Solubility of SRT 1720 Hydrochloride
| Solvent | Dissolution Behavior | Temperature Effect | pH Effect |
|---|---|---|---|
| Water | Practically insoluble (very poor solubility) | Solubility slightly improves with increased temperature, but remains very low | Still poorly soluble under acidic or neutral conditions; alkaline conditions may slightly enhance solubility (due to phenolic hydroxyl groups), but compound stability is compromised |
| Dimethyl sulfoxide (DMSO) | Highly soluble; commonly used as a stock solution solvent | Dissolves rapidly with increasing temperature; typically fully dissolves at room temperature | Essentially unaffected by pH; suitable for preparing high-concentration stock solutions |
| Ethanol | Slightly soluble to soluble (concentration-dependent) | Heating significantly increases solubility | Stable under weakly acidic or neutral conditions; may degrade under strongly acidic or basic conditions |
| Methanol | Soluble | Increased temperature enhances dissolution | Similar to ethanol; may decompose under extreme pH conditions |
| Acetone | Soluble | Dissolves quickly; effect of heating is evident | Unaffected by pH, but may be unstable upon long-term storage |
| Chloroform | Soluble | Dissolves well at room temperature | Minimal influence from pH; suitable for extraction applications |
| Ethyl acetate | Moderately soluble | Higher temperatures aid dissolution | Little pH sensitivity; commonly used in organic-phase extractions |
Key Milestone of SRT 1720 Hydrochloride
| Year | Milestone | Description |
|---|---|---|
| 2008 | First Report & Discovery | Researchers at Sirtris Pharmaceuticals (a GSK subsidiary) first reported SRT1720 in Nature as a small-molecule activator of SIRT1 (sirtuin 1 deacetylase) with greater potency and selectivity than resveratrol. |
| 2009–2010 | Expanded Preclinical Studies | Numerous animal studies showed that SRT1720 improved insulin sensitivity, lowered blood glucose, and extended healthspan in models of obesity, type 2 diabetes, and metabolic syndrome. |
| 2010 | GSK Halts Development | GlaxoSmithKline suspended clinical development of the Sirtris compounds, including SRT1720, citing toxicological findings (e.g., potential hepatotoxicity), pharmacokinetic issues, and scientific debate over the mechanism of SIRT1 activation. |
| 2011–2013 | Mechanistic Controversy & Academic Research | Several independent groups questioned whether SRT1720 directly activates SIRT1, noting that its activity appeared to depend on fluorogenic substrates (e.g., Fluor de Lys) and was unclear on physiological substrates; other studies still supported its in vivo metabolic benefits. |
| 2013 | Independent Validation Published | A multi-center study led by the U.S. National Institute on Aging (NIA) and published in Science showed that SRT1720 improved metabolic health in high-fat-diet mice but did not significantly extend lifespan. |
| 2014–2018 | Ongoing Academic Exploration | Despite never entering the clinic, SRT1720 became a widely used tool compound for probing SIRT1 function in aging, inflammation, neurodegeneration, and cancer. |
| 2019–Present | Widespread Use as Research Tool | SRT1720 is now a standard chemical probe in aging and metabolism research, advancing understanding of the sirtuin family and informing the design of next-generation SIRT1 activators. |
