SRT1720 is a drug developed by Sirtris Pharmaceuticals intended as a small-molecule activator of the sirtuin subtype SIRT1. It has similar activity in the body to the known SIRT1 activator resveratrol, but is 1000x more potent [. In animal studies it was found to improve ] citation needed insulin sensitivity and lower plasma glucose levels in fat, muscle and liver tissue, and increased mitochondrial and metabolic function. A study of SRT1720 conducted by the National Institute on Aging found that the drug may extend the lifespan of obese mice by 44%. [1 ] Although SRT1720 is not currently undergoing clinical development, a related compound, [2 ] SRT2104, is currently in clinical development for metabolic diseases. [3 ]
Since the discovery of SRT1720, the claim that this compound is a SIRT1 activator has been questioned
[4 ] [5 ] and further defended. [6 ] [7 ] [8 ]
