产品描述：
Droxinostat is a selective inhibitor of HDAC3, HDAC6, and HDAC8 with IC50 value of 16.9 ± 5.0 μM, 2.47 ± 1.09 μM, and 1.46 ± 0.11 μM, respectively [1].

HDACs (histone deacetylases) are enzymes responsible of the deacetylation of lysine that residues of core histones and play a pivotal role in controlling chromatin remodeling and transcriptional activation. It is also reported that HDACs control the acetylation and activation status of multiple non-histone proteins, including the heat shock protein 90 (Hsp90) which is an essential molecular chaperone for fungal virulence and antifungal resistance. Multiple HDACs have been identified and HDAC1 to HDAC10 are shown to express in malignant cells which reminds the HDAC inhibitor as a target for cancer therapy [2] [3].

Droxinostat is a selective HDAC inhibitor and is different from the known pan-HDACi TSA which inhibits all tested HDAC. When tested with prostate cancer line PPC-1 cells, droxinostat treatment selectively inhibited HDAC3, HDAC6, and HDAC8 activity at the concentration of 50 μM/L which sensitized cells to death ligands [1]. In androgen-dependent CaP cells, administration of droxinostat selectively inhibited HDACs and downregulated c-FLP expression which resulted in cells apoptosis [4].
