Tubastatin A HCl is a selective inhibitor of HDAC6 with IC50 value of 15 nM [1].
HDAC6 (histone deacetylase 6) is an enzyme and plays an important role in a variety of processes, including transcriptional regulation, cell cycle preogression and developmental events. Abnormal expression of HDAC6 is correlated with many kinds of diseases, including Alzheimer's disease and cancers [1].
Tubastatin A HCl is a potent HDAC6 inhibitor and has the most selective compared with other HDAC isoforms. When tested with primary cortical neuron cells, Tubastatin A HCl treatment protected HCA-induced neuronal cell death in a dose range from 5 μM to 10 μM [1]. In HaCaT cells, administration of Tubastatin A HCl prevented sodium arsenite from inducing association of Nrf2 mRNA with ribosomes and elevation of Nrf2 protein by selectively inhibitng HDAC6 activity and had no effect on other HDACs [2]. Using atomic force microscopy study, Ketene AN et al. revealed that Tubastatin A HCl increased cell elasticity by inhibiting HDAC6 [3].
