AGK7 is an inactive control of AGK2, a cell-permeable and selective SIRT2 inhibitor [1][2].

The sirtuins are members of the histone deacetylase family of proteins that participate in many cellular functions and play an important role in aging. Silent information regulator 2 (Sir2) is a nicotinamide adenine dinucleotide-dependent histone deacetylase (HDAC) in yeast that participates in cell protection and cell cycle regulation. Human SIRT2 is involved in cell cycle regulation through the deacetylation ofα-tubulin [1].

AGK7 is an inactive control of AGK2 to be used in experiments with AGK2. AGK2 is a cell-permeable, potent and selective SIRT2 inhibitor with IC50 value of 3.5 μM. AGK2 slightly inhibited SIRT1 and 3 only at concentrations over 40 μM. Relative to an inactive control AGK7, AGK2 increased acetylated tubulin. In H4 cells transfected with α-Syn, AGK2 reduced α-Syn-mediated toxicity in a dose-dependent way. By contrast, the inactive AGK7 had no effect. In H4 cells cotransfected withα-Syn and synphilin-1, the inactive AGK7 failed to affect a-Syn aggregation, whereas AGK2 promoted the formation of enlarged inclusions [1].
