CHR-6494 TFA

CHR-6494 TFA is a potent haspin inhibitor, with an IC50 of 2 nM. It inhibits histone H3T3 phosphorylation. CHR-6494 TFA induces the apoptosis of cancer cells, including melanoma and breast cancer. CHR-6494 TFA can be used in the research of cancer. (In Vitro) :Administration of CHR-6494 (TFA; 0-10-5 nM; 72 hours) dose-dependently inhibits the growth of cancer cells, such as HCT-116, HeLa, MDA-MB-231, and Wi-38 cells, with an IC50s of 500 nM, 473 nM, 752 nM and 1059 nM, respectively. Administration of CHR-6494 (TFA; 500 nM) produces a mitotic catastrophe with abnormal morphology of the mitotic spindle and centrosome amplification, and upregulates the spindle assembly checkpoint protein BUB1 and the marker of mitotic arrest cyclin B1. (In Vivo) :Administration of CHR-6494 (TFA; 50 mg/kg; i.p. in two cycles of five consecutive days for 15 days) inhibits the growth of tumor and no obvious body weight change is observed in nude mice bearing HCT-116 human colorectal cancer cells.
