title: Six new constituents from an Ascomycete, Chaetomium quadrangulatum, found in a screening study focused on monoamine oxidase inhibitory activity.
abstract: 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 chemical data, and 7 and 8 have shown appreciable monoamine oxidase inhibitory activity.
