HPOB is a highly potent and selective inhibitor of histone deacetylase 6 (HDAC6) with IC50 of 56 nM, >30 fold less potent against other HDACs.target: HDAC6 [1]IC 50: 56nM [1]In vitro: HPOB causes growth inhibition of normal and transformed cells but does not induce cell death. HPOB enhances the effectiveness of DNA-damaging anticancer drugs in transformed cells but not normal cells. [1] Neuroprotective effect of HPOB demonstrated the crucial role of HDAC6 inhibition in reducing Cort-induced apoptosis in PC12 cells. Pre-treatment with HPOB remarkably reduces Cort-induced cytotoxicity and confirms the anti-apoptotic effect of HPOB via the caspase-3 activity assay and H33342/PI and TUNEL double staining. [2]In vivo: on corticosterone (Cort)-induced apoptosis and explors the possible mechanism of action of HPOB in rat adrenal pheochromocytoma (PC12) cells, which possesses typical neuron features and expresses high levels of glucocorticoid receptors.
