Mice given the new drug, called SRT1720, gorged on high-fat food for 4 months without gaining weight or developing diabetes, and ran 2x as far on a treadmill as their control-group counterparts. The effects of the compound are similar to those of resveratrol, a molecule found in red wine that has previously been shown to extend life span and have health benefits in mice. But SRT1720 is 1000x more potent than resveratrol, meaning that it could be taken in smaller doses.
