Available in PDF, EPUB and Kindle. Book excerpt: The review on antiviral anti-hepatitis A virus agents is warranted given the importance of hepatitis A virus (HAV) as a human pathogen. Novel antiviral drugs have been sourced from natural agents and developed into products for management of viral infections. The role of purified natural products in treatment and as adjunctives in the management of HAV infections is clearly plausible. Treatments against Hepatitis A virus infection is currently limited. In this chapter, the antiviral natural products against hepatitis-A virus (HAV), their sources as well as their treatment approach and their application have been discussed. The antiviral natural products could be sourced generally from plants, herbs and animals. These natural agents have been shown to demonstrate substantial antiviral activity against HAV and could target various stages of the viral life cycle, replication, assemblage, release, as well as targeting virus-host specific interactions.

Chapters cover such topics as pathology, epidemiology, at-risk populations, animal research models, and future trends.

Download or read book Herbal Anti Viral and Anti Biotics written by Lisa H Gregory Ph D and published by . This book was released on 2021-01-18 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibiotics are used to kill or inhibit bacteria growth. Although you might think of antibiotics as modern medicine, they've actually been around for centuries. The original antibiotics, like a lot of today's antibiotics, are derived from natural sources. Certain plant extracts, essential oils, and even foods have antibiotic properties. For example, some food and vegetable extracts can prevent the growth of bacteria in food. Sometimes, these properties extend beyond the food and can aid in your personal hygiene. Cranberry extract contains both antibacterial and antioxidant compounds, making it a home remedy for urinary tract infections (UTIs). Herbs can be antibiotics, too. A small sampling study of 58 Chinese plants found that 23 had antibacterial properties and 15 had antifungal properties. A 2014 found that an herbal therapy was just as effective as a chemical antibiotic in treating a small intestine bacterial overgrowth disorder. Viruses are responsible for a number of human pathogeneses including cancer. Several hard-to-cure diseases and complex syndromes including Alzheimer's disease, type 1 diabetes, and hepatocellular carcinoma have been associated with viral infections. Moreover, due to increased global travel and rapid urbanization, epidemic outbreaks caused by emerging and re-emerging viruses represent a critical threat to public health, particularly when preventive vaccines and antiviral therapies are unavailable. Examples include the recent emergence of dengue virus, influenza virus, measles virus, severe acute respiratory syndrome (SARS) virus, and West Nile virus outbreaks. To date, however, many viruses remain without effective immunization and only few antiviral drugs are licensed for clinical practice. The situation is further exacerbated by the potential development of drug-resistant mutants, especially when using viral enzyme-specific inhibitors, which significantly hampers drug efficacy. Hence, there is an urgent need to discover novel antivirals that are highly efficacious and cost-effective for the management and control of viral infections when vaccines and standard therapies are lacking. Herbal medicines and purified natural products provide a rich resource for novel antiviral drug development. Identification of the antiviral mechanisms from these natural agents has shed light on where they interact with the viral life cycle, such as viral entry, replication, assembly, and release, as well as on the targeting of virus-host-specific interactions. In this brief report, we summarize the antiviral activities from several natural products and herbal medicines against some notable viral pathogens including coronavirus (CoV), coxsackievirus (CV), dengue virus (DENV), enterovirus 71 (EV71), hepatitis B virus (HBV), hepatitis C virus (HCV), herpes simplex virus, human immunodeficiency virus (HIV), influenza virus, measles virus (MV), and respiratory syncytial virus (RSV)

Download or read book Natural Antimicrobial Agents written by Jean-Michel Mérillon and published by Springer. This book was released on 2018-02-08 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Documenting the latest research in the field of different pathogenic organisms, this book presents the current scenario about promising antimicrobials in the following areas: Part I. Plants as source of antibacterials, Part II. Naturally occurring antifungal natural products, Part III. Antiparasitic natural products, Part IV. Antiviral natural products. Renowned scientists from the globe have been selected as authors to contribute chapters. Use of plants for various ailments is as old as human civilization and continuous efforts are being made to improve medicinal plants or to product their bioactive secondary metabolites in high amounts through various technologies. About 200,000 natural products of plant origin are known and many more are being identified from higher plants and micro-organisms. Some plants based drugs are used since centuries and there is no alternative medicine for many such drugs as cardiac glycosides. Drug discovery from medicinal plants or marine micro-organisms continues to provide an important source of new drug leads. Research on new antibacterials represents a real and timely challenge of this century, particularly for the treatment of infections caused by clinical isolates that show multidrug resistance. The main microorganisms involved in the resistance process have been identified and given the acronym ESKAPE for Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanii, Pseudomonas aeruginosa and Enterobacteriaceae. Multidrug resistant Mycobacterium tuberculosis including highly drug-resistant strains (XDR-TB) has also emerged as one of the most important clinical challenges of this century. Plants of diverse taxa and marine micro-organisms are rich source of these antimicrobials. An attempt has been made to compile the recent information about natural sources of antibacterials and their sustainable utilization. Increased panic of these pathogens warrants a growing demand for research to undertake the threat of multidrug resistance. The search for new antifungal, antiparasitic and antiviral natural products is far from devoid of interest. According to the WHO report in 2013, malaria still represents some 207 million cases worldwide and more than 3 billion of people are still exposed to this risk. Similarly, about 350 million people are considered at risk of contracting leishmaniasis. The fight against some viruses also requires that the research on natural products continue. For example, even if an antiretroviral with direct action was recently approved in Europe in 2013, its high cost does not allow to offer it to an exposed population in countries where the cost of drugs remains a problem for a large part of the population. These books are useful to researchers and students in microbiology, biotechnology, pharmacology, chemistry and biology as well as medical professionals.
