TAS-119 is a potent, selective and orally active Aurora A inhibitor with an IC₅₀ of 1.0 nM. TAS-119 shows high selectivity for Aurora A over other protein kinases, including Aurora B (IC₅₀ of 95 nM). TAS-119 has potent antitumor activites^[1].

TAS-119 enhances the antiproliferative effect of Paclitaxel in a variety of human cancer cell lines, including Paclitaxel-resistant cells^[1].
TAS-119 (30-300 nM) dose dependently enhances cell growth inhibition by three taxanes (Paclitaxel, Docetaxel, and Cabazitaxel) in HeLa cells. TAS-119 induces mitotic accumulation predominantly in tumor cells, compared with that in normal diploid fibroblasts^[1].
