SIRT-IN-3 is a potent SIRT inhibitor, with an IC 50 of 17 μM for SIRT1. SIRT-IN-3 shows about 4-fold and 14-fold selectivity for SIRT1 over SIRT2 and SIRT3 , respectively (IC 50 of 74 μM and 235 μM for SIRT2 and SIRT3 , respectively).
In Vitro
SIRT-IN-3 (Compound 7) (30-300 μM; 8 hours) causes p53 acetylation in in HCT116 cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
