Trihydroxy trans stilbene-

Resveratrol is a polyphenolic natural product that is present in red wine and peanuts and has inhibitory activity against inflammation, heart disease, and cancer. At least fold higher concentrations of compound were required to produce cytotoxicity against growing or stationary human embryonic lung fibroblasts. Mechanism of action studies determined that resveratrol blocked virus-induced activation of the epidermal growth factor receptor EGFR and phosphatidylinositolkinase signal transduction as well as NF-kappaB and Sp1 transcription factor activation shortly following infection. Resveratrol prevented the appearance of immediate-early, early, and late viral proteins. Human cytomegalovirus DNA replication was reduced to undetectable levels by treatment with resveratrol, as were the second late phases of virus-induced phosphatidylinositolkinase signaling and transcription factor activation.

The expression of apoptosis- or autophagy-associated proteins was measured using Western blotting. The formation of acidic compartments was detected using AO staining, neutral red staining and Lysotracker-Red staining.

LC3 punctae were analyzed with fluorescence microscopy. It inhibited the mTOR-dependent pathway, but did not impair autophagic flux. Access provided by.

Over half of these patients are not eligible for surgery at the time of diagnosis, and chemotherapy remains one of the most common therapies, even though it is associated with a range of side effects 3. The discovery and development of more potent compounds with fewer side effects for the treatment of NSCLC has become an increasingly active area of research. Natural products NPs are believed to be an important source of new chemical substances that can serve as potent therapeutics for various human cancers, including NSCLC 4.

The use of NPs as anti-tumor agents for the management of NSCLC is an attractive idea because they are readily available and exhibit little or no toxicity 4. Resveratrol 3,5,4-trihydroxy- trans -stilbene, RSV , a phytoalexin found in the skin of grapes, peanuts, mulberries, red wine, Polygonum cuspidatum Sieb et Zucc and many types of foods, is one such NP and has been shown to exhibit both anti-tumor and chemopreventive effects 5.

Previous studies have indicated that resveratrol functions not only as a chemoprotective agent in human NSCLC A cells but also has therapeutic effects against existing lung carcinoma 6 , 7. Although high doses of resveratrol can inhibit the proliferation of A cells by inducing apoptosis and autophagic cell death 8 , 9 , a major challenge for the use of this compound is that the concentration of resveratrol required to induce cancer cell death in vitro is too high to achieve in vivo in a clinical setting 10 , 11 , The structural modification of NPs is an efficient method to increase their activity and reduce the side effects.

A number of synthetic analogues of resveratrol have been developed in recent years, and some hydroxystilbenes with improved activity have been discovered. For example, 3,4,5-trihydroxy-trans-stilbene 3,4,5-THS has been shown to exhibit a potent cytotoxic effect on human leukemia Jurkat cells by inducing extensive cell apoptosis at lower concentrations than resveratrol The molecular formula of this compound is C 14 H 12 O 3 , and its molecular weight is PowerPoint slide.

A cells were plated in well cell culture plates. The cells were then treated with various compounds, as indicated in the legends to the figures. The cell viability was determined with an MTT assay as described previously AO moves freely across biological membranes and produces red fluorescence in acidic compartments and green fluorescence in the cytosolic and nuclear compartments.

After treatment, cells were stained with neutral red 0. The cells were then washed and observed with an inverted phase contrast microscope Nikon, Tokyo, Japan. The cells were then washed and observed by fluorescence microscopy Nikon, Tokyo, Japan.

Apoptotic cells were stained bright blue due to chromatin condensation. The percentage of fluorescently stained cells was calculated based on the images. A cells were observed by fluorescence microscopy Nikon, Japan. Cells were evaluated with a fluorescence microscope. A cell-free condition was used to determine the background fluorescence, and the relative fluorescence intensity in the control group was set to 1.

All experiments were performed in duplicate and repeated at least three times. B Cell viability determined by MTT assay. Annexin V-positive cells were considered to be in the early stage of apoptosis, whereas Annexin V and PI-positive cells were considered to be in the late stage of apoptosis. F Histogram shows the relative level of proteins.

To understand the nature of the vacuoles that were observed under phase-contrast microscopy, we first stained cells with AO. Similar results were obtained from the neutral red staining Figure 3B. D Histogram shows the ratio of apoptotic A cells. Nuclei were stained with Hoechst D Histogram shows the quantification of endogenous LC3 punctuate per cell. To discriminate between these two possibilities, we first evaluated the level of p62, which is involved in the formation of autophagosomes and constitutively degraded by the autophagic pathway via specific binding to LC3 Therefore, a decrease in the p62 level reflects unimpaired autophagic flux.

Both mTOR-dependent and -independent pathways can induce autophagy in cancer cells 20 , D Cell viability determined by the MTT assay. The histogram shows the relative fluorescent intensity of DCF. AO staining, neutral red staining, and Lysotracker-Red staining identified these vacuoles as acidic compartments Figure 3.

One of the classical pathways that controls autophagic activity is mTOR signaling However, further studies are needed to verify this hypothesis. Both apoptosis and autophagy are highly conserved processes that maintain organismal and cellular homeostasis, respectively. While apoptosis fulfills this role by removing damaged or unwanted cells, autophagy maintains cellular homeostasis by recycling selective intracellular organelles and proteins, and thus is considered an important protective mechanism for cancer cells in response to chemotherapy However, autophagy may help to induce apoptosis under certain conditions or lead to a non-apoptotic form of programmed cell death PCD called autophagic cell death or autophagy-associated cell death type II PCD Thus, the function of autophagy as cell death or cell survival machinery in different cases needs to be established.

Resveratrol could reportedly induce both apoptosis and autophagic cell death in A cells 9 , ROS, which are cytotoxic, often increase in concentration in cancer cells immediately after exposure to chemotherapeutic agents It is also well established that ROS play a central role in the induction of cell autophagy and apoptosis Autophagy can reportedly remove damaged mitochondria to limit ROS amplification The mitochondria pathway is a key signaling pathway in apoptosis induction the intrinsic cell death pathway.

However, this hypothesis needs to be addressed in more detail in our future study. However, several questions remain to be answered.

These questions will need to be addressed in more detail in our future studies. Cancer statistics CA Cancer J Clin ; 63 : 11— Management of non small cell lung cancer.

Trihydroxy trans stilbene. How does Resveratrol work?

It as an anti-inflammatory agent- Resveratrol has the ability to limit cyclooxygenase and lipoxygenase thereby controlling inflammation that can damage the cells. The cell transcription factors can also induce swelling and inflammation. It as an antioxidant- Through the nervous system and the liver, resveratrol can also reduce the amount of free radicals in the body.

It does this by inhibiting monoamine oxidase that steals electrons and destroys the nerve cells. By doing this, it works as one of the best antioxidants. Over the past few years, resveratrol powder has gained a lot of popularity due to its disease-fighting and anti-aging powers. While expert agrees that it works well, data is still lacking to confirm its effectiveness.

According to experts, it has a lot of health benefits such as protecting the circulatory system and the heart, protecting against clots, lowering cholesterol among others. Animal studies have also shown that it can help lower the blood sugar levels.

Some of its benefits include. However, it might interact with NSAID medications such as aspirin, ibuprofen and blood thinners that may lead to bleeding. Just like other supplements, FDA does not regulate it. It also does not have any specific dosage. This means the amount that you should take can vary from one time to another and from one supplement to another. Patients taking drugs such as warfarin, aspirin, and clopidogrel should inform their physicians that they are taking these drugs before being put on the supplements.

More so, they should always advise their health care providers of any over the counter medications or dietary supplements that they use. Those who suffer from blood disorders that cause bleeding should be monitored closely while taking the supplement. Those who are about to undergo surgery should also stop taking the drug two weeks before undergoing the procedure and only resume taking it two weeks after the surgery.

This is to reduce any chances of bleeding while taking the supplement. You should also avoid taking resveratrol powder or excessive amount of products containing it while breastfeeding or pregnant. Although no studies have been done to this effect, this drug should be avoided especially among children.

Since it has mild estrogenic activity, women suffering from cancer should seek medical advice before taking it. Although the supplement reduces enzyme activity, whether this is significant among humans is not yet known. If you want to take resveratrol, it is better take pharmaceutical grade resveratrol powder.

As compared to the amount that has been shown in research, the dosages in most supplements are usually lower. Most resveratrol supplements are grams and grams. To get the correct dosage you should consume at least 2 grams of the supplement daily. You can also supplement it with melatonin so as to provide you with a synergistic effect. Until more studies is done, experts are still reluctant to recommend resveratrol powder for disease prevention and anti-aging.

This is because they will advise if you may experience any side effects. Overall, it is still the best supplement that has a lot of benefits. Resveratrol Powder. Product Detail. In general, wines made from grapes of the Pinot noir and St. Laurent varieties showed the highest level of trans -resveratrol, though no wine or region can yet be said to produce wines with significantly higher concentrations than any other wine or region. Red wine contains between 0. White wine has much less because red wine is fermented with the skins, allowing the wine to extract the resveratrol, whereas white wine is fermented after the skin has been removed.

Mulberries especially the skin are a source of as much as 50 micrograms of resveratrol per gram dry weight. Sales of resveratrol supplements increased in after studies on non-humans. Harvard University scientist and professor David Sinclair co-founded Sirtris Pharmaceuticals , the initial product of which was a resveratrol formulation; [49] Sinclair became known for making statements about resveratrol such as: " It's as close to a miraculous molecule as you can find One hundred years from now, people will maybe be taking these molecules on a daily basis to prevent heart disease, stroke, and cancer.

Sinclair and others obtained significant news coverage about resveratrol. The first mention of resveratrol was in a Japanese article in by Michio Takaoka, who isolated it from Veratrum album , variety grandiflorum , and later, in , from the roots of Japanese knotweed.

As of , the extensive research on resveratrol in numerous laboratory models of human diseases — conducted over decades — has failed to show any anti-disease effect in randomized controlled trials on humans. As of [update] , the results of studies on laboratory animals or human clinical trials concerning the effects of resveratrol on cancer are inconsistent, [15] even if massive doses of resveratrol are used. Resveratrol is under preliminary research for its potential to limit secondary damage after ischemic stroke or acute brain trauma , [61] and its possible effect on cognition.

One review found little evidence for use of resveratrol to treat diabetes. Despite considerable in vitro and animal research, there is no evidence that resveratrol taken orally or topically has any effect on human skin. From Wikipedia, the free encyclopedia.

Purpose: Chronic hepatitis C is a pathological state in which oxidative stress is enhanced and it has been said that antioxidant therapy may have a role in slowing progression to cirrhosis.

Resveratrol RVT is a polyphenolic natural product contained in red wine and is known as an antioxidant that inhibits inflammation, heart disease and cancer. The most significant effect of RVT is to extend lifespan especially in animals and recently it has been widely investigated.

There are many papers reporting that RVT inhibits replication of various DNA or RNA viruses, such as human cytomegalovirus, varicella-zoster virus, influenza A virus and herpes simplex virus. Methods: We used a replicon system which includes the luciferase reporter gene OR6 cell. In microarray analysis, there are many genes altered more than 1.

Ten pathways were significantly decreased in RVT-treated cells such as a cell-cycle, fatty acid oxidation, inflammatory response pathway and glycogen metabolism, and 1 pathway was increased. There were several pathways coincided between RVT- and VEtreated cells, but different pathways were also determined. It is suggested that further investigation of this mechanisms and different between antioxidants may serve a clue for the regulation.
