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.

Book Description
Considerable advances have been made in the treatment of antiviral diseases over the last decade. Several new drugs have been introduced while new clinical information has been gathered on the efficacy of existing drugs. This study aims to provide an examination of the basic science (drug formulae, structure and biochemical activity) and clinical information (usage and efficacy) on chemotherapy, as well as describing future potentials.

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
While adenosine triphosphate (ATP) is described as the universal currency of energy in all living organisms at the cellular level, the actual power lies in its phosphate tail. This book is the first dedicated to the field of nucleoside triphosphate (NTP). Its 13 chapters encompass the contributions of twenty scientists from both academia and industry. It provides collective information on the chemical, physiochemical, and biological properties of both natural and modified NTP and their application in life sciences. Three chapters review families of enzymes that depend on nucleotides for assembling DNA and RNA molecules. The appendix includes supporting NMR data.

Book Description
In June 1993 a clinical trial of fialuridine (FIAU), a promising new medication for hepatitis B, was abruptly terminated when one of the 15 out-patients participating in the National Institutes of Health (NIH) study was suddenly hospitalized with liver failure. Although all the remaining patients were contacted and told to stop taking their medication, six more subsequently developed severe toxicity. Five patients died, and two others were probably saved from death only by having liver transplants. In response to a request from the Secretary of the Department of Health and Human Services, the IOM committee has analyzed the FIAU clinical trials, making recommendations for additional safeguards for the conduct of future clinical trials. This evaluation included the review of documents pertaining to investigational new drug submissions, protocols and consent forms from other clinical trials, as well as information available from other clinical and preclinical experience with compounds related to FIAU and its parent drug, fiacitibine (FIAC), which is metabolized to FIAU. The committee does not seek to affix responsibility for the adverse outcome of this NIH trial, but instead focuses on whether any rules or procedures governing the clinical trials process itself need to be changed, and if so, what burdens or costs such changes might place on future clinical trials.

Book Description
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
