Taletrectinib free base
Based on 1 Customer Validation
Taletrectinib (DS-6051b) free base is a potent, orally active, and next-generation selective ROS1/NTRK inhibitor. Taletrectinib free base potently inhibits recombinant ROS1, NTRK1, NTRK2, and NTRK3 with IC50s of 0.207, 0.622, 2.28, and 0.98 nM, respectively. Taletrectinib free base also inhibits ROS1 G2032R and other Crizotinib-resistant ROS1 mutants.

The IC50 of Taletrectinib free base (1-1000 nM; 72 hours) against Ba/F3-TPM3-NTRK1, Ba/F3-ETV6-NTRK1, -NTRK2, -NTRK3, or KM12 cells is ~3-20 nM[1].
Taletrectinib free base (0.001-1000 nM; 2 hours) dose dependently inhibited autophosphorylation of ROS1 in U-118-MG cells in vitro[1].
Taletrectinib (DS-6051b) free base potently inhibits autophosphorylation of ROS1 in JFCR-165, JFCR-168, and MGH193-1B cells[1].
Taletrectinib free base partially suppresses phospho-NTRK1 at 10 nM, and completely suppresses by 100 nM. Taletrectinib free base potently inhibits recombinant ROS1, NTRK1, and NTRK3 in sub-nanomolar concentration in an ATP-competitive manner. Taletrectinib free base almost completely inhibits ACK, ALK, DDR1, and LTK at 0.2 μM among 160 kinases in the presence of 1 mM ATP, but did not inhibit other 152 kinases strongly[1].
Taletrectinib free base effectively inhibits Crizotinib-resistant ROS1 secondary mutations, including G2032R solvent front mutation[1].
