Available in PDF, EPUB and Kindle. Book excerpt: This book contains the scientific contributions presented at an International Symposium held in Sorrento, Italy, in June 1988 under the auspices of the University of Naples, the Italian Society of Biochemistry, and the National Research Council. The modern history of polyamines dates back to 1958 when the Tabors and Rosenthal first described the outlines of their biological synthesis. From then on, and particularly in the last ten years, a veri table explosion of Literature, characterized by thousands of papers, has witnessed the interest of the scientific community toward these molecules. Perhaps the old statement that "polyamines are molecules in search of a function" is no longer true today. A large number of effects exerted by these simple molecules are well known, and in many cases the mechanisms underlying these effects have been elucidated. The first section of the volume is entirely devoted to the enzymology and molecular biology of ornithine decarboxylase. Since its discovery by Gale more than forty years ago, this can be considered among the most widely studied enzymes in biology, and one of the most complex models in enzyme regulation. The mechanism of control of the enzyme activity at the transcriptional, post-transcriptional and post-translational levels, as well as the fine regulation by antizyme, are discussed in detail. The second group of contributions deals wi th AdoMet decarboxylase, propylamine transferase, polyamine oxidase and the other enzymes related to polyamine interconversion and regeneration.

This book was released on 2019-10-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyamines are ubiquitous polycations essential for all cellular life. The most common polyamines in eukaryotes, spermine, spermidine, and putrescine, exist in millimolar intracellular concentrations that are tightly regulated through biosynthesis, catabolism, and transport. Polyamines interact with, and regulate, negatively charged macromolecules, including nucleic acids, proteins, and ion channels. Accordingly, alterations in polyamine metabolism affect cellular proliferation and survival through changes in gene expression and transcription, translation, autophagy, oxidative stress, and apoptosis. Dysregulation of these multifaceted polyamine functions contribute to multiple disease processes, thus their metabolism and function have been targeted for preventive or therapeutic intervention. The correlation between elevated polyamine levels and cancer is well established, and ornithine decarboxylase, the rate-limiting biosynthetic enzyme in the production of putrescine, is a bona fide transcriptional target of the Myc oncogene. Furthermore, induced polyamine catabolism contributes to carcinogenesis that is associated with certain forms of chronic infection and/or inflammation through the production of reactive oxygen species. These and other characteristics specific to cancer cells have led to the development of polyamine-based agents and inhibitors aimed at exploiting the polyamine metabolic pathway for chemotherapeutic and chemopreventive benefit. In addition to cancer, polyamines are involved in the pathologies of neurodegenerative diseases including Alzheimer’s and Parkinson’s, parasitic and infectious diseases, wound healing, ischemia/reperfusion injuries, and certain age-related conditions, as polyamines are known to decrease with age. As in cancer, polyamine-based therapies for these conditions are an area of active investigation. With recent advances in immunotherapy, interest has increased regarding polyamine-associated modulation of immune responses, as well as potential immunoregulation of polyamine metabolism, the results of which could have relevance to multiple disease processes. The goal of this Special Issue of Medical Sciences is to present the most recent advances in polyamine research as it relates to health, disease, and/or therapy.

Available in PDF, EPUB and Kindle. Book excerpt: The state of the art in the area of polyamines is presented in this useful, two-volume publication. Basic information describing the role of polyamines in the processes of growth and differentiation is given. Also included are data on the regulation of polyamine biosynthesis and metabolism and their interactions with nucleic acids. Several chapters are devoted to the role of polyamines in various aspects of plant biology, with a special emphasis on their participation in the response of plants to extreme environments. Special attention is given to the use of inhibitors of polyamine biosynthesis as potential antitumor and antiproliferative agents. Additionally, recent progress in the molecular biology and genetic engineering of genes coding for polyamine biosynthetic enzymes is described. Cancer researchers, biologists, geneticists, biochemists, physiologists, and clinicians will find this volume indispensible. Contents VOLUME II: POLYAMINES IN MICROBES.

Available in PDF, EPUB and Kindle. Book excerpt: Spermine, spermidine, and putrescine constitute the mammalian polyamines, abundant polycations with essential roles in critical cell functions. As such, intracellular polyamine concentrations are tightly regulated through biosynthesis, catabolism, and transport. The multifaceted effects of polyamine dysregulation have contributed to its role in multiple disease processes but have also implicated it as target for preventive or therapeutic intervention. The correlation between oncogene-mediated elevation of polyamine biosynthesis and cancer is well established, and induced polyamine catabolism contributes to carcinogenesis that is associated with certain forms of chronic infection and/or inflammation. In addition to cancer, polyamines are involved in the pathologies of neurodegenerative diseases, parasitic and infectious diseases, wound healing, ischemia/reperfusion injuries, and certain age-related conditions, as polyamines concentrations are reported to decrease with age.

Download or read book Polyamine Drug Discovery written by Patrick Woster and published by Royal Society of Chemistry. This book was released on 2011-11-07 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyamines are ubiquitous molecules that are involved in a number of important cellular processes. Aberrations in their function or metabolism play a role in diseases such as cancer and parasitic infection. A number of validated drug targets have been identified, including enzymes in the polyamine biosynthetic and catabolic pathways and the S-adenosylmethionine synthetic and salvage pathways. Polyamine Drug Discovery is the first comprehensive volume to cover all aspects of the design and development of potential therapeutics targeting polyamine metabolism. The book details research progress from 1975 to the present date and discusses the design and use of polyamine metabolism inhibitors as therapeutic agents. Various polyamine-containing drugs are described that can be used in chemotherapy, and as treatments for infections including trypanosomiasis, leishmaniasis and malaria. Finally, the roles of polyamine analogues in chemoprevention, polyamine-containing vectors for gene delivery, and the design of polyamine-based epigenetic modulators are detailed. Each chapter addresses a different aspect of polyamine drug discovery and all are written by medicinal and biological chemists with particular expertise in developing agents that modulate polyamine metabolism or function. The book will increase the visibility of polyamine drug discovery among pharmaceutical researchers and provide a valuable reference for everyone working in the field.
