Semisynthesis of Bioactive Compounds and their Biological Activities (eBook)

Semisynthesis of Bioactive Compounds and their Biological Activities explores the potential benefits of semisynthetic derivatives obtained from nature. Sections cover the natural distribution of parent compounds, semisynthesis and biological properties of semisynthetic derivatives, the applications of semisynthetic derivatives in diverse fields such as drug delivery, food production and medicine, an explanation of the current resistance mechanisms of antibiotics, clinical applications of semisynthetic analogues, the functions of plant alkaloids on human health, potential agricultural biotechnology in semisynthetic derivatives, and semisynthesis of natural products under greener conditions, this book provides a comprehensive resource on the topics presented. Sections include information about alternative sources of energy and superior greener technologies (microwave, sonochemistry), alternative reaction media (water, supercritical CO2, ionic liquids) and alternative eco-friendly catalysts (biocatalysts). This book will be an excellent resource for academicians, researchers and students focusing on synthesis as well as the biological community and industry professionals in drug development. - Focuses on the current resistance mechanisms of antibiotics, chemical derivatization of antibiotics, and clinical applications of semisynthetic derivatives. - Includes discussion of the semisynthesis of natural products using green tools, green solvents, and eco-friendly catalysts. - Illustrates the concept of toxicity, the merits of transition-metal-free reactions, and the semisynthesis of natural products by introducing the oxygen atom(s) under transition-metal-free conditions.

Sasadhar Majhi received B.Sc. (Honours) degree in Chemistry and M.Sc. (Organic specialization), both from Visva-Bharati (a Central University founded by Rabindranath Tagore, a Nobel laureate). He received M.Phil (Chemistry) in 2009 and obtained a PhD from Visva-Bharati University under the supervision of Prof. Goutam Brahmachari. Currently, he serves as the coordinator of the department of chemistry (UG & PG departments) of Triveni Devi Bhalotia College (Government Sponsored and Affiliated to the Kazi Nazrul University, Asansol, previously affiliated to the Burdwan University), Raniganj, West Bengal, India. He started his professional career as an Assistant Professor of this college and worked as Assistant Lecturer at Patha-Bhavana, Visva-Bharati University (a Central University), Santiniketan, West Bengal. He is a member of IQAC and the Coordinator of the environmental science of TDB College. He teaches undergraduate and postgraduate students of chemistry and also undergraduate students of biochemistry. With over ten years of teaching experience, Dr Majhi has published several research papers in national and international journals of high reputate. Dr Majhi is co-editor of Science and Technology: A Concise History and Evolution. He has also participated in various national and international conferences and symposia. His research interests focus on the isolation and structural determination of natural products, semisynthetic products, total synthesis, green chemistry, as well as biological activities of phytochemicals.
