Conformation In Biology And Drug Design

The Peptides: Analysis, Synthesis, Biology, Volume 7: Conformation in Biology and Drug Design focuses on the analysis of peptides, emphasizing the use of physical methods in peptide conformational analysis and the relationship of conformational properties of peptides to biological properties. This book consists of nine chapters. Chapter 1 provides a brief overview of the perspective on the application of physical methods to peptide conformational analysis. The use of circular dichroism (CD) spectroscopy to examine the conformational properties of peptides in solution is elaborated in Chapter 2, while the use of fluorescence spectroscopy to examine the special relationships of aromatic side-chain groups to one another is discussed in Chapter 3. In Chapter 4, the use of various theoretical methods to calculate the conformations of peptides is described. The methods used to stimulate peptide conformations and dynamics are outlined in Chapter 5. The last four chapters examine various aspects of the use of nuclear magnetic resonance (NMR) in peptide conformational analysis. This volume is suitable for biologists, specialists, and researchers interested in peptides and proteins.

The present work offers a snapshot of the state-of-the-art of crystallographic, analytical, and computational methods used in modern drug design and development. Topics discussed include: drug design against complex systems (membrane proteins, cell surface receptors, epigenetic targets, and ribosomes); modulation of protein-protein interactions; the impact of small molecule structures in drug discovery and the application of concepts such as molecular geometry, conformation, and flexibility to drug design; methodologies for understanding and characterizing protein states and protein-ligand interactions during the drug design process; and monoclonal antibody therapies. These methods are illustrated through their application to problems of medical and biological significance, such as viral and bacterial infections, diabetes, autoimmune disease, and CNS diseases. As approaches to drug discovery have changed over time, so have the methodologies used to solve the varied, new, and difficult problems encountered in drug discovery. In recent years we have seen great progress in the fields of genetics, biology, chemistry, and medicine, but there are still many unmet medical needs, from bacterial infections to cancer to chronic maladies, that require novel, different, or better therapies. This work will be of interest to researchers and policy makers interested in the latest developments in drug design.

Introducing the most recent advances in crystallography, nuclear magnetic resonance, molecular modeling techniques, and computational combinatorial chemistry, this unique, interdisciplinary reference explains the application of three-dimensional structural information in the design of pharmaceutical drugs.

With the most comprehensive and up-to-date overview of structure-based drug discovery covering both experimental and computational approaches, Structural Biology in Drug Discovery: Methods, Techniques, and Practices describes principles, methods, applications, and emerging paradigms of structural biology as a tool for more efficient drug development. Coverage includes successful examples, academic and industry insights, novel concepts, and advances in a rapidly evolving field. The combined chapters, by authors writing from the frontlines of structural biology and drug discovery, give readers a valuable reference and resource that: Presents the benefits, limitations, and potentiality of major techniques in the field such as X-ray crystallography, NMR, neutron crystallography, cryo-EM, mass spectrometry and other biophysical techniques, and computational structural biology Includes detailed chapters on druggability, allostery, complementary use of thermodynamic and kinetic information, and powerful approaches such as structural chemogenomics and fragment-based drug design Emphasizes the need for the in-depth biophysical characterization of protein targets as well as of therapeutic proteins, and for a thorough quality assessment of experimental structures Illustrates advances in the field of established therapeutic targets like kinases, serine proteinases, GPCRs, and epigenetic proteins, and of more challenging ones like protein-protein interactions and intrinsically disordered proteins

The determination of the three-dimensional structure of a biological molecule is the starting point in the understanding of molecular mechanisms involved in its complex biochemical reactions. The molecular architecture of multimolecular systems such as membranes and chromosomes provides the key to the fascinating field of molecular biology. Stereochemical details of biological macromolecules and their interactions with pharmacological agents form the basis for drug design. Naturally, the study of the structure and function of biological molecules has aroused tremendous interest and investigations in this area are being carried out in a large number of laboratories. The techniques used for this purpose include both experimental methods (X-ray and neutron diffraction measurements, study of NMR, ESR, vibrational and electronic spectra, ORD, CD and dipole moment measurements, biochemical modifications etc. ) and the oretical methods (quantum mechanical and classical potential energy calculations, Monte Carlo simulations and molecular graphics). F or several years now, X-ray diffraction [1] has served as our only source of infor mation on the three-dimensional arrangements of atoms in biopolymers. Fiber-diffrac tion of DNA led to the proposal of the DNA double helix. Fibers of long~hain polymers show ordering in the direction of the fibre-axis but not in the transverse plane. Accurate estimates of the dimensions of helical structures can be made using techniques on the basis of which models of biopolymers can be constructed.

Building on the success of the previous editions, the Textbook of Drug Design and Discovery, Fifth Edition, has been thoroughly revised and updated to provide a complete source of information on all facets of drug design and discovery for students of chemistry, pharmacy, pharmacology, biochemistry, and medicine. The information is presented in an up-to-date review form with an underlying and fundamental focus on the educational aspects. Beginning with an introduction to drug design and discovery, the first eight chapters cover molecular recognition, ligand-based drug design, and biostructure-based drug design. The authors also discuss drug-like properties and decision making in medicinal chemistry, chemical biology, natural products in drug discovery, and in vivo imaging in drug discovery. The middle six chapters provide an overview of peptide and protein drug design, prodrugs in drug design and development, and enzyme inhibitors. The authors also go through receptors (structure, function, and pharmacology), ion channels (structure and function), and neurotransmitter transporters (structure, function, and drug binding). The following chapters address important neurotransmitter systems, GABA and glutamic acid receptors and transporter ligands, acetylcholine, histamine, dopamine and serotonin, and opioid and cannabinoid receptors. The book concludes with an examination of neglected diseases, anticancer agents, tyrosine kinase receptors, and antibiotics.
