SIRT2 Inhibitor

Sirtuin 2 (SIRT2) is a histone deacetylase (HDAC) and plays an important role in cell cycle progression. AGK-2 (1) inhibits mammalian SIRT2 with IC₅₀ = 3.5 μM.¹⁾, at the same time, 1 has less activity (at up to 40 μM) against SIRT1 and SIRT3. 1 also rescues dopamine neurons from α-synuclein–mediated toxicity in a Drosophila model of Parkinson’s disease.
