ac...
