LBH589

LBH589 (Panobinostat, NVP-LBH589) is a novel deacetylase inhibitor and has been shown to induce acetylation of histone H3 and H4, increase p21 levels, disrupt the chaperone function of hsp90, and induce cell-cycle G1 phase accumulation and apoptosis of K562 cells and acute leukemia MV4-11 cells. LBH589 (Panobinostat, NVP-LBH589) has also recently been found to significantly increase in vitro the survival of motor neuron (SMN) protein levels in cells of patients suffering from spinal muscular atrophy.
