Pigments of fungi (Macromycetes).
This review summarises progress reported in the chemical, biological and mycological literature dealing with the isolation, characterisation and chemistry of pigments manufactured by those fungi that… Expand
Slime moulds (Myxomycetes) as a source of new biologically active metabolites
- W. Steglich
An investigation of the chemistry of acellular slime moulds revealed the presence of several types of metabolites. Tetramic acid derivatives and physarochrome A are responsible for the pigmentation… Expand

From roots of Homalomena aromatica three new sesquiterpene alcohols, 1 beta, 4 beta, 7 alpha-trihydroxyeudesmane, homalomenol A, and homalomenol B were isolated together with oplopanone, oplodiol and… Expand
Mitorubrin derivatives from Hypoxylon fragiforme
Three dihydroanthracenones from Gasteria bicolor.
The stem and leaves of Gasteria bicolor afforded three new dihydroanthracenones namely 3,4-dihydro-4,6,9-trihydroxy-7-carbomethoxy-8-methyl-1(2H)-anthraceno ne (gasteriacenone C), which were determined by spectroscopic methods including 2D NMR techniques. Expand
Synthesis of arcyriarubin b and related bisindolylmaleimides
Abstract The reaction of indolyl magnesium bromide with 2,3-dibromo-N-methylmaleimide (3) in toluene leads to bisindolylmaleimides 6. In THF a monosubstitution product 5 is obtained which after… Expand
Knipholone: a unique anthraquinone derivative from Kniphofia foliosa
Abstract The roots of Kniphofia foliosa afforded, in addition to chrysophanol, a novel anthraquinone named knipholone, whose structure was determined by spectroscopic methods as well as by… Expand

Oxocrinine and other alkaloids from Crinum americanum
From bulbs of Crinum americanum oxocrinine, an intermediate in the biosynthesis of Amaryllidaceae alkaloids, was isolated for the first time and identified by spectroscopic evidence, chemical transformations and partial syntheses. Expand
