PREFACE
This volume, the fourth in the series "The Prostagiandin System",
contains most of the presentations at the International School of
Pharmacology on "Drugs Effecting Leukotrienes and other
Eicosanoid pathways" held in Erice, Sicily, at the "Ettore
Majorana Center" on 9-20 September 1984.
The discovery of a new class of biologically active compounds is
always exciting even if at the present time knowledge is
advancing very rapidly; this is particu1arly true for the
eicosanoids. Evidence for a pivotal role of arachidonic acid as a
precursor of mediators and modulators of various cell functions
is now weil established. This broad knowledge has stimulated the
search for drugs capable of interfering with the eicosanoid
system and since the discovery of the mechanism of action of
Aspirin, new drugs have become available in order to act more
specifica11y not only at the level of different enzymes involved
in arachidonic acid conversion but also more selectively at the
receptor si tes where the acti ve metaboli tes are effecti ve. In
addition to this, several stable synthetic derivatives of
endogenous unstable prostanoids mimicking their functions in a
variety of physiopatho19gical processes are also of potential
therapeutic interest.
This volume will certainly help scientists and students wi th
different interests related to those diseases that stern from
arachidonic acid metabolites interactions in hypersensitivity
phenomena and in host defence mechanisms.
We like to take this opportunity to expresse our gratitude to all
the speakers for their important contributions and to NATO
ADVANCED STUDY INSTITUTE for making this Course possible.

ProstagIandin research has developed rapidly especially during
the past two decades. The elucidation of the chemistry, biosynthe
sis and metabolism of the prostagIandin system as weIl as advances
concerning the biological effects and physiological roles of
prostaglandins and related compounds are important areas in this
development (1). The new knowledge hasformed the basis for under
standing the role of prostaglandins in many pathophysiological
processes and for the therapeutic use of prostaglandins in various
diseases.
After the elucidation of the chemistry of the prostaglandins
and their biosynthesis from polyunsaturated fatty acids, studies
on the mechanism of prostagIandin biosynthesis demonstrated the
existence of unstable endoperoxide intermediates as PGG2 and PGH~.
The finding that the endoperoxides had unique biological effects
indicated that additional biologically active derivatives were
formed from the endoperoxides (2). These considerations formed the
basis for the discovery of thromboxane A2 and subsequently also
prostacyclin (3,4).
The leukotrienes constitute another group of biologically ac
tive derivatives formed from polyunsaturated fatty acids. They
were originally discovered in leukocytes (LTB4), however, studies
on their mechanism of biosynthesis resulted In the recognition of
an unstable intermediate (LTA4). This finding formed the basis for
the elucidation of the chemistry of slow reacting substance of
anaphylaxis (LTC~, LTD4, LTE4) (5). The leukotrienes have potent
biological effects related to inflammation and allergy.
