Both compounds have health-promoting properties, but the latter undergoes rapid metabolization and has low bioavailability. O-methylation improves the stability and bioavailability of resveratrol. In plants, these reactions are performed by O-methyltransferases (OMTs).

Over the past 27 years numerous clinical studies have found a linkages with the ANTIOXIDANTS in particular, the POLYPHENOLS, RESVERATROL, CATECHINS, QUERCERTIN and ANTHOCYANDINS in red wine and reduced incidences of cardiovascular disease. However, the alcohol in wine limits the benefits of wine. Studies have shown that zero alcohol red wine and red wine extract which contain the same ANTIOXIDANTS including POLYPHENOLS, RESVERATROL, CATECHINS, QUERCERTIN and ANTHOCYANDINS has the same is not more positive health benefits. The following literature review details some of the most recent positive health benefits derived from the ANTIOXIDANTS found in red wine POLYPHENOLS: RESVERATROL, CATECHINS, QUERCERTIN and ANTHOCYANDINS. The positive polyphenolic antioxidant effects of the polyphenols in red wine include: • Cardio Vascular Health Benefits • Increase antioxidants in the cardiovascular system • Assisting blood glucose control • Skin health • Bone Health • Memory • Liking blood and brain health • Benefits

Although the biosynthetic pathway of resveratrol has been fully elucidated, the characterization of resveratrol-specific O-methyltransferases remains elusive. In this study, we used RNA-seq analysis to identify a putative aromatic O-methyltransferase gene, AcOMT1,inAcorus calamus. Recombinant AcOMT1 expressed in Escherichia coli showed high 40-O-methylation activity toward resveratrol and its derivative, isorhapontigenin. We purified a reaction product enzymatically formed from resveratrol by AcOMT1 and confirmed it as 40-O-methylresveratrol (deoxyrhapontigenin). Resveratrol and isorhapontigenin were the most preferred substrates with apparent Km values of 1.8 mM and 4.2 mM, respectively. Recombinant AcOMT1 exhibited reduced activity toward other resveratrol derivatives, piceatannol, oxyresveratrol, and pinostilbene. In contrast, re- combinant AcOMT1 exhibited no activity toward pterostilbene or pinosylvin. These results indicate that AcOMT1 showed high 40-O-methylation activity toward stilbenes with non-methylated phloroglucinol rings.

Here, the anti-tumorigenic properties of resveratrol and structural analogues oxyresveratrol, pinos- Resveratrol tilbene, pterostilbene and tetramethoxystilbene (TMS) were studied in vitro, using in the malignant human MCF- 7 breast cancer cell line and non-tumorigenic breast epithelial cell line MCF-10A. Cell viability and migration assays showed that methoxylated analogues of resveratrol are more potent anti- tumorigenic compounds than resveratrol and its hydroxylated analogue oxyresveratrol, with 2,3’,4,5’-tetra- methoxy-trans-stilbene (TMS) being the most potent compound. TMS decreased MCF-7 tumor cell viability with 50% at 3.6 μM and inhibited migration with 37.5 ± 14.8% at 3 μM. In addition, TMS activated the AHR more potently (EC50 in a reporter gene assay 2.0 μM) and induced AHR-mediated induction of cytochrome P450 1A1 (CYP1A1) activity (EC50 value of 0.7 μM) more than resveratrol and the other analogues tested.

Epidemiological, clinical, and nutritional studies from recent years have confirmed the significant biological effects of stilbenoids, such as oxidative stress protection and the prevention of degenerative diseases, including cancer, cardiovascular diseases, and neurodegenerative diseases. Stilbenoids are intensively metabolically transformed by colon microbiota, and their corresponding metabolites might show different or stronger biological activity than their parent molecules. The aim of the present study was to determine the metabolism of six stilbenoids (resveratrol, oxyresveratrol, piceatannol, thunalbene, batatasin III, and pinostilbene), mediated by colon microbiota. Stilbenoids were fermented in an in vitro faecal fermentation system using fresh faeces from five different donors as an inoculum.

Received: 3 June 2019; Accepted: 1 July 2019; Published: 15 July 2019 Abstract The very well-known bioactive natural product, resveratrol (3,5,4′-trihydroxystilbene), is a highly studied secondary metabolite produced by several plants, particularly grapes, passion fruit, white tea, and berries. It is in high demand not only because of its wide range of biological activities against various kinds of cardiovascular and nerve-related diseases, but also as important ingredients in pharmaceuticals and nutritional supplements. Due to its very low content in plants, multi-step isolation and purification processes, and environmental and chemical hazards issues, resveratrol extraction from plants is difficult, time consuming, impracticable, and unsustainable. Therefore, microbial hosts, such as Escherichia coli, Saccharomyces cerevisiae, and Corynebacterium glutamicum, are commonly used as an alternative production source by improvising resveratrol biosynthetic genes in them. The biosynthesis genes are rewired applying combinatorial biosynthetic systems, including metabolic engineering and synthetic biology, while optimizing the various production processes. The native biosynthesis of resveratrol is not present in microbes, which are easy to manipulate genetically, so the use of microbial hosts is increasing these days.

However, the role of AL in regulating inflammation has not been elucidated. Here we investigated the molecular mechanisms underlying the anti-inflammation of AL ethanolic extract in RAW 264.7 murine macrophage cell line. The HPLC results revealed that this plant was rich in oxyresveratrol, and AL ethanolic extract exhibited anti-inflammatory properties. In particular, AL extract decreased lipopolysaccharide (LPS)-mediated production and secretion of cytokines and chemokine, including IL-6, TNF-α, and MCP-1.

Abstract. Resveratrol, trans-3,5,4'-trihydroxystilbene, was first and cervical carcinoma. The growth-inhibitory effects of isolated in 1940 as a constituent of the roots of white hellebore resveratrol are mediated through cell-cycle arrest; up- (Veratrum grandiflorum O. Loes), but has since been found regulation of p21Cip1/WAF1, p53 and Bax; down-regulation of in various plants, including grapes, berries and peanuts. survivin, cyclin D1, cyclin E, Bcl-2, Bcl-xL and cIAPs; and Besides cardioprotective effects, resveratrol exhibits anticancer activation of caspases. Resveratrol has been shown to suppress properties, as suggested by its ability to suppress proliferation the activation of several transcription factors, including NF- of a wide variety of tumor cells, including lymphoid and Î B, AP-1 and Egr-1; to inhibit protein kinases including IÎ B· myeloid cancers; multiple myeloma; cancers of the breast, kinase, JNK, MAPK, Akt, PKC, PKD and casein kinase II; prostate, stomach, colon, pancreas, and thyroid; melanoma; and to down-regulate products of genes such as COX-2, head and neck squamous cell carcinoma; ovarian carcinoma; 5-LOX, VEGF, IL-1, IL-6, IL-8, AR and PSA.
