1-Naphthohydroxamic acid
Based on 2 publication(s) in Google Scholar
1-Naphthohydroxamic acid (Compound 2) is a potent and selective HDAC8 inhibitor with an IC50 of 14 μM. 1-Naphthohydroxamic acid is more selectively for HDAC8 than class I HDAC1 and class II HDAC6 (IC50 >100 μM). 1-Naphthohydroxamic acid does not increase global histone H4 acetylation and also does not reduce total intracellular HDAC activity.1-Naphthohydroxamic acid can induce tubulin acetylation.

1-Naphthohydroxamic acid (compound 2; 20-40 μM; 0-144 ?hours; BE(2)-C, SK-N-BE(2) and SH-SY5Y cells) treatment reduces cell numbers in a concentration-dependent manner[2].
1-Naphthohydroxamic acid (compound 2) at concentrations in the range of its in vitro IC50 against HDAC8 results in reduced cell density and outgrowth of neurite-like structures that stained positive for neurofilament.1-Naphthohydroxamic acid reduces the formation of clones in soft-agar concentration dependently[2].
When either cell type (HeLa and HEK293 cells) is treated with 1-Naphthohydroxamic acid (compound 2; 0.8 μM, 4 μM, 20 μM or 100 μM), only tubulin becomes hyperacetylated[1].

Incubation Time:0 hours, 24 hours, 48 hours, 72 hours, 96 hours, and 144 hours
-
Result:Reduced cell numbers in a concentration-dependent manner.
Pharmacokinetic studies after intraperitoneal administration of the inhibitors identified the half-life of 1-Naphthohydroxamic acid to be ~15?min, with a plasma peak concentration of ~30?μM[3].
