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.

Book Description
The introduction of specific molecules into single cells is a widely used approach to probe cellular mechanisms. For example, to better understand the complex phenomenon of cancer drug resistance due to sequestration, binding and efflux, drug molecules are introduced into cancer cells. To probe cell-cell communication tracer molecules are delivered into connected cells and their junctional permeabilities are estimated. Existing methods for delivering molecules into cells include the injection of discrete boluses of material using mechanical or electro-mechanical principles, and continuous perfusion from a patch pipette in the whole cell configuration. However with these methods delivery cannot be quantified, or can introduce stress to the cells due to volume addition, or can cause excessive washout of cytosolic content. In this work we report on the use of a diffusional microburet that is a micropipette with a diffusion port at its tip to deliver molecules into an impaled target cell, quantifiably and with reduced washout of intracellular constituents. A new ratiometry technique called temporal ratiometry has also been developed in this work to provide dynamic time resolved concentration maps of the delivered molecules within the cell. These methods have been used to determine junctional permeabilities between connected A7r5 cells over a 30 min time frame. The DMB has also been used to dose the anticancer drug doxorubicin into the human breast cancer cell line MCF-7 and the rat epithelial cell line NRKE to titrate intracellular drug binding sites. Doxorubicin was found to accumulate in the nucleus and slow propagation at binding sites at the rate of ~2.0 ± 0.8 micrometers/min (n=4 cells) were observed for the first time. The methods presented in this work can make new types of experiment, such as continuous and quantitative titrations of binding sites, sequestration processes, and efflux pathways on single cells feasible. As an offshoot of diffusive dosing, we also report on the development of a delivery device that uses hydrodynamic resistance in the path of flow to effect very slow deliveries in the order of nL/s to make ultra low concentration solutions in a single step.

Book Description
This book explains how peptide-based drug design works, what steps are needed to develop a peptide-based therapeutic, and challenges in synthesis as well as regulatory issues. It covers the design concept of peptide therapeutics from fundamental principles using structural biology and computational approaches. The chapters are arranged in a linear fashion. A fresh graduate or a scientist who works on small molecules can use this to follow the design and development of peptide therapeutics to use as understanding the basic concepts. Each chapter is written by experts from academia as well as industry. Rather than covering extensive literature, the book provides concepts of design, synthesis, delivery, as well as regulatory affairs and manufacturing of peptides in a systematic way with examples in each case. The book can be used as a reference for a pharmaceutical or biomedical scientist or graduate student who wants to pursue their career in peptide therapeutics. Some chapters will be written as a combination of basic principles and protocol so that scientists can adopt these methods to their research work. The examples provided can be used to perform peptide formulation considerations for the designed peptides. The book has nine chapters, and each chapter can be read as an independent unit on a particular concept.

Book Description
ORAL BIOAVAILABILITY AND DRUG DELIVERY Improve the performance and viability of newly-developed and approved drugs with this crucial guide Bioavailability is the parameter which measures the rate and extent to which a drug reaches a user’s circulatory system depending on the method of administration. For example, intravenous administration produces a bioavailability of 100%, since the drugs are injected directly into the circulatory system; in the case of oral administration, however, bioavailability can vary widely based on factors which, if not properly understood, can result in a failure in drug development, adverse effects, and other complications. The mechanics of oral bioavailability are therefore critical aspects of drug development. Oral Bioavailability and Drug Delivery provides a comprehensive coverage of this subject as well as its drug development applications. Beginning with basic terminology and fundamental concepts, it provides a thorough understanding of the challenges and barriers to oral bioavailability as well as the possibilities for improving this parameter. The resulting book is an indispensable tool for drug development research. Oral Bioavailability and Drug Delivery readers will also find: Discussion questions in many chapters to facilitate comprehension Detailed discussion of topics including dissolution, absorption, metabolism, and more Real-world examples of methods in actions throughout Oral Bioavailability and Drug Delivery is ideal for pharmaceutical and biotechnology scientists working in drug discovery and development; researchers in chemistry, biology, pharmacology, immunology, neuroscience, and other related fields; and graduate courses in drug development and delivery.
