2-[(2-Hydroxynaphthalen-1-ylmethylene)amino]-N-(1-phenethyl)benzamide Sir Two Inhibitor Naphthol Yellow solid. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. 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). Purity: ≥97% by HPLC. Ref.: Mai, A., et al. 2005. J. Med. Chem. 48, 7789. Grozinger, C.M., et al. 2001. J. Biol. Chem. 276, 38837. |
