Phytochemicals as Lead Compounds for New Drug Discovery


Book Description

Phytochemicals as Lead Compounds for New Drug Discovery presents complete coverage of the recent advances in the discovery of phytochemicals from medicinal plants as models to the development of new drugs and chemical entities. Functional bioactive compounds of plant origin have been an invaluable source for many human therapeutic drugs and have played a major role in the treatment of diseases around the world. These compounds possess enormous structural and chemical diversity and have led to many important discoveries. This book presents fundament concepts and factors affecting the choice for plant-based products, as well as recent advances in computer-aided drug discovery and FDA drug candidacy acceptance criteria. It also details the various bioactive lead compounds and molecular targets for a range of life-threatening diseases including cancer, diabetes, and neurodegenerative diseases. Written by a global team of experts, Phytochemicals as Lead Compounds for New Drug Discovery is an ideal resource for drug developers, phytochemists, plant biochemists, food and medicinal chemists, nutritionists and toxicologists, chemical ecologists, taxonomists, analytical chemists, and other researchers in those fields. It will also be very valuable to professors, students, and researchers in this domain. - Presents fundamental concepts and factors affecting choice for plant-based products - Details the FDA drug candidacy acceptance criteria, including bottlenecks and way forward - Highlights recent advances in computational-based drug discovery - Focuses on the discovery of new drugs and potential druggable targets for the treatment of chronic diseases of world importance




Lead


Book Description

Lead covers the salient aspects of the chemistry of lead, its environmental impact, and its effects on health. The technical, economic and social importance of Lead, at the present time, is beyond all doubt. However, over the last few decades little attention has been given to its behaviour (the properties and applications of its compounds, the environmental distribution of these derivatives, and their impacts on living creatures), this book addresses that gap. It includes coverage of historical aspects, lead mining and production, metal properties, common lead compounds, uses of lead and its derivatives, coordination chemistry, organometallic chemistry, environmental chemistry, toxicity mechanisms, and treatment strategies for lead poisoning. Finally, describing analytical procedures for the determination of lead in chemical, biological and environmental samples. - Written by a team of university teachers and researchers with extensive experience in the fields of the chemistry, analytical determination and environmental and health impact of lead and other heavy metals - For readers interested in the chemistry and biochemistry of lead and its effects on ecosystems - Provides comprehensive knowledge about lead toxicity and preventive measures against lead poisoning

Lead: Its Effects on Environment and Health


Book Description

Volume 17, entitled Lead: Its Effects on Environment and Health of the series Metal Ions in Life Sciences centers on the interrelations between biosystems and lead. The book provides an up-to-date review of the bioinorganic chemistry of this metal and its ions; it covers the biogeochemistry of lead, its use (not only as gasoline additive) and anthropogenic release into the environment, its cycling and speciation in the atmosphere, in waters, soils, and sediments, and also in mammalian organs. The analytical tools to determine and to quantify this toxic element in blood, saliva, urine, hair, etc. are described. The properties of lead(II) complexes formed with amino acids, peptides, proteins (including metallothioneins), nucleobases, nucleotides, nucleic acids, and other ligands of biological relevance are summarized for the solid state and for aqueous solutions as well. All this is important for obtaining a coherent picture on the properties of lead, its effects on plants and toxic actions on mammalian organs. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 17, which are written by 36 internationally recognized experts from 13 nations. The impact of this recently again vibrant research area is manifested in nearly 2000 references, over 50 tables and more than 100 illustrations (half in color). Lead: Its Effects on Environment and Health is an essential resource for scientists working in the wide range from material sciences, inorganic biochemistry all the way through to medicine including the clinic ... not forgetting that it also provides excellent information for teaching.




Nature's Building Blocks


Book Description

A readable, informative, fascinating entry on each one of the 100-odd chemical elements, arranged alphabetically from actinium to zirconium. Each entry comprises an explanation of where the element's name comes from, followed by Body element (the role it plays in living things), Element ofhistory (how and when it was discovered), Economic element (what it is used for), Environmental element (where it occurs, how much), Chemical element (facts, figures and narrative), and Element of surprise (an amazing, little-known fact about it). A wonderful 'dipping into' source for the familyreference shelf and for students.




Bioactive Compounds from Natural Sources, Second Edition


Book Description

The first edition of Bioactive Compounds from Natural Sources was published in a period of renewed attention to biologically active compounds of natural origin. This trend has continued and intensified—natural products are again under the spotlight, in particular for their possible pharmacological applications. Largely focusing on natural products as lead compounds in drug discovery, Bioactive Compounds from Natural Sources, Second Edition: Natural Products as Lead Compounds in Drug Discovery is actually a completely new volume containing surveys of selected recent advances in an interdisciplinary area covering chemistry of natural products, medicinal chemistry, biochemistry, and other related topics. Written by some of the most reputed scientists in the field, this second edition includes new chapters from authors who contributed to the first edition as well as many chapters compiled by new authors. Introducing the reader to strategies and methods in the search for bioactive natural products, this book covers topics including: Natural sources of bioactive compounds such as aquatic cyanobacteria, filamentous fungi, and tropical plants, The tremendous potentiality of metabolic engineering of natural products biosynthesis The contribution of emerging or developing technologies to the study of bioactive natural compounds, namely computational methods and circular dichroism The potential of natural or natural-derived compounds for specific therapeutic applications: treatment of viral diseases, regulation of hypoxia-inducible factor, antimalarials, modulation of angiogenesis, and antitumor and wound-healing activity Selected examples of natural product families and related synthetic analogues, namely polyphenols and campthotecins Compiled for researchers and Ph.D. students working in interdisciplinary fields, this book will also be appreciated by readers without a background in chemistry interested in bioactive natural products, their biological and pharmacological properties, and their possible use as chemopreventive or chemotherapeutic agents. Conversely, the biological and pharmacological data and methods are accessible by chemists.
