Information SRT2183 is a small-molecule activator of the sirtuin subtypeSIRT1, currently being developed by Sirtris Pharmaceuticals. Targets SIRT1 In vitro SRT2183 is potent with growth arrest and apoptosis induced at doses ranging from 1-20 μM. SRT2183 treatment leads to increased mRNA levels of pro-apoptosis, growth arrest, and DNA damage response genes. SRT1720, SRT2183, SRT1460, and resveratrol exhibit multiple off-target activities against receptors, enzymes, transporters, and ion channels. They are not direct activators of SIRT1. SRT2183 has little or no effect on SIRT1 deacetylating activity with native full-length substrates. SRT2183 activates AMPK, increases Sirt1 expression and decreases RelA/p65 lysine310 acetylation, critical for NF-κB activation, and an established Sirt1 target and inhibits RANKL-induced osteoclast generation and resorptive capacity in bone marrow macrophages.
