A cell-permeable carbazolohydroxamate compound that acts as a highly potent, reversible and active-site zinc-binding HDAC6 inhibitor with excellent selectivity among other HDAC isozymes (IC50=0.015, 0.854, 16.4uM for HDAC6, HDAC8 and HDAC1, respectively) with no activity towards HDAC2, 3, 4, 7, 9, 10 and 11 (IC50>30uM). Shown to induce a-tubulin hyperacetylation at 2.5uM, and offer complete neuroprotection in primary cortical rat neuronal cells against homocysteic acid (HCA)-induced oxidative stress at 10uM with no noticeable neurotoxicity.
