Book Description
Solids that possess acidic properties on their surfaces function as catalysts just like liquid acids, such as sulfuric acid and hydrochloric acid. By using solid acid catalysts, chemical processes become more productive and more environmentally friendly. In fact, solid acids are being used in many industrial chemical processes from the largest chem

Book Description
Organic Reaction Mechanisms 2013, the 49th annual volume in this highly successful and unique series, surveys research on organic reaction mechanisms described in the available literature dated 2013. The following classes of organic reaction mechanisms are comprehensively reviewed: Reaction of Aldehydes and Ketones and their Derivatives Reactions of Carboxylic, Phosphoric, and Sulfonic Acids and their Derivatives Oxidation and Reduction Carbenes and Nitrenes Nucleophilic Aromatic Substitution Electrophilic Aromatic Substitution Carbocations Nucleophilic Aliphatic Substitution Carbanions and Electrophilic Aliphatic Substitution Elimination Reactions Polar Addition Reactions Cycloaddition Reactions Molecular Rearrangements An experienced team of authors compile these reviews every year, so that the reader can rely on a continuing quality of selection and presentation.

Book Description
The development of agents capable of cleaving RNA and DNA has attracted considerable attention from researchers in the last few years, because of the immediate and very important applications they can find in the emerging fields of biotechnology and pharmacology. There are essentially two classes of these agents - nucleases that occur naturally inside cells and synthetically produced artificial nucleases. The first class includes protein enzyme nucle ases and catalytic RNA structured ribozymes that perform cleavage of the phosphodiester bonds in nucleic acids according to a hydrolytic pathway in the course of different biochemical processes in the cell. A different pathway is used by some antibiotics which cleave DNA via redox-based mechanisms resulting in oxidative damage of nucleotide units and breakage of the DNA backbone. The above molecules are indispensable tools for manipulating nucleic acids and processing RNA; DNA-cleaving antibiotics and cytotoxic ribonucleases have demonstrated utility as chemotherapeutic agents. The second class, artificial nucleases, are rationally designed to imitate the active centers of natural enzymes by simple structures possessing minimal sets of the most important characteristics that are essential for catalysis. A dif ferent approach, in vitro selection, was also used to create artificial RNA and DNA enzymes capable of cleaving RNA. Being less efficient and specific as compared to the natural enzymes, the primitive mimics are smaller and robust and can function in a broad range of conditions.

Book Description
Many drugs and other xenobiotics (e.g., preservatives, insecticides, and plastifiers) contain hydrolyzable moieties such as ester or amide groups. In biological media, such foreign compounds are, therefore, important substrates for hydrolytic reactions catalyzed by hydrolases or proceeding non-enzymatically. Despite their significance, until now, no book has been dedicated to hydrolysis and hydrolases in the metabolism of drugs and other xenobiotics. This work fills a gap in the literature and reviews metabolic reactions of hydrolysis and hydarion from the point of views of enzymes, substrates, and reactions.

Book Description
Part 3 of the Handbook of Experimental Pharmacology (Concepts in Biochem ical Pharmacology) applies the principles enunciated in Parts 1 and 2 to clinical pharmacology and toxicology. The major objective is to elucidate the many factors that determine the relationships between pharmacokinetic aspects of the disposition and metabolism of drugs and their therapeutic or toxic actions in man. Because of the more restricted information obtainable in human studies, this volume reflects the editors' bias that an understanding of pharmacokinetics is fundamental for assessing pharmacologic or toxicologic effects of drugs in humans. The first chapter is a unique primer on when to apply and how to use pharmaco kinetic tools in human pharmacology. The second chapter explains the general assumptions underlying pharmacokinetic approaches both in simple terms for the novice and in mathematical form for the more sophisticated reader. Several chapters on determinants of drug concentration and activity discuss drug absorption, drug latentiation, drugs acting through metabolites, entero hepatic drug circulation, influence of route of drug administration on response, genetic variations in drug disposition and response, age differences in absorption, distribution and excretion of drugs, and pathologic and physiologic factors affecting absorption, distribution and excretion of drugs and drug response. The focus of these chapters is data obtained in human, rather than animal, studies. Most of the chapters contain new material never summarized previously.
