Providing the guidance needed for formulation, handling, and quality control of photolabile drugs, Photostability of Drugs and Drug Formulations, Second Edition explores the significance of new information on drug photoreactivity in a pharmaceutical context. Completely revised and updated, with chapter authors drawn from an international panel of experts, the book supplies the background necessary for planning standardized photochemical stability studies as a part of drug development and formulation work. It contains comprehensive coverage of the physical and chemical aspects of drug photoreactivity, formulation, stability testing, and drug design/discovery in one resource.

The contents have been reorganized to focus on the standardization of photostability testing of drug substances and products, in vitro photoreactivity screening of drugs, and various aspects of the formulation of photoreactive substances. The information on in vitro screening of drug photoreactivity is of great relevance for scientists who are developing and validating a set of testing protocols to address photosafety. Discussing kinetic and chemical aspects of drug photodecomposition as well as the practical problems frequently encountered in photochemical stability testing, this book helps you design a test protocol and interpret the results.

Pharmaceutical preformulation and formulation, Mark Gibson, 2nd, ingles

mega[PUNTO]co[PUNTO]nz/#!ZIdX3JBI!TzWkHb77rim9t4Kaw8U-T5_BcSee-5fieGobsE6pz3A

Written by a panel of experts, this book covers every stage of drug development, from candidate drug selection to commercial formulation. It provides practical reference and pragmatic guide on what studies need to be undertaken, for what reasons, and at what key stages of the drug development process. Going beyond coverage of preformulation, the book discusses biopharmaceuticals, drug delivery, formulation, and process development aspects of product development. The contributing authors share their experience and expertise in significant chapters divided into three useful sections: Aiding Candidate Drug Selection, Early Drug Development, and From Product Design to Commercial Dosage Form.

Heterocyclic compounds play a vital role in the metabolism of living cells. Their practical applications range from extensive clinical use to fields as diverse as agriculture, photography, biocide formulation and polymer science. 

Written by leading scholars and industry experts, the Handbook of Heterocyclic Chemistry is thoroughly updated with over 50% new content. It has been rewritten with a new expanded author team, who have carefully distilled essential information on the reactivity, structure and synthesis of heterocycles from the 2008 major reference work Comprehensive Heterocyclic Chemistry III. To bring the work up to date the author team have also added new synthetic examples and structures, key applications and new references from 2008-2010. 

Contains more than 1500 clearly drawn structures and reactions. The highly systematic coverage given to the subject makes this one of the most authoritative single-volume accounts of modern heterocyclic chemistry available and should be useful reference for those teaching a heterocyclic course.

Organic synthesis, the disconnection approach, Warren, 2nd, ingles

mega[PUNTO]co[PUNTO]nz/#!8cFWzaAB!8QtLL9kN0Us8GCfK5Mh8XEZoRy6288OPuvR5nwAfWkY

One approach to organic synthesis is retrosynthetic analysis. With this approach a chemist will start with the structure of their target molecule and progressively cut bonds to create simpler molecules. Reversing this process gives a synthetic route to the target molecule from simpler starting materials. This “disconnection” approach to synthesis is now a fundamental part of every organic synthesis course. 

Organic Synthesis: The Disconnection Approach, 2^nd Edition introduces this important technique, to help students to design their own organic syntheses. There are forty chapters: those on the synthesis of given types of molecules alternate with strategy chapters in which the methods just learnt are placed in a wider context. The synthesis chapters cover many ways of making each type of molecule starting with simple aromatic and aliphatic compounds with one functional group and progressing to molecules with many functional groups. The strategy chapters cover questions of selectivity, protection, stereochemistry, and develop more advanced thinking via reagents specifically designed for difficult problems.

Examples are drawn from pharmaceuticals, agrochemicals, natural products, pheromones, perfumery and flavouring compounds, dyestuffs, monomers, and intermediates used in more advanced synthetic work. Reasons for wishing to synthesise each compound are given.

This second edition has been fully revised and updated with a modern look. Recent examples and techniques are included and illustrated additional material has been added to take the student to the level required by the sequel, “Organic Synthesis: Strategy and Control”.
