Book Description
Compiles current tested and proven approaches to synthesize novel nucleoside analogues Featuring contributions from leading synthetic chemists from around the world, this book brings together and describes tested and proven approaches for the chemical synthesis of common families of nucleoside analogues. Readers will learn to create new nucleoside analogues with desired therapeutic properties by using a variety of methods to chemically modify natural nucleosides, including: Changes to the heterocyclic base Modification of substituents at the sugar ring Replacement of the furanose ring by a different carbo- or heterocyclic ring Introduction of conformational restrictions Synthesis of enantiomers Preparation of hydrolitically stable C-nucleosides Chemical Synthesis of Nucleoside Analogues covers all the major classes of nucleosides, including pronucleotides, C-nucleosides, carbanucleosides, and PNA monomers which have shown great promise as starting points for the synthesis of nucleoside analogues. The book also includes experimental procedures for key reactions related to the synthesis of nucleoside analogues, providing a valuable tool for the preparation of a number of different compounds. Throughout the book, chemical schemes and figures help readers better understand the chemical structures of nucleoside analogues and the methods used to synthesize them. Extensive references serve as a gateway to the growing body of original research studies and reviews in the field. Synthetically modified nucleosides have proven their value as therapeutic drugs, in particular as antiviral and antitumor agents. However, many of these nucleoside analogues have undesirable side effects. With Chemical Synthesis of Nucleoside Analogues as their guide, researchers have a new tool for synthesizing a new generation of nucleoside analogues that can be used as therapeutic drugs with fewer unwanted side effects.

Book Description
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.

Book Description
A magisterial survey of all aspects of the reverse transcriptase inhibitors (RTIs) used to treat HIV/AIDS, including drug discovery, pharmacology, development of drug resistance, toxicity, and prevention of mother-to-child transmission of HIV/AIDS. The authors synthesize our current understanding of the role of reverse transcriptase in the viral life cycle, describe the discovery and development of eight nucleoside and nucleotide analogs that represent milestones in treatment history, and thoroughly discuss the question of toxicity and resistance to this class of drugs. They also address three non-nucleoside RTIs and their pharmacokinetics and comparative clinical efficacy, new RTIs currently under development, and the impact of approved agents on treatment, in general, and on vertical transmission in the developing world.

Book Description
Nucleosides, Nucleotides, and Their Biological Applications contains the proceedings of the Fifth International Round Table on Nucleosides, Nucleotides, and Their Biological Applications held at Research Triangle Park, North Carolina on October 20-22, 1982. Contributors focus on the biological applications of nucleosides and nucleotides, along with advances in synthetic chemistry. Topic range from fast-moving biochemical subjects such as the 2',5'-oligoadenylates and their relationship to interferons; adenosine and adenine nucleotide receptors; and nucleosides with selective antiviral action. This volume is organized into 11 chapters and begins with an overview of nucleosides that are used as antiviral agents and their mechanism of action, including idoxuridine, vidarabine, and trifluridine. The discussion then shifts to the chemical and biological properties of nucleosides of purines and ring analogs; 2'-fluoroarabinosyl pyrimidines and purine-like C-nucleosides; and the potential of 2',5'-oligoadenylates as chemotherapeutic agents. The reader is also introduced to receptors for adenosine and adenine nucleotides; the function of pyrrolo[2,3-d]pyrimidine nucleosides in polynucleotides; and unusual nucleoside synthons and oligonucleotide synthesis. A chapter on the synthesis of versatile C-nucleoside precursors and certain C-nucleosides concludes the book. This book will be of value to chemists, biologists, and those with an interest in nucleosides and nucleotides.

Book Description
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.
