No significant inhibition against PLKs 1-3 is observed for CFI-400945 at a concentration of 50 μM. CFI-400945 can attenuate the growth of breast cell line, as well as other tumor cell lines significantly. CFI-400945 selectively inhibits PLK4 in cells, but also has certain activity against AURKB, TRKA, TRKB and Tie2/TEK (only 10 kinases showed more than 50% inhibition among 290 kinases). The cytokinesis failure and subsequent polyploidization by CFI-400945 treatment indicate that the cell death in cancer cell lines is at least partly achieved through inhibition of AURKB. No significant inhibition is observed for PLKs 1-3 (IC50s > 50 μM) probably due to the most divergent structure of PLK4 compared to other polo-like kinases 1-3. Cancer cells treated with CFI-400945 exhibit effects consistent with PLK4 kinase inhibition, including dysregulated centriole duplication, mitotic defects, and cell death. 体内研究:CFI-400945 is well tolerated in breast cancer xenograft models, in particular those deficient in the tumor suppressor PTEN. Upon intermittent oral dosing, in a mouse model of colon cancer, CFI-400945 is an effective inhibitor of HCT116 tumor growth and was well tolerated. CFI-400945 is absorbed rapidly after oral administration, reaching maximum plasma concentrations (Cmax) of 0.25-11.68 μg/mL for the doses tested (3.75-104 mg/kg). CFI-400945 can inhibit the growth of a range of tumor types and may be effective in a clinical setting even in advanced tumors. Following oral administration of efficacious doses of CFI-400945 in mice, plasma levels of CFI-400945 are sustained and remained above both the EC50 value for half-maximal inhibition of cellular PLK4 autophosphorylation and growth inhibition GI50 values for 24 hr. Moreover, CFI-400945 demonstrates dose-dependent antitumor activity. Analysis of xenograft tumors from mice treated with an efficacious dose of CFI-400945 shows a pharmacodynamic effect that is suggestive of complete rather than partial inhibition of PLK4 kinase activity. 产品信息订购:
