PCI-34051 is a potent, specific inhibitor of histone deacetylase 8 (HDAC8) with greater than 200-fold selectivity over the other HDAC isoforms, such as 1, 2, 3, 6 and 10. It induces caspase dependent apoptosis in cell lines derived from T-cell lymphomas or leukemias, but not in other hematopoietic or solid tumor lines. PCI-34051 does not cause detectable histone or tubulin acetylation and also does not inhibit growth or induce apoptosis in normal cells such as PBMCs or fibroblasts. Although a phospholipase C-gamma1 (PLCgamma1) defective line is resistant, cells defective in T-cell receptor signaling are still sensitive to PCI-34051 induced apoptosis.

Histone deacetylase activity
For PCI-34051 characterization, measurements were perfomed in a reaction volume of 100 μL using 96-well assay plates in a fluorescence plate reader. For each isozyme, the HDAC protein in reaction buffer (50 mM HEPES, 100 mM KCl, 0.001% Tween-20, 5% dimethyl sulfoxide, pH 7.4, supplemented with bovine serum albumin at concentrations of 0 ~ 0.05%) was mixed with PCI-34051 at various concentrations and allowed to incubate for 15 mins. Trypsin was added to a final concentration of 50 nM, and acetyl-Gly-Ala-(N-acetyl-Lys)-amino-4-methylcoumarin was added to a final concentration of 25 ~ 100 μM to initiate the reaction. After a 30 min lag time, the fluorescence was measured over a 30 min time frame using an excitation wavelength of 335 nm and a detection wavelength of 460 nm. The increase in fluorescence with time was used as the measure of the reaction rate.
