Phytochemicals refer to a large group of non-nutritious but bioactive compounds derived from plant foods including fruits, vegetables, and grains. Due the considerable diversity in their chemical structures, phytochemicals can be divided into phenolic compounds, carotenoids, terpenoids, organosulfur glucosinolates, saponins, phytoestrogens, phytic acid, phytosterols, etc. are not only important for growth, also helpful plants survive under various environmental stresses resist infections viruses, bacteria, yeasts, fungi. At same time, beneficial roles improving human health, such as protecting against coronary heart disease, diabetes, cancers, hypertension, inflammation, other chronic diseases, have gained increasing interest recent years. In this chapter, we summarized definition, classification, physicochemical property, pharmacokinetics, biological effects, health functions phytochemicals.

The ancient Egyptians practiced medicine with highly professional methods. They had advanced knowledge of anatomy and surgery. Also, they treated a lot diseases including dental, gynecological, gastrointestinal, urinary disorders. could diagnose diabetes cancer. used therapeutics extended from different plants to include several animal products minerals. Some these are still in the present day. Fortunately, documented their life details by carving on stone, clay, or papyri. Although records have been lost destroyed, surviving documents represent huge source scientific aspects medicine. This review article is an attempt understand some information about traditional Egypt, we will look closely at basics, sources Egyptian addition common this great civilization.

Ethnopharmacology, through the description of beneficial effects plants, has provided an early framework for therapeutic use natural compounds. Natural products, either in their native form or after crude extraction active ingredients, have long been used by different populations and explored as invaluable sources drug design. The transition from traditional ethnopharmacology to discovery followed a straightforward path, assisted evolution isolation characterization methods, increase computational power, development specific chemoinformatic methods. deriving extensive exploitation product chemical space led novel compounds with pharmaceutical properties, although this was not analogous drugs. In work, we discuss ideas silico discovery, applied products. We point out that, past, starting plant itself, identified sustained ethnopharmacological research, compound analysis testing. contrast, recent years, substance pinpointed methods (in docking molecular dynamics, network pharmacology), identification plant(s) containing ingredient, existing putative information. further stress potential pitfalls absolute need vitro vivo validation requirement. Finally, present our contribution products' discussing examples, applying whole continuum rapidly evolving field. detail, report antiviral compounds, based on products against influenza SARS-CoV-2 substances GPCR, OXER1.

Panax ginseng C. A. Meyer (P. ginseng) has a long history of medicinal use and can treat variety diseases. P. contains active ingredients, such as saponins, polypeptides, volatile oils, polysaccharides. Among them, saponins have always been considered the main components responsible for its pharmacological activities. However, more studies shown that polysaccharides play an indispensable role in value ginseng. Modern biological medical found complex structural characteristics diverse activities, immune regulation, anti-tumor, antioxidant, hypoglycemic, anti-radiation functions, among others. Additionally, are closely related to their activity. In this review, research background, extraction, purification, characteristics, activities from different parts (roots, flowers stems leaves, berries) under growth conditions (artificially cultivated ginseng, mountain wild summarized. The purified were reviewed. Meanwhile, introduced, some possible mechanisms listed. Furthermore, structure-activity relationship was discussed. Some perspectives study also provided.

In continuation of our antecedent work against COVID-19, three natural compounds, namely, Luteoside C (130), Kahalalide E (184), and Streptovaricin B (278) were determined as the most promising SARS-CoV-2 main protease (Mpro) inhibitors among 310 naturally originated antiviral compounds. This was performed via a multi-step in silico method. At first, molecular structure similarity study done with PRD_002214, co-crystallized ligand Mpro (PDB ID: 6LU7), favored thirty Subsequently, fingerprint respect to PRD_002214 resulted election sixteen compounds (7, 128, 130, 156, 157, 158, 180, 184, 203, 204, 210, 237, 264, 276, 277, 278). Then, results docking versus PDB 6LU7 eight (128, 278) based on their binding affinities. toxicity studies for revealed that all them have good profiles. Finally, dynamic (MD) simulation experiments carried out 278, which exhibited best modes Mpro. MD tests luteoside (130) has greatest potential inhibit protease.

Among a group of 310 natural antiviral metabolites, our team identified three compounds as the most potent inhibitors against SARS-CoV-2 main protease (PDB ID: 5R84), Mpro. The are sattazolin and caprolactin A B. validated multistage in silico study was conducted using several techniques. First, molecular structures selected metabolites were compared with that GWS, co-crystallized ligand Mpro, structural similarity study. aim this to determine thirty similar (10%) may bind Mpro GWS. Then, docking pharmacophore studies led choice five exhibited good binding modes fit values generated model. them, chosen according ADMET studies. promising inhibitor determined by toxicity DFT be (292). Finally, dynamics (MD) simulation performed for confirm obtained results understand thermodynamic characteristics binding. It is hoped accomplished could represent positive step battle COVID-19 through further vitro vivo on compounds.

Ginsenosides are a class of active components extracted from ginseng plants (such as Panax ginseng, quinquefolium, and notoginseng). have significant protective effects on the nervous system, cardiovascular immune so they been widely used in treatment related diseases. Entry variety endogenous or exogenous harmful substances into body can lead to an imbalance between antioxidant defense system reactive oxygen species, thus producing toxic tissues cells. In addition, oxidative stress alter multiple signaling pathways, including Keap1/Nrf2/ARE, PI3K/AKT, Wnt/β-catenin, NF-κB pathways. With deepening research this field, various ginsenoside monomers reported exert through pathways good application prospects. This article summarized advancements regarding antioxidative mechanisms ginsenosides, providing theoretical basis for experimental clinical with ginsenosides.
