SIRT1/2/3 pan Inhibitor

A thienopyrimidinylcarboxamide that acts as a highly potent, reversible pan sirtuin (SIRT) inhibitor (IC₅₀ = 15, 10, and 33 nM for SIRT1, 2, and 3, respectively). Shown to bind to the SIRT catalytic site and occupy both the nicotinamide C-pocket and acetyl lysine substrate channel. Exhibits high selectivity over a panel of protein kinases, nuclelar receptors, GPCRs, and ion-channels (IC₅₀ >10 µM). Poorly affects hERG and cytochrome P450s (>50 µM). Exhibits desirable stability in microsomal preparations (human CL_int = 15.8 µL/min/mg, mouse CL_int = 12.7 µL/min/mg) and high solubility (297 µM), and low LogD (2.73).
