OTS193320 (OTS-193320) is a potent inhibitor of protein methyltransferase SUV39H2 with IC50 of 22.2 nM.
OTS193320 significantly reduces global H3K9 tri-methylation (H3K9me3) in breast cancer cells in vitro and induces apoptotic cell death.
OTS193320 attenuates γ-H2AX levels in combination with doxorubicin compared with the DOX treatment alone, and causes a significant reduction in breast cancer cell viability when compared to the treatment with a single agent.
OTS193320 causes growth suppressive effect of SUV39H2-positive A549 lung cancer cells with IC50 of 0.38 uM.
