Sirtinol is a SIRT inhibitor. Sirtinol significantly increased the acetylation of p53, which has been reported to be a target of SIRT1/2. Sirtinol significantly increased the G1 phase of the cell cycle.

How to use

In Vitro:

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. 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.

In Vivo:

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