OTS193320

Research use only, not for human use.

OTS193320 (OTS-193320) is a potent inhibitor of protein methyltransferase SUV39H2 with IC50 of 22.2 nM.

OTS193320 (OTS-193320) is a potent inhibitor of protein methyltransferase SUV39H2 with IC50 of 22.2 nM; significantly reduces global H3K9 tri-methylation (H3K9me3) in breast cancer cells in vitro and induces apoptotic cell death, 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; causes growth suppressive effect of SUV39H2-positive A549 lung cancer cells with IC50 of 0.38 uM.

Cell Viability Assay Cell Line:MCF-7, SK-BR-3, ZR-75-1, T-47D, MDA-MB-231, BT-20 breast cancer cell lines.Concentration:0-1 μM Incubation Time:72 hours Result:Had Growth inhibitory effect on MCF-7, SK-BR-3, ZR-75-1, T-47D, MDA-MB-231, and BT-20 breast cancer cell lines with IC50 values from 0.41 to 0.56 μM, respectively.Apoptosis AnalysisCell Line:MDA-MB-231 and BT-20 cells.Concentration:0.5 μM Incubation Time:48 hours Result:Showed an increase in the number of cells at early- and late-stage apoptosis.Western Blot Analysis Cell Line:MDA-MB-231 and BT-20 cells Concentration:0.125, 0.25, 0.5 μM Incubation Time:24 hours Result:Caused attenuation of H3K9me3 levels in a dose-dependent manner.
