Mechanism of Action

Features	Urea-based HDAC6-selective inhibitor.
Targets/IC₅₀/Ki	HDAC6 (Cell-free assay) 5 nM
In vitro	In B16 murine melanoma cells, Nexturastat A leads to a dose-dependent increase of acetyl α-tubulin levels without a concomitant elevation of histone H3 acetylation. Moreover, this compound potently inhibits the growth of B16 melanoma cells with GI50 of 14.3 μM.
Kinase Assay	HDAC inhibition assays
Kinase Assay	HDAC inhibition assays are performed by Reaction Biology Corp. using isolated human, recombinant full2length HDAC1 and -6 from a baculovirus expression system in Sf9 cells. An acetylated fluorogenic peptide,RHKKAc, derived from residues 379-382 of p53 is used as substrate. The reaction buffer is made up of 50 mM Tris-HCl pH 8.0, 127 mM NaCl, 2.7 mM KCl, 1 mM MgCl₂, 1 mg/mL BSA, and a final concentration of 1% DMSO. Compounds are delivered in DMSO and delivered to enzyme mixture with preincubation of 5-10 min followed by substrate addition and incubation for 2 h at 30°C. Trichostatin A and developer are added to quench the reaction and generate fluorescence, respectively. Dose-response curves are generated starting at 30 μM compound with three-fold serial dilutions to generate a 10-dose plot. IC50 values are then generated from the resulting plots, and the values expressed are the average of duplicate trials ± standard deviation.
