SRT-1720, also known as CAY10559 and 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 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% .
SRT1720 is an experimental drug that was studied by Sirtris Pharmaceuticals intended as a small-molecule activator of the sirtuinsubtype SIRT1. The compound has been studied in animals, but safety and efficacy in humans have not been established.
Animal research
In animal models of obesity and diabetes SRT1720 was found to improve insulin sensitivity and lower plasma glucose levels in fat, muscle and liver tissue, and increase mitochondrial and metabolic function.[1] In mice rendered obese and diabetic by feeding a high-fat, high-sugar diet, a study performed at the National Institute of Aging found that feeding chow infused with the highest dose of SRT1720 beginning at one year of age increased mean lifespan by 18%, and maximum lifespan by 5%, as compared to other short-lived obese, diabetic mice; however, treated animals still lived substantially shorter lives than normal-weight mice fed normal chow with no drug.[2] In a later study, SRT1720 increased mean lifespan of obese, diabetic mice by 21.7%, similar to the earlier study, but there was no effect on maximum lifespan in this study.[3] In normal-weight mice fed a standard rodent diet, SRT1720 increased mean lifespan by just 8.8%, and again had no effect on maximum lifespan.[3]
Since the discovery of SRT1720, the claim that this compound is a SIRT1 activator has been questioned[4][5][6] and further defended.[7][8]
Although SRT1720 is not currently undergoing clinical development, a related compound, SRT2104, is currently in clinical development for metabolic diseases.[9]

A series of imidazo[1,2-b]thiazole derivatives is shown to activate the NAD+-dependent deacetylase SIRT1, a potential new therapeutic target to treat various metabolic disorders. This series of compounds was derived from a high throughput screening hit bearing an oxazolopyridine core. Water-solubilizing groups could be installed conveniently at either the C-2 or C-3 position of the imidazo[1,2-b]thiazole ring. The SIRT1 enzyme activity could be adjusted by modifying the amide portion of these imidazo[1,2-b]thiazole derivatives. The most potent analogue within this series, namely, compound 29, has demonstrated oral antidiabetic activity in the ob/ob mouse model, the diet-induced obesity (DIO) mouse model, and the Zucker fa/fa rat model.
