ALK-IN-9 (compound 40) is a highly effective ALK inhibitor. It demonstrates remarkable inhibitory activity against cell proliferation, with IC50 values of <0.2 nM for Ba F3-EML4-ALK, KM 12 (TPM3-TRKA), and KG-l cell (OP2-FGFR1).
Trk-IN-7 (compound I-6) is a highly potent inhibitor of TRK, exhibiting IC50 values ranging from 0.25-10 nM for TRKA, TRKB, and TRKC, respectively. In addition, Trk-IN-7 demonstrates notable inhibition against EML4-ALK (IC50 <15 nM), as well as ALK G1202R, ALK C1156Y, ALK R1275Q, ALK F1174L, ALK L1197M, and ALK G1269A (IC50 = 5-50 nM) [1].
CM-118 is a potent and selective dual inhibitor of c-Met and ALK which potently abrogates hepatocyte growth factor (HGF)-induced c-Met phosphorylation and cell migration, as well as phosphorylation of ALK, EML4-ALK, and ALK resistance mutants in transfected cells.
