Description: PCI-34051 is a potent, histone deacetylase 8 (HDAC8)-specific inhibitor with >200-fold selectivity over the other HDAC isoforms. PCI-34051 induces caspase-dependent apoptosis in cell lines derived from T-cell lymphomas or leukemias, but not in other hematopoietic or solid tumor lines. Unlike broad-spectrum HDAC inhibitors, PCI-34051 does not cause detectable histone or tubulin acetylation. PCI-34051 could offer benefits including a greater therapeutic index for treating T-cell malignancies.
