Novel 3-Arylideneindolin-2-ones as Inhibitors of NAD⁺-Dependent Histone Deacetylases (Sirtuins)

Abstract

Class III histone deacetylases (sirtuins) play pivotal roles in many cellular processes. They are linked to extended lifespan and to the pathogenesis of cancer and neuronal disorders. We present novel sirtuin inhibitors based on a 6,7-dichloro-2-oxindole scaffold with low micromolar activity. In vitro activity was rationalized by docking studies, and hyperacetylation of sirtuin targets could be demonstrated in cell culture.
