Abstract:
:Inhibition of sirtuin 2 (SIRT2) is known to be protective against the toxicity of disease proteins in Parkinson's and Huntington's models of neurodegeneration. Previously, we developed SIRT2 inhibitors based on the 3-(N-arylsulfamoyl)benzamide scaffold, including3-(N-(4-bromophenyl)sulfamoyl)-N-(4-bromophenyl)benzamide(C2-8, 1a), which demonstrated neuroprotective effects in a Huntington's mouse model, but had low potency of SIRT2 inhibition. Here we report that N-methylation of 1a greatly increases its potency and results in excellent selectivity for SIRT2 over SIRT1 and SIRT3 isoforms. Structure-activity relationships observed for 1a analogs and docking simulation data suggest that the para-substituted amido moiety of these compounds could occupy two potential hydrophobic binding pockets in SIRT2. These results provide a direction for the design of potent drug-like SIRT2 inhibitors.
