(A) Structure of K0706. The boxed areas indicate sub-structure elements shared with ponatinib (blue box) and dasatinib (green box), which are shown for comparison. (B) Cellular IC50 values for K0706 in BCR-ABL1-positive and -negative cell lines. Note: Table S1: Comparison of K0706 to the BCR-ABL1 TKIs bosutinib, nilotinib, dasatinib, and ponatinib. (C) Immunoblot analysis of phosphorylation of BCR-ABL1 (pBCR-ABL1) in Ba/F3 cells expressing BCR-ABL1, BCR-ABL1L248V, BCR-ABL1Y253H, BCR-ABL1E255V, or BCR-ABLT315I following exposure to K0706.
