Description: Tubastatin A is a potent and selective HDAC6 inhibitor. Tubastatin A demonstrates 1093-fold selectivity over HDAC1 (IC50 values of 15 nM for HDAC6 vs 16.4 µM for HDAC1). Tubastatin A was substantially more selective than the known HDAC6 inhibitor Tubacin at all isozymes except HDAC8. Tubastatin A is a potent HDAC6 inhibitor with an IC50 value of 15 nM. Comparatively, it demonstrates over 1,000-fold selectivity against all other HDAC isoforms (IC50 >16 μM), excluding HDAC8 (IC50= 0.9 μM). Tubastatin A induces α-tubulin hyperacetylation at 2.5 μM in primary cortical neuron cultures. In a model of oxidative stress induced by glutathione depletion, tubastatin A displays dose-dependent neuronal protection of primary cortical neuron cultures at 5-10 μM.
