This book was released on 2019-11-09 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book elaborates on drug delivery targeting via intracellular delivery, specifically through the Receptor Mediated Endocytosis (RME) approach, due to the involvement of cellular receptors in various grave diseases. Targeted delivery relies on two basic approaches, passive and active targeting. While passive targeting approaches have shown great promise, the improved selectivity achieved with active targeting approaches has resulted in significantly higher efficacy. Interestingly there are numerous strategies for active targeting, many of which are already highlighted in , Targeted Drug Delivery: Concepts and Applications. Nevertheless an exciting and practical strategy for active targeting, which could enable high intracellular delivery, is through exploitation of RME. Cells in the body express receptors to enable various physiological and biochemical processes. As a result, many of these receptors are overexpressed in pathological conditions, or newer receptors expressed due to defective cellular functioning. RME is based on exploitation of such receptors to achieve intracellular delivery. While targeted delivery can have manifold applications, in this book we focus on two major and challenging therapeutic areas; i) Cancer and ii) Infectious Diseases. Targeted Intracellular Drug Delivery by Receptor Medicated Endocytosis discusses the major receptors that are useful for targeted delivery for these afflictions. A major section of this book is dedicated to details regarding their occurrence and location, the recognition domain of the receptor, structure activity relationship of substrate /ligand for selective binding, ligands explored, antagonists for ligand binding and relevance of these aspects for therapy of cancer and infectious diseases. These facets are elucidated with the help of specific examples from academic research and also emphasize commercial products, wherever relevant. In vitro cellular models relied on for assessing receptor mediated cellular targeting and in vivo models depicting clinical efficacy are focused on in a separate section. Finally, we briefly discuss the regulatory and toxicity issues that may be associated specifically with the RME approach of intracellular drug delivery.

This book was released on 2023-03-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Intracellular Delivery written by Aleš Prokop and published by Springer Science & Business Media. This book was released on 2011-05-26 with total page 871 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book features a special subsection of Nanomedicine, an application of nanotechnology to achieve breakthroughs in healthcare. It exploits the improved and often novel physical, chemical and biological properties of materials only existent at the nanometer scale. As a consequence of small scale, nanosystems in most cases are efficiently uptaken by cells and appear to act at the intracellular level. Nanotechnology has the potential to improve diagnosis, treatment and follow-up of diseases, and includes targeted drug delivery and regenerative medicine; it creates new tools and methods that impact significantly upon existing conservative practices. This volume is a collection of authoritative reviews. In the introductory section we define the field (intracellular delivery). Then, the fundamental routes of nanodelivery devices, cellular uptake, types of delivery devices, particularly in terms of localized cellular delivery, both for small drug molecules, macromolecular drugs and genes; at the academic and applied levels, are covered. The following section is dedicated to enhancing delivery via special targeting motifs followed by the introduction of different types of intracellular nanodelivery devices (e.g. a brief description of their chemistry) and ways of producing these different devices. Finally, we put special emphasis on particular disease states and on other biomedical applications, whilst diagnostic and sensing issues are also included. Intracellular delivery / therapy is a highly topical which will stir great interest. Intracellular delivery enables much more efficient drug delivery since the impact (on different organelles and sites) is intracellular as the drug is not supplied externally within the blood stream. There is great potential for targeted delivery with improved localized delivery and efficacy.
Download or read book Receptor Mediated Targeting of Drugs written by Gregory Gregoriadis and published by Springer. This book was released on 1984 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional attempts to control cell behaviour and function are often marred by the toxicity of the drugs used, their premature waste or inactivation or by their inability to interact with or reach target sites efficiently. New trends in pharmacology empha size the development of methods for the optimization of drug action, for instance by the delivery of drugs, enzymes, hormones, antigens, genetic material, ets. through carrier systems selectively to re levant cellular and subcellular sites. A wide assortment of carriers was discussed in the first NATO Advanced Studies Institute (ASI) "Targeting of Drugs," the proceedings of which were published by Plenum Press in 1982 (eds., G. Gregoriadis, J. Senior and A. Trouet). This book, containing the proceedings of the 2nd NATO ASI "Receptor-Mediated Targeting of Drugs" held again at Cape Sounion, Greece during 20 June-l July 1983, deals with drug delivery through systems possessing ligands which can recognize and interact with receptors on the target's surface. Receptor-recognizing carriers that have recently given promise of realistic expectations in targeting include monoclonal antibodies, certain proteins that home to specific cells in the body and liposomes either as such (when they can trigger specific reactions in the reticuloendothelial system) or in association with targeting macromolecules. Each of these are discussed extensively by leading authorities, in terms of applications in biology and medicine and related methodologies.
