Nanotechnology Methods for Neurological Diseases and Brain Tumors: Drug Delivery across the Blood-Brain Barrier compiles the latest (and future potential) treatment strategies for brain tumors and neurological diseases, in particular Alzheimer's, Parkinson's and stroke, those that bypass the blood/brain barrier. The current understanding of brain drug delivery and access is discussed in Chapter One, with the next section focusing on the implementation of the nose-to-brain intranasal route in brain-targeted drug delivery. In addition, nanotechnology-based brain drug delivery is covered in Chapter Three. This avenue offers impressive improvement in the treatment of neurological diseases and brain tumors by using bio-engineered systems that interact with biological systems at a molecular level. In Chapter Four, emphasis is placed on the need for brain-targeted experimental models that mimic disease conditions. Final chapters discuss the very latest advances in targeted treatment strategies for neurological diseases and brain tumors.

Medicinal chemistry is both science and art. The science of medicinal chemistry offers mankind one of its best hopes for improving the quality of life. The art of medicinal chemistry continues to challenge its practitioners with the need for both intuition and experience to discover new drugs. Hence sharing the experience of drug research is uniquely beneficial to the field of medicinal chemistry. Drug research requires interdisciplinary team-work at the interface between chemistry, biology and medicine. Therefore, the topic-related series Topics in Medicinal Chemistry covers all relevant aspects of drug research, e.g. pathobiochemistry of diseases, identification and validation of (emerging) drug targets, structural biology, drugability of targets, drug design approaches, chemogenomics, synthetic chemistry including combinatorial methods, bioorganic chemistry, natural compounds, high-throughput screening, pharmacological in vitro and in vivo investigations, drug-receptor interactions on the molecular level, structure-activity relationships, drug absorption, distribution, metabolism, elimination, toxicology and pharmacogenomics. In general, special volumes are edited by well known guest editors.

The availability of various in vitro and in vivo techniques has considerably advanced the research on drug transport and metabolism across the blood-brain barrier (BBB). These specialized and sophisticated experimental strategies are of fundamental importance if one is to gain a greater understanding of enhanced and selective drug delivery to the brain. The reader will find in this book methods for in vitro endothelial/astrocyte cell culture models, and for in vivo intracerebral microdialysis to study drug tranport across the BBB. This book, however, is not merely a laboratory manual consisting of recipes for BBB research; it permits the presentation of the different methods in fine detail, revealing tricks and short cuts that frequently do not appear in the literature. The researcher is well aware that differences (subtle or otherwise) in experimental steps used in different laboratories may influence the outcome of any particular procedure. The book also illustrates the accessibility and the application of the different methods in different species. Background information of the protocol is given in every chapter, which also contains a literature list that the reader may wish to refer to for further information. This volume will be invaluable to basic researchers as well as to those involved in the search for agents suitable for pharmaceutic intervention in the central nervous system.

The development of new CNS drugs is notoriously difficult. Drugs must reach CNS target sites for action and these sites are protected by a number of barriers, the most important being the blood –brain barrier (BBB). Many factors are therefore critical to consider for CNS drug delivery, e.g. active/passive transport across the BBB, intra-brain distribution, and central/systemic pharmacokinetics, to name a few. Neurological disease and trauma conditions add further complexity because CNS barriers, drug distribution and pharmacokinetics are dynamic and often changed by disease/trauma. Knowledge of all these factors and their interplay in different conditions is of utmost importance for proper CNS drug development and disease treatment. In recent years much information has become available for a better understanding of the many factors important for CNS drug delivery and how they interact to affect drug action. This book describes small and large drug delivery to the brain with an emphasis on the physiology of the BBB and the principles and concepts for drug delivery across the BBB and distribution within the brain. It contains methods descriptions for studying drug delivery, routes and approaches of administering drugs into the brain, the influence of disease, and drug industry perspectives. Therewith, it contributes to an in-depth understanding of the interplay between brain (patho)-physiology and drug characteristics. Furthermore, the content is designed to be both cutting-edge and educational, so that the book can be used in high-level training of academic and industry scientists with full references to original publications. ​

The vasculature of the central nervous system (eNS) is characterized by the existence of the blood-brain barrier (BBB), which can be regarded as both an anatomical and physiological phenomenon. The BBB is formed by a complex cellular system of endothelial cells, astroglia, pericytes, perivascular macrophages and a basal membrane, although the anatomic substrate of the BBB is the interendothelial tight junctions that form a continuous sealing. The BBB serves as an exquisitely controlled, functional gate to the eNS. It not only protects the brain from agents in the blood that could impair neurological function, but also controls the influx and efflux of numerous substances to maintain proper homeostasis and provide the brain with necessary nutrients. The structural and functional integrity of the BBB was shown to be dramatically altered during various diseases of the eNS, including neoplasia, ischemia, trauma, hypertension, inflammation and epilepsy. Recent years research has partially elucidated the mechanisms underlying the development of some of these brain disorders as well as the pathways used by different pathogens, like bacteria and viruses, to initiate eNS infections. The development of in vitro models of the BBB had instrumental role in the understanding of the involvement of the BBB in the pathogenesis of several eNS diseases. The intimate, functional association between the function of the brain and the activity of the BBB makes the later a target for pharmacological modulation that will expand the therapeutic possibilities for a range of neurological diseases.

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
