Why Sirtris Feels So Frisky

摘要

For folks worried about getting older, Sirtris Pharmaceuticals (SIRT) may provide some comfort. It is developing drugs that could slow aging by activating SIRTl, one member of a newly discovered class of enzymes called sirtuins that control the aging process. CEO and co-founder Christoph Westphal says resveratrol, a natural substance in red wine and other plant products, activates SIRTi, resulting in calorie restriction without needing to cut normal caloric intake, which extended test animals' lives. Sirtris has many patents on the formulation of resveratrol.
