PF-06733804 is a potent inhibitor of pan-Trk in cell-based assays (IC50s: 8.4 nM, 6.2 nM, and 2.2 nM for TrkA, TrkB, and TrkC) with anti-hyperalgesic effect.
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].
Trk-IN-20 is a 3-vinylindazole derivative compound that effectively inhibits the functions of Trk kinases. It accomplishes this by suppressing the phosphorylation of TrkA, TrkB, and TrkC, with IC50 values of 1.6 nM, 2.9 nM, and 2.0 nM, respectively [1].
