It covers a wide range of information, including data from 3 studies of theoretical, molecular and cellular pharmacology, signal transduction, integrative physiology, new drug discoveries and clinical applications. It fills an important gap in the literature since no alternative source of such information is currently available. Although the A receptor is increasingly being recognized for 3 its increasing number of biological roles throughout the body and many A receptor 3 ligands have proven useful in elucidating peripheral and central pathologies, many issues remain unresolved. Moreover, research activity in this field continues to grow exponentially, resulting in a constant flow of new information. The chapters in this book cover both basic science and the relevant applications and provide an authoritative account of the current status of the field. They have enabled my goal as editor to make “A Adenosine Receptors from Cell Biology to Pharmacology and 3 Therapeutics” an up to date, scientifically excellent, reference source, attractive to basic and clinical scientists alike, a reality. Detailed understanding of the physico-chemical aspects and molecular biology of the A receptor provides a solid basis for its future development as a target for 3 adenosine-based pharmacotherapies (Chapters 2 and 3). Recognition and charac- terization of intracellular pathways modulated by A receptor activation supports 3 the belief that modulating these signaling routes is likely to lead to considerable advances in the management of many diseases (Chapters 4 and 5). The identifica- tion of new potent and selective A receptor ligands opens new frontiers for the 3 elucidation of the therapeutic potential arising from stimulating or blocking the A 3 receptor (Chapters 1, 6, 7 and 8). The A receptor appears to play a prominent role 3 under ischemic conditions and remains a promising target for promoting angio- genesis and treating neurodegenerative diseases associated with acute ischemia (Chapter 9). In terms of clinical utility, it will be critical to explore in greater detail the efficacy of the A receptor-mediated protective response in diseased hearts, 3 particularly with respect to diabetes, hypertension, hypertrophy, and dyslipidemias (Chapters 10 and 14). The important protective role of the adenosine A receptor, 3 originally discovered in studies of ischemia-reperfusion injury in the heart, has now been extended to skeletal muscle (Chapter 13). The importance of eosino- phils in allergy and asthma is well recognized and targeting the A receptor for the 3 v vi Preface treatment of eosinophil-dependent pulmonary diseases such as asthma, chronic obstructive pulmonary disease and rhinitis offers realistic hope of novel therapies (Chapters 1 and 11). A receptors are present in many immune cells and are 3 involved in the regulation of inflammatory and immune processes, suggesting new therapeutic strategies may emerge for inflammatory conditions such as sepsis, asthma and autoimmune disorders including rheumatoid arthritis, Crohn’s disease and psoriasis (Chapter 12). The oral bioavailability of certain A agonists and 3 encouraging data from early clinical studies support the development of these agents as anti-rheumatic drugs (Chapter 15). The effectiveness of the A receptor 3 agonist, Cl-IB-MECA, in several animal tumor models led to the introduction of this molecule into a program of pre-clinical and clinical studies. The excellent safety profile led to the initiation of clinical studies in patients with hepatocellular carcinoma which are currently ongoing. Paradoxically, it appears that A receptor 3 antagonists can also be considered promising in the treatment of human cancer (Chapter 16). These exciting results arising from the hard work of the people associated with this book hold promise for a future generation of new drugs for the treatment of important diseases. I would like to express my gratitude to the distinguished contributors who have expressed their confidence in this book by contributing to it and who will be key players in the success of the research on A receptors in the future. 2011–2012 will 3 mark the 20th anniversary of the cloning of the A receptor. It would give me enor- 3 mous pleasure if new molecules targeting the A receptor could become drugs at 3 this time with the help and participation of the eminent scientists who have authored this book. I would also like to thank very sincerely the Publishing Editor of Springer Biomedicine, Dr. Max Haring. It has been a pleasure working with him in this project. I am also extremely grateful for the critical contributions by Dr. John Fozard who has played a key role in the entire project. Last, but certainly not least, I wish to thank the members of my Research Group for their scientific work in the field of A adenosine receptors. 3 The first edition of “A Adenosine Receptors from Cell Biology to Pharmacology 3 and Therapeutics” volume is dedicated to my wife Cristina and to all the friends and colleagues who contributed to this book.
