The Chemistry and Biology of Nitroxyl (HNO) provides first-of-its-kind coverage of the intriguing biologically active molecule called nitroxyl, or azanone per IUPAC nomenclature, which has been traditionally elusive due to its intrinsically high reactivity. This useful resource provides the scientific basis to understand the chemistry, biology, and technical aspects needed to deal with HNO. Building on two decades of nitric oxide and nitroxyl research, the editors and authors have created an indispensable guide for investigators across a wide variety of areas of chemistry (inorganic, organic, organometallic, biochemistry, physical, and analytical); biology (molecular, cellular, physiological, and enzymology); pharmacy; and medicine. This book begins by exploring the unique molecule’s structure and reactivity, including important reactions with small molecules, thiols, porphyrins, and key proteins, before discussing chemical and biological sources of nitroxyl. Advanced chapters discuss methods for both trapping and detecting nitroxyl by spectroscopy, electrochemistry, and fluorescent inorganic cellular probing. Expanding on the compound’s foundational chemistry, this book then explores its molecular physiology to offer insight into its biological implications, pharmacological effects, and practical issues. Presents the first book on HNO (nitroxyl or azanone), an increasingly important molecule in biochemistry and pharmaceutical research Provides a valuable coverage of HNO’s chemical structure and significant reactions, including practical guidance on working with this highly reactive molecule Contains high quality content from recognized experts in both industry and academia

Since 1988, there has been much literature published on the chemistry of nitric oxide, particularly in the field of S-nitrosation and the chemistry of S-nitroso compounds. Written by a chemist for the chemistry community, this book provides an update of the chemistry of nitrosation reactions, dealing with both the synthetic and mechanistic aspects of these reactions. It also looks at the chemistry of nitric oxide in relation to the amazing biological properties of this simple diatomic molecule, which were unknown until around 1990. * Provides an update on previously published literature on nitric oxide chemistry * Contains chapters on reagents for nitrosation, nitrosation at nitrogen, aliphatic and aromatic carbon, oxygen, sulfur and metal centres * Looks at hot research topics such as synthesis, properties and reactions of s-nitrosothiols

This is not a book on NO biology, nor about hemoglobin, nor about heme-based sensors per se. Of course, it covers all these topics and more, but above all, it aims at providing a truly multidisciplinary perspective of heme-diatomic interactions. The overarching goal is to build bridges among disciplines, to bring about a meeting of minds. The contributors to this book hail from diverse university departments and disciplines – chemistry, biochemistry, molecular biology, microbiology, zoology, physics, medicine and surgery, bringing with them very different views of heme-diatomic interactions. The hope is that the juxtaposition of this diversity will lead to increased exchanges of ideas, approaches, and techniques across traditional disciplinary boundaries. The authors represent a veritable Who’s Who of heme protein research and include John Olson, Tom Spiro, Walter Zumft, F. Ann Walker, Teizo Kitagawa, W. Robert Scheidt, Pat Farmer, Marie-Alda Gilles-Gonzalez, and many other equally distinguished scientists. Extremely distinguished list of authors Multidisciplinary character – equally suitable for chemists and biochemists Covers the hottest topics in heme protein research: sensors, NO biology, new roles of hemoglobin, etc.

Nitroxyl (HNO) is a biologically relevant small molecule with considerable clinical promise for the treatment of heart failure. However, studies of the chemistry and biology of nitroxyl are hampered by its instability in aqueous solution. To aid in biological and chemical studies, nitroxyl donors (molecules that degrade to release HNO) have been synthesized which utilize a 3-hydroxy-2-naphthyl methyl (HNM) OH protecting group. Our group0́9s focus is on the synthesis of nitroxyl donors that rapidly release HNO under physiological conditions through photoactivation. First generation HNO donors released HNO upon photoactivation, but competition was also observed from a redox side reaction. In this study, we are probing the impact of a methyl substituent at the benzylic position on these competing processes. The synthesis and photochemical anaylsis of such a donor are herein described.

This essential volume comprehensively discusses redox-active therapeutics, focusing particularly on their molecular design, mechanistic, pharmacological and medicinal aspects. The first section of the book describes the basic aspects of the chemistry and biology of redox-active drugs and includes a brief overview of the redox-based pathways involved in cancer and the medical aspects of redox-active drugs, assuming little in the way of prior knowledge. Subsequent sections and chapters describe more specialized aspects of central nervous system injuries, neurodegenerative diseases, pain, radiation injury and radioprotection (such as of brain, lungs, head and neck and erectile function) and neglected diseases (e.g., leishmaniasis). It encompasses several major classes of redox-active experimental therapeutics, which include porphyrins, salens, nitrones, and most notably metal-containing (e.g., Mn, Fe, Cu, Zn, Sb) drugs as either single compounds or formulations with nanomaterials and quantum dots. Numerous illustrations, tables and figures enhance and complement the text; extensive references to relevant literature are also included. Redox-Active Therapeutics is an invaluable addition to Springer’s Oxidative Stress in Applied Basic Research and Clinical Practice series. It is essential reading for researchers, clinicians and graduate students interested in understanding and exploring the Redoxome—the organism redox network—as an emerging frontier in drug design, redox biology and medicine.

The oxidation of primary and secondary alcohols to the corresponding carbonyl compounds is of fundamental importance in organic synthesis, due to the wide use of these products as precursors and intermediates for many drugs, vitamins and fragrances. However, traditional oxidants are often toxic and release considerable amounts of by-products. As an alternative, oxygen is among the cheaper and less polluting stoichiometric oxidants, and the implementation of a transition metal-based catalyst in combination with oxygen represents an emerging alternative to the traditional procedures. This book aims to give an overview of the aerobic oxidation of alcohols catalyzed by transition metals, and covers the most important advances in the last fifteen years. Following an introductory chapter on homogeneous-, heterogeneous- and nano-catalysis, use of copper, ruthenium, palladium, gold, vanadium and iron are discussed in turn. The book concludes with a useful overview that includes representative experimental procedures. This book will provide a valuable reference to organic chemists and green chemists in academia and industry.
