In Vitro Bioassay Techniques for Anticancer Drug Discovery and Development | Taylor & Francis GroupBasic Principles of Drug Discovery and Development presents the multifaceted process of identifying a new drug in the modern era, providing comprehensive explanations of enabling technologies such as high throughput screening, structure based drug design, molecular modeling, pharmaceutical profiling, and translational medicine, all areas that have become critical steps in the successful development of marketable therapeutics. The text introduces the fundamental principles of drug discovery and development, also discussing important drug targets by class, in vitro screening methods, medicinal chemistry strategies in drug design, principles in pharmacokinetics and pharmacodynamics, animal models of disease states, clinical trial basics, and selected business aspects of the drug discovery process. It is designed to enable new scientists to rapidly understand the key fundamentals of drug discovery, including pharmacokinetics, toxicology, and intellectual property. As an industrial medicinal chemist, Dr. These experiences, as well as his training and expertise as a registered US patent agent, have provided him with the tools and skills necessary to bridge the gap between industrial drug discovery and academic research.
This book presents a review of recent developments in NMR applications in pharmaceutical research. Consideration is given to consolidated and emerging techniques and methods in NMR, many of which are not widely applied but are likely to provide new opportunities for drug design. The first part of the book is dedicated to the description of NMR as a tool for the analysis of chemicals and interaction with targets. Particular emphasis is put on applications with unexploited potential for drug discovery and development. The next seven chapters describe NMR approaches to investigate in vivo models of interest in drug discovery and development, with the attention focused on anatomy, function, metabolism and molecular-cellular aspects. Finally, consideration is given to the application of in vivo NMR to the identification and characterization of biomarkers with the aim of monitoring the outcome of therapeutic intervention in selected human diseases, including the study of drug metabolism and toxicity.
NCBI Bookshelf. Assay Guidance Manual [Internet]. Published May 1, ; Last Update: July 1, Setting up drug discovery and development programs in academic, non-profit and other life science research companies requires careful planning. This chapter contains guidelines to develop therapeutic hypotheses, target and pathway validation, proof of concept criteria and generalized cost analyses at various stages of early drug discovery. Various decision points in developing a New Chemical Entity NCE , description of the exploratory Investigational New Drug IND and orphan drug designation, drug repurposing and drug delivery technologies are also described and geared toward those who intend to develop new drug discovery and development programs.

We give a brief overview of the medicinal chemistry efforts that led to of the discovery of GDC and the original synthetic sequence. From the original medicinal chemistry synthesis, we address key limitations to further increase stereoselectivity and yields and the determination of the active pharmaceutical ingredients API final form to support Phase 1 clinical development. Given the high therapeutic potential and an intensely competitive landscape, early engagement between the medicinal and process chemistry teams contributed to an accelerated development timeline but precluded de novo process development for the first multikilogram delivery. Safety analysis indicated that several intermediates in the original synthesis presented an explosion hazard on scale, requiring a strategic redesign of the chemical synthesis to avoid high-energy intermediates. Key challenges for kilogram production that required development included cryogenic lithiated sulfone addition to a tert—butanesulfinimine, ozonolysis, and conversion of an aryl halide to aniline via an ammonia surrogate. The medicinal chemistry effort that culminated in the invention of verubecestat focused on the design, synthesis, and evaluation of various iminoheterocyclic BACE1 inhibitors in order to discover a compound with a profile that would enable clinical progression to evaluate the safety and efficacy of chronic administration in patients.
