SNS-314 is an ATP-competitive and selective inhibitor of aurora kinases with IC50 values of 9 nM, 31 nM and 3 nM against Aurora A, Aurora B and Aurora C, respectively [1 and 2].
Aurora kinases are serine/threonine kinases that regulate mitosis of cells. They are found to be associated with the onset and propagation of cancer and over-expressed in various tumor cell lines such as melanoma, ovarian, colon, pancreatic and breast tumors. Therefore, aurora kinases are being evaluated as potential targets in cancer therapy .As a potent inhibitor of aurora kinase, SNS-314inhibited proliferation in a broad panel of tumor cell lines and showed potent anti-tumor activity in mice bearing HCT116 xenografts. Besides that, a mechanism of its action was found to be inhibiting the phosphorylation of histoneH3 at Ser10 [1 and 2].
In the FRET-based biochemical assay, SNS-314inhibited Aurora A, B and C with IC50 values of 9, 31 and 3 nM, respectively. When tested against a panel of 219 kinases, SNS-314 only inhibited 24 kinases of them by 65% or above. It suggested that SNS-314 was a selective inhibitor of aurora kinase. In cell-based assays, SNS-314 blocked the proliferation of cancer cells with IC50 value in the range from 1.8 nM (A2780) to 24 nM (HT29). In HCT-116 cells, SNS-314 treatment for 16 hours resulted in distinct cell-cycle defects .
In human tumor xenograft mouse models, administration of SNS-314 exerted significant anti-tumor activities against xenografts of PC-3, H1299, A2780, MDA-MB-231 and A375 cells. The TGI value achieved between 54% and 91% when the dose was 170 mg/kg. The administration also caused a profound and sustained inhibition of pHH3 which was a substrate of Aurora B .
