Global warming and, even more recently, the COVID pandemic have brought into public focus our dependence on science and the lens with which it considers the world. Science is providing opportunities for new ways of thinking and has always opened new avenues for creative thought and advances. This book examines and summarises the developments and changes in approaches to organic and natural product chemistry as seen through the published works of the author and seeks to place them in a philosophical and societal context. Demonstrating and explaining how scientists and, more particularly, chemists arrive at a world view, it will show how this is predicated not just by scientific advances but also by societal influences. The author uses personal experience to detail progress through science. Techniques used in such investigations are alluded to but not described in detail since the interested reader can access the full published papers if required. Interesting both to the general, scientifically literate reader and to the specialist wanting information on natural product chemistry, the book does not create a rulebook for carrying out natural product chemistry but rather examines the processes that lie beneath the development of natural product chemistry and how this enables chemists to examine and interpret the world. Students of chemistry (whatever their age or stage of career) may also be interested in reading how peer reviewed and published material relates to the wider society view.

The chemical synthesis of isotopically labelled compounds is a pre-requisite for many chemical, biochemical and medicinal investigations. The constraints imposed by the requirements for regiospecific labelling and, in some instances, the time-scale of the synthesis often lead to quite different synthetic strategies to those that are used for the unlabelled material. Whilst there are many specialist papers, reviews and long books devoted to particular isotopes, there is no currently available short introductory book devoted to the organic chemistry of isotopic labelling. The aim of this book is to introduce research workers to a variety of methods that have been used to achieve these synthetic labelling objectives before exploring a particular method in detail. It covers a number of different isotopes and the methods that have been used to introduce them into organic compounds. Labelling methods also provide useful undergraduate teaching examples of modern synthetic reactions and their stereochemical consequences using relatively simple substrates. The book will therefore have a wider appeal than just those involved in using isotopes in research such as environmental and pharmaceutical chemists as well as organic chemists.

In the late 1990s, there was an explosion of research on ionic liquids and they are now a major topic of academic and industrial interest with numerous existing and potential applications. Since then, the number of scientific papers focusing on ionic liquids has risen exponentially, including a few edited multi-author books covering the latest advances in ionic liquids chemistry and several volumes of symposium proceedings. Much of the content in these books and volumes is written using technical jargon that only scientists at the cutting edge of ionic liquids research will understand and ionic liquids are hardly covered in most modern chemistry textbooks. This is the first single-author book on ionic liquids and the first introductory book on the topic. It is written in a clear, concise and consistent way. The book provides a useful introduction to ionic liquids for those readers who are not familiar with the topic. It is also wide ranging, embracing every aspect of the chemistry and applications of ionic liquids.

With an emphasis on interdisciplinary content, this book will appeal to the worldwide organic chemistry and engineering research communities.

There is an increasing awareness that materials and chemicals produced from fossil fuels are not sustainable, both in terms of the pollution caused by the extraction and production processes, and the fact that there is only a finite supply of these fossil fuels. Therefore, there is a strong incentive to find sources for chemicals and materials from source materials that we know we can continue to generate. Plants are a source of a wide variety of chemicals, many with interesting properties, and these chemical feedstocks are considered renewable rather than finite. Green Chemistry and Green Materials from Plant Oils and Natural Acids covers the application of these natural materials in producing polymers, lubricants and plasticisers.

Antibiotic resistance is a global health concern. Strains of pathogenic microorganisms that have developed resistance to multiple antibiotics, such as MRSA, are extremely difficult to treat, and alternative methods for tackling pathogenic microorganisms are in demand. One potential target for new therapeutics is inhibition of quorum sensing: how microorganisms communicate and form biofilms in a density-dependent manner. Inhibiting this system via ‘quorum quenching'(QQ) is a promising route to new pharmaceuticals and for controlling biofilm formation and growth. Quorum sensing also provides interesting possibilities in synthetic biology for producing novel products, biosensors, bioactive molecules, and so on. This book covers the biology of quorum sensing and quenching, and potential sources of QQ enzymes and other inhibitors, as well as an overview of their mechanism and potential biotech applications. The book also covers the potential for new drug development from QQ, covering a range of related topics including protein engineering, imaging and computational studies, and integrated systems. This book is an ideal companion to researchers in chemical biology and medicinal chemistry, particularly those interested in biofilm formation, quorum sensing, novel antimicrobial development, synthetic biology and enzymology.

Transportation currently takes up around a third of overall energy usage, of which the majority is petroleum-based gasoline. Petroleum is both a finite resource and a big contributor to the carbon emissions that are causing climate change. To continue to benefit from transportation whilst mitigating climate change it is essential to find alternatives to petroleum-based gasoline. Although a lot of recent developments have focused on electrifying transport the infrastructure for large scale uptake of electric vehicles is still lacking and it may be less practical in some parts of the world than others. Biofuels, therefore, still have a role to play in improving the sustainability of our transportation systems. The term green gasoline refers to biofuels intended to be direct drop-in replacements for petroleum-based gasoline. Such products allow vehicles to run on biofuel without any engine modifications and, being made from biomass, they are both renewable and have a better carbon emission profile than petroleum-based gasoline. Green Gasoline covers a range of new technologies being used to produce these biofuels and compares them to petroleum-based fuels in terms of sustainability. It will be an interesting read for those working in fuel chemistry as well as green chemists and anyone with an interest in transport sustainability.

The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.

Circadian rhythms have been shown to be ubiquitous and critically important in the experimental laboratory, accounting for the difference between life and death in response to identical stimulus. The partly endogenous nature of circadian rhythms has been well documented and methods for their characterisation have been developed enabling the cellular and molecular mechanisms to be understood. Chronobiology and Chronomedicine aims to provide a review of these mechanisms underlying circadian rhythms and illustrate the role of the brain's suprachiasmatic nuclei in the ‘pace-making'process and the effects caused by ‘clock genes'present in almost all cells. Beyond the mechanisms involved, the book discusses the relationship between body systems, disease, and proper circadian function; in particular, how disruption of the circadian rhythm is associated with ill health and disease status from observations made at the organismic level. The book is organised to be an ideal introduction for the postgraduate in various fields, reviewing developments and outlining methods to show the depth and breadth of chronobiology and chronomedicine, as well as an invaluable companion to researchers and healthcare professionals working in the field with an interest in developing novel therapeutic approaches.

Hydrogels are highly hydrated three dimensional networks with the ability to mimic the extracellular matrix of bodily tissues and have thus found application in a wide range of biomedical applications. Unique physiochemical properties such as biocompatibility, water permeability, stimuli responsiveness and self-healing characteristics make them especially useful for use as scaffolds and matrices drug delivery, tissue engineering/regeneration and sensing. Their weak and brittle nature, however, often limits their widespread application where improved mechanical strength is required. To resolve this problem, there has been a significant amount of research into the improvement of their mechanical properties. Among these efforts, versatile multicomponent hydrogels have received much attention as their physiochemical properties can be structurally engineered to provide a wide range of desired properties. These multicomponent formulations also allow for the combination of natural and synthetic polymers, which offers the scope to exploit the advantages of each component, with the synergistic effects resulting from mutual interactions. This book critically discusses the fundamental chemistry, synthesis, characterisation, physiochemical and biological properties of various types of multicomponent hydrogels. It reviews the different strategies employed in designing and synthesizing cutting-edge multicomponent hydrogels and their key applications in biomedical fields. The work is suitable for researchers working in the specific area of multicomponent hydrogels, and also more generally for those working in materials science, biomedical engineering, biomaterials science and tissue engineering.

The phytochemical constituents of plants fall into two main categories based on their role in basic metabolic processes: primary and secondary. Primary metabolites are involved in basic life functions and are similar in all living cells, whereas secondary metabolites are derived from subsidiary pathways. Although traditionally referred to as secondary metabolites, more recently these compounds have been termed ‘plant specialized metabolites', as the exact biochemical boundary between primary and secondary metabolites has not been fully established. Plant specialized metabolites are the main elements in the study and use of ‘medicinal'plants and herbs, as well as in nutrition and food chemistry. In modern medicine, plant specialized metabolites provide many of the lead compounds in the production of medicines targeted at treating a broad variety of diseases. Such metabolites also play an important role in sessile plants to resist and withstand different biotic and abiotic stresses. Plant specialized metabolites are classified according to their chemical structures and this book will present the different classes in turn, while discussing their sources and distribution in plant families, their biosynthetic pathways, and their important and notable uses in phytochemistry and pharmacology. Chemical Diversity of Plant Specialized Metabolites will be a useful guide and reference point for chemists and students in many disciplines including synthetic organic chemists, medicinal chemists, plant scientists, pharmacognosists, chemical ecologists, bioengineers, and synthetic biologists, in addition to those working in related fields.

It will also update current researchers on recent developments, explored properties, and arising challenges of covalent materials.

Completely revised and updated, this 2nd Edition of Reactivity and Mechanism in Organic Chemistry is an ideal introduction to the quantitative description of organic reactivity for students in undergraduate and masters chemistry programmes. The book proceeds logically from qualitative molecular orbital theory as a tool for the description of bonding phenomena to combining this with thermochemical data to rationalise concepts such as molecular strain and hyperconjugation. Next, transition state theory, for examining organic reactivity phenomena, is introduced and its relation to energy surfaces and simple rate equations is discussed. On this basis more specific reactivity concepts commonly used in organic chemistry are explored such as the Bell–Evans–Polanyi principle, Marcus theory, HSAB principle, Hammett correlations, the Mayr–Patz equation, and FMO theory. How these reactivity models are applied is demonstrated for pericyclic reactions and selected rearrangement reactions involving transient intermediates such as radicals, diradicals, or carbocations, and for reactions involving classical electrophile/nucleophile combinations.

The covalent conjugation of potent cytotoxic agents to monoclonal antibodies, known as antibody-drug conjugates (ADCs) is a powerful approach in the field of targeted treatment of cancer. Clearly, both monoclonal antibody and cytotoxic payload are crucial elements in determining the clinical value of an ADC and have receive ample attention. However, the structural element connecting the two –the chemical linker– also plays an essential role in mode-of-action, efficacy, pharmacokinetics and safety profile of an ADC, but is often underappreciated in considerations of ADC design.Chemical Linkers in Antibody–Drug Conjugates aims to shine a detailed light on the various key attributes of chemical linkers in ADCs, for drug-to-antibody ratio, for stability, for release mechanism of payload, for pharmacokinetics, for stability determination, and for efficacy and safety. Ideal for postgraduate students and active researchers in drug discovery and development, this book provides a comprehensive description of linkers used in ADCs (clinical and late preclinical), insight into key quality attributes of linkers for ADCs, and aids the reader in understanding the role of linker chemistry and designing new ADCs.

Sustainable Organic Synthesis is a comprehensive collection of contributions, provided by specialists in Green Chemistry, covering topics ranging from catalytic approaches to benign and alternative reaction media, and innovative and more efficient technologies.

Drug repurposing is the development of existing drugs for new uses: given that 9 in 10 drugs that enter drug development are never marketed and therefore represent wasted effort, it is an attractive as well as inherently more efficient process. Three repurposed drugs can be brought to market for the same cost as one new chemical entity; and they can also be identified more quickly, an important benefit for patients whose diseases are progressing faster than therapeutic innovation. But repurposing also requires a fresh look at configuring pharmaceutical R&D, considering clinical, regulatory and patent issues much earlier than would otherwise be the case; a holistic gedanken experiment almost needs to be undertaken at the very start of any repurposing development. In addition to new ways of thinking, the discovery of repurposing opportunities can take advantage of artificial intelligence techniques to match the perfect new use for an existing drug. And while repurposing of medicines has been in the mind of every doctor since Hypocrates, modern clinical practice will simply have to adapt to new repurposing techniques in an age where the number of known diseases is increasing much faster than the healthcare dollars available.

Perfluoroalkyl substances (PFAS) are a diverse group of human-made chemicals that are used in a wide range of consumer and industrial products. They are under intense scrutiny due to environmental concerns and there is a call to ban new PFASs entering the market. That said, this book is not intended to wave the banner against PFASs per se; rather it provides a balanced overview of the field, from basic synthesis through to applications, why some current PFASs are and may remain the right substance for the job, as well as addressing the challenges and alternatives.Covering organofluorine chemistry to fluoropolymers and their applications in various sectors from biomedical to agrochemical, energy and electrical industries, this book is a solid introduction to the topic and demonstrates why fluorinated products are still useful in many domains. With risk assessment and alternatives to PFASs included, it provides a considered account of both the positive applications of PFASs and the pressing environmental concerns.Suitable for academics and industrial practitioners working in the fields of organic and macromolecular chemistries, it will also appeal to end-users who want to learn about the technology, applications and elimination or recycling of such fluorinated products.

Completely revised and updated this new edition once again unifies all the theories of the origin of biomolecular homochirality together in a single source. This complete, interdisciplinary review of an intriguing subject condenses a large and disparate range of contributions from journals in almost every scientific field. The various theories have been organized, interrelated and explained in a unified way. It is fundamental, comprehensive and structured to be accessible for educational purposes.

There have been many great advances in the field of biomedical imaging in recent years, with supramolecular chemistry playing a key role in the evolution of modern imaging techniques. Non-covalent supramolecular interactions are fundamental to countless biological processes, from host–guest binding to the stabilisation of complex structures. Supramolecular chemistry techniques can be employed to create probes that can be targeted to either exploit or disrupt these interactions, giving the potential for both diagnostic and therapeutic effects. Furthermore, in techniques such as contrast enhanced MRI, controlling the interactions between solvent molecules and the imaging agent is crucial to the development of the technique.With rapid growth in the synthesis and study of molecular imaging agents, the understanding of their associated techniques has sometimes lagged behind. Supramolecular Chemistry in Biomedical Imaging will fill this gap by clarifying the state of current understanding and the nature of the underlying problems inherent to addressing problems in biology. It will cover both the techniques used in imaging and the molecular and supramolecular systems used to exploit them. This publication targets academics coming to the field from mainstream supramolecular chemistry, research graduates and undergraduates interested in supramolecular chemistry, synthesis or imaging agents and imaging techniques for biomedical applications.

Originally published in Portuguese, this book is divided into three sections: the chemistry of aldehydes, ketones, nitriles, imines and derivatives; the chemistry of carboxylic and carbonic acids and derivatives; and the chemistry of alpha, beta-unsaturated carbonyls. The authors have merged aspects of valence bond and molecular orbital theories in order to discuss structural and physico-chemical properties and reactivity and stereochemical outcomes of the most relevant reactions for these functional groups. The book provides representative experimental procedures for key reactions; highlights to contextualize the concepts; properties (industrial applications, biochemical significance and catalytic developments in order to cope with the major tenets of the green chemistry approach) and includes some biographical notes for the scientists who contributed to this field. It will help advanced level undergraduate and graduate students to understand and become well acquainted with the reactions of carbonyl compounds and derivatives. The integrated approach is considered an attractive feature of this book since students receive relatively little exposure to molecular orbital theory at the undergraduate level. The juxtaposition of conventional valence bond theory with molecular orbital theory fills a largely unmet pedagogical niche.

Authored by leading experts in the enzymology of natural product biosynthesis, this completely revised and updated edition provides a description of the types of natural products, the biosynthetic pathways that enable the production of these molecules, and an update on the discovery of novel products in the post-genomic era. Although some 500 000 – 600 000 natural products have been isolated and characterized over the past two centuries, there may be a 10-fold greater inventory awaiting immediate exploration based on biosynthetic gene cluster predictions. The approach of this book is to codify the chemical logic that underlies each natural product structural class as they are assembled from building blocks of primary metabolism. This second edition integrates many new findings into the sets of principles of the first edition that parsed categories of natural product chemistries into the underlying enzymatic mechanisms and the catalytic machinery for building the varied and complex end product metabolites. New chapters include evaluation of a core set of thermodynamically activated but kinetically stable metabolites that power both primary and secondary metabolic pathways. Also, after decades of uncertainty about the existence of various pericyclase classes, a series of genome mining, heterologous expression, and enzymatic activity characterization have validated a plethora of pericyclases over the past decade. The several types of pericyclases are involved in biosynthetic complexity generation of almost every major category of natural products. This text will serve as a reference point for chemists of every subdiscipline, including synthetic organic chemists and medicinal chemists. It will also be valuable to bioinformatic and computational biologists, pharmacognocists and chemical ecologists, and bioengineers and synthetic biologists.

Green chemistry has progressed from being a driver for change in the chemical and allied industries to being a critical part of chemical education at all levels. The future chemist must be able to practice their trade in the light of increasing concerns about waste and resources, the safety of chemicals in consumer products, and increasingly restrictive legislation. While there are green chemistry educational resources available including lectures and experiments as well as numerous books on green chemistry and major green chemical technologies, there is no “green equivalent” of a standard organic chemistry textbookSystematically covering a variety of well-known reactions that commonly feature in standard organic textbooks this book supplements and supports the standard organic chemistry texts. It highlights the main sustainability issues of classical and contemporary organic transformations and critically evaluates them within a metric of established Green Chemistry Principles noting where additional efforts are needed to improve their environmental footprint.

Metal–organic frameworks (MOFs) are crystalline porous materials constructed from metal ions/clusters and organic linkers, combining the merits of both organic and inorganic components. Due to high porosity, rich functionalities, well-defined open channels and diverse structures, MOFs show great potentials in field such as gas storage and separation, catalysis, and sensing. Combining them with polymers tunes their chemical, mechanical, electrical and optical properties, and endows MOFs with processability. Covalent organic frameworks (COFs) are crystalline porous materials built from organic molecular units with diverse structures and applications. Hybrid materials with intriguing properties can be achieved by appropriate preparation methods and careful selection of MOFs/COFs and polymers, broadening their potential applications. This book documents the latest research progress in MOF/COF-polymer hybrid materials and reviews and summarises hybridization strategies to achieve MOF/COF polymeric composites. It also introduces various applications and potential applicable scenarios of hybrid MOF/COF polymers. Hybrid Metal–Organic Framework and Covalent Organic Framework Polymers offers an overview to readers who are new to this field, and will appeal to graduate students and researchers working on porous materials, polymers, hybrid materials, and supramolecular chemistry.

CHEMISTRY STUDENT GUIDES. GUIDED BY STUDENTSWhy did the drug thalidomide cause birth defects? What is the chemical difference between sucrose and lactose in your food? Stereochemistry holds the answer and is essential to the understanding of the chemistry of life. Stereochemistry is an important concept that often causes confusion amongst students when they learn it for the first time. Unlike most other areas of chemistry, it requires the chemist to visualise molecules in 3D, which can be difficult. In this book we deal with tricky concepts like conformation and configuration, how to represent them accurately and how to use the correct terms to describe them in both organic and inorganic chemistry. We involved students in the writing process to ensure we deal with areas that you find difficult, in an understandable language. With problems designed to focus on common errors and misconceptions, real life examples, and practical hands-on exercises coupled with visualisation tips, our intention is to give you the tools to become confident in stererochemistry. Complementing mainstream organic textbooks, or self-study, this book is for anyone who has struggled with describing alkenes as E or Z, assigning R and S absolute configurations, drawing Newman projections or chair representations of cyclohexanes, axial chirality, understanding the stereochemistry of octahedral metal complexes and indeed explaining complexities observed in NMR spectra. Chemistry Student Guides are written with current students involved at every stage, guiding the books towards the most challenging aspects of the topic. Student co-authors for Introduction to Stereochemistry are Caroline Akamune, Michael Lloyd and Matthew Taylor.

Functional, flexible and lightweight products are in high demand for modern technologies ranging from microelectronics to energy storage devices. The majority of polymers are thermal and electrical insulators, which hinder their use in these applications. The conductivity of polymers can be significantly enhanced by the incorporation of conducting inorganic nanoparticles. However, this relies not only on the structure and function of the inorganic particles, but is highly determined by the morphology and dispersion of the nanoparticles, interfacial interactions and fabrication technologies of the composites. This book highlights the synthesis, chemistry and applications of two-dimensional (2D) inorganic nanoplatelets in polymer nanocomposites. Chapters cover technical challenges, such as surface functionalisation, compatibilization, interfacial interaction, dispersion, and manufacturing technologies of the polymer nanocomposites. The book also discusses the applications of these polymer nanocomposites in electronics and energy storage. With contributions from global experts, the book provides a much-needed overview of the field, giving advanced undergraduates, postgraduates and other researchers with a convenient introduction to the topic.

Photochemistry is an important facet in the study of the origin of life and prebiotic chemistry. Solar photons are the unique source of the large amounts of energy likely required to initiate the organisation of matter to produce biological life. The Miller–Urey experiment simulated the conditions thought to be present on the early earth and supported the hypothesis that under such conditions complex organic compounds could be synthesised from simpler inorganic precursors. The experiment inspired many others, including the production of various alcohols, aldehydes and organic acids through UV-photolysis of water vapour with carbon monoxide. This book covers the photochemical aspects of the study of prebiotic and origin of life chemistry an ideal companion for postgraduates and researchers in prebiotic chemistry, photochemistry, photobiology, chemical biology and astrochemistry.

Designed for teaching, this English translation of the tried and tested Organometallic Chemistry 2/e textbook from the Japan Society of Coordination Chemistry can be used as an introductory text for chemistry undergraduates and also provide a bridge to more advanced courses. The book is split into two parts, the first acts as a concise introduction to the field, explaining fundamental organometallic chemistry. The latter covers cutting edge theories and applications, suitable for further study. Beginning with fundamental reaction patterns concerning bonds between transition metals and carbon atoms, the authors show how these may be combined to achieve a desired reaction and/or construct a catalytic cycle. To understand the basics and make effective use of the knowledge, numerous practice questions and model answers to encourage the reader's deeper understanding are included. The advanced section covers the chemistry relating to bonds between transition metals and main group elements, such as Si, N, P, O and S, is described. This chemistry has some similarities to transition metal-carbon chemistry, but also many differences and unique aspects, which the book explains clearly. Organometallic complexes are now well known and widely used. In addition, transition metal complexes with main group element other than carbon as a ligating atom are becoming more important. It is thus important to have a bird's-eye view of transition metal complexes, regardless of the ligand type. This book acts as solid introduction for chemistry students and newcomers in various fields who need to deal with transition metal complexes.

Nanoparticles can be synthesised via a number of methods, including chemical vapor deposition, ball milling, laser ablation, thermal decomposition and chemical reduction. Chemical reduction is usually preferred, due to its ease and cost-effectiveness. There are several types of compound used as reducing agents in nanoparticle synthesis, and one recent development is the use of biological entities as environmentally friendly reductants. This book will highlight the role of reducing agents in the chemical synthesis of nanoparticle systems, presenting the main categories of reducing agents, which vary on reactivity, selectivity, availability and toxicity. It will provide a comprehensive presentation of both modern and more conventional types of reagents. Emphasis will be given on the presentation not only of the functionality, but also of all the different advantages and limitations of each kind of reducing agent. With contributions from global experts, this title will be appropriate for graduate students and researchers in nanochemistry, colloidal synthesis, inorganic chemistry, organometallic chemistry, chemical engineering, physical chemistry, materials science, biology and physics.
