Quantitative Analysis of Cellular Drug Transport, Disposition, and Delivery


Book Description

This thorough book explores some of the most important methods and concepts affecting the quantitative analysis of the transport, targeting, and disposition of chemicals within cells, which in turn impact the macroscopic pharmacokinetics of chemical agents in the whole organism. The first half of the volume focuses on small organic molecules with drug-like characteristics, while the second half delves into the cellular pharmacokinetics of biologics and other macromolecules, including peptide therapeutics, cyclotides, antibodies, as well as nanoparticles, thus creating a comprehensive treatise that approaches cellular pharmacokinetics from the different perspectives of pharmaceutical scientists, chemical biologists, medicinal chemists, and protein engineers dealing with very different chemical agents spanning a wide range of sizes, physicochemical properties, and targeting mechanisms. Written for the Methods in Pharmacology and Toxicology series, chapters provide the kind of key detail and expert implementation advice that leads to excellent results in the lab. Synthetic biologists, biophysicists, and bioengineers are amongst the long list of scientists who could benefit from reading this book or from using it as a textbook. Authoritative and practical, Quantitative Analysis of Cellular Drug Transport, Disposition, and Delivery builds on a long history of drug development and the adding of quantitative methods at the cellular scale in order to inspire new approaches to drug development that are better able to take advantage of phenomena such as soluble-to-insoluble phase transitions or bispecific targeting, which could ultimately be exploited for the development of more effective drug delivery systems and therapeutic agents.




Organelle-Specific Pharmaceutical Nanotechnology


Book Description

This book introduces and discusses the latest in biomedical research--Pharmaceutical Nanotechnology applied at the sub-cellular level.




Intracellular Delivery


Book Description

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.

Cancer Drug Delivery Systems Based on the Tumor Microenvironment


Book Description

This book proposes the importance of new systems of drug design and delivery based on cancer pathophysiology in addition to cancer molecular and cellular biology. The current studies based on molecular and cellular biology while ignoring pathophysiology and pharmacology may be leading the development of antitumor drugs in the wrong direction and wasting a lot of money. Although there have been numerous reports of genetic and phenotypic changes in tumors, a large body of pathological and clinical evidence supports the conclusion that there are no pivotal changes in tumor cells that distinguish them consistently and reliably from normal dividing cells. Unlike using antibiotics against bacterial infection, therefore, anticancer agents (ACAs) need to be delivered selectively to tumor tissues and should be kept there long enough to reproduce the concentrations they reach in the Petri dish, which is a closed space where the cytocidal effects of any anticancer agents (ACAs) including molecular targeting agents are very strong. In the body, however, administered ACAs are cleared with the passage of time. Furthermore, most human cancers possess abundant stroma that hinders the penetration of drugs into the tumor microenvironment. Therefore, to overcome these difficulties, novel drug delivery systems have been designed, such as nanoparticles and ACA conjugated antibodies to stromal components and to cancer cell surface antigens. These advances are described in this book after the first section, which describes core features of the pathophysiology of the cancer microenvironment, on which these new developments are based.

From their direct and recent experience, the readers can achieve a wide vision on the new and ongoing potentialities of different smart drug delivery systems. Since the advent of analytical techniques and capabilities to measure particle sizes in nanometer ranges, there has been tremendous interest in the use of nanoparticles for more efficient methods of drug delivery. On the other hand, this reference discusses advances in the design, optimization, and adaptation of gene delivery systems for the treatment of cancer, cardiovascular, diabetic, genetic, and infectious diseases, and considers assessment and review procedures involved in the development of gene-based pharmaceuticals.




Targeted Intracellular Drug Delivery by Receptor Mediated Endocytosis


Book Description

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.
