This book provides a complete overview of cucurbituril chemistry, covering fundamental aspects including history, synthesis and host-guest chemistry.

Cucurbiturils (CBs) are a young family of molecular containers, able to form stable complexes with various guests, including drug molecules, amino acids and peptides, saccharides, dyes, hydrocarbons, perfluorinated hydrocarbons, and proteins. Since the discovery of the first CB, the field has seen tremendous growth with respect to the synthesis of new homologues and derivatives, the discovery of record binding affinities of guest molecules in their hydrophobic cavity, and associated applications ranging from sensing to drug delivery. Cucurbiturils and Related Macrocycles provides a complete overview of CB chemistry, covering the fundamental aspects including its history, synthesis, host–guest chemistry and the thermodynamic basis thereof. The book will tackle specialist topics such as redox chemistry of CB complexes and CBs in the gas phase, and will address the recent trends of the application of CBs in other fields including biology and materials. Edited by a pioneer of cucurbituril chemistry, and with contributions from global experts, this title will appeal to students and researchers working in supramolecular chemistry, materials chemistry, nanotechnology, organic chemistry, biochemistry and chemical biology.

Advances in Prodrugs: Design and Therapeutic Applications provides a versatile tool in prodrug design and development as well as a concrete perspective on clinical and preclinical studies currently available on prodrugs. The first part of this book discusses different chemical classes of prodrugs, with particular emphasis on metabolic pathways and mechanisms involved in the activation of their functional groups. The second part of the book covers therapeutic applications of prodrugs against the most discussed diseases, providing detailed discussion on recent achievements in the field. This book offers researchers involved in drug discovery key criteria for the successful development of prodrug-based therapeutic tools.Prodrugs are inactive drug precursors which undergo different chemical transformation by metabolic processes to provide pharmacologically active compounds. Prodrugs include a broad range of structurally diverse molecules employed for the treatment of several diseases. - Highlights chemistry and pharmacology-related aspects, offering a versatile tool for readers involved in prodrug development and study - Discusses in-depth treatment of several activation mechanisms and applications for disease treatments - Covers a range of topics from basic contents, design, and mechanisms of actions to current applications in drugs

The chemistry that occurs within confined spaces is the product of a collection of forces, often beyond the molecule, and is not easily ascribed to singular factors. There is a breadth of material types that can define a confined space (e.g. macrocycles, interlocked molecules, porous and non-porous crystals, organic and inorganic/coordination cages) which are rarely discussed together. Studies of supramolecular entities in the solution and solid states are also not often compared in the same discussion, even though the concepts are often similar or can be easily transferred between the two. Chapters in this book combine classical host-guest chemistry with catalysis, reactivity, and modern supramolecular chemistry. They cover the many different technologies used to describe and understand reactivity in confined spaces in one accessible title. With contributions from leading experts, Reactivity in Confined Spaces will be relevant for graduate students and researchers working in supramolecular chemistry, both organic- and inorganic-based, homogeneous and heterogeneous catalysis, polymer chemistry, and materials science in general.

This book explores the role of nanotechnology in the delivery of natural phytoconstituents and cosmeceuticals. It presents polymeric nanocarriers, lipid-based nanocarriers, metal/metal oxide nanocarriers, protein nanocarriers, and dendrimers for the delivery of phytoconstituents. Further, it focuses on the usage of phytocompounds in various cosmeceutical products and nano delivery technologies used in the delivery of various cosmeceuticals. Finally, the book reviews the toxicity issues of nanoparticles in the delivery of phytoconstituents and cosmeceuticals and regulatory aspects for clinical applications of nano phytomedicines. This book is helpful for academicians and researchers working in pharmaceutical sciences, nano science, material science, plant science, and cosmetic science.

Assembly, Architecture and Application

Fluorescent chemosensors have been widely applied in many diverse fields such as biology, physiology, pharmacology, and environmental sciences. The interdisciplinary nature of chemosensor research has continued to grow over the last 25 years to meet the increasing needs of monitoring our environment and health. More recently, a large range of fluorescent chemosensors have been established for the detection of biologically and/or environmentally important species, and are increasingly being used to solve biological problems. The use of these molecules as imaging probes to diagnose and treat disease is gaining momentum with clear future applications. This book will bring together world-leading experts to describe the current state of play in the field and introduce the cutting-edge research and possible future directions into fluorescent chemosensors design. Chapters focus on the basic principles involved in the design of chemosensors for specific analytes, problems, and challenges in the field. Concentrating on advanced techniques and methods, the book will be of use for academics and researchers across a number of disciplines, with international appeal.
