生物活性

Citarinostat (ACY241) is a second generation potent, orally active and high-selective HDAC6 inhibitor with an IC50 of 2.6 nM (IC50s of 35 nM, 45 nM, 46 nM and 137 nM for HDAC1, HDAC2, HDAC3 and HDAC8, respectively). Citarinostat has anticancer effects.

体外研究(In Vitro)

Citarinostat (ACY241; 0-3 μM; 24 hours; A2780 cells) treatment with 300 nM results in increased hyperacetylation of α-tubulin, consistent with inhibition of the tubulin deacetylase HDAC6. In contrast, hyperacetylation of histone H3, a target of Class I HDACs, is only observed at doses above 1 μM. Low exposures of Citarinostat result in selective inhibition of HDAC6, while higher exposures lead to inhibition of Class I HDAC isozymes.
The single agent viability IC50 of Citarinostat (ACY241) ranged from 4.6-6.1 μM in A2780 and TOV-21G ovarian cancer and MDA-MD-231 breast cancer cells. Consistent with the viability assay, single agent Citarinostat modestly reduces proliferation at doses up to 3 μM without inducing apoptosis, while 10 μM of Citarinostat causes significant induction of apoptosis and completely suppresses proliferation.
