Fungi occupy an important place in the natural world, as
non-photosynthetic organisms, they obtain their nutrients from the
degradation of organic material. They use many of their secondary
metabolites to secure a place in a competitive natural environment
and to protect themselves from predation. The diverse structures,
biosyntheses and biological activities of fungal metabolites have
attracted chemists for many years. Fungi are ubiquitous and their
activities affect many aspects of our daily lives whether it be as
sources of pharmaceuticals and food or as spoilage organisms and
the causes of diseases in plants and man. The chemistry of the
fungi involved in these activities has been the subject of
considerable study particularly over the last fifty years. Although
their ramifications can be large as in the spread of plant
diseases, the quantities of the metabolites which could be isolated
precluded much chemical work until the advent of spectroscopic
methods. Whereas many natural products derived from plants were
isolated prior to the 1960s on a scale which permitted extensive
chemical degradation, this was rarely the case for fungal
metabolites. This book is an introduction to the chemistry of
fungal metabolites. The aim is to illustrate within the context of
fungal metabolites, the historical progression from chemical to
spectroscopic methods of structure elucidation, the development in
biosynthetic studies from establishing sequences and mechanisms to
chemical enzymology and genetics and the increasing understanding
of the biological roles of natural products. The book begins with a
historical introduction followed by a description of the general
chemical features which contribute to the growth of fungi. There
are many thousands of fungal metabolites whose structures are known
and the book does not aim to list them all as there are databases
to fulfill this role. The book's aim is to describe some of the
more important metabolites classified according to their
biosynthetic origin. Biosynthesis provides a unifying feature
underlying the diverse structures of fungal metabolites and the
chapters covering this area begin with a general outline of the
relevant biosynthetic pathway before presenting a detailed
description of particular metabolites. Investigations into these
biosyntheses have utilized many subtle isotopic labelling
experiments and compounds that are fungal pigments and those which
are distinctive metabolites of the more conspicuous Basidiomycetes
are treated separately. Many fungal metabolites are involved in the
interactions of fungi with plants and others are toxic to man and
some of these are described in further chapters. Fungi have the
ability to transform chemicals in ways which can complement
conventional reactions and the use of fungi as reagents forms the
subject of the final chapter. This book will be particularly useful
to anybody about to embark on a career in chemical microbiology by
providing an overall perspective of fungal metabolites as well as
an essential reference tool for more general chemists.
