Book Description
Introduction to Biological and Small Molecule Drug Research and Development provides, for the first time, an introduction to the science behind successful pharmaceutical research and development programs. The book explains basic principles, then compares and contrasts approaches to both biopharmaceuticals (proteins) and small molecule drugs, presenting an overview of the business and management issues of these approaches. The latter part of the book provides carefully selected real-life case studies illustrating how the theory presented in the first part of the book is actually put into practice. Studies include Herceptin/T-DM1, erythropoietin (Epogen/Eprex/NeoRecormon), anti-HIV protease inhibitor Darunavir, and more. Introduction to Biological and Small Molecule Drug Research and Development is intended for late-stage undergraduates or postgraduates studying chemistry (at the biology interface), biochemistry, medicine, pharmacy, medicine, or allied subjects. The book is also useful in a wide variety of science degree courses, in post-graduate taught material (Masters and PhD), and as basic background reading for scientists in the pharmaceutical industry. For the first time, the fundamental scientific principles of biopharmaceuticals and small molecule chemotherapeutics are discussed side-by-side at a basic level Edited by three senior scientists with over 100 years of experience in drug research who have compiled the best scientific comparison of small molecule and biopharmaceuticals approaches to new drugs Illustrated with key examples of important drugs that exemplify the basic principles of pharmaceutical drug research and development

Book Description
Successful drugs have a good return on investment by bringing in considerably more revenue than the expenses of discovery, development, and manufacturing. Successful drugs pay for all drug projects, those that fail and those that have yet to fail or succeed. Most research and development (R&D) projects fail. Since R&D is the future of the company, a lot is at stake in the business of R&D. This chapter considers the organization of biopharmaceutical R&D, as well as various organizational experiments, that are already under way, that deal with the enormous risk and cost of biopharmaceutical R&D. There is a fairly uniform sequence of events involved in the discovery and development of biopharmaceuticals. The Stage-Gate Organization of the project pipeline is described along with stage-related goals. The high attrition in the industry is examined as well as reasons for project failure, particularly in the clinic. The fact that most projects fail in the biopharmaceutical industry means that risk, the probability that a project will fail, influences a number of key behaviours in biopharmaceutical R&D. The manner in which risk influences probability of success, cost, value and corporate commitment is considered. Not all discoveries occur within a company – many are in-licenced. Reduced revenues challenge a company's ability to develop all its assets, increasing the demands on project and portfolio management, and for out-licencing or partnering. In large biopharmaceutical companies, resource tends to be organized into business units, therapy areas, line departments, and platform technology groups. In the new era of reduced profits many companies are moving away from vertical integration towards decentralization, performing many to most functions in other companies, and in the extreme, towards virtual drug discovery and development. The risks and benefits with the external allocation of resource via outsourcing and partnering are discussed. Experiments with the organizational model of biopharmaceutical R&D are explored which aim to reduce risk, increase success and efficiency, including attempts to be big and small at the same time, planning for failure, and open innovation. There are also external revenue challenges, including generics competition and third-party payer constraints. On the upside are a number of opportunities to increase revenue, including new biologics and new areas of exploration – epigenetics and gene therapy – and by expanding markets into rapidly developing countries. Managers face complex challenges to the business of biopharmaceutical R&D. But, regardless of the type of company or set of partnered companies, academic institutions and service organizations that perform biopharmaceutical R&D, to a large extent the sequence of events in which a drug is discovered and developed will always be the same. And as long as the industry can continue to find new therapies that positively impact the lives of patients, it will continue to be an exciting and challenging industry.

Book Description
Drug discovery of small molecules from target selection through to clinical evaluation is a very complex, challenging but rewarding area of drug discovery. There are many obstacles along the journey from initial hit-finding activities, through optimization of compounds and eventually to delivery of robust candidate drugs (CDs) for clinical evaluation. This chapter presents key issues and literature solutions with respect to the optimization of hits into CDs. Details of the key hit-finding activities namely high-throughput screening, virtual screening, natural products, fragment-based drug discovery and fast-follower approaches are discussed. Key aspects of compound quality such as lipophilicity, solubility, drug metabolism and pharmacokinetic, plasma protein binding and cytochrome P450 inhibition/induction are discussed as well as potential safety liabilities such as human ether-a-go-go related gene, genotoxicity and phospholipidosis, Finally successful hit-to-lead and lead optimization case studies are presented to illustrate and highlight the key principles.

Book Description
Small Molecule Drug Discovery: Methods, Molecules and Applications presents the methods used to identify bioactive small molecules, synthetic strategies and techniques to produce novel chemical entities and small molecule libraries, chemoinformatics to characterize and enumerate chemical libraries, and screening methods, including biophysical techniques, virtual screening and phenotypic screening. The second part of the book gives an overview of privileged cyclic small molecules and major classes of natural product-derived small molecules, including carbohydrate-derived compounds, peptides and peptidomimetics, and alkaloid-inspired compounds. The last section comprises an exciting collection of selected case studies on drug discovery enabled by small molecules in the fields of cancer research, CNS diseases and infectious diseases. The discovery of novel molecular entities capable of specific interactions represents a significant challenge in early drug discovery. Small molecules are low molecular weight organic compounds that include natural products and metabolites, as well as drugs and other xenobiotics. When the biological target is well defined and understood, the rational design of small molecule ligands is possible. Alternatively, small molecule libraries are being used for unbiased assays for complex diseases where a target is unknown or multiple factors contribute to a disease pathology. Outlines modern concepts and synthetic strategies underlying the building of small molecules and their chemical libraries useful for drug discovery Provides modern biophysical methods to screening small molecule libraries, including high-throughput screening, small molecule microarrays, phenotypic screening and chemical genetics Presents the most advanced chemoinformatics tools to characterize the structural features of small molecule libraries in terms of chemical diversity and complexity, also including the application of virtual screening approaches Gives an overview of structural features and classification of natural product-derived small molecules, including carbohydrate derivatives, peptides and peptidomimetics, and alkaloid-inspired small molecules

Book Description
Improving and Accelerating Therapeutic Development for Nervous System Disorders is the summary of a workshop convened by the IOM Forum on Neuroscience and Nervous System Disorders to examine opportunities to accelerate early phases of drug development for nervous system drug discovery. Workshop participants discussed challenges in neuroscience research for enabling faster entry of potential treatments into first-in-human trials, explored how new and emerging tools and technologies may improve the efficiency of research, and considered mechanisms to facilitate a more effective and efficient development pipeline. There are several challenges to the current drug development pipeline for nervous system disorders. The fundamental etiology and pathophysiology of many nervous system disorders are unknown and the brain is inaccessible to study, making it difficult to develop accurate models. Patient heterogeneity is high, disease pathology can occur years to decades before becoming clinically apparent, and diagnostic and treatment biomarkers are lacking. In addition, the lack of validated targets, limitations related to the predictive validity of animal models - the extent to which the model predicts clinical efficacy - and regulatory barriers can also impede translation and drug development for nervous system disorders. Improving and Accelerating Therapeutic Development for Nervous System Disorders identifies avenues for moving directly from cellular models to human trials, minimizing the need for animal models to test efficacy, and discusses the potential benefits and risks of such an approach. This report is a timely discussion of opportunities to improve early drug development with a focus toward preclinical trials.
