In biochemical assays, the IC50 value of BAY 1217389 is 0.63±0.27 nmol/L. It shows high selectivity against other kinases and found to bind to PDGFRβ (<10 nmol/L), Kit (between 10 and 100 nmol/L), CLK1, CLK2, CLK4, JNK1, JNK2, JNK3, LATS1, MAK, MAPKAP2, MERTK, p38β, PDGFRα, PIP5K1C, PRKD1, and RPS6KA5 (between 100 and 1,000 nmol/L). In cellular mechanistic assays, BAY1217389 abrogats nocodazole-induced SAC activity and induced premature exit from mitosis ("mitotic breakthrough"), resulting in multinuclearity and tumor cell death. It is found to inhibit cell proliferation with a median IC50 of 6.7 nmol/L (range 3 to >300 nmol/L).
In vivo
In vivo, BAY 1217389 achieves moderate efficacy in monotherapy in tumor xenograft studies. Its blood clearance is found to be low in the tested species. Vss is high and terminal half-lives were long. BAY 1217389 is administered orally to female NMRI mouse (1 mg/kg) and male Wistar rat (0.5 mg/kg). Peak plasma concentrations are observed between 1.5 and 7 hours. Oral bioavailability is high in rat and moderate in mouse.
