Phytochemical Compounds

Flavonoids are phytochemical compounds present in many plants, fruits, vegetables, and leaves, with potential applications in medicinal chemistry. Flavonoids possess a number of medicinal benefits, including anticancer, antioxidant, anti-inflammatory, and antiviral properties. They also have neuroprotective and cardio-protective effects. These biological activities depend upon the type of flavonoid, its (possible) mode of action, and its bioavailability. These cost-effective medicinal components have significant biological activities, and their effectiveness has been proved for a variety of diseases. The most recent work is focused on their isolation, synthesis of their analogs, and their effects on human health using a variety of techniques and animal models. Thousands of flavonoids have been successfully isolated, and this number increases steadily. We have therefore made an effort to summarize the isolated flavonoids with useful activities in order to gain a better understanding of their effects on human health.

Underlying Mechanisms

: Chronic Noncommunicable Diseases (NCDs), mostly represented by cardiovascular diseases, diabetes, chronic pulmonary diseases, cancers, and several chronic pathologies, are one of the main causes of morbidity and mortality, and are mainly related to the occurrence of metabolic risk factors. Anthocyanins (ACNs) possess a wide spectrum of biological activities, such as anti-inflammatory, antioxidant, cardioprotective and chemopreventive properties, which are able to promote human health. Although ACNs present an apparent low bioavailability, their metabolites may play an important role in the in vivo protective effects observed. : This article directly addresses the scientific evidences supporting that ACNs could be useful to protect human population against several NCDs not only acting as antioxidant but through their capability to modulate cell redox-dependent signaling. In particular, ACNs interact with the NF-κB and AP-1 signal transduction pathways, which respond to oxidative signals and mediate a proinflammatory effect, and the Nrf2/ARE pathway and its regulated cytoprotective proteins (GST, NQO, HO-1, etc.), involved in both cellular antioxidant defenses and elimination/inactivation of toxic compounds, so countering the alterations caused by conditions of chemical/oxidative stress. In addition, supposed crosstalks could contribute to explain the protective effects of ACNs in different pathological conditions characterized by an altered balance among these pathways. Thus, this review underlines the importance of specific nutritional molecules for human health and focuses on the molecular targets and the underlying mechanisms of ACNs against various diseases.

Objective. Fucosterol is derived from the brown alga Eisenia bicyclis and has various biological activities, including antioxidant, anticancer, and antidiabetic properties. The aim of this study was to investigate the protective effects of fucosterol pretreatment on Concanavalin A- (ConA-) induced acute liver injury in mice, and to understand its molecular mechanisms. Materials and Methods. Acute liver injury was induced in BALB/c mice by ConA (25 mg/kg), and fucosterol (dissolved in 2% DMSO) was orally administered daily at doses of 25, 50, and 100 mg/kg. The levels of hepatic necrosis, apoptosis, and autophagy associated with inflammatory cytokines were measured at 2, 8, and 24 h. Results. Fucosterol attenuated serum liver enzyme levels and hepatic necrosis and apoptosis induced by TNF-α, IL-6, and IL-1β. Fucosterol also inhibited apoptosis and autophagy by upregulating Bcl-2, which decreased levels of functional Bax and Beclin-1. Furthermore, reduced P38 MAPK and NF-κB signaling were accompanied by PPARγ activation. Conclusion. This study showed that fucosterol could alleviate acute liver injury induced by ConA by inhibiting P38 MAPK/PPARγ/NF-κB signaling. These findings highlight that fucosterol is a promising potential therapeutic agent for acute liver injury.

Some works of literature reported that fucoxanthin has diverse potential benefits for human health. Thus, this review would explain the sources of fucoxanthin, extraction techniques, bioactivities, and its potential application in Nutra- and cosmeceutical industries. Brown algae, such as Padina australis, Undaria pinnatifida; and the microalgae, such as Chaetoceros gracilis, Phaeodactylum tricornutum were sources of fucoxanthin. Then, the chemical structure of this xanthophyll is unique and that confers its biological activities. And then, the extraction process of fucoxanthin from macro- and microalgae is more safe, accessible, and economic, although this xanthophyll can be synthesized chemically. Generally, there are two techniques for the extraction of fucoxanthin, namely liquid solvent (conventional), and supercritical carbon dioxide (non-conventional) extractions. Furthermore, there are some bioactivities of fucoxanthin, including its activities of anticancer, antidiabetic, antiobesity, antioxidant; protective effects of skin, bone, and eyes. Based on in vivo assay of the animal, it has no adverse effects of fucoxanthin supplementation. Therefore, this xanthophyll might be applied in both the Nutra- and cosmeceutical industries. In the future, fucoxanthin and its derivatives would be important for human health, contributing to the beauty industry, and playing an important in the prevention of cancer and the disease related to lifestyle.

Gastrointestinal health is a precursor to general wellbeing in humans. Maintaining good normal gut flora for the health benefits they provide is important. Unfortunately, however, the good gut flora is sometimes dislodged during feeding and treatment with certain drugs. Foods that lead to such gut flora displacement may contain other microorganisms whose actions create unfavourable environmental conditions for resident flora. The principle of removing unwanted harmful gut flora; introducing good microorganisms through ingestion of live microorganisms, known as probiotics or foods that contain specific live microbes of interest is now practiced. Consumption of foods containing probiotics has long been practiced world-wide especially in rural settings and in low-income economies even though such consumptions may be unintended. Presently, careful isolation, characterization and testing of candidate probiotic organisms, has become the norm. This re-emerging phenomenon and the great impact it has on human health is considered here looking at probiotic sources; including foods, the role they play in gastrointestinal health, their mode of action and the disease types where they are beneficial to man including their safety and how their introduction in the �medical menu� in low-income nations can help in combating the rather very �regular� gastrointestinal infections in these countries.

The polysaccharides in many plants are attracting worldwide attention because of their biological activities and medical properties, such as anti-viral, anti-oxidative, antichronic inflammation, anti-hypertensive, immunomodulation, and neuron-protective effects, as well as anti-tumor activity. Denodrobium species, a genus of the family orchidaceae, have been used as herbal medicines for hundreds of years in China due to their pharmacological effects. These effects include nourishing the Yin, supplementing the stomach, increasing body fluids, and clearing heat. Recently, numerous researchers have investigated possible active compounds in Denodrobium species, such as lectins, phenanthrenes, alkaloids, trigonopol A, and polysaccharides. Unlike those of other plants, the biological effects of polysaccharides in Dendrobium are a novel research field. In this review, we focus on these novel findings to give readers an overall picture of the intriguing therapeutic potential of polysaccharides in Dendrobium, especially those of the four commonly-used Denodrobium species: D. huoshanense, D. offininale, D. nobile, and D. chrysotoxum.
