Download or read book Bioactive Heterocyclic Compound Classes written by Clemens Lamberth and published by John Wiley & Sons. This book was released on 2012-08-14 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of heterocycles is an important branch of organic chemistry. This is due to the fact that a large number of natural products, e. g. hormones, antibiotics, vitamins, etc. are composed of heterocyclic structures. Often, these compounds show beneficial properties and are therefore applied as pharmaceuticals to treat diseases or as insecticides, herbicides or fungicides in crop protection. This volume presents important agrochemicals. Each of the 21 chapters covers in a concise manner one class of heterocycles, clearly structured as follows: * Structural formulas of most important examples (market products) *Short background of history or discovery * Typical syntheses of important examples * Mode of action * Characteristic biological activity * Structure-activity relationship * Additional chemistry information (e.g. further transformations, alternative syntheses, metabolic pathways, etc.) * References A valuable one-stop reference source for researchers in academia and industry as well as for graduate students with career aspirations in the agrochemical chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: This timely book provides a succinct summary of methods for the synthesis of bioactive heterocycles using a multicomponent reaction (MCR) approach. The majority of pharmaceuticals and biologically active agrochemicals are heterocycles while countless additives and modifiers used in industrial applications are heterocyclic in nature. With the recent introduction of high-throughput biological evaluation, the importance of MCRs for drug discovery has been recognized and considerable efforts have been focused especially on the design and development of multi-component procedures for the generation of various bioactive heterocycles due to their significant therapeutic potential.

Download or read book Non Conventional Synthesis written by György Keglevich and published by Walter de Gruyter GmbH & Co KG. This book was released on 2023-11-06 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-conventional synthetic methods may provide new and green methods for the preparation of bioactive heterocycles. These methods, such as microwave and ultrasound assisted synthesis, biocatalysis, photochemistry and electrosynthesis use less energy and may produce less waste to get the desired products when compared to traditional methods. This book explores the use of these methods when synthesizing various biologically relevant heterocyclic scaffolds. THE SERIES: GREEN BIOACTIVE HETEROCYCLES Heterocycles are a widely utilized group of molecules as they often contain bioactivity that is useful in drug development, agriculture, and other applications. However, their synthesis remains challenging with diffi cult to control functional groups. With a greater focus on sustainable synthesis practices, there is a need to develop greener synthetic methods for the synthesis of structurally diverse bioactive heterocyclic scaffolds. This series aims to do so, by collecting developments into common themes.

Download or read book Targeting Bioactive Heterocycles written by Victoria Alison McKay and published by . This book was released on 2015 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family of structurally unrivalled fungal metabolites, the zaragozic acids (ZAs), have been a favoured synthetic challenge of organic chemists for over 20 years. ZAs uniquely contain a highly oxygenated 4,6,7 trihydroxy 2,8 dioxabicyclo [3.2.1] octane-3,4,5-tri-carboxylic acid core; a construct including six contiguous stereocentres, four of which are quaternary sites. Chapters 1 and 2 describe the discovery and biological significance of the ZAs - extensively covering recent works published toward their synthesis - concluding with our intended synthetic approach toward development of the ZA core. Chapter 3 encompasses research and conclusions concerning the synthesis of pinacol reaction substrates and their transition-metal-mediated coupling - including the elucidation of a number of novel heterocycles during these processes. Chapter 4 describes the optimisation and scope of a new, concise protocol deriving 5-disubstituted imidazoldine-2,4-diones from [alpha] ketoacids and carbodiimides, and applies the new method to the construction of an analogue of the marine metabolite, Polyandrocarpamide D.Chapter 5 communicates our synthetic work toward the development of pro-fluorescent derivatives of fluorescent isomorphic nucleosides. The maximal homology of isomorphic nucleosides ensures that these non-native nucleosides are well tolerated upon incorporation into DNA or RNA, with only minimal impact on sequence folding, while still allowing discrete localisation, and expedient sensitivity and responsiveness to microenvironments. Chapter 5 includes description of our investigations toward a robust synthetic methodology for the production of "pro-fluorescent" C 5/C 6-reduced, uridine/thymidine nucleobase analogues. These analogues possess the potential to report on oxidative microenvironments; whereby exposure to oxidative conditions in vivo or in vitro results in conversion to their fluorescent counterparts, consequently expressing analysable photophysical characteristics. Our synthetic approach to the desired C-5/C-6-reduced base motif utilises a pathway developed by the Perlmutter group, using [3+3]-sigmatropic rearrangement of an acyl hydroxamic acid, followed by intramolecular trapping of the substrate during a Curtius reaction, to obtain the profluorescent nucleobase analogue.
