Repurposed

​This book presents drug repurposing strategies to combat infectious diseases and cancer. It discusses key experimental and in silico approaches for modern drug repositioning, including signature matching, molecular docking, genome-wide associated studies, and network-based approaches aided by artificial intelligence. Further, the book presents various computational and experimental strategies for better understanding disease mechanisms and identify repurposed drug candidates for personalized pharmacotherapy. It also explores the databases for drug repositioning, summarizes the approaches taken for drug repositioning, and highlights and compares their characteristics and challenges. Towards the end, the book discusses challenges and limitations encountered in computational drug repositioning.

Drug repurposing, or repositioning, is the development of existing drugs for new uses: given that 9 in 10 drugs that enter drug development are never marketed and therefore represent wasted effort, it is an attractive as well as inherently more efficient process. Three repurposed drugs can be brought to market for the same cost as one new chemical entity; and they can also be identified more quickly, an important benefit for patients whose diseases are progressing faster than therapeutic innovation. But repurposing also requires a fresh look at configuring pharmaceutical R&D, considering clinical, regulatory and patent issues much earlier than would otherwise be the case. In addition to new ways of thinking, the discovery of repurposing opportunities can take advantage of artificial intelligence techniques to match the perfect new use for an existing drug. This book provides an ideal introduction to the field of drug repurposing with contributions from world-renowned experts culminating in an excellent resource for any drug discovery or medicinal chemist.

This book focuses on various aspects and applications of drug repurposing, the understanding of which is important for treating diseases. Due to the high costs and time associated with the new drug discovery process, the inclination toward drug repurposing is increasing for common as well as rare diseases. A major focus of this book is understanding the role of drug repurposing to develop drugs for infectious diseases, including antivirals, antibacterial and anticancer drugs, as well as immunotherapeutics.

Drug repurposing, or drug repositioning, or reprofiling, has emerged as a valid approach in modern drug discovery. The book describes tools and techniques for identifying new therapeutic potentials for existing drugs and covers the repurposing of drugs from synthetic and natural origin. It compares the costs of drug repurposing with traditional drug discovery and discusses challenges and future perspectives of drug repurposing.

Drug repurposing is a cost-effective method of discovering new treatments for diseases than traditional drug development methods. It involves virtual screening of chemical candidates with the aid of computational methods like molecular docking. Drug Repurposing against SARS-CoV2 focuses on current trends in drug repurposing against the novel coronavirus strains. The book aims to give readers an overview of drug repurposing against COVID-19 and various techniques involved in the process. The book consolidates available information on the pathophysiology, drug targets, and drug repurposing against COVID-19 into a single, convenient resource. Key features • An up-to-date compilation of the evidence that supports the drug repurposing for COVID-19. • How to use repurposing of available drugs for disease therapy. • Provides an improved understanding of pathophysiology and SARS-CoV2 viral entry pathways. • Provides references for further reading
