This book was released on 2012-09-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in chemical entities capable of blocking or modifying cell metabolism ultimately goes back to the discovery of the structure of DNA in the 1950s. Understanding of the biochemical processes involved in cell metabolism rapidly led to the idea that compounds could be designed which might interfere with these processes, and thus could be used in the treatment of the diseases caused by viral infection. Since then, several classes of drugs have been discovered which depend for their effect on modification of the proper functioning of nucleic acids and, with the introduction of acyclovir for the treatment of Herpes infections, nucleoside analogues have become the cornerstone of antiviral chemotherapy. The success of the early nucleoside agents, the toxicity and metabolic instability of many nucleoside analogues, and the effects of viral pathogens on public health are driving the design, synthesis and evaluation of new nucleoside analogues, with much attention turning to nucleosides containing `non natural' sugar analogues. This book focuses on the development of these agents, and draws together all the available material in an easily consulted form, which at the same time guides the reader into the research literature on the subject. Written primarily for the medicinal chemist, coverage includes both synthetic strategies and outline guidance on the main trends in biological activity. Particular attention is drawn to the comparison of synthetic routes to compounds with their natural analogues. Finally, the important antiviral activities of the compounds are treated, including anti-retrovirus, anti-hepadnavirus and anti-herpes virus properties. Written mainly for medicinal chemists in the pharmaceutical industry and synthetic organic chemists in academe, this book will also be attractive to researchers in institutions focusing on cellular metabolism. Advanced students of organic chemistry will find the clear discussion of the synthetic strategies adopted in the development of these compounds a useful introduction to this exciting and challenging area.

This book was released on 1985 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project was the synthesis of new candidate antiviral drugs for evaluation in the U.S. Army Medical Research Institute of Infectious Diseases Virus panel. Specifically, compounds were designed to resemble carbocyclic 3-deazaadenosine, our lead compound, in having the following characteristics: 1) a resemblance to adenine nucleosides, 2) little or no substrate activity for adenosine daminase, and 3) little or no substrate activity for any nucleoside kinases. The synthetic schemes employed involved the building up of the carbocyclic nucleosides from a cyclopentane precursor by condensation with an appropriate nitrogen heterocycle. Manipulations were then carried at the 5'-carbon of the carbocyclic nucleosides. Several compounds were prepared and submitted for testing, and chemistry leading to a larger series was developed, such that these other compounds can be prepared in the near future.

Available in PDF, EPUB and Kindle. Book excerpt: Due to the worldwide epidemic of acquired immunodeficiency syndrome (AIDS), the past ten years have witnessed a flurry of activity in the chemotherapy of viral diseases. Unprecedented scientific efforts have been made by scientists and clinicians to combat infections of human immunodeficiency virus (HIY), the causative agent. Looking back over the past ten years, we have made remarkable progress toward the treatment of the viral disease: isolation of HIV only two years after the identification of the disease, plus major strides in the areas of the molecular biology and virology of the retrovirus, etc. More remarkably, the discovery of the chemotherapeutic agent AZT (Retrovir) was made within two years after the isolation and identification of the virus, followed by unprecedented drug development efforts to culminate in the FDA approval of AZT in twenty-three months, which was a record-breaking time for approval of any drug for a major disease. The last six to seven years have particularly been an exciting and productive period for nucleoside chemists. Since the activity of AZI' was established in 1985, nucleoside chemists have had golden opportunities to discover additional anti-HIV nucleosipes, which are hoped to be less toxic and more effective than AZT, and the opportunity continues. As we all are aware, AZT possesses extremely potent anti-HIY activity, and no other nucleoside or non nucleoside has surpassed the potency of AZT in vitro.
Download or read book Advances in Antiviral Drug Design written by E. De Clercq and published by Elsevier. This book was released on 1996-04-23 with total page 249 pages. 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: Modern Applications of Cycloaddition Chemistry examines this area of organic chemistry, with special attention paid to cycloadditions in synthetic and mechanistic applications in modern organic chemistry. While many books dedicated to cycloaddition reactions deal with the synthesis of heterocycles, general applications, specific applications in natural product synthesis, and the use of a class of organic compounds, this work sheds new light on pericyclic reactions by demonstrating how these valuable tools elegantly solve synthetic and mechanistic problems. The work examines how pericyclic reactions have been extensively applied to different chemistry areas, such as chemical biology, biological processes, catalyzed cycloaddition reactions, and more. This work will be useful for organic chemists who deal with organic chemistry, medicinal chemistry, agrochemistry and material chemistry. Provides details on the synthesis of antiviral and anticancer compounds, marking the key role of unconventional catalyzed cycloaddition reactions for preparing new derivatives in a unique reaction pathway that is scalable in industrial processes Contains the most up-to-date review of the use of pericyclic reactions in drug delivery Includes the enzyme-catalyzed processes involving cycloaddition reactions for different targets, demonstrating that cycloaddition is more common in nature than expected Features new applications for cycloadditions in material chemistry and provides a general view of the most recent results in the area
