Overview

Information

Droxinostat (NS 41080) is a selective inhibitor ofHDAC, mostly for HDACs 6 and 8 withIC50of 2.47 μM and 1.46 μM, greater than 8-fold selective against HDAC3 and no inhibition to HDAC1, 2, 4, 5, 7, 9, and 10.
In vitro

Droxinostat is originally identified as a sensitizer of PPC-1 cells to FAS and TRAIL by downregulating the expression of c-Fas-associated death domain-like interleukin-1-converting enzyme-like inhibitory protein (c-FLIP). In PPC-1 cells cultured in suspension but not adherent conditions, Droxinostat (20 μM–60 μM) sensitizes cells to anoikis by initially activating caspase 8 with subsequent activation of the mitochondrial pathway. Similarly, Droxinostat also sensitizes other cancer cell lines including PC-3, DU-145, T47D, and OVCAR-3, but not LNCaP or MB-MDA-468, to anoikis or CH-11-induced apoptosis. However, the direct targets of Droxinostat remains enigma until recently. It is revealed that in histone deacetylases (HDAC) isoform 1-10, Droxinostat selective inhibits HDAC3, 6, and 8, with IC50 values of 16.9 μM, 2.47 μM, and 1.46 μM, respectively, without inhibiting other HDAC members (IC50 > 20 μM). In MCF-7 breast cancer cells, Droxinostat (10 μM–100 μM) sensitizes cells to apoptosis by decreasing c-FLIP_L and c-FLIP_S expression, reducing cell survival, and inducing apoptosis.

In vivo

In SCID mice models, Droxinostat (30 μM)-treated PPC-1 cells results in decreased distant tumor formation than untreated cells.
