Abstract
Preface
Subtle and specific recognition between complex macromoleculesis at the core of virtually
every life process. Knowledge about the chemical nature of these interactions is
rapidly increasing at present. From the beginning, synthetic organic chemistry has
been an important tool in the acquisition of this knowledge, the elucidation of the
genetic code being the most dramatic example of the contributions chemists have
madeto biology.
A decade ago, the advent of genetic engineering opened up newhorizonsto the nucleic
acids or protein chemist. With the techniques of molecular cloning at hand one
could for thefirst time in history select individual molecules from synthetic mixtures
andin principle prepare unlimited amounts of chemically homogeneous macromolecules.
Today, we have just begun to see someofthe far-reaching consequencesof
this revolutionary development.
Yet, molecular cloning hasits limitations: in planning a synthesis, one is in practice
constrained to the naturally occurring monomersof nucleic acids and proteins. Often
however, one would like to introduce a non-natural monomerunit into a nucleic acid or
protein molecule to study, for instance, the effect of an individual functional group ona
biological process. In such studies, the biochemisthasto rely again on his classicalorganic-
synthetic repertoire exclusively.
Beyond theintroduction of functional groups that exceed the repertoire of natural nucleosides
and amino acids, post-translational protein modifications such as the addition
of oligosaccharide side chains, are an additional area of great interest that is not
easily accessible by genetic engineering.
In this book wehavetried to bring together a number of examplesillustrating the importance
of organic synthesis for contemporary molecular biology in different areas of
interest. These include
— Synthesis of nucleic acids that cannot be amplified by molecular cloning and their
application in studying processes of mutagenesis/carcinogenesis and DNA-protein
interaction
— DNAsynthesis and genetic diagnosis
— Protein design
— Chemical peptide synthesis in the developmentof vaccines
— Cell-surface oligosaccharides and cell-cell interactions
The book evolved from a symposium weorganized and held in Braunschweig in September
1984 with the aim of bringing together a set of leading specialists in diverse
fields and initiating an interdisciplinary exchange of views and ideas. Thus the bookreflects
the individual blend of this symposium — no attempt at a comprehensive review
has been made.
Wethank the sponsorsof the meeting, Stiftung Volkswagenwerk, Fonds der Chemischen
Industrie and Bundesministerium für Forschung und Technologie. Our special
thanks go to the symposium speakers and chairmen, and the contributors to this
book.
