0.4mg/ml Taking the 1 mL working solution as an example, add 20 μL of 20 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 630 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Sirtinol is a specific SIRT1 and SIRT2 inhibitor with IC50 of 131 μM and 38 μM in cell-free assays, respectively.
in vitro 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. [1] 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. [3] Inhibition of Sirt1 by Sirtinol enhances UV- and H2O2-induced p53 acetylation to enhance cell death in cultured skin keratinocytes. [6] 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. [7]
in vivo 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. [4]
特徴 Sirtinol does not inhibit class I and class II HDACs.

プロトコル(参考用のみ)

キナーゼアッセイ Inhibition in vitro of human Sirt2 activity
1.5 μg of recombinant human GST-Sirt2 (amino acids 18-340) are incubated at 30°C for 2 hours in 50 μL of assay buffer (50 mM Tris-HCl, pH 8.8, 4 mM MgCl2, 0.2 mM dithiothreitol with different concentrations of Sirtinol, 50 μM NAD, and tritiated acetylated HeLa histones (1000 cpm), purified by acid extraction. HDAC activity is determined by scintillation counting of the ethyl acetate-soluble [3H]acetic acid.
細胞アッセイ 細胞株 LNCaP, 22Rv1, DU145, and PC3
濃度 Dissolved in DMSO, final concentrations ~120 μM
反応時間 24 or 48 hours
実験の流れ

Cells are grown to 60% confluence and then treated with 30 μM or 120 μM sirtinol for 24 or 48 hours. Cells are trypsinized and collected. The cells are pelleted by centrifugation and resuspended in PBS (120 μL). Trypan blue (0.4% in PBS; 10 μL) is added to a smaller aliquot (10 μL) of cell suspension, and the number of cells (viable unstained and nonviable blue) are counted.
動物実験 動物モデル Male Sprague-Dawley rats subjected to trauma-hemorrhage
投薬量 1 mg/kg
投与方法 Administered intravenously
