Resveratrol, also known as trans-Resveratrol, SRT-501 and RM-1812, is a naturally occuring phytoalexin produced by several plants with anti-cancer, antioxidant, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects. Resveratrol induces phase II drug-metabolizing enzymes and induces promyelocytic leukemia cell differentiation, thereby exhibiting activities in three major steps of carcinogenesis. This agent may inhibit TNF-induced activation of NF-kappaB in a dose- and time-dependent manner.

ln Vitro |
Resveratrol (trans-Resveratrol; SRT501) is one of numerous polyphenolic chemicals found in a range of plant sources. In the vast majority of cases, Resveratrol demonstrates inhibitory/activating effects in the micromolar range, which may be pharmacologically feasible, although targets in the nanomolar range have also been described [1]. MCF-7 cells were plated in DME-F12 media supplemented with 5% FBS and increasing doses of Resveratrol. Control cells were treated with the same volume of vehicle (0.1% ethanol) alone. Resveratrol suppresses the development of MCF-7 cells in a dose-dependent way. Addition of 10 μM Resveratrol resulted in 82% suppression of MCF-7 cell growth after 6 days, but at 1 μM, only 10% inhibition was seen. Cells treated with 10 μM Resveratrol had a doubling time of 60 hours, whereas control cells doubled every 30 hours. Trypan blue exclusion assay demonstrated that at concentrations of 10 μM or below, Resveratrol did not impair cell viability (90% of viable cells), however at a dose of 100 μM, only 50% of cells survived after 6 days of Resveratrol administration. In addition, MCF-7 cells did not undergo apoptosis after incubation with Resveratrol at a dosage of 10 μM, as assessed by the ApoAlert Annexin V Apoptosis Kit [2]. Resveratrol promotes nitric oxide (NO) production in endothelial cells by upregulating the expression of endothelial nitric oxide synthase (eNOS), boosting eNOS enzyme activity, and blocking eNOS uncoupling [7].

ln Vivo |
In vivo, resveratrol has been shown to increase plasma antioxidant capacity and decrease lipid peroxidation; however, it is difficult to assess whether these effects are direct, or the result of upregulating endogenous antioxidant enzymes.[1]
Although most in vivo studies strongly support a chemopreventive effect of resveratrol, there are notable exceptions in which no benefit has been observed. For example, administration of 1–5 mg per kg (body weight) daily of resveratrol failed to affect the growth or metastasis of breast cancer in mice, despite promising in vitro results17. Dosage, delivery method, tumour origin and other components of the diet could all contribute to the efficacy of resveratrol treatment. Overall, in vivo studies clearly show great promise for this molecule in the treatment of cancers. Several Phase I clinical trials are currently underway for oral resveratrol in humans at doses as high as 7.5 g per day, including National Cancer Institute-sponsored studies at the University of Michigan, USA, and the University of Leicester.[1] In vivo, resveratrol has been shown to increase expression of both endothelial and inducible nitric oxide synthase (eNOS and iNOS, respectively).[1] Because resveratrol is an effective inhibitor of cyclooxygenase activity in vivo20,22,28, its anti-inflammatory properties have been investigated. [1] Treatment with resveratrol (trans-Resveratrol; SRT501) at 50 mg/kg (195.5±124.8 mm3; P<0.05) or 100 mg/kg reduced the mean tumor volume (81.7±70.5 mm3; P<0.001). Tumor mass and volume have a strong correlation. |

Enzyme Assay |
Insulin-like Growth Factor 1 Enzyme-Linked Immunosorbent Assay[2]
The concentration of IGF-1 in the cell supernatant was measured using Human IGF-I/IGF-1 DuoSet ELISA. For the measurement, microglia (HMC3) were seeded in 6-well plates (80,000 cells/1 mL medium/well) and treated with resveratrol (100 µM) for 24 h. Afterwards, cell supernatants were collected and processed according to manufacturer instructions. Glucose Uptake Quantification[2] For analysis of glucose uptake, microglia (HMC3) were seeded in white 96-well plates (5000 cells/100 µL medium/well). Upon 24 h of resveratrol (100 µM) treatment, glucose uptake from the medium was measured in technical duplicates using the non-radioactive Glucose Uptake-Glo™ Assay according to the manufacturer’s instructions. Plates were read using the TECAN GENios microplate reader. TMRE-Mitochondrial Membrane Potential Assay[2] Mitochondrial activity was investigated using the TMRE-Mitochondrial Membrane Potential Assay Kit according to manufacturer’s instructions. Microglia (HMC3) were seeded in 24-well plates (7500 cells/250 µL medium/well). Imaging was carried out upon the 24 h resveratrol (100 µM) treatment using the Keyence BZx800 Fluorescence Microscope. The fluorescence intensity of two areas from each experiment was quantified using ImageJ |

Inflammasome Activity Assays[2]
For the quantification of inflammasome activity, microglia (HMC3) were seeded in white 96-well plates (8000 cells/100 µL medium/well). Upon 6 h of resveratrol (100 µM) treatment, inflammasome activity was measured in technical duplicates using the Caspase-Glo® 1 Inflammasome Assay according to the manufacturer’s instructions. Plates were read using the TECAN GENios microplate reader. Scanning Electron Microscopy (SEM)[2] Microglia (HMC3) were seeded on 24 mm × 12 mm coverslips that were placed in 6-well plates (60,000 cells/1 mL medium/well). After 24 h resveratrol (100 µM) treatment cells were washed with PBS and fixed for 30 min in 3% glutaraldehyde. In the next step, samples were washed with PBS and kept in a 2% osmium solution for 20 min. Subsequently, all water was removed by placing samples in increasing ethanol concentrations (30–100%), and critical point drying was carried out using a CPD 030. Finally, samples were coated with an SCD 050 sputter coater for 50 s and imaged using a JSM-IT200. Proliferation[2] Proliferation was determined by counting the microglia (HMC3) seeded in 6-well plates (80,000 cells/1 mL medium/well) using the T20 Automated Cell Counter after 24 h of resveratrol (100 µM) treatment. Proliferation was calculated as an n-fold amount of the initially seeded cell number. |

This study ... examined the absorption, bioavailability, and metabolism of (14)C-resveratrol after oral and iv doses in six human volunteers. The absorption of a dietary relevant 25-mg oral dose was at least 70%, with peak plasma levels of resveratrol and metabolites of 491 + or - 90 ng/mL (about 2 uM) and a plasma half-life of 9.2 + or - 0.6 hr. However, only trace amounts of unchanged resveratrol (<5 ng/mL) could be detected in plasma. Most of the oral dose was recovered in urine, and liquid chromatography/mass spectrometry analysis identified three metabolic pathways, ie, sulfate and glucuronic acid conjugation of the phenolic groups and, interestingly, hydrogenation of the aliphatic double bond, the latter likely produced by the intestinal microflora. Extremely rapid sulfate conjugation by the intestine/liver appears to be the rate-limiting step in resveratrol's bioavailability. In plants, it mostly exists in glycosylated piceid forms (3-O-B-D-glucosides). Other minor conjugated forms containing 1 to 2 methyl groups (pterostilbene), a sulfate group (trans-resveratrol-3-sulfate) or a fatty acid have also been identified. Glycosylation is known to protect resveratrol from oxidative degradation, and glycosylated resveratrol is more stable ...

Toxicity/Toxicokinetics |
Hepatotoxicity
Liver injury attributable to resveratrol has not been reported. In trials of resveratrol in human subjects, there have been no reports of serum enzyme elevations or clinically apparent liver injury. Thus, hepatotoxicity due to resveratrol must be rare, if it occurs at all. Likelihood score: E (unlikely cause of clinically apparent liver injury). Drug Class: Herbal and Dietary Supplements Effects During Pregnancy and Lactation ◉ Summary of Use during Lactation Resveratrol (3,4',5-trans-trihydroxystilbene) is an antioxidant found in numerous plant species and in red wine. Resveratrol has no specific lactation-related uses. In general, it is used to prevent heart disease, cancer, and other diseases associated with aging, although high-quality studies are lacking. Resveratrol appears to be relatively free from adverse reactions. However, no data exist on the excretion of resveratrol into breastmilk or on the safety and efficacy of resveratrol in nursing mothers or infants. Resveratrol supplements usually contain hundreds of times the amounts found in wine or other foods, so their safety during breastfeeding cannot be assured. It is probably best to avoid the use of red wine as a source of resveratrol during breastfeeding. Refer to the LactMed record on Alcohol for details. Dietary supplements do not require extensive pre-marketing approval from the U.S. Food and Drug Administration. Manufacturers are responsible to ensure the safety, but do not need to prove the safety and effectiveness of dietary supplements before they are marketed. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does not certify the safety or effectiveness of a product. Because of the above issues, clinical testing results on one product may not be applicable to other products. More detailed information about dietary supplements is available elsewhere on the LactMed Web site. ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date.

Therapeutic Uses
Anti-Inflammatory Agents, Non-Steroidal; Anticarcinogenic Agents; Antimutagenic Agents; Antineoplastic Agents, Phytogenic; Antioxidants; Enzyme Inhibitors; Platelet Aggregation Inhibitors /EXPL THER/ The antioxidant potency of three natural polyphenols, resveratrol, curcumin, and genistein, was compared by using the two human models: oxymodified with H2O2 and homocysteine (Hcy) G proteins in the postmortem frontal cortex (FC) membranes of age-matched control and Alzheimer's disease (AD) subjects; and Cu(2+)-induced oxidation of plasma low-density lipoproteins (LDL). In Co, 3-10 uM polyphenols dose-dependently depressed the G protein 25% stimulation induced by 10 uM H2O2 or 500 uM Hcy. Resveratrol revealed significantly higher antioxidativity than curcumin or genistein. In AD, the antioxidativity of polyphenols showed no significant differences. Polyphenols (1 uM) significantly increased the LDL oxidation lag time (oxyresistance) as compared with control, the effect of resveratrol being most potent. Due to the dual antioxidant mechanism, the investigated polyphenols, particularly resveratrol, should have preferences for the preventive-therapeutic use in age-related oxidative stress-based pathologies. /EXPL THER/ Arthritis, an inflammation of the joints, is usually a chronic disease that results from dysregulation of pro-inflammatory cytokines (e.g. tumor necrosis factor and interleukin-1beta) and pro-inflammatory enzymes that mediate the production of prostaglandins (e.g. cyclooxygenase-2) and leukotrienes (e.g. lipooxygenase), together with the expression of adhesion molecules and matrix metalloproteinases, and hyperproliferation of synovial fibroblasts. All of these factors are regulated by the activation of the transcription factor nuclear factor-kappaB. Thus, agents that suppress the expression of tumor necrosis factor-alpha, interleukin-1beta, cyclooxygenase-2, lipooxygenase, matrix metalloproteinases or adhesion molecules, or suppress the activation of NF-kappaB, all have potential for the treatment of arthritis. Numerous agents derived from plants can suppress these cell signaling intermediates, including curcumin (from turmeric), resveratrol (red grapes, cranberries and peanuts), tea polyphenols, genistein (soy), quercetin (onions), silymarin (artichoke), guggulsterone (guggul), boswellic acid (salai guggul) and withanolides (ashwagandha). Indeed, several preclinical and clinical studies suggest that these agents have potential for arthritis treatment. Although gold compounds are no longer employed for the treatment of arthritis, the large number of inexpensive natural products that can modulate inflammatory responses, but lack side effects, constitute 'goldmines' for the treatment of arthritis. /EXPL THER/ Resveratrol, a red wine polyphenol, is known to protect against cardiovascular diseases and cancers, as well as to promote antiaging effects in numerous organisms. It also modulates pathomechanisms of debilitating neurological disorders, such as strokes, ischemia, and Huntington's disease. The role of resveratrol in Alzheimer's disease is still unclear, although some recent studies on red wine bioactive compounds suggest that resveratrol modulates multiple mechanisms of Alzheimer's disease pathology ... For more Therapeutic Uses (Complete) data for RESVERATROL (12 total), please visit the HSDB record page. Drug Warnings Pregnant women and nursing mothers should avoid the use of resveratrol-containing supplements. They should also avoid the use of wine as a resveratrol source. Purple grape juice is a good and safe source of resveratrol, as well as other polyphenolic antioxidants. Resveratrol is contraindicated in those hypersensitive to any component of resveratrol-containing product. Pharmacodynamics Resveratrol, a phytoalexin, has been found to inhibit herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) replication in a dose-dependent, reversible manner, although this is only one of its many pharmaceutical properties. In some countries where there is higher consumption of red wine, there appears to be a lower incidence of heart disease. Other benefits of resveratrol include its anti-inflammatory and antioxidant effects. In preclinical studies, Resveratrol has been found to have potential anticancer properties. |
