PCI-34051 is a potent and specific HDAC8 inhibitor with IC50 of 10 nM in a cell-free assay. PCI-34051 inhibits ovarian tumor line OVCAR-3 with a GI50 of 6 μM and 15% cell death. Neither significant tubulin nor histone acetylation is observed in the sensitive cell lines treated with PCI-34051 at concentrations less than 25 μM at 24 hours nor at earlier timepoints. PCI-34051 induces a selective cytotoxic effect in cell lines derived only from T-cell malignancies. PCI-34051 induces caspase-dependent apoptosis. PCI-34051 undergoes preclinical studies for cancer
