چکیده
Five novel chromones (1,4-benzopyran-4-ones), among which three are tetracyclic and one contains a sulfonyl group, have been isolated from an Ascomycete, Chaetomium quadrangulatum, as monoamine oxidase inhibitory features, and named chaetoquadrins A (1)-E (5).

Six new constituents from an Ascomycete, Chaetomium quadrangulatum, found in a screening study focused on monoamine oxidase inhibitory activity.
A screening study focusing on monoamine oxidase inhibitory activity on the EtOAc extract of an Ascomycete Chaetomium quadrangulatum, which previously gave five unique chromones possessing this activity (chaetoquadrins A-E (1-5)), this time afforded six new constituents termed chaetoquadrins F-K (6-11) in addition to 1-5. The structures of 6-11 have been deduced on the basis of spectral and chem...
متن کاملA Peroxidase-linked Spectrophotometric Assay for the Detection of Monoamine Oxidase Inhibitors
To develop a new more accurate spectrophotometric method for detecting monoamine oxidase inhibitors from plant extracts, a series of amine substrates were selected and their ability to be oxidized by monoamine oxidase was evaluated by the HPLC method and a new substrate was used to develop a peroxidase-linked spectrophotometric assay. 4-(Trifluoromethyl) benzylamine (11) was proved to be an exc...

Abstract In the present study, eleven compounds (1-11) including nine alkaloids (1-9), one triterpenoid saponin (10) and one formamide (11) were isolated from Talaromyces sp. LGT-2, an endophytic fungus from Tripterygium wilfordi. Their structures were determined based on NMR and ESI-MS spectral data, as well as comparing with previous literature data. This is the first report of the isolation ...

متن کاملInhibition of monoamine oxidase by stilbenes from Rheum palmatum
Seven stilbenes and one catechin were bioactivity-guidedly isolated from the rhizomes of Rheum palmatem. Their structures were identified as piceatannol(1), resveratrol(2), piceid(3), rhapontigenin(4), piceatannol-3'-O-β-D-glucopyranoside(5), rhaponticin(6), catechin(7) and desoxyrhapontigenin(8). Anti-monoamine oxidase (MAO) activities of compounds 1–8 were tested. Compounds 1 and 8 showed sig...
