Description

General description

A cell-permeable 2-hydroxy-1-naphthaldehyde derivative that acts as a specific and direct inhibitor of the sirtuin class of deacetylase activity with no affect on human HDAC1 (IC₅₀ = 48 µM, 131 µM and 58 µM for ySir2, hSIRT1 and hSIRT2, respectively). Reported to inhibit Sir2p transcriptional silencing activity in vivo (IC₅₀ = 25 µM), and NAD-dependent histone deacetylase activity of purified recombinant yeast Sir2p and human SIRT2 in vitro (IC₅₀ = 70 µM and 40 µM, respectively). A 10 mM (1 mg/254 µl) solution of Sirtinol (Cat. No. 566321) in DMSO is also available.

A cell-permeable 2-hydroxy-1-napthaldehyde derivative that acts as a specific and a direct inhibitor of sirtuin class of histone deacetylase (HDAC) activity. Does not affect human HDAC1. Reported to block Sir2p transcriptional silencing activity in vivo (IC₅₀ = 25 µM) and NAD-dependent HDAC activity in purified recombinant yeast Sir2p and human SIRT2 in vitro (IC₅₀ = 68 µM and 38 µM, respectively).
