Scriptaid, identified by a high-throughput transcriptional screening, is a novel histone deacetylase (HDAC) with specific potency towards class I HDACs (50% inhibition concentration IC50 values of 0.6 μM for HDAC1 and HDAC3 and 1 μM for HDAC8). Scriptaid shares a similar chemical structure with several others hydroxamic acid-containing HDAC inhibitors (such as TSA and nullscript), which consists of a hydroxamic acid group, an aliphatic chain and an aromatic cap at the other end. Scriptaid has the potential to be used for the treatment of glioblastoma multiforme (GBM), one of the most challenging solid cancers to treat, for its ability to induce apoptosis in glioblastoma cells.
