In vitro	In HeLa cells, Domatinostat (4SC-202) induces hyperacetylation of histone H3 with EC50 of 1.1 μM. It induces a G2/M cell cycle arrest by interfering with the normal development of the mitotic spindle and causing collapsed spindle apparatus and multiple nucleation centres. In addition, this compound shows a broad anti-proliferative activity towards human cancer cell lines with a mean IC50 of 0.7 μM.
In vivo	Domatinostat (4SC-202) has high oral bioavailability in vivo, and shows high metabolic stability and a low plasma clearance. It (120 mg/kg p.o.) shows pronounced and robust anti-tumor activity in both A549 NSCLC xenograft and RKO27 colon carcinoma model.
