Antimicrobial Resistance: Omics and Systems Biology Approaches
by Vijay Soni Ajay Suresh AkhadeAntimicrobial resistance (AMR) is increasing globally at an incredible rate, and many infectious diseases have already reached an alarming stage of resistance to existing treatments. WHO reports that nearly1.27 million people currently die each year due to resistant infections, and AMR is projected to account for 10 million annual deaths globally by 2050. There is an urgent need for novel approaches to address this issue. Omics technologies are powerful research tools used extensively to study pathogen biology and the activity of microbial agents. These tools, paired with systems biology approaches, can provide novel insights into antimicrobial susceptibility and resistance, and aid in the development of new, more effective measures to combat resistant pathogens. This book provides a comprehensive overview of omics technologies to study pathogen biology, including proteomics, genomics, transcriptomics, metabolomics, and microbiome analysis, and the role of systems biology in developing strategies to combat resistant pathogens. It addresses environmental reservoirs and mobile genetic agents in AMR, host-pathogen interactions and physiology in the development of resistance, drug repurposing and development, and cutting-edge tools such as machine learning, AI for big data analysis, and genomic surveillance. The final section discusses future perspectives on omics-systems biology in AMR, and identifies opportunities for scientific collaboration in the global fight against antimicrobial resistance. This book serves as a comprehensive and accessible resource for researchers in academia and industry focused on immunology, drug development, biotechnology, and systems biology.

Antineoplastic Drugs
by Daniel LednicerThe past decade has seen a significant increase of research aimed at discovering new drugs for treating cancer, and the increasing number of new antineoplastic drugs approved by regulatory agencies reflects this. Until now, details on the synthesis of these newer agents have been scattered in various journals and in US and European patents. This timely volume deals with the organic chemistry involved in the synthesis of the agents found within antineoplastic drugs, including descriptions of the synthetic schemes for the preparation of over 200 compounds that have been granted non-proprietary names. Compounds are collected in chapters based on the mechanism of action rather than on their chemical structures. Each individual chapter is preceded by a brief description of that mechanism and includes detailed flow charts of the preparation of those compounds accompanied by discussions of the organic chemistry involved in each step. The first half of this volume is dedicated to the syntheses of established chemotherapy drugs. Kinase inhibitors occupy the following chapters with the largest single chapter dealing with the fifty compounds that inhibit tyrosine kinase. This class stands out since over twenty compounds in this group have been approved for treating patients; a rare track record compared to any other class of therapeutic agents. Antineoplastic Drugs: Organic Syntheses is written to appeal to organic and medicinal chemists in industry and academia. It is beneficial to those composing grant proposals for NCI and related organizations. The book is accessible to advanced undergraduates as well as graduates and researchers as well as those with a thorough grasp of organic chemistry.
Antioxidant Defense in Plants: Molecular Basis of Regulation
by Tariq Aftab Khalid Rehman HakeemThis edited book highlights the molecular basis of various enzymatic and non-enzymatic antioxidants, defense mechanisms and adaptation strategies employed by plants to avoid the stressful conditions. Special focus is given to gene expression, omics and other latest technologies such as CRISPR-Cas mediated genome editing applications for defense related studies in plants. Environmental stresses such as drought, salinity or floods etc. induce the generation of reactive oxygen species (ROS) which causes severe damage to cell membrane integrity by accelerating lipid peroxidation. To counteract the detrimental effect of ROS, plants are inherited with an intricate and vibrant antioxidant defense system, comprised of enzymatic (catalase, peroxidase, superoxide dismutase, glutathione reductase, glutathione S-transferase, guaiacol peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase etc.), and non-enzymatic (glutathione, ascorbate, α-tocopherol, carotenoids, flavonoids etc.) antioxidants, which scavenge and/or reduce excess ROS and improve plant tolerance to various stresses. Stress tolerance in most crop plants is positively correlated with an efficient antioxidant system. Therefore, studying the efficiency of antioxidant defense systems in plants is necessary for facilitating the plant’s nature of adaptation against challenging environments. This book is of interest to teachers, researchers and academic experts. Also, the book serves as additional reading material for undergraduate and graduate students of biotechnology and molecular biology of plants.

Antioxidants and Antioxidant Enzymes in Higher Plants
by Francisco J. Corpas Dharmendra K. Gupta José M. PalmaThis book provides an overview of antioxidants and antioxidant enzymes and their role in the mechanisms of signaling and cellular tolerance under stress in plant systems. <P><P> Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors. <P> Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology.
