    Biologists have found a class of chemicals that they hope will make people live longer by activating an ancient survival reflex. One of the chemicals, a natural substance known as resveratrol, is found in red wines, particularly those made in cooler climates like that of New York. The finding could help explain the so-called French paradox, the fact that the French live as long as anyone else despite consuming fatty foods deemed threatening to the heart. Besides the wine connection, the finding has the attraction of stemming from fundamental research in the biology of aging. However, the new chemicals have...

    BOSTON (Reuters) - Researchers have known for years that cutting calories can prolong life in everything from yeast cells to mammals. But an easier way to live longer may be as simple as turning a corkscrew. Molecules found in red wine, peanuts and other products of the plant world have for the first time been shown to mimic the life-extending effects of calorie restriction, a finding that could help researchers develop drugs that lengthen life and prevent or treat aging-related diseases. Researchers said on Sunday that one of the molecules, a compound known as resveratrol, was shown in a study...
  • Study: 'Anti-Aging' Antioxidant Actually Seems to Undo Effects of Exercise

    The Atlantic ^ | 08/13/2013 | JAMES HAMBLIN
    The compound resveratrol, believed to benefit longevity and heart health for its antioxidant properties, seemed to undermine the cardiovascular benefits of exercise in a small study. When some plants (like grape vines) are under stress, they produce a polyphenol known as resveratrol, which you may have heard of as the "anti-aging" chemical. Resveratrol has been shown to improve cardiovascular performance and extend the lives of non-mammals and mice -- specifically improving the lipid profiles and longevity of mice who ate a lot of fat. We believe that's because of its work as an antioxidant. The mice in that study got...
  • New drug being developed ... 'could help humans live until they are 150'

    The new drugs are synthetic versions of resveratrol which is found in red wine and is believed to have an anti-ageing effect as it boosts activity of a protein called SIRT1. Pharmaceutical giant GlaxoSmithKline has been testing the medications on patients suffering with medical conditions including cancer, diabetes and heart disease. The work proves that a single anti-ageing enzyme in the body can be targeted, with the potential to prevent age-related diseases and extend lifespans. The most common naturally-occurring activator is resveratrol, which is found in small quantities in red wine, but synthetic activators with much stronger activity are already...

    The drugs are synthetic versions of resveratrol, found in red wine, an organic chemical believed to have an anti-aging effect, by boosting activity of a protein called SIRT1. GSK, the pharmaceutical firm, is testing them on people with particular medical conditions, namely Type II diabetes and psoriasis, a serious skin condition. David Sinclair, professor of genetics at Harvard University, said aging might not actually be an "irreversible affliction". He said: “Now we are looking at whether there are benefits for those who are already healthy. "Things there are also looking promising. We're finding that aging isn't the irreversible affliction that...

    (Edmonton) Researchers in the Faculty of Medicine & Dentistry at the University of Alberta have discovered that resveratrol, a powerful antioxidant found in common foods, prevents a syndrome in some offspring that could lead to later health issues such as diabetes. Resveratrol is found in fruits, nuts and red wine, and has been shown to extend the lifespan of many species. Human offspring that have trouble growing in the womb have an increased risk of developing metabolic problems later in life. But U of A medical researchers Jason Dyck and Sandra Davidge and their teams found that administering resveratrol to...

    As strange as it sounds, a new research study published in the FASEB Journal (http://www.fasebj.org), suggests that the "healthy" ingredient in red wine, resveratrol, may prevent the negative effects that spaceflight and sedentary lifestyles have on people. The report describes experiments in rats that simulated the weightlessness of spaceflight, during which the group fed resveratrol did not develop insulin resistance or a loss of bone mineral density, as did those who were not fed resveratrol. This study also suggests that resveratrol may be able to prevent the deleterious consequences of sedentary behaviors in humans.

    US chemists have discovered how to selectively synthesise a wide range of natural polyphenol compounds based on resveratrol, a stilbenoid consisting of three phenols on two aromatic rings linked by a short hydrocarbon chain. Controlled synthesis of these compounds will allow researchers to probe their possible health benefits.Resveratrol and its many derivatives are present in the skin of grapes, for example, and are thought to be responsible for some of the apparent health benefits of red wine. These health benefits may help to explain the 'French paradox' - a low incidence of coronary heart disease in the population, despite a...

    The pharmaceutical company Sirtris announced last month that it had halted the last of its clinical trials of resveratrol, the minor ingredient of red wine that some researchers see as a drug that can extend life. The decision signifies an apparent divergence of views on the merits of resveratrol between the current head of the company, which was bought by GlaxoSmithKline in 2008 for $720 million, and its founders. George Vlasuk, Sirtris’s chief executive, said in an interview last week that SRT501, Sirtris’s formulation of resveratrol, “was not an important part of the acquisition of Sirtris by GSK.” Resveratrol has...

So, you can drink too much wine, or ingest too much resveratrol, but in an unprecedented study, heart researchers report they couldn't find a toxic dose for Longevinex®, a resveratrol-based dietary supplement. Investigators previously reported that six or more glasses of red wine per day actually increase the risk, whereas 3-5 glasses per day optimally reduce risk for cardiac death. This is the well-known J-shaped risk curve (risk goes down,...

    Resveratrol — found in red wine, grapes, blueberries, peanuts and other plants — stops out-of-control blood vessel growth in the eye, according to vision researchers at Washington University School of Medicine in St. Louis. The discovery has implications for preserving vision in blinding eye diseases such as diabetic retinopathy and age-related macular degeneration, the leading cause of blindness in Americans over 50. The formation of new blood vessels, called angiogenesis, also plays a key role in certain cancers and in atherosclerosis. Conducting experiments in mouse retinas, the researchers found that resveratrol can inhibit angiogenesis. Another surprise was the pathway through...

    In August 2003, when scientists first revealed the life-extending powers of trans-3,4,'5-trihydroxystilbene-- also known as resveratrol -- its earthly form had all the allure of an apple in the garden of Eden. Ruby red, delicately fragrant, shapely in a rounded nest of glass, red wine can deliver as much as 1.5 milligrams of the plant compound resveratrol per four-ounce serving. At concentrations present in a person's blood after two glasses of red wine, resveratrol has been found to suppress the formation of blood clots and boost the efficiency of immune system cells. Much larger doses of resveratrol increase the life...

    An ingredient of red wine really is a 'wonderdrug', claim scientists, after research suggested it kills cancer cells and protects the heart and brain from damage. Researchers claim moderate drinking of red wine appears to reduce "all causes of mortality" and protects people from age-related disorders such as dementia, diabetes and high blood pressure. They said that the key ingredient appears to be resveratrol which in small doses acts as an antioxidant protecting organs but in larger quantities kills dangerous cancer cells. "The breadth of benefits is remarkable – cancer prevention, protection of the heart and brain from damage, reducing...

    A new insight into the reason for aging has been gained by scientists trying to understand how resveratrol, a minor ingredient of red wine, improves the health and lifespan of laboratory mice. They believe that the integrity of chromosomes is compromised as people age, and that resveratrol works by activating a protein known as sirtuin that restores the chromosomes to health. The finding, published online Wednesday in the journal Cell, is from a group led by David Sinclair of the Harvard Medical School. It is part of a growing effort by biologists to understand the sirtuins and other powerful agents...
