Opis

Opis ogólny

A cell-permeable carbazolohydroxamate that acts as a highly potent HDAC6-selective inhibitor (IC₅₀ = 15 nM) with much reduced or no activity against other known HDACs. Effectively prevents neuronal cell death (by ≥95% at 10 µM) upon oxidative stress induction by HCA and selectively induces cellular α-tubulin, but not histone H4, hyperacetylation (2.5 to 5 µM) in primary rat cortical neuron cultures.

A cell-permeable carbazolohydroxamate whose zinc-chelating hydroxamic acid moiety and catalytic channel rim-targeting aromatic cap structure render it a highly potent HDAC6-selective inhibitor (IC₅₀ = 15 nM against recombinant human HDAC6) with much reduced or no activity against HDAC8, HDAC1 (IC₅₀ = 0.854 and 16.4 µM, respectively), and other known HDACs (HDAC2/3/4/5/7/9/10/11; IC₅₀ >30 µM). Shown to selectively block HDAC6-, but not HDAC1-, dependent cellular deacetylation as evidenced by its selective induction (2.5 to 5 µM) of α-tubulin, but not histone H4, hyperacetylation in cultured primary rat cortical neurons. Although failing to block cellular glutathione depletion by homocysteic acid (HCA), Tubastatin A nevertheless is reported to prevent neuronal cell death upon oxidative stress induction by HCA in a dose-dependent manner (≥95% protection at 10 µM), presumably by preventing peroxiredoxins deacetylation.
