Sirtinol is a cell-permeable, specific inhibitor of sirtuin NAD-dependant histone deacetylases.

溶解性：DMSO : 39.5 mg/mL (100 mM)

体外研究：

Sirtinol potently inhibits recombinant yeast Sir2p activity in vitro with IC50 of 68 μM. Unlike TSA, Sirtinol has shown no effect on human HDAC1, indicating that it is a selective sirtuin inhibitor. Unlike TSA, treatment of human primary fibroblasts with Sirtinol does not cause global changes in acetylation of histones and tubulin, nor does it induce a morphological change in the HeLa tumor cell line. Sirtinol treatment at 100 μM for 24 hours causes a sustained growth arrest in MCF-7 and H1299 cells for up to 9 days after Sirtinol withdrawal. Sirtinol treatment induces increased SA-β-gal activity and expression of PAI-1 in both MCF-7 and H1299 cells, more potently than Splitomicin. Sirtinol inhibits colony formation at concentrations of 33 μM and higher in MCF-7 and H1299 cells, more effectively compared with Splitomicin. Sirtinol treatment (100 μM) significantly attenuates both basal and EGF- or IGF-I-stimulated phosphorylation of ERK, JNK/SAPK and p38 MAPK in MCF-7 and H1299 cells. Sirtinol blocks the basal and EGF-stimulated activation of Ras. Consistent, basal and EGF- or IGF-I-stimulated phosphorylation of Raf-1, MEK, SEK1/MKK4 and MKK7 is attenuated in Sirtinol-treated cells. Inhibition of Sirt1 by Sirtinol enhances UV- and H2O2-induced p53 acetylation to enhance cell death in cultured skin keratinocytes. Blocking of Sirt1 by Sirtinol treatment results in a significant inhibition in the growth and viability of human PCa cells while having no effect on normal prostate epithelial cells.

体内研究：Administration of Sirtinol at 1 mg/kg attenuates pro-inflammatory cytokine production and protects against hepatic injury following trauma-hemorrhage in male Sprague-Dawley rats.
