Download or read book Amino Acids Insights and Roles in Heterocyclic Chemistry written by Zerong Wang and published by CRC Press. This book was released on 2023-05-26 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume of a first-of-its-kind four-volume book set that provides readers with up-to-date information on α-amino acids, the potential challenges in working with α-amino acids, the protecting groups for the carboxyl, amino and side chain groups of the amino acids, and the most popular heterocyclic compounds that are originating from alpha-amino acids. These heterocyclic compounds include hydantoins, thiohydantoins (including 2-thiohydantoins, 4-thiohydantoins, 2,4-dithiohydantoins), 2,5-diketopiperazines, N-carboxyanhydrides, N-thiocarboxyanhydrides, sydnones, sydnonimines, azlactones, pseudoazlactones, and oxazolidin-5-ones. This is the first resource to comprehensively collect all the heterocycles that can be directly prepared from α-amino acids. In addition, almost all kinds of synthetic methods for a particular type of heterocycles from alpha-amino acids are included, along with the detailed mechanistic discussions and experimental procedures. In Volume 2: Hydantoins, Thiohydantoins, and 2,5-Diketopiperazines compiles the three IUPAC accepted nomenclature systems for heterocyclic compounds, which will be very useful for readers working in the heterocyclic chemistry field for giving synthesized molecules their correct names. In addition, three groups of heterocyclic compounds, i.e., hydantoins, thiohydantoins (including 2-thiohydantoin, 4-thiohydantoin and 2,4-dithiohydantoin), and 2,5-diketopiperazines, have been organized with updated literature information. Particularly, all three groups of heterocyclic compounds have demonstrated many important biological activities, particularly anticancer and antibacterial activities. On the other hand, these three groups of heterocycles can be applied as substrates to make other chemical derivatives, particularly novel unnatural amino acids. All their reactivities have been compiled and updated. The other volumes include: Volume 1: Protecting Groups Volume 3: N-Carboxyanhydrides, N-Thiocarboxyanhydrides, and Sydnones Volume 4: Azlactones and Oxazolidin-5-ones All together, this unique 4-volume set thoroughly covers the two types of heterocyclic compounds that are originated from alpha-amino acids, providing carefully compiled updated information with detailed examples. The author has shared many thoughtful insights based on his strong background in physical organic chemistry. The volumes will be highly valuable for graduate students and senior students, as well as for professors and researchers working in the field of medicinal and pharmaceutical chemistry, organic chemistry, organic synthesis, heterocycles, and proteins and peptides.

Download or read book Oral Cephalosporins written by Robert C. Moellering and published by S Karger Ag. This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an excellent survey of the chemistry, microbiology, pharmacology and clinical use of the oral cephalosporins in general and the newer agents in particular. The cephalosporins have long provided satisfactory treatment for many disorders without causing serious side effects; and over the past fifty years forms with different antimicrobial, pharmacologic and toxicologic properties have been developed. Despite the broad spectrum of their activity against a large variety of gram-positive and gram-negative bacteria, the third-generation oral cephalosporins including the prodrug esters do not work against Pseudomonas aeruginosa, methicillin-resistant staphylococci, enterococci or Bacteroides species. Many, however, are suitable for treating infections of the respiratory and urinary tracts and of the skin and its structure, as well as certain sexually-transmitted diseases. Authors consider other possible uses, against multi-resistant Enterobacteriaceae for instance, but also point out the limitations of the oral cephalosporins. For those working in the fields of infectious disease, bacteriology, chemotherapy, pharmaceutics and pharmacokinetics, this book is a valuable source of authoritative information.

Download or read book Penicillins and Cephalosporins written by Robert B. Morin and published by Academic Press. This book was released on 2014-05-10 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and Biology of ?-Lactam Antibiotics, Volume 1: Penicillins and Cephalosporins provides information pertinent to the study of antibiotics containing the ?-lactam moiety. This book discusses the occurrence of a group of ?-lactam antibiotics structurally related to cephalosporin C. Organized into five chapters, this volume begins with an overview of the mechanism of action of ?-lactam antibiotics that caused many microbiologists to develop screening tools for the detection of the ?-lactam moiety. This text then discusses the discovery of the nocardicins, the thienamycins, and olivanic acids. Other chapters provide a summary of the essential penicillin sulfoxide chemistry that gave rise to many compounds. This book discusses as well the ability of chemists to predict the level of biological activity of a compound from knowledge of its structure through theoretical and physicochemical studies. The final chapter deals with quantitative structure–activity relationships. This book is a valuable resource for microbiologists, chemists, and scientists.
