Thieno[3,2-d]pyriMidine-6-carboxaMide, 4-[4-[2-[(Methylsulfonyl)aMino]ethyl]-1-piperidinyl]-

SIRT-IN-2 is a potent inhibitor of SIRT1/2/3, with IC50s of 4, 4, 7 μM, respectively.

SIRT-IN-2 (compound 31) is one of the most potent truncated pan SIRT1/ 2/3 inhibitor, the IC50 values are 4, 4, 7 μM, respectively. SIRT-IN-2 (SIRT1/2/3 pan inhibitor) binds identically in the catalytic active site (RMS=0.29 ?), occupying the nicotinamide C-pocket and acetyl lysine substrate channel[1].
