Isolation of Three New Azaphilones, Luteusins C, D, and E, from an Ascomycete, Talaromyces luteus.

Abstract

Three new azaphilones, named luteusins C, D, and E, were isolated from an Ascomycete, Talaromyces luteus, together with luteusins A and B (previous tentative designations: TL-1 and -2, respectively), which had formerly been isolated as monoamine oxidase (MAO)-inhibitory azaphilones from the fungus. The new compounds had no MAO-inhibitory activity.
