Book excerpt: The lipid bilayer's integrity is essential for cell function as it acts as the primary barrier against external molecules like drugs and peptides, which can alter the bilayer's physical properties. This dissertation investigates how amphetamine (AMPH) and methamphetamine (METH), and the charged HIV1-TAT peptide impact the stability of lipid bilayers, using a home-built lipid bilayer apparatus that enables real-time monitoring through electrical and fluorescence measurements. Our findings indicate that AMPH and METH increase the lipid bilayer's ion permeability, with METH having a greater destabilizing effect. High concentrations of these stimulants, akin to levels in blood plasma of individuals with stimulant-related brain injuries, lead to pore formation in the bilayer. The extent of destabilization correlated with the drug concentration. We also studied the translocation dynamics of the charged HIV1-TAT peptide across the lipid bilayer. The analysis of current fluctuations showed that successful translocation of the TAT peptide is concentration-dependent, highlighting the significance of charge in inducing membrane deformation or pore formation. Additionally, molecular dynamic simulations were used to explore AMPH interactions with the lipid bilayer in greater detail. The results revealed AMPH's preferred orientation during interaction and its hydrophobic nature, as evidenced by the larger energy barrier encountered in the hydrophilic head group regions of the lipid bilayer. To complement these findings, we utilized surface-enhanced Raman spectroscopy (SERS) to estimate the concentrations of AMPH within lipid bilayers. The data showed a positive correlation between characteristic peak heights and AMPH concentrations. Moreover, whole-cell patch clamp measurements on neuronal cells were employed to examine AMPH's effects in a more intricate lipid environment. This research contributes to the understanding of how stimulants and charged peptides interact with lipid bilayers, which is vital for insights into their biological impacts and in developing therapeutic interventions.

Available in PDF, EPUB and Kindle. Book excerpt: Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular modeling techniques have been widely used in drug discovery fields for rational drug design and compound screening. Now these techniques are used to model or mimic the behavior of molecules, and help us study formulation at the molecular level. Computational pharmaceutics enables us to understand the mechanism of drug delivery, and to develop new drug delivery systems. The book discusses the modeling of different drug delivery systems, including cyclodextrins, solid dispersions, polymorphism prediction, dendrimer-based delivery systems, surfactant-based micelle, polymeric drug delivery systems, liposome, protein/peptide formulations, non-viral gene delivery systems, drug-protein binding, silica nanoparticles, carbon nanotube-based drug delivery systems, diamond nanoparticles and layered double hydroxides (LDHs) drug delivery systems. Although there are a number of existing books about rational drug design with molecular modeling techniques, these techniques still look mysterious and daunting for pharmaceutical scientists. This book fills the gap between pharmaceutics and molecular modeling, and presents a systematic and overall introduction to computational pharmaceutics. It covers all introductory, advanced and specialist levels. It provides a totally different perspective to pharmaceutical scientists, and will greatly facilitate the development of pharmaceutics. It also helps computational chemists to look for the important questions in the drug delivery field. This book is included in the Advances in Pharmaceutical Technology book series.

Available in PDF, EPUB and Kindle. Book excerpt: New textbooks at all levels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction mechanisms, and chemical thermody namics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the graduate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research which is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases, the availability of texts in active research areas should help stimulate the creation of new courses.

Available in PDF, EPUB and Kindle. Book excerpt: It is common practice to publish conference papers in books or monograph series. This gives some advantage to those who did not have the opportunity to attend the meetings, but it irritates and disappoints others who may have hoped for a set of closely related reviews. With this book we have tried to find a compromise. It presents a selection from the topics which have been discussed in a series of inter national symposia entitled "Biophysics of Cell Surface", held in 1976, 1978, 1981, 1985 and 1988 in the GDR, and subsequently published in the journal STUDIA BIOPHYSICA (volumes 56, 74, 90, 110, 1271. Nearly all the contributors to this book participated in one or more of the meetings. We hope that our choice of topics selected for this book manages to reflect the variety and interest of the broad range of subjects which fall within the scope of membrane biophysics, without taking on the randomness of a scientific car-boot sale. We would like to express our thanks to all colleagues and organ~ isations who helped to realize the conferences and particularly this book. financial support for the symposia of 1985 and 1988 was provided by the IUPAB. A number of topics, reflected in this book, resulted in internat ional cooperations, supported by various organisations. We are especially grateful for the support of UNESCO research project on biophysicS in this respect. The European Bureau (ROSTE) of UNESCO supported the editorial work of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Proteins are indispensable players in virtually all biological events. The functions of proteins are coordinated through intricate regulatory networks of transient protein-protein interactions (PPIs). To predict and/or study PPIs, a wide variety of techniques have been developed over the last several decades. Many in vitro and in vivo assays have been implemented to explore the mechanism of these ubiquitous interactions. However, despite significant advances in these experimental approaches, many limitations exist such as false-positives/false-negatives, difficulty in obtaining crystal structures of proteins, challenges in the detection of transient PPI, among others. To overcome these limitations, many computational approaches have been developed which are becoming increasingly widely used to facilitate the investigation of PPIs. This book has gathered an ensemble of experts in the field, in 22 chapters, which have been broadly categorized into Computational Approaches, Experimental Approaches, and Others.
