By studying resveratrol, we also learned that it is possible to activate sirtuins with a chemical. This prompted a flood of research into other sirtuin-activating compounds, called STACs, that are many times more potent than resveratrol at stimulating the survival circuit and extending healthy lifespans in animals. They go by names such as SRT1720 and SRT2104, both of which extend the healthy lifespan of mice when given to them late in life.
