Nanoparticulate Drug Delivery Systems For Cancer Therapy

In recent years, nanoparticles—bionanomaterials with specific physicochemical properties—have gained a great deal of scientific interest owing to their unique structure. Nanoparticle-based drugs are now widely regarded as a safer, more precise, and more effective mode of cancer therapy, considering their ability to enhance drug bioavailability, improve site-specific drug delivery, and protect nontarget tissues from toxic therapeutic drugs. This book compiles and details cutting-edge research in nanomedicine from an interdisciplinary team of international cancer researchers who are currently revolutionizing drug delivery techniques through the development of nanomedicines and nanotheranostics. Edited by Hala Gali-Muhtasib and Racha Chouaib, two prominent cancer researchers, this book will appeal to anyone involved in nanotechnology, cancer therapy, or drug delivery research.

Molecular medicine has discovered many new therapeutic modalities by using state-of- the-art techniques in molecular biology. High through-put, in-vitro assays that screen for pharmacological actions on the desired cell type are frequently used to design new drugs. Although such agents are certainly justified by their, success in-vitro, they frequently perform much less effectively in-vivo where the agent must reach its target cells in a tissue in sufficient quantities to be potent while sparing bystander organs. Depending on the route of administration, the endothelium and/or epithelium form significant barriers that greatly limit the in-vivo accessibility of many drugs, antibodies, and gene vectors to their intended target sites of pharmacological action, namely, the cells inside the tissue (Jain, R. K. et al., 1998). Hence, the major challenge for formulation development scientist is to design drug delivery strategies that deliver the therapeutic agents to the desired intracellular targets based on ability to understand, utilize, modify and exploit membrane trafficking pathways (Miller, N. et al., 1995). Intracellular drug delivery refers to the delivery of therapeutic agents to specific compartments or organelles within the cell. The therapeutic agent could be a low molecular weight drug or a macromolecule like protein or DNA. Thus targeted intracellular drug delivery results in higher bioavailability of a therapeutic agent at its site of action (i.e. distinct intracellular compartments or microenvironments), potentiates the pharmacologic effect of the drug, and at the same time, reduces the side effects. (Jayanth Panyam et al, 2004). There are a number of pathways through which a therapeutic agent or a carrier can enter a cell. Such as Endocytosis, Caveolar endocytosis, Pinocytosis, Phagocytosis, In receptor-mediated endocytosis, Folate Receptor-Mediated Endocytosis, Transferrin Receptor-Mediated Endocytosis, Biotin Receptor-Mediated Endocytosis, Wheat Germ Agglutinin-Mediated Endocytosis, ICAM-1-Mediated Endocytosis, Antibody-Mediated Endocytosis, Physical or mechanical methods use force to traverse the cell membrane, e.g. Particle bombardment accelerates, Microinjection and Electroporation. The various Intracellular Targets are Endo-Lysosomal Targeting, Cytoplasmic Delivery, Nuclear Targeting, and Mitochondrial Targeting.

Focusing on nanoparticulate nanocarriers and recent advances in the field of drug delivery, the volume begins with chapters that provide an informative introduction to polymeric nanoparticles—their general physicochemical features and characteristics, their applications in drug delivery systems, and the challenges involved. Specific applications are discussed, with attention paid to treatment of particular diseases and disorders and the targeting of specific organs. Part 2 looks at more specific applications and techniques of nanoparticulate nanocarriers for drug delivery, such as the use of magnetic nanoparticles, gold nanoparticles in therapeutics, and superparamagnetic iron oxide nanoparticles (SPIONs) for the treatment of cancer. Part 3 discusses lipid-based nanoparticulates for various applications, including skin care. The last section of the book explores some of the newer nanoarchitectures, including dendrimers in gene delivery and carbon nanotubes for drug delivery. Together, the insightful research presented here provides valuable information for those involved in this area, including scientists and researchers and faculty and upper-level students, as well as for industry professionals.

Advanced Drug Delivery Systems in the Management of Cancer discusses recent developments in nanomedicine and nano-based drug delivery systems used in the treatment of cancers affecting the blood, lungs, brain, and kidneys. The research presented in this book includes international collaborations in the area of novel drug delivery for the treatment of cancer. Cancer therapy remains one of the greatest challenges in modern medicine, as successful treatment requires the elimination of malignant cells that are closely related to normal cells within the body. Advanced drug delivery systems are carriers for a wide range of pharmacotherapies used in many applications, including cancer treatment. The use of such carrier systems in cancer treatment is growing rapidly as they help overcome the limitations associated with conventional drug delivery systems. Some of the conventional limitations that these advanced drug delivery systems help overcome include nonspecific targeting, systemic toxicity, poor oral bioavailability, reduced efficacy, and low therapeutic index. This book begins with a brief introduction to cancer biology. This is followed by an overview of the current landscape in pharmacotherapy for the cancer management. The need for advanced drug delivery systems in oncology and cancer treatment is established, and the systems that can be used for several specific cancers are discussed. Several chapters of the book are devoted to discussing the latest technologies and advances in nanotechnology. These include practical solutions on how to design a more effective nanocarrier for the drugs used in cancer therapeutics. Each chapter is written with the goal of informing readers about the latest advancements in drug delivery system technologies while reinforcing understanding through various detailed tables, figures, and illustrations. Advanced Drug Delivery Systems in the Management of Cancer is a valuable resource for anyone working in the fields of cancer biology and drug delivery, whether in academia, research, or industry. The book will be especially useful for researchers in drug formulation and drug delivery as well as for biological and translational researchers working in the field of cancer.
