Book Synopsis Synthesis of Optically Active Alpha-Amino Acids by : R. M. Williams
Download or read book Synthesis of Optically Active Alpha-Amino Acids written by R. M. Williams and published by Elsevier. This book was released on 2013-10-22 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to review and critically evaluate the best new methods to synthesize alpha-amino acids in optically active form. There is so much new literature on amino acid synthesis that the experimentalist will undoubtedly have difficulty in selecting the most appropriate methodology for constructing the amino acid of immediate interest. This book is a guide for steering the scientist through the maze of existing reports on the subject and contains the most up-to-date critical reviews of methods of asymmetric synthesis of amino acids. In areas that are relatively new conceptually and less studied experimentally, an effort has been made to review the most salient works with an eye towards future development. Over 330 schemes and figures are presented with references for rapid visual retrieval of information. The book will be of great value to academic and industrial organic research chemists, especially those concerned with medicinal and agricultural chemistry, as well as to graduate and post graduate students, biochemists and biologists.
Book Synopsis Antimicrobial Peptides by : Katsumi Matsuzaki
Download or read book Antimicrobial Peptides written by Katsumi Matsuzaki and published by Springer. This book was released on 2019-04-12 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of antimicrobial peptides (AMPs), their mechanisms of antimicrobial action, other activities, and various problems that must still be overcome regarding their clinical application. Divided into four major parts, the book begins with a general overview of AMPs (Part I), and subsequently discusses the various mechanisms of antimicrobial action and methods for researching them (Part 2). It then addresses a range of activities other than antimicrobial action, such as cell penetration, antisepsis, anticancer, and immunomodulatory activities (Part 3), and explores the prospects of clinical application from various standpoints such as the selective toxicity, design, and discovery of AMPs (Part 4). A huge number of AMPs have been discovered in plants, insects, and vertebrates including humans, and constitute host defense systems against invading pathogenic microorganisms. Consequently, many attempts have been made to utilize AMPs as antibiotics. AMPs could help to solve the urgent problem of drug-resistant bacteria, and are also promising with regard to sepsis and cancer therapy. Gathering a wealth of information, this book will be a bible for all those seeking to develop antibiotics, anti-sepsis, or anticancer agents based on AMPs.
Book Synopsis Total Synthesis of Natural Products with Antimicrobial Activity by : Andrew Giltrap
Download or read book Total Synthesis of Natural Products with Antimicrobial Activity written by Andrew Giltrap and published by Springer. This book was released on 2018-05-02 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the development of efficient and scalable total syntheses of natural products that can be used as preferred scaffolds for anti-infective drug discovery. It describes the total synthesis of two classes of antimicrobial non-ribosomal peptides (NRPs) – teixobactin and the skyllamycins – with subsequent biological evaluation. The first part describes the first total synthesis of teixobactin by means of a solid-phase peptide synthesis-macrolactamisation approach, yielding a synthetic natural product that can combat a number of clinically relevant Gram-positive bacterial pathogens. The second part describes the first total synthesis of skyllamycins A-C, a family of structurally complex cyclic NRPs, which inhibit the growth of the Pseudomonas aeruginosa biofilms that are responsible for significant mortality among cystic fibrosis patients.

This book was released on 2011-10-17 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2004 in the subject Chemistry - Organic Chemistry, Bangalore University / Central College (Department of Studies in Chemistry), language: English, abstract: The importance of ß-amino acids has been focused, particularly in the past few decades. They are found as components of many biologically active peptidic and nonpeptidic natural products with antibiotic, antifungal, cytotoxic, and other pharmacological properties. ß-Amino acids are produced in humans, animals, microorganisms, marine organisms, and plants either in free state or as part of a peptide or depsipeptide. The importance of nonpeptidic ß-amino acids has been nfocused particularly on the ß-lactam antibiotics, since naturally occurring penicillin derivatives have been discovered as broad antibiotic active agents. Over the years, a large number of these compounds have been prepared and tested, and a variety of new ß-lactam ring systems have been introduced such as cephems, cephalosporins, oxacephems, penems, carbapenems, oxapenams as well as monocyclic and polycyclic ring systems. ß-Amino acids have been known to play an important role in primary and secondary metabolism also.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial peptides, containing alpha- and/or beta-amino acids with bulky substituents, can potentially possess some unusual properties, for example, decreased conformational ability or formation of stable secondary structures. Therefore, the preparation of such unnatural amino acids is of high interest. In this thesis, a route to enantiomerically pure 1-adamantylglycine was developed. The crucial step was the highly stereoselective addition of adamantylmagnesium bromide to the C=N bond of 2,3-O-cyclohexylidene-D-glyceraldehyde N-benzylnitrone effected in the presence of Lewis acid. Finally, 1-adamantylglycine was synthesized in 28 % yield over 6 steps. The routes to 9-aminofluorenylacetic and beta-aminobeta, beta-diphenylpropionic acids were proposed and they consist in the addition of allyl Grignard reagents to imines with various protecting groups, followed by oxidative transformation of the allyl group. Also some procedures for the preparation of 3,3-disubstituted 4-azetidinones, direct precursors of the corresponding beta-branched beta-amino acids, have been investigated.

Book Synopsis Unnatural Amino Acids by : Loredano Pollegioni
Download or read book Unnatural Amino Acids written by Loredano Pollegioni and published by Humana Press. This book was released on 2011-10-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even though they are present in nature, non-proteinogenic amino acids are usually defined as unnatural or non-natural. Beside their structural diversity, interest in these compounds is due to their occurrence in nature, their biological properties, the analytical aspects, their use as probes, and their incorporation into peptides and proteins, among other reasons. Divided into five convenient sections, Unnatural Amino Acids: Methods and Protocols deals with enzymatic methods used to produce non-natural amino acids, aspects concerning the presence of unnatural amino acids in peptides with antimicrobial properties, genetic incorporation of unnatural amino acids into proteins (yeast and mammalian cells), and detection and quantification of D-amino acids and related enzymes. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Unnatural Amino Acids: Methods and Protocols serves as an ideal guide for scientists and contributes to directing the attention of researchers to the many fields of growing scientific interest in non-natural amino acids.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2014 in the subject Chemistry - Bio-chemistry, grade: 1,0, LMU Munich (Chemie), language: English, abstract: In the present work a modified version of yellow fluorescent protein containing an unnatural structural homologue of the natural amino acid pyrrolysine with a norbornene moiety was produced by expression in Escherichia coli. The incorporation of the unnatural amino acid was achieved by amber stop codon suppression method. A bio-othogonal click reaction was performed, binding a synthetic fluorescent dye to the modified protein. All steps towards necessary for obtaining the genetically modified organism were performed and documented. The artificial amino acid, as well as the dye used in the click reaction were synthetically prepared. The success of the project was demonstrated by LC/MS studies of the products. Fluorescence spectroscopy of click reaction product and the protein was performed, but no conclusive proof of FRET effects could as yet be made. This point remains of interest for future studies.
