Benzimidazole: Preparation and Applications first defines the structure, physical and chemical properties of the benzimidazole compound class. Further conventional and alternative synthesis methods and important reactions of these compound derivatives are illustrated with examples. The authors provide an overview of benzimidazole-based synthetic medicine and their significant applications in treating various ailments. The chemical reactions of benzimidazole with other heterocyclic compounds/chemical reagents produce a lot of new substituted molecules, which have potential pharmaceutical applications. A literature review is presented focusing on the synthesis of chiral compounds and their subsequent applications as therapeutic compounds in order to better evaluate the results so far. Additionally, the authors discuss how nenzimidazole derivatives play a vital role in organic light emitting diodes as emissive materials, host materials, electron transport materials, hole blocking materials, etc., and have pharmaceutical applications such as antimicrobial, antihypertensive, anti-HIV and anticancer. Following this, this collection examines classes of potential chemosensors possessing benzimidazole moieties which are capable of both visual and optical estimation of target analytes over a broad concentration range and without interference of contemporary analytes. Important methodologies used for the synthesis of variedly substituted benzimidazoles are presented along with their multi-target therapeutic uses. The latest research on anti-tumor and antimicrobial benzimidazole compounds, as well as structure-activity correlations, drug design, clinical and preclinical studies is also presented. Benzimidazole-based polymers with various architecture and copolymers are discussed with a variation of properties such as mechanical, thermal stability, thermo-oxidative stability and enhanced performance. The penultimate chapter covers a critical analysis of the recent developments in benzimidazole framework research and the future scope of benzimidazole framework in ligand designing. In closing, the synthesis and biological properties of coordination compounds containing benzimidazole derivatives are presented and discussed.

This book reviews the fundamental aspects of quinoxaline chemistry: synthesis, reactions, mechanisms, structure, properties, and uses. The first four chapters present a survey of the developments in quinoxaline chemistry since the publication of the monograph on “Condensed Pyrazines” by Cheeseman and Cookson in 1979. These chapters give comprehensive coverage of all the methods of the synthesis of quinoxalines and the important quinoxaline-containing ring systems such as thiazolo[3,4-a]-, pyrrolo[1,2-a]-, and imidazo[1,5-a]quinoxalines. Chapter five describes many new methods for the construction of quinoxaline macrocycles, which are important in applications such as optical devices and materials. The final chapter reviews all previously known rearrangements of heterocyclic systems that lead to benzimidazole derivatives. Mamedov critically analyses these transformations to reveal a novel acid-catalyzed rearrangement of quinoxalinones giving 2-heteroarylbenzimidazoles and 1-heteroarylbenzimidazolones in the presence of nucleophilic reactants (MAMEDOV Heterocycle Rearrangement). This book is of interest to researchers in the fields of heterocyclic and synthetic organic chemistry.

Extensive experimentation and high failure rates are a well-recognised downside to the drug discovery process, with the resultant high levels of inefficiency and waste producing a negative environmental impact. Sustainable and Green Approaches in Medicinal Chemistry reveals how medicinal and green chemistry can work together to directly address this issue. After providing essential context to the growth of green chemistry in relation to drug discovery in Part 1, the book goes on to identify a broad range of practical methods and synthesis techniques in Part 2. Part 3 reveals how medicinal chemistry techniques can be used to improve efficiency, mitigate failure and increase the environmental benignity of the entire drug discovery process, whilst Parts 4 and 5 discuss natural products and microwave-induced chemistry. Finally, the role of computers in drug discovery is explored in Part 6. - Identifies novel and cost effective green medicinal chemistry approaches for improved efficiency and sustainability - Reflects on techniques for a broad range of compounds and materials - Highlights sustainable and green chemistry pathways for molecular synthesis

Until quite recently conditions in industry were often rough. Long hours were worked in insanitary and murky workshops, often with little regard to the effects upon the workpeople who were considered to be expendable. Now, however, these adverse conditions have been recognized and so remedied that there remains little in industrial conditions to disturb the public conscience. This does not mean that conditions of work in office or factory are perfect. The obvious and dramatic abuses of the human frame may have gone, but in their place have arisen stresses and strains which, taking effect only in the long term, are generally undramatic and often unrecognized. They exist none the less. No organized effort to study the effect of working conditions on man's performance was made until the end of World War I, when the Industrial Fatigue Research Board was set up. For the first time, men trained in the human sciences entered industry to study men at work. They made con tributions which set a new standard of scientific investigation into human performance and allowed executive action on the basis of evidence rather than of hunch. The Board's work differed from the contribution of Gilbreth in America in that the principles of Motion Study which he developed were, to a large extent, based on intelligent observation rather than controlled experiment. During the 1920S the National Institute of Industrial Psychology was founded and there was close collaboration between it and the I.F.R.B.
