Sirtuins catalyze the NAD(+) dependent deacetylation of N(epsilon)-acetyl lysine residues to nicotinamide, O'-acetyl-ADP-ribose (OAADPR) and N(epsilon)-deacetylated lysine. Here, an easy-to-synthesize Ac-Ala-Lys-Ala sequence has been used as a probe for the screening of novel N(epsilon)-modified lysine containing inhibitors against SIRT1 and SIRT2. N(epsilon)-Selenoacetyl and N(epsilon)-isothiovaleryl were the most potent moieties found in this study, comparable to the widely studied N(epsilon)-thioacetyl group. The N(epsilon)-3,3-dimethylacryl and N(epsilon)-isovaleryl moieties gave significant inhibition in comparison to the N(epsilon)-acetyl group present in the substrates. In addition, the studied N(epsilon)-alkanoyl, N(epsilon)-alpha,beta-unsaturated carbonyl and N(epsilon)-aroyl moieties showed that the acetyl binding pocket can accept rather large groups, but is sensitive to even small changes in electronic and steric properties of the N(epsilon)-modification. These results are applicable for further screening of N(epsilon)-acetyl analogues.
