Book Description
Most biological processes including signal transduction via transcription factors are mediated through protein-protein interactions (PPIs). Deregulations of the proteins involved in these interactions have been implicated in contributing to disease progression. It is now well established that cancer can be the result of aberrant PPIs, either through the loss of an essential interaction or, through the overactivation of transcription factors. Thus, targeting transcription factors have become attractive molecular targets. The multi-faceted approach to medicinal chemistry that encompasses synthesis, computational analyses, biophysical and biological evaluations are demonstrated by the invention and production of small molecule inhibitors for two well-known protein targets, the transcription factor STAT5 and the ubiquitin E3 ligase MDM2. A structure based drug design (SBDD) strategy was utilized in the discovery of the first potent and selective inhibitor of the STAT5 protein with optimal metabolic stability. Throughout our efforts in establishing an inhibitor for STAT5, we investigated STAT5 isoforms and their roles in driving several malignancies within the body. A novel STAT5A isoform FP assay was developed and efforts were undertaken to identify an isoform selective inhibitor. A STAT5B selective compound was identified with similar potencies to our first generation lead 13a. With a newly discovered pharmacophore for STAT5, optimizations of the tripodal scaffold were carried out to reduce entropic costs to binding. A new class of benzodiazepines were produced, however, these compounds did not result in a favorable potency/selectivity profile for the STAT5 protein. The class of benzodiazepines was then reevaluated for the MDM2 target with promising preliminary in vitro evaluations. We have identified the first in class and best in class inhibitor for the STAT5 protein reported to date. With a favorable potency/selectivity profile and optimal metabolic stability, two lead compounds have the potential to become candidates for advanced preclinical trials as a STAT5-targeted therapeutic. In addition, these small molecule inhibitors can serve as research tools to investigate the knockdown of STAT5 function at the protein level.

Book Description
Oncogenic transcription factors are an increasingly important target for anticancer therapies. Inhibiting these transcription factors could allow tumour cells to be "reprogrammed", leading to apoptosis or differentiation from the malignant phenotype. As the use of kinase inhibitors is gradually declining, transcription factor inhibition is the next hot topic for oncology research and merits much attention. This book highlights recent progress in the development of small-molecule inhibitors of oncogenic transcription factors. It also presents the evidence that this important protein class can be modulated in a number of ways to develop novel classes of therapeutic agents. The broad range of aspects covered by the book is noteworthy and renders it enormously valuable. This title serves as a unique reference book for postgraduates, academic researchers and practitioners working in the fields of biochemistry, biotechnology, cell and molecular biology and bio-inorganic chemistry.

Book Description
One of the most exciting areas of cancer research now is the development of agents which can target signal transduction pathways that are activated inappropriately in malignant cells. The understanding of the molecular abnormalities which distinguish malignant cells from their normal counterparts has grown tremendously. This volume summarizes the current research on the role that signal transduction pathways play in the pathogenesis of cancer and how this knowledge may be used to develop the next generation of more effective and less toxic anticancer agents. Series Editor comments: "The biologic behavior of both normal and cancer cells is determined by critical signal transduction pathways. This text provides a comprehensive review of the field. Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Description
This is the third volume in the new World Health Organization series on histological and genetic typing of tumours. Tumours of the haematopoietic and lymphoid tissues are covered. This was a collaborative project of the European Association for Haematolpathology and the Society for Haematopathology and others. The WHO classification is based on the principles defined in the Revised European-American Classification of Lymphoid Neoplasms (REAL) classification. Over 50 pathologists from around the world were involved in the project and proponents of all major lymphoma and leukaemia classifications have agreed to accept the WHO as the standard classification of haematological malignancies. So this classification represents the first true world wide concensus of haematologic malignancies. Colour photographs, magnetic resonance and ultrasound images and CT scans are included.

Book Description
Kinase drug discovery remains an area of significant interest across academia and in the pharmaceutical industry. There are now around 13 FDA approved small molecule drugs which target kinases and many more compounds in various stages of clinical development. Although there have been a number of reviews/publications on kinase research, this book fills a gap in the literature by considering the current and future opportunities and challenges in targeting this important family of enzymes. The book is forward-looking and identifies a number of hot topics and key areas for kinase drug discovery over the coming years. It includes contributions from highly respected authors with a combined experience in the industry of well over 200 years, which has resulted in a book of great interest to the kinase field and across drug discovery more generally. Readers will gain a real insight into the huge challenges and opportunities which this target class has presented drug discovery scientists. The many chapters cover a wide breadth of topics, are well written and include high quality colour and black and white images. Topics covered include an outline of how medicinal chemistry has been able to specifically exploit this unique target class, along with reflections on the mechanisms of kinases inhibitors. Also covered is resistance to kinase inhibitors caused by amino acid mutations, case studies of kinase programs and reviews areas beyond protein kinases and beyond the human kinome. Also described are modern approaches to finding kinase leads and the book finishes with a reflection of how kinase drug discovery may progress over the coming years.
