Abstract

This book “Oxidative Stress Modulators and Functional Foods” is focused on the antioxidant role of natural products, involving their ability to modulate oxidative stress and/or reverse disease studied both in vitro and in animal models. Additionally, the molecular mechanisms of these actions and the modulation of signalling pathways related to inflammation, apoptosis, and survival response in the redox system by natural products are included.

Abstract

Fucoidans are a group of fucose-containing sulfated polysaccharides found in many species of brown seaweeds, with numerous bioactive properties. As a highly bioactive seaweed substance with many promising physiological activities, fucoidans have attracted attention from many industries all over the world. Even though fucoidans are a rich source of bioactive properties, the structural properties and bioactive mechanisms of fucoidans are poorly understood. Therefore, novel studies that either characterize the physical properties or biological activities of fucoidans will fill the knowledge gap between industrial applications and the scientific background of those applications. Both purified and partially purified fucoidans isolated from brown seaweeds present high potential as preventative and therapeutic agents against number of chronic diseases, due to their anti-inflammatory, antioxidant, anticancer, neuroprotective, antiviral, antimicrobial, and anticoagulative properties. This Special Issue is aimed at presenting updated information on well-documented studies of the structural characterization and major biological actions relevant for medical, cosmeceutical, and pharmaceutical applications that fucoidans isolated from brown seaweed can offer.

Abstract

Cancer is the second leading cause of death worldwide, and was accountable for an estimated 9.6 million deaths in 2018. Nowadays, about 1 in 6 deaths in the world is due to cancer. Another major global public health issue is HIV. Over 70 million people have been infected with the HIV virus and about 35 million people have died of HIV-related illness, since the start of the epidemic. We have been fighting against these two serious diseases by finding successful treatments. The discovery of effective drugs is important for fighting cancer and HIV. Natural products, which are secondary metabolites produced by various living organisms, have been playing a principal role in drug discovery and developments, because of their structural and biological diversity. Many clinically used drugs have come from natural products; for example, more than 60% of anticancer drugs currently in clinical use are derived from natural sources. This Special Issue aims to collect original research and review articles focusing on notable and recent contributions to the discovery and development of novel anticancer and anti-HIV drug candidates from natural sources. Up-to-date knowledge from various research fields is welcome. This could be of great interest for scientists working in different research areas, such as natural product chemistry, including isolation and structural elucidation; phytochemistry; medicinal chemistry, including chemically modified natural compounds with improved biological activity; pharmacology; molecular biology; mechanisms of action study using natural products or related compounds; pharmacognosy, etc. Biological studies of natural extracts without an appropriate chemical characterization may not be considered.

Abstract

Based on their potent antioxidant properties, the possible exploitation of natural phenolic compounds as food supplements as well as functional ingredients in the food and cosmetic industry is gaining more and more attention. This book contains original research articles and a review reporting innovative applications of natural phenolic compounds in the field of nutrition and biomedicine, as active ingredients for the prevention of oxidative-stress-related diseases, and as additives in smart food packaging, biomedical devices, and cosmetic products. The growing importance of agri-food wastes as easily accessible sources of phenolic compounds as well as of synthetic derivatives of natural compounds with improved antioxidant properties is also highlighted. Finally, novel technologies to improve extraction yields, stability, bioavailability, and delivery of antioxidant compounds for healthcare products or for skin applications are described.
