The first contribution presents coumarins, the largest group of 1-benzopyran derivatives found in plants. Coumarin chemistry remains one of the major interest areas of phytochemists, especially because of their structural diversity and medicinal properties, along with the wide-ranging bioactivities of these compounds, inclusive of analgesic, anticoagulant anti-HIV, anti-inflammatory, antimicrobial, antineoplastic, antioxidant, and immunomodulatory effects. The second contribution presents a comprehensive survey of the many aspects of PAD biochemistry and physiology. The third contribution gives a comprehensive overview of secondary metabolites from higher fungi, with more than 700 references highlighting the isolation, structure elucidation, biological activities, chemical synthesis, and biosynthesis of pigments, nitrogen-containing compounds, and terpenoids from mushrooms.
This thesis outlines the first synthesis of a new complex branched polymer architecture that aims to combine the benefits of dendrimers with the simplicity of conventional polymerisation. There is no other available literature on these remarkable materials, dubbed hyperbranched polydendrons, due to their novelty. The new materials were shown to have very high molecular weights (>1,000,000 g/mol), exceptional self-assembly and encapsulation behaviour and unparalleled functionalisation capabilities, and were studied pharmacologically to determine their potential as oral nanomedicine candidates. The detailed investigation of the chemical variables involved in synthesising hyperbranched polydendrons has shown that their self-assembly and pharmacological behaviour can be turned on and off and fine-tuned by altering the composition of the materials. The permeation of the self-assembled particles through model gut epithelium suggests the potential for oral dosing of drug loaded nanomedicines that result in circulating nanoparticles - a research goal that is currently being pursued by several groups around the globe.
This fourth volume in the series on biochemistry looks at foundations in modern biochemistry. Topics covered include: the genetic solution; the genetic basis of development; DNA repair; evolution in an RNA world; nitrogen fixation; solute channels; viruses; biochemistry in retrospect and propspect.
This updated monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further chapters discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other "methanogenic" mammals contribute significantly to the global methane budget; especially the rumen hosts an impressive diversity of methanogens. This makes this updated volume an interesting read for scientists and students in Microbiology and Physiology.

Driving further the research on mammalian alkaline phosphatase structure and function, Phosphatase Modulators collects expert contributions into one "how to" manual for basic scientists interested in initiating a drug discovery effort. While this book contains the traditional method chapters and some typical reviews on the structure and known functions of phosphatases, other contributions are meant to discuss approaches and alternatives useful in making "go/no-go" decisions in high throughput screening (HTS) and lead optimization campaigns. Many chapters focus on tissue-nonspecific alkaline phosphatase (TNAP) as well as protein phosphatases. Written for the highly successful Methods in Molecular Biology series, chapters in this volume include the kind of detail and key implementation advice that promotes reproducible results. Step-by-step and practical, Phosphatase Modulators offers a path to understanding many of the facets and complexities associated with undertaking a drug discovery effort and will serve as a roadmap to initiating those efforts.
Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.
Experts from around the world review the current field of the immunobiology of heat shock proteins, and provide a comprehensive account of how these molecules are spearheading efforts in the understanding of various pathways of the immune system. This one-stop resource contains numerous images to both help illustrate the research on heat shock proteins, and better clarify the field for the non-expert. Heat shock proteins (HSPs) were discovered in 1962 and were quickly recognized for their role in protecting cells from stress. Twenty years later, the immunogenicity of a select few HSPs was described, and for the past 30 years, these findings have been applied to numerous branches of immunology, including tumor immunology and immunosurveillance, immunotherapy, etiology of autoimmunity, immunotherapy of infectious diseases, and expression of innate receptors. While HSPs can be used to manipulate immune responses by exogenous administration, they appear to be involved in initiation of de novo immune responses to cancer and likely in the maintenance of immune homeostasis.
Poly (ADP-ribose) Polymerases (PARPs) are abundant and ubiquitous proteins that regulate crucial processes of the cell cycle, DNA repair, genomic stability, and transcriptional regulation. Being involved in basic cell functions, PARPs mediate rapid responses to such environmental factors as stress, infection, nutrition and hormonal signals. Whereas PARP inhibitors can suppress tumor growth and proliferation in certain breast, ovarian, and prostate cancers, understanding how PARP controls cellular functions is essential for the development of novel cancer treatments strategies. Divided into three convenient sections, Poly(ADP-Ribose) Polymerase: Methods and Protocols aims to explain how PARP proteins act within the normal development of an organism as well as in pathogenic conditions, seeks to advance the knowledge of developmental pathways regulation, and endeavors to facilitate the development of new therapeutic drugs and methods to target PARP-dependent processes. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Poly(ADP-Ribose) Polymerase: Methods and Protocols serves as an ideal guide to scientists who wish to continue exploring this exciting and progressive research field.
This book aims to bridge the gap in understanding how protein-tyrosine phosphatases (PTPs), which carry out the reverse reaction of tyrosine phosphorylation, feature in cancer cell biology. The expertly authored chapters will first review the general features of the PTP superfamily, including their overall structure and enzymological properties; use selected examples of individual PTP superfamily members, to illustrate emerging data on the role of PTPs in cancer; and will review the current status of PTP-based drug development efforts. Protein Tyrosine Phosphatases in Cancer,from renowned researchers Benjamin Neel and Nicholas Tonks, is invaluable reading for researchers in oncology, stem cell signaling,and biochemistry.

High quality leads provide the foundation for the discovery of successful clinical development candidates, and therefore the identi?cation of leads is an essential part of drug discovery. The process for the identi?cation of leads generally starts with the screening of a compound collection, either an HTS of a relatively large compound collection (hundreds of thousands to one million plus compounds) or a more focused screen of a smaller set of compounds that have been preselected for the target of interest. Virtual screening methods such as structure-based or pharmacophore-based searches can complement or replace one of the above approaches. Once hits are identi?ed from one or more of these screening methods, they need to be thoroughly characterized in order to con?rm activity and identify areas in need of optimization. Finally, once fully characterized hits are identi?ed, preliminary optimization through synthetic modi?cation is carried out to generate leads. Parallel optimization of all properties, including biological, physicochemical, and ADME is the most ef?cient approach to the identi?cation of leads. Hit characterization is described in the previous chapter. The focus of this chapter is on hit optimization and the identi?- tion of leads. After a general overview of these processes, examples taken from the literature since 2001 will be used to illustrate speci?c points. There are also a number of excellent reviews covering the lead identi?cation process [1-6].
Receptor Tyrosine Kinase: Structure, Functions and Role in Human Disease, for the first time, systematically covers the shared structural and functional features of the RTK family. Receptor Tyrosine Kinases (RTKs) play critical roles in embryogenesis, normal physiology and several diseases. And over the last decade they have become the Number 1 targets of cancer drugs. To be able to conduct fundamental research or to attempt to develop pharmacological agents able to enhance or intercept them, it is essential first to understand the evolutionary origin of the 58 RTKs and their roles in invertebrates and in humans, as well as downstream signaling pathways. The assembly of chapters is written by experts and underscores commonalities between and among the RTKs. It is an ideal companion volume to The Receptor Tyrosine Kinase: Families and Subfamilies, which proceeds, family by family through all of the specific subfamilies of RTKs, along with their unique landmarks.

Thermodynamics was created in the ?rst half of the 19th century as a theory designed to explain the functioning of heat engines converting heat into mechanical work. In the course of time, while the scope of research in this ?eld was being extended to a wider and wider class of energy transformations, thermodynamics came to be considered as a general theory of machines identi?ed with energy transducers. Imp- tant progress in biochemistry in the ?rst half of the 20th century, and in molecular biology in the second half, made it possible to think of treating even living organisms as machines, at least on the subcellular level. However, success in applying thermodynamics to elucidate the phenomenon of life has been rather mitigated. Two reasons seem to be responsible for this unsatisfactory s- uation. Nineteenth century thermodynamics dealt only with simple (homogeneous) systems in complete equilibrium. Although during the 20th century a nonequilibrium thermodynamics was developed, sta- ing with the Onsager theory of linear response and ending with the Prigogine nonlinear theory of dissipative structures, these theories still concern the originally homogeneous systems. Because living organisms are complex systems with a historically frozen spatial and functional structure, a thermodynamics of both nonequilibrium and complex s- tems is needed for their description. The ?rst goal of the present book is to formulate the foundations of such a thermodynamics.
This book presents modern and classic analytical approaches that are crucial for the biochemical and functional characterization of the archetypal protein, glyceraldehyde-3-phosphate dehydrogenase (GAPDH). The distinguishing feature of the book is that it covers, in addition to other methods, some of the uncommon but valuable techniques as well. For example, in-gel visualization of enzyme activity, immunoblotting protocols for native (non-denatured) proteins, and proteins resolved by pH-gradient [IEF-isoelectrofocusing], etc. These expedient methods are relevant and vital for the verification of biochemical properties of GAPDH, or similar protein of interest. This work outlines detailed protocols that are essential to investigate classical (cellular) and recently reported extracellular (secretory) isoforms of GAPDH. Precisely, the book covers techniques pertinent to enzymatic and non-enzymatic analysis of GAPDH that include, but not limited to, electrophoretic mobility shift assay (EMSA), two-dimensional (2D)-immunoblotting, immunofluorescence/confocal microscopy, mass spectrometry, ion-exchange and affinity chromatography. Readers will discover the importance of the experimental methods described in the book as they relate to the evaluation of the role and significance of GAPDH. Furthermore, majority of the methods described in the book have also been validated in the author's laboratory, besides other research groups worldwide, underlining the repeatability and reproducibility of the protocols. Each method begins with an abstract and a brief background emphasizing its application and relevance. This will enable the readers to determine the choice of experimental design according to their research objectives. The book explains the methods systematically with ample illustrations to facilitate quick and easy comprehension of the practical knowledge. Although the book is focused on GAPDH, many of the protocols may be adopted to other proteins or enzymes with minimal modifications. Noteworthy, it is unequivocally established that GAPDH is a multifunctional protein involved in several cellular processes of health & disease conditions. Hence, this book will be a valuable practical guide for young researchers, scientists and clinician-scientists.

Respiration in plants, as in all living organisms, is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a planta (TM)s carbon budget. Depending on species and environmental conditions, it consumes 25-75% of all the carbohydrates produced in photosynthesis a" even more at extremely slow growth rates. Respiration in plants can also proceed in a manner that produces neither metabolic energy nor carbon skeletons, but heat. This type of respiration involves the cyanide-resistant, alternative oxidase; it is unique to plants, and resides in the mitochondria. The activity of this alternative pathway can be measured based on a difference in fractionation of oxygen isotopes between the cytochrome and the alternative oxidase. Heat production is important in some flowers to attract pollinators; however, the alternative oxidase also plays a major role in leaves and roots of most plants. A common thread throughout this volume is to link respiration, including alternative oxidase activity, to plant functioning in different environments. |
