This volume examines the phytoalexin resveratrol and the ongoing studies about its effects on lifespan and health. Resveratrol (3,5,4'-trihydroxy-trans-stilbene), a phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi, significantly extends the lifespan of the yeast Saccharomyces cerevisiae,  Caenorhabditis elegans and the fruit fly Drosophila melanogaster. Resveratrol is currently a topic of numerous animal and human studies into its effects. The effects of resveratrol on the lifespan of many model organisms remain controversial. Anti-cancer, anti-inflammatory, blood-sugar-lowering, and other beneficial cardiovascular effects of resveratrol have been reported in experiments with mouse and rat model systems. However, most of these results have yet to be replicated in humans. Resveratrol is found in the skin of red grapes and is a constituent of red wine. Resveratrol has also been produced by chemical synthesis or by biotechnological synthesis and is sold as a nutritional supplement derived primarily from Japanese knotweed.NOTE: Annals volumes are available for sale as individual books or as a journal.

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a phenol phytoalexin derived from grapes, berries, and other plants  possessing a spectrum of pharmacologic properties.  Resveratrol has been shown to modulate LDL levels, a major risk factor for cardiovascular disease, to interfere with or inhibit oncogenesis and tumor proliferation in in vivo animal cancer models and in human tumor cells in vitro, to significantly extend the lifespan of the yeastSaccharomyces cerevisiae,  Caenorhabditis elegans and the fruit fly Drosophila melanogaster, and to produce wide-ranging benefits in animal models of obsesity and diabetes.Resveratrol has gained mainstream attention as “the red wine pill,” with widespread claims made of human health benefits that have outpaced the existing evidence. Over the past few years, many clinical trials have been conducted to evaluate the health effects of resveratrol in humans, in the treatment of cancer, cardiovascular disease, obesity, diabetes, osteopenia and osteoporosis, and others.  Considerable work is also underway exploring the optimization of resveratrol delivery and bioavailability in nutraceutical and pharmaceutical paradigms.
