Applications : Taletrectinib free base is a potent, orally active ROS1/NTRK inhibitor with IC₅₀ values of 0.207 nM (ROS1), 0.622 nM (NTRK1), 2.28 nM (NTRK2), and 0.98 nM (NTRK3). In addition to its strong activity against wild‑type kinases, it inhibits ROS1 G2032R and other Crizotinib‑resistant ROS1 mutants, making it valuable for investigating resistance mechanisms in ROS1‑ and NTRK‑driven malignancies.
