Pigments of fungi. Part 43.1,2 Cardinalins 1–6, novel pyranonaphthoquinones from the fungus Dermocybe cardinalis Horak

Abstract

The cardinalins 1–6, a series of stereochemically complex, cytotoxic pyranonaphthoquinone dimers and their hydroquinone precursors, have been isolated from the New Zealand toadstool Dermocybe cardinalis and their structures established by spectroscopic methods. The cardinalins are the first pyranonaphthoquinones to be found in the Higher Fungi.
