This book was released on 2013-06-29 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This pUblication contains the Review Lectures presented at a joint NATO Advanced Study Institute and FEES Advanced Study Course held at Les Arcs, Bourg-8aint-Maurice, France, from the 19th June - 2nd July 1983. The Course, entitled "Targets for the Design of Antiviral Agents" was in some ways a sequel to the NATO-FEES Course held at SOGESTA (near Urbino), Italy from the 7th - 18th May 1979 and published as volume A26 in this series. During the subsequent four years, we have witnessed the first of the "new generation" of antiviral compounds, which are more efficacious and less toxic than the "classical" antiviral drugs, reach the clinic and we felt that it w~s the right time to assess the future prospects of this verY important and exciting field. The vast majority of the drugs developed recently have proved active against various members of the herpesvirus family and elsewhere in this publication we learn that the cure for only rather few viral diseases, such as the common cold, influenza and herpes, promises the return on investment required by the pharmaceutical industry. However, the aim of this Course was for eminent virologists to identify possible targets among the various virus classes against which the chemists could then design suitable therapeutic agents. Recent advances with antiherpesvirus drugs have shown that a far greater selectivity and therapeutic index can be obtained than was previously thought to be possible.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the series on Advances in Antiviral Drug Design is to regularly review the "state of the art" on emerging new developments in the antiviral drug research field, thereby spanning the conceptual design and chemical synthesis of new antiviral compounds, their structure-activity relationship, mechanism and target(s) of action, pharmacological behavior, antiviral activity spectrum, and therapeutic potential for clinical use. Volume 2 begins with a description of the antiviral potential of antisense oligonucleotides by J. Temsamani and S. Agrawal. According to the aims of the anitsense technology, these oligonucleotides should be targeted at specific viral antisense technology, these oligonucleotides should be targeted at specific viral mRNA sequences so that translation to the virus-specified proteins is blocked; this has been achieved for a number of oligomers, some of which are now in clinical trials for the treatment of HIV, HCMV, and human papilloma virus (HPV) infections. Then C.-S. Yuan, S. Liu, S.F. Wnuk, M.J. Robins and R.T. Borchardt assess the role of S-adenosylhornocysteine (AdoHcy) hydrolase as target for the design of antiviral agents with broad-spectrum antiviral activity. This is followed by an in-depth account on the design and synthesis of a number of first-, second- and third-generation AdoHcy hydrolase inhibitors and their mode of action at the enzyme level. V.E. Marquez provides a comprehensive description of the various carbocyclic (carba) nucleosides that have been synthesized and evaluated for antiviral activity. Although the number and diversity of the carba-nucleosides that have been found to be antivirally active (or inactive) is astonishingly high, there is no limit to further expansion of this fascinating class of molecules. For the various nucleoside analogues that have to be intracellularly phosphorylated to the 5'-triphosphate stage, to interact with their target enzyme (i.e., herpesviral DNA polymerase or retroviral revers transcriptase) the first phosphorylation step is often the rate-limiting step, and thus various strategies are envisaged by C. Perigoud, J.-L. Girardet, G. Gosselin and J.-L. Bach on how to bypass this initial phosphorylation and to deliver the nucleoside 5'-monophophate directly inside the cells. The HIV protease has been considered as a paradigm for rational drug design. The enzyme is among the best understood in terms of both structure and action, and because of its crucial role in the maturation of HIV, it has been vigorously pursued as a target for anti-HIV chemotherapy. In their comprehensive review of the multidisciplinary approach towards the development of HIV protease inhibitors A.G. Tomasselli, S. Thaisrivongs and R.L. Heinrikson highlight those protease inhibitors which have been brought forward to clinical trials.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes state-of-the-art antiviral drug design and discovery approaches starting from natural products to de novo design, and provides a timely update on recently approved antiviral drugs and compounds in advanced clinical development. Special attention is paid to viral infections with a high impact on the world population or highly relevant from the public health perspective (HIV, hepatitis C, influenza virus, etc.). In these chapters, limitations associated with adverse effects and emergence of drug resistance are discussed in detail. In addition to classical antiviral strategies, chapters will be dedicated to discuss the non-classical drug development strategies to block viral infection, for instance, allosteric inhibitors, covalent antiviral agents, or antiviral compounds targeting protein–protein interactions. Finally, current prospects for producing broad-spectrum antiviral inhibitors will be also addressed. The book is distinctive in providing the most recent update in the rapidly evolving field of antiviral therapeutics. Authoritative reviews are written by international scientists well known for their contributions in their topics of research, which makes this book suitable for researchers not only within the antiviral research community but also attractive to a broad audience in the drug discovery field. This book covers molecular structures and biochemical mechanisms mediating the antiviral effects, while discussing various ligand design strategies, which include traditional medicinal chemistry, computational chemistry, and chemical biology approaches. The book provides a comprehensive review of antiviral drug discovery and development approaches, particularly focusing on current innovations and future trends.

Download or read book Human Herpesviruses written by Ann Arvin and published by Cambridge University Press. This book was released on 2007-08-16 with total page 1325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

Download or read book Advances in Antiviral Drug Design written by E. De Clercq and published by Elsevier. This book was released on 2003-12-17 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth volume of Advances in Antiviral Drug Design is keeping up with the recent progress made in the broad field of antiviral drug research and encompasses six specific directions that have opened new avenues for the treatment of HIV and other virus infections. First, as the introductory chapter, the different new anti-HIV agents that are now in preclinical or clinical development are reviewed by E. De Clercq. This includes new NRTIs, NNRTIs and PIs, but also HIV entry/fusion inhibitors as well as integrase inhibitors, and some of these agents, such as the NRTI emtricitabine [(-)FTC] and the PI atazanavir, may soon be licensed for clinical use. Second, high expectations are vested in the potential therapeutic usefulness of inhibitors of HIV integration, a point of no return in the life cycle of HIV, and this approach is highlighted by D.J. Hazuda and S.D. Young. Third, as all currently available PIs can be described as "peptidomimetic", and, therefore, expected to demonstrate overlapping virus-drug resistance and side effect profiles, it would be interesting to see how a non-peptidic protease inhibitor such as tipranavir behaves, and this is covered by D. Mayers, K. Curry, V. Kohlbrenner and S. McCallister. Fourth, neuraminidase inhibitors such as zanamivir (that has to be inhaled) and oseltamivir (that can be administered via the oral route) have gained a definitive status as antiviral drugs useful for both therapy and prophylaxis of influenza A and B virus infections; as they target a specific influenza viral enzyme, neuraminidase (or sialidase), they may be expected to block newly emerging influenza viruses as well, and the design of neuraminidase inhibitors has received due attention of H. Jin and C.U. Kim. Fifth, while the major current efforts in antiviral drug development have shifted from herpesviruses towards HIV and hepatitis viruses [hepatitis B virus (HBV), hepatitis C virus (HCV)], it is interesting to note that by switching from the classical five-membered sugar or acyclic nucleoside strategy, J. Wang, M. Froeyen and P. Herdewijn have gone "upstream" in designing six-membered carbocyclic nucleosides as potential anti-herpesvirus agents. Sixth, following up on the nucleotide prodrug strategy introduced above under ix, to deliver the biologically active nucleotides inside the cells, C. Meier has elaborated on a particular class of such pronucleotides, namely that of the cyclosaligenyl pronucleotides, an approach that should have far reaching implications for compounds effective against HIV, HBV and other viruses. The six topics covered in this fourth volume of Advances in Antiviral Drug Design are in the front line of the present endeavors towards the design and development of new therapeutic agents for virus infections. They pertain to the combat against three of the most important viral pathogens of current times: HIV, HBV, influenza virus and herpesviruses.

Download or read book Successful Strategies for the Discovery of Antiviral Drugs written by Manoj C. Desai and published by Royal Society of Chemistry. This book was released on 2013-06-17 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The antiviral therapeutic area continues to rapidly generate meaningful new chemical entities; for example, for HIV alone more than 25 drugs have been approved, and in the next few years many individual drugs and single tablet regimens will be approved for the treatment of hepatitis C virus infection. The increasing success in the antiviral area could be due to targeting drugs at "non-self" genomes and to the patient population that is tolerant of manageable side effects and adaptable to inconvenient dosing. Aimed at medicinal chemists and emerging drug discovery scientists, the book is organized according to the various strategies deployed for the discovery and optimization of initial lead compounds. This book focuses on capturing tactical aspects of problem solving in antiviral drug design, an approach that holds special appeal for those engaged in antiviral drug development, but also appeals to the broader medicinal chemistry community based on its focus on tactical aspects of drug design.

Download or read book Viral Polymerases written by Satya Prakash Gupta and published by Academic Press. This book was released on 2018-10-29 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viral Polymerases: Structures, Functions and Roles as Antiviral Drug Targets presents in-depth study information on the structure and functions of polymerases and their roles in the lifecycle of viruses, and as drug targets. Viral polymerases constitute a vital component in the lifecycle of many viruses, such as human immunodeficiency virus (HIV), hepatitis viruses, influenza virus, and several others. They are essentially required for the replication of viruses. Thus, the polymerases that can be found in viruses (called viral polymerases) represent favorable targets for the design and development of antiviral drugs. Provides comprehensive, state-of-the-art coverage on virus infections, the virus lifecycle, and mechanisms of polymerase inhibition Analyzes the structure-activity relationships of inhibitors of each viral polymerase Presents a consistent and comprehensive coverage of all aspects of viral polymerases, including structure, function and their role as antiviral drug targets

Download or read book Design of Anti AIDS Drugs written by Erik De Clercq and published by Elsevier Publishing Company. This book was released on 1990 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several steps in the replicative cycle of human immunodeficiency virus (HIV) that could be considered as adequate targets for chemotherapeutic intervention, e.g., virus attachment to the cells, virus penetration and uncoating, transcription of the viral (RNA) genome to proviral DNA, integration of the proviral DNA into host cell DNA, transcription of the proviral precursor proteins to mature viral proteins, assembly and release ('budding') of the viral particles. These processes depend on, and are regulated by, specific viral proteins. This makes many of these processes and proteins plausible targets for the design of selective inhibitors. The contributions assembled in this book are aimed at presenting what is known anno 1990 about (1) the different steps in the HIV replicative cycle that could be considered as targets for anti-HIV agents, (2) the compounds that interact with these targets and offer promise as candidate drugs for the treatment of HIV infection, and (3) to the extent that it has been resolved, the mechanism of interaction of the anti-HIV agents with their putative targets.

Download or read book Antiviral Strategies written by Hans-Georg Kräusslich and published by Springer Science & Business Media. This book was released on 2008-12-02 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crucial issue for antiviral therapy is the fact that all antiviral substances rapidly select for resistance; thus, monitoring and overcoming resistance has become a most important clinical paradigm of antiviral therapy. This calls for cautious use of antiviral drugs and implementation of combination therapies. In parallel, efforts in drug discovery have to be continued to develop compounds with novel mode-of-action and activity against resistant strains. This book reviews the current status of antiviral therapy, from the roads to development of new compounds to their clinical use and cost effectiveness. Individual chapters address in more detail all available drug classes and outline new approaches currently under development.

Download or read book Structure and Physics of Viruses written by Mauricio G. Mateu and published by Springer Science & Business Media. This book was released on 2013-06-04 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contemplates the structure, dynamics and physics of virus particles: From the moment they come into existence by self-assembly from viral components produced in the infected cell, through their extracellular stage, until they recognise and infect a new host cell and cease to exist by losing their physical integrity to start a new infectious cycle. (Bio)physical techniques used to study the structure of virus particles and components, and some applications of structure-based studies of viruses are also contemplated. This book is aimed first at M.Sc. students, Ph.D. students and postdoctoral researchers with a university degree in biology, chemistry, physics or related scientific disciplines who share an interest or are actually working on viruses. We have aimed also at providing an updated account of many important concepts, techniques, studies and applications in structural and physical virology for established scientists working on viruses, irrespective of their physical, chemical or biological background and their field of expertise. We have not attempted to provide a collection of for-experts-only reviews focused mainly on the latest research in specific topics; we have not generally assumed that the reader knows all of the jargon and all but the most recent and advanced results in each topic dealt with in this book. In short, we have attempted to write a book basic enough to be useful to M.Sc and Ph.D. students, as well as advanced and current enough to be useful to senior scientists with an interest in Structural and/or Physical Virology.
