compound 86 [PMID: 26982234]   

GtoPdb Ligand ID: 9251

Compound class: Synthetic organic
Comment: Compound 86 is reported as a selective inhibitor of sirtuin 2 (SIRT2) [1], a NAD-dependent protein deacetylase with protective effects neurodegenerative disease. Compound 86 is shown to be competitive with NAD+ and the enzyme's peptide substrate, with acceptable blood-brain barrier penetrance (a property essential for any drug being developed for neuroprotective activity).

Drug-like SIRT2 inhibitors are being developed to determine if SIRT2 blockade could be of clinical benefit in Parkinson's disease [2].

Bioactivity Comments
Compound 86 is around 70-fold selective for SIRT2 compared to SIRT1 and SIRT3 in a biochemical enzyme activity assay [1]. In vitro, compound 86 protects SH-SY5Y cells against oligomeric α-synuclein toxicity, which is a cellular model of Parkinson's disease neurodegeneration [3-4].
