Found in red grapes and wine, resveratrol has been credited with extending life span in a variety of organisms.
Resveratrol mimics the life extending properties of caloric restriction by activating enzymes called sirtuins,
which influence a variety of aging -related metabolic functions.
Sirtris was found in 2004 after Dr.David Siclair of Harvard Medical School began publishing findings regarding
resveratrol 's remarkable potential benefits. Sirtris stated goal is to discover and develop small molecules
with anti aging potential, and its research efforts have largely focused on enhancing the potency of resveratrol-
based compounds.
Recently, pharmaceutical giant GlaxoSmith Kline announced that it would acquire all outstanding shares
of Sirtris pharmaceuticals for $ 750 million in order to cash in on the life extending promise of resveratrol
based compounds. GSK wants to create a Rx drug from resveratrol compounds in order to treat age related
disease. GSK hopes to modify the resveratrol molecule to further bolster its bioavailability and effects.
Such a modification would also allow the drug company to patent the new molecule and market it exclusively.
