[CAS NO. 1554458-53-5]  BAY 1217389

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).
