SRT 2183 is a selective Sirtuin-1 (SIRT1) activator with an EC1.5 value of 0.36 μM[1]. SRT 2183 induces growth arrest and apoptosis, concomitant with deacetylation of STAT3 and NF-κB, and reduction of c-Myc protein levels[2].

SRT2183 is a small molecule activator of the sirtuin protein isoform SIRT1.

1-20 μM SRT2183 can effectively inhibit cell growth and apoptosis. It can cause increased mRNA levels of genes involved in pro-apoptosis, growth arrest, and DNA damage response. SRT1720, SRT2183, SRT1460 and resveratrol have multiple off-target effects on some receptors, enzymes, transporters and ion channels. They are not direct activators of SIRT1.
