Multivalent Molecules provides basic principles of multivalent interactions found in biological systems as well as an up-to-date and thorough coverage in design concepts, syntheses, and biological activities of multivalent molecules. Multivalent interaction plays an important and unique role in biological systems which is not possible with monovalent interaction. The multivalent concept proves to be an effective chemical strategy in designing molecules which are capable of modulating the functions of diverse macromolecular targets found widely in cell, bacterium, and virus. This book contains practical examples of synthetic multivalent molecules in chemistry, biology, and medicine.
