Repotrectinib (TPX-0005) is a potent ROS1 (IC50=0.07 nM) and TRK (IC50=0.83/0.05/0.1 nM for TRKA/B/C) inhibitor. Repotrectinib potently inhibits WT ALK (IC50=1.01 nM). Repotrectinib has anti-cancer activity.
Repotrectinib (TPX-0005) inhibits mutant ALKs including ALK G1202R (IC50=1.26 nM) and ALK L1196M (IC50=1.08 nM). Repotrectinib also inhibits a variety of other kinases, including JAK2, LYN, Src, and FAK (IC50=1.04, 1.66, 5.3, and 6.96 nM, respectively)[1]. Repotrectinib effectively overcomes this primary resistance (IC50=100 nM in cell proliferation assay) with strong inhibition of the phosphorylation of EML4-ALK (IC50=13 nM) and the SRC substrate paxillin (IC50=107 nM). Repotrectinib inhibits H2228 cell migration in a wound healing assay with similar activity to saracatinib[1].
Repotrectinib (TPX-0005) effectively inhibits tumor growth in vivo in ALK WT and ALK G1202R xenografts[1].
