使用

A selective inhibitor of SIRT1 over SIRT2 and SIRT3

一般的な説明

A cell-permeable indole compound that acts as a potent and highly selective inhibitor of SIRT1 (IC₅₀ = 98 nM). It inhibits other sirtuin family deacetylases only at much higher concentrations (IC₅₀ = 19.6 and 48.7 μM for SIRT2 and SIRT3, respectively) and shows no inhibitory effect against class I and II HDACs or NAD glycohydrolase even at concentrations as high as 100 μM. Shown to be orally bioavailable with a serum half-life of 136 minutes in mice in vivo.

生物活性

Selective inhibitor of SIRT1 that does not inhibit histone deacetylase (HDAC) or other sirtuin deacetylase family members (IC 50 values are 98, 19600, 48700, > 100000 and > 100000 nM for SIRT1, SIRT2, SIRT3, HDAC and NADase respectively). Enhances p53 acetylation in response to DNA damaging agents.
