Citrinin derivatives from the marine-derived fungus Penicillium citrinum.
Three new citrinin derivatives, penicitrinols C, D, and E (1-3), along with two known compounds, citrinin (4) and decarboxydihydrocitrinone (5), were isolated from Penicillium citrinum. Their structures were determined by spectroscopic methods and X-ray diffraction analysis. Compounds 1 and 3 demonstrated weak cytotoxicity against the HL-60 cell line.
متن کاملDihydroisocoumarins from the Mangrove-Derived Fungus Penicillium citrinum
Three new dihydroisocoumarin penicimarins G-I (1-3), together with one known dihydroisocoumarin (4) and three known meroterpenoids (5-7), were obtained from a fungus Penicillium citrinum isolated from the mangrove Bruguiera sexangula var. rhynchopetala collected in the South China Sea. Their structures were elucidated by the detailed analysis of spectroscopic data. The absolute configuration of...
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 کاملJBIR-15, a new aspochracin derivative, isolated from a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04.
In the course of our chemical screening program for novel metabolites by LC-MS monitoring, we isolated a new aspochracin derivative, JBIR-15 (1), together with aspochracin, from the culture broth of a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04. The structure of 1 was determined to be N-demethyl aspochracin at the alanyl residue on the basis of extensive NMR and MS analyses.
متن کاملPenilumamide, a novel lumazine peptide isolated from the marine-derived fungus, Penicillium sp. CNL-338.
A novel lumazine peptide, penilumamide (1), was isolated from the fermentation broth of a marine-derived fungal strain, identified as Penicillium sp. (strain CNL-338) and the structure of the new metabolite was determined by analysis of ESI-TOF MS data combined with 1D and 2D NMR experiments.
