This book was released on 2017 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibiotic resistance has been a developing problem for mankind in recent decades and multi-drug resistant bacteria are now encountered that are resistant to all treatment options available. In 2014, the World Health Organization announced that this problem is driving us towards a “post-antibiotic era” that will change the face of modern medicine as we know it. If lack of novel antibiotic development and FDA approval continues, by the year 2050, 10 million people will die each year to an antimicrobial resistant bacterial infection. With lack of pharmaceutical industry involvement in developing novel antibiotics, the responsibility now lies within the academic institutions to identify potential novel therapeutics to fuel the antibiotic drug discovery pipeline. Combinatorial chemistry is one technique used to expedite the discovery process by assessing a large chemical space in a relatively short time when compared to traditional screening approaches. Combinatorial libraries can be screened using multiple approaches and has shown successful application towards many disease states. We initially discovered broad spectrum antibacterial bis-cyclic guanidines using combinatorial libraries and expanded on the knowledge of the physiochemical attributes necessary to inhibit Gram negative bacterial pathogens. Following this success, we continued to assess the combinatorial libraries for adjunctive therapeutics that potentiate the activity of obsolete clinical antibiotics. The polyamine efflux pump inhibitors discovered in this subsequent study prove the benefits of using the large chemical space provided in the combinatorial libraries to identify a variety of therapeutics. Our studies always begin with identifying an active compound and active compounds undergo hit-to-lead optimization. This optimization studies are of utmost importance in developing a novel antibacterial agent for therapeutic applications. Our medicinal chemistry work described here is proof of the success of careful structure activity analyses to optimize a hit scaffold to create a more effective antibacterial agent. Overall, our work described here reveals the potential role of academic institutions in fending off the impending “post-antibiotic era”.

Available in PDF, EPUB and Kindle. Book excerpt: Antibiotics represent one of the most successful forms of therapy in medicine. But the efficiency of antibiotics is compromised by the growing number of antibiotic-resistant pathogens. Antibiotic resistance, which is implicated in elevated morbidity and mortality rates as well as in the increased treatment costs, is considered to be one of the major global public health threats (www.who.int/drugresistance/en/) and the magnitude of the problem recently prompted a number of international and national bodies to take actions to protect the public (http://ec.europa.eu/dgs/health_consumer/docs/road-map-amr_en.pdf: http://www.who.int/drugresistance/amr_global_action_plan/en/; http://www.whitehouse.gov/sites/default/files/docs/carb_national_strategy.pdf). Understanding the mechanisms by which bacteria successfully defend themselves against the antibiotic assault represent the main theme of this eBook published as a Research Topic in Frontiers in Microbiology, section of Antimicrobials, Resistance, and Chemotherapy. The articles in the eBook update the reader on various aspects and mechanisms of antibiotic resistance. A better understanding of these mechanisms should facilitate the development of means to potentiate the efficacy and increase the lifespan of antibiotics while minimizing the emergence of antibiotic resistance among pathogens.

Download or read book Antibiotic Discovery Targeting Bacterial GroEL GroES Chaperonin Systems written by Trent A. Kunkle and published by . This book was released on 2018 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Centers for Disease Control (CDC) and World Health Organizations (WHO) have highlighted six species of highly drug-resistant bacteria, commonly termed the ESKAPE pathogens, that new antibacterials are urgently needed to treat). The ESKAPE pathogens account for over two-million infections and have healthcare costs upwards of $20 billion dollars annually. Over the past several decades, pharmaceutical companies have drastically reduced their research programs for developing new antibacterial agents. As well, bacteria are predisposed to rapidly generate resistance against these "me too" drugs, making this strategy a temporary stop-gap in our ability to fight these pathogens. This has left the burden to identify new antibiotics that function through fundamentally unique mechanisms of action to academia. Towards this goal, we are developing a unique antibacterial strategy that functions through targeting the bacterial GroEL chaperonin systems. GroEL is a molecular chaperone that helps fold proteins into their functional states. Being an essential protein, inhibiting GroEL activity leads to global aggregation and bacterial cell death. We previously reported a high-throughput screening effort that identified 235 GroEL inhibitors. A subsequent study with a subset of these inhibitors identified several that kill bacteria. To follow-up, we have synthesized 43 analogs of a hit-to-lead molecule, compound 1, containing systematic deletions of substituents and substructures to determine the essential parts of the scaffold for inhibiting GroEL and killing bacteria. Along with inhibiting GroEL, several compound 1 analogs exhibit>50-fold therapeutic windows between antibacterial efficacy and cytotoxicity to human liver and kidney cells in cell culture. Evaluation of two lead candidates (1 and 11) in a gain-of-resistance assay indicated that MRSA bacteria were not able to easily generate resistance to this compound class. Compound 1 also exhibited the ability to permeate through already established S. aureus biofilms and maintain its bactericidal effects, whereas vancomycin could not. Having established initial structure-activity relationships for the compound 1 substituents and substructures in this study, future efforts will focus on optimizing the antibacterial effects of lead candidates and reducing their off-target toxicity to human cells

Download or read book Combination Therapy Against Multidrug Resistance written by Mohmmad Younus Wani and published by Academic Press. This book was released on 2020-04-30 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combination Therapy against Multidrug Resistance explores the potential of combination therapy as an efficient strategy to combat multi-drug resistance. Multidrug resistance (MDR) occurs when microorganisms such as bacteria, fungi, viruses, and parasites are excessively exposed to antimicrobial drugs such as antibiotics, antifungals, or antivirals, and in response the microorganism undergoes mutations or develops different resistance mechanisms to combat the drug for its survival. MDR is becoming an increasingly serious problem in both developed and developing nations. Bacterial resistance to antibiotics has developed faster than the production of new antibiotics, making bacterial infections increasingly difficult to treat, and the same is true for a variety of other diseases. Combination therapy proves to be a promising strategy as it offers potential benefits such as a broad spectrum of efficacy, greater potency than the drugs used in monotherapy, improved safety and tolerability, and reduction in the number of resistant organisms. This book considers how combination therapy can be applied in multiple situations, including cancer, HIV, tuberculosis, fungal infections, and more. Combination Therapy Against Multidrug Resistance gathers the most relevant information on the prospects of combination therapy as a strategy to combat multridrug resistance and helping to motivate the industrial sector and government agencies to invest more in research and development of this strategy as a weapon to tackle the multidrug resistance problem. It will be useful to academics and researchers involved in the development of new antimicrobial or antiinfective agents and treatment strtategies to combat multidrug resistance. Clinicians and medical nurses working in the field of infection prevention and control (IPC) will also find the book relevant - Explores strategic methods with investigation of both short- and long-term goals to combat multidrug resistance - Presents a broad scope to understand fully the ways to apply combined therapy to multidrug resistance - Provides an overview of combination therapy, but also includes specific cases such as cancer, tuberculosis, HIV and malaria
