Naturally Occurring Quinones aims to discuss where quinones, a major group of organic compounds that are considered as pigments, can be found in nature. The book also explains its significance in chemistry and other related fields. The text also mentions the different plant and animal origins of these compounds. The book covers the biogenesis and distribution of these organic compounds; their identification and spectra; and the different kinds of quinolones, which include benzoquinones, naphthaquinones, julichromes, and laccaic acids. The text also elaborates on anthracyclinones and their stereochemistry; extended quinolones, including elsinochromes, erythroaphins, xanthoaphins, chrysoaphins, and aphinins; and miscellaneous quinolones, such as royleanones, tanshinones, isotanshinones, and mitomycins. The text is recommended for students and practitioners in the field of chemistry, biochemistry, and biology, especially those who want to further understand quinolones, their importance in nature and different species, and their possible uses.

The Biochemistry of Plants: A Comprehensive Treatise, Volume 7: Secondary Plant Products focuses on the biochemistry of secondary compounds, including tissue culture and differentiation, complexes, and plant systematics. The selection first elaborates on the physiological roles of secondary natural products, tissue culture and the study of secondary natural products, and turnover and degradation of secondary natural products. Discussions focus on degradative reactions of nitrogenous and phenolic compounds, concept of turnover of secondary products, and plant-vertebrate interactions. The text then elaborates on secondary plant products and cell and tissue differentiation; compartmentation in natural product biosynthesis by multienzyme complexes; and secondary metabolites and plant systematics. The manuscript examines the stereochemical aspects of natural products biosynthesis, nonprotein amino acids, and amines. Topics include tryptamines, phenethylamines, and histamine, nonprotein amino acids as analogues and antimetabolites, chemistry and biogenesis, and nonprotein amino acids as indexes for chemotaxonomy. The book also tackles glycosylation and glycosidases; transmethylation and demethylation reactions in the metabolism of secondary plant products; and oxygenases and the metabolism of plant products. The selection is a vital reference for researchers interested in the biochemistry of secondary compounds.

Organic chemistry's innovative breadth is especially noteworthy in the area of natural products synthesis. Since the early 1970s, this landmark chemical reference has been documenting the newest and most important of these, in a readily understood format, that clearly traces each of their synthetic routes. Volume Eight, the latest in the series, contains a long-awaited look at the synthesis of tri- and tetracyclic diterpenes, along with the synthesis of naturally occurring quinones. Recent interest in the biologically important polysaccharides has led to a detailed consideration of that compound class. Finally, this new volume contains a look at the strategies and methods specific to natural products containing the spiroketal functional group. The Total Synthesis of Natural Products, Volume Eight, continues the meticulous work of the series, providing chemists with an entirely up-to-date and convenient guide to the critical new syntheses essential to organic chemistry's continuing evolution.

The book gives a hitherto unavailable overview on a huge class of – so far largely neglected – natural products, characterized by one common structural element, a biaryl axis. Covering more than 1300 references, this review mainly focuses on the isolation of these compounds from natural sources, their structural elucidation with special regard to the biaryl axis as a possible stereoelement, their biological activities, and on their biosynthetic origin. Informative summaries on stereochemical aspects connected to a stereogenic axis and on the determination of axial configurations are given, as well as some selected examples out of atroposelective total syntheses. Never has this subject been addressed in such a detailed way, especially not concerning the great variety of different structural subgroups. This book should find the way to the library of any scientist working in the field of natural product, since it provides data on an overwhelming number of naturally occurring substances.

Enzyme Prodrug Strategies For Cancer Therapy

Antibody-directed enzyme prodrug therapy (ADEPT) directly addresses the major problem in cancer chemotherapy-its lack of selectivity. Antibody delivery combined with the amplification provided by the enzymatic activation of prodrugs enables selection to be made between tumour and normal tissue. ADEPT offers a novel field of opportunities in the therapy of systemic cancer and may be a major advance for the treatment of solid tumours. This book is the first to describe ADEPT in detail. Each chapter reviews an aspect of the immunology, enzymology, biochemistry, chemistry, and cancer chemotherapy which have been integrated into the ADEPT concept. An additional chapter describes the related approach of gene-directed enzyme prodrug therapy (GDEPT). This latter approach is still in its infancy but ADEPT has entered the clinic. The initial clinical studies with ADEPT are included and discussed in detail.
