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 Nucleoside Analogues written by R. T. Walker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains the Review Lectures given at a joint NATO Advanced Study Institute and a FEB S Advanced Study Course, held at Sogesta (Nr. Urbino), Italy from the 7th - 18th May 1979. The Course entitled "Nucleoside Analogues : Chemistry, Biology and Medical Applications" was held for several reasons. In the past few years, many useful and potentially-useful nucleoside analogues have either reached the stage of clinical use or are undergoing clinical trials. Many more compounds have been synthesised by the organic chemist and little more has been done with them other than possibly a few perfunctory biological tests. This is often due to either a lack of interest or an inadequate knowledge of the testing proced ures available or a lack of communication between the chemist, biochemist, pharmacologist and the clinician such that few compounds receive the testing and evaluation which they deserve. The aim of this meeting was to gather together many of the experts in the different scientific disciplines which are involved in the design, synthesis, testing and clinical use of nucleoside analogues, primarily as anti-viral and anti-cancer agents, and to discuss in depth the fundamental principles of each discipline so that participants could understand each other's problems and be more aware of the information required and that which can be obtained.

This book was released on 2007 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second project, the synthesis of three series of bis-aminochloropyrimidine derivatives with different types of linkers as potential DNA intercalators is described. The first series are aminochloropyrimidines bridged by polymethylene chain linkers with various lengths. The second series are bridged by polyether linkers to lower the lipophilicity. The third series are bridged by linkers containing benzene rings to limit the flexibility. The spectral data and other physical properties of the new compounds are discussed. The preliminary screening results indicate that many new synthesized bis-intercalators are biologically active. The relationship between bioactivity and structure is discussed as well.

This book was released on 2007-11-07 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful cancer chemotherapy relies heavily on the application of various deoxynucleoside analogs. Since the very beginning of modern cancer chemotherapy, a number of antimetabolites have been introduced into the clinic and subsequently applied widely for the treatment of many malignancies, both solid tumors and hematological disorders. In the latter diseases, cytarabine has been the mainstay of treatment of acute myeloid leukemia. Although many novel compounds were synthesized in the 1980s and 1990s, no real improvement was made. However, novel technology is now capable of elucidating the molecular basis of several inborn errors as well as some specific malignancies. This has enabled the synthesis of several deoxynucleoside analogs that could be applied for specific malignancies, such as pentostatin and subsequently chlorodeoxyadenosine (cladribine) for the treatment of hairy cell leukemia. Already in the early stage of deoxynucleoside analog development, it was recognized that several of these compounds were very effective in the treatment of various viral infections, such as for the treatment of herpes infections. This formed the basis initially for the design of azidothymidine and subsequently many other analogs, which are currently successfully used for the treatment of HIV infections. As a spin-off of these research lines, some compounds not eligible for development as antiviral agents appeared to be very potent anticancer agents. The classical example is gemcitabine, now one of the most widely applied deoxynucleoside analogs, used for the (combination) treatment of non-small cell lung cancer, pancreatic cancer, bladder cancer, and ovarian cancer.
