AK-7 (420831-40-9) is a selective Sirt2 inhibitor (IC50=15.5 μM) which does not inhibit Sirt1 or Sirt3.1 It down regulates cholesterol biosynthesis genes in primary striatal neurons.1 AK-7 displays neuroprotective effects in Huntington's disease mouse models including improved motor function, extended survival and reduced brain atrophy all of which were associated with reduced aggregated mutant huntingtin.2 Ameliorate β-amyloid pathology and cognitive impairment in an Alzheimer's disease model.3
