Sirtinol is a sirtuin (SIRT) inhibitor, with IC₅₀s of 48 μM, 57.7 μM and 131 μM for ySir2, hSIRT2 and hSIRT2, respectively^[1][2][3][4].

Sirtinol reduces the growth of MCF-7 cells in a concentration- and time-dependent manner. The IC₅₀ values of sirtinol are 48.6 μM and 43.5 μM after 24 and 48 h of treatment, respectively. Sirtinol significantly decreases SIRT1 expression and increases the acetylated p53 level^[1]. Sirtinol attenuates the proliferation and induces apoptosis of nonsmall cell lung cancer (NSCLC) H1299 cells and causes the significantly increased level of FoxO3a, a proapoptotic transcription factor targeted by Sirt1^[2].

Sirtinol has anti-inflammatory effects through direct inhibition of HNE activity and attenuates HNE-induced and LPS-mediated tissue or organ injury^[3].

Sirtinol is dissolved in 100% DMSO at concentration of 10 mM and stored at −20°C until use. The cell proliferation of H1299 cells is determined by trypan blue dye exclusion assay. Human nonsmall cell lung cancer (NSCLC) cells are seeded in 12-well plates and treated with indicated concentrations of sirtinol (0, 10, 20, and 50 μM) for 24 h and 48 h, respectively. After incubation, the cells are stained by 0.2% trypan blue and counted by Countess^[2].

Mice: 30 male mice (20–25 g, 7–8 weeks old) are used in this model. Briefly, mice are randomly divided into five groups; then mice are intraperitoneally injected with 50 μL DMSO (vehicle group) or sirtinol (2.5 or 5.0 mg/kg body weight). After 1 h, paw inflammation is induced . The thickness of the paw is measured before and after HNE or saline injection^[3].
