Abstract

The nature is a generous source of a number of compounds with potential application for the treatment of several diseases including the infectious diseases, which is of utmost concern for the modern medicine due to the observed striding antimicrobial resistance. A number of sources of natural compounds with valuable and clinical antimicrobial activity can be listed, comprising medicinal plants, marine and terrestrial organisms, which includes fungi and bacteria. Nevertheless, there is still a vast fauna and flora that, once systematically explored, could provide additional antimicrobial leads and drugs. Investigators were invited to contribute with original research and/or review articles on this area, specifically with studies exploiting the mechanism of action and the structure-activity aspects of natural compounds with antimicrobial activity that provides insights on potential ways to overcome the antimicrobial resistance. Therefore, thanks to the contribution of active researchers in the field, several scientific studies mainly focused on natural products with antimicrobial activity are presented in this Research Topic Ebook.

Abstract

Natural and chemical compounds, often used as both dietary supplements and alternative medicines, are characterized by specific chemical properties, allowing their passage across the blood brain barrier with consequent specific effects on neurotransmission. In particular, several natural compounds have shown beneficial properties in the treatment of neuropsychiatric disorders, especially cognitive impairment and mood disorders, contributing to the maintenance of the physiological brain functioning by interacting with different receptors, transcription factors and signal transduction pathways. Neuroinflammation and oxidative stress have also been proposed as crucial contributors to brain dysfunction development, thus recent investigations have focused on novel therapeutic approaches based on the use of phytoderivates with neuroprotective properties. Thus, this Special Issue includes a collection of 11 papers, describing key findings for the identification of molecular mechanisms required for the development of potential and promising natural therapeutics for the treatment of psychiatric and neurodegenerative disorders.

Abstract

In Western countries, cancer is among the most frequent causes of death. Despite striking advances in cancer therapy, especially by the so called “targeted agents”, there is still an urgent need for new drugs in oncology. Hope comes from the marine environment, which is a rich source of natural compounds showing anti-cancer activity. To date, four marine cytotoxic substances, namely cytarabine, trabectidine, eribulin, and monomethyl auristatin E (as a drug-antibody conjugate named vedotin) have made it into clinical routine. Many more are in all phases of clinical testing, and a plethora of substances has already been examined for in vitro and in vivo activity.Interestingly, more and more precise research tools allow the dissection of the molecular mode of action of these cytotoxic substances, thereby uncovering the specific drug targets in cancer cells. This development will blur the edges between “targeted” and “untargeted” therapy, and will hopefully lead to a more directed use of cancer medicine (based on a molecular rationale of activity) in the future.This Topical Collection will cover the whole scope from agents with cancer-preventive activity, to novel and previously characterized compounds with anti-cancer activity, both in vitro and in vivo, and the latest status of clinical development from drug trials. Of note, compounds possessing pro-carcinogenic activity or mediating cancer cell survival are also within the scope of this Topical Collection. In addition, a special focus will be placed on current shortfalls and possible strategies to overcome obstacles in the area of marine anti-cancer drug development.

Abstract

Obesity and related co-morbidities are increasing worldwide and pose a serious health problem. Changes in lifestyle and diet would be the best remedies to fight obesity; however, many people will still rely on medical aid. Marine organisms have been prolific in the production of bioactive compounds for many diseases, e.g., cancer, and promise to be an excellent source for natural-derived molecules and novel nutraceuticals. Bioactive compounds with beneficial activities towards obesity have been described from diverse marine organism including marine algae, bacteria, sponges, fungi, crustaceans or fish. This Special Issue will highlight the progress in the following topics: Bioactive compounds for the treatment of obesity and obesity-related co-morbidities (diabetes, fatty liver, hyperlipidemia) from marine organisms; the isolation of novel compounds, the bioactivity screening of marine organisms and the elucidation of molecular mode of action of marine bioactive compounds.

Abstract

Throughout most of history, medicinal plants and their active metabolites have represented a valuable source of compounds used to prevent and to cure several diseases. Interest in natural compounds is still high as they represent a source of novel biologically/pharmacologically active compounds. Due to their high structural diversity and complexity, they are interesting structural scaffolds that can offer promising candidates for the study of new drugs, functional foods, and food additives.Plant extracts are a highly complex mixture of compounds and qualitative and quantitative analyses are necessary to ensure their quality. Furthermore, greener methods of extraction and analysis are needed today.This book is based on articles submitted for publication in the Special Issue entitled “Qualitative and Quantitative Analysis of Bioactive Natural Products” that collected original research and reviews on these topics.
