Information
Taletrectinib (DS-6051b, AB-106) is a new-generation selectiveROS1/NTRKinhibitor with ic50 of 0.207 nM,0.622 nM,2.28 nM and 0.980 nM for ROS1,NTRK1,NTRK2 and NTRK3,respectively.
Targets
ROS1 (Cell-free assay); TrkA (Cell-free assay); TrkC (Cell-free assay); TrkB (Cell-free assay) 0.207 nM; 0.622 nM; 0.980 nM; 2.28 nM
In vitro
DS-6051b inhibited the growth of the CD74-ROS1 overexpressed Ba/F3 cells and the ROS1 fusion-positive HCC78 cancer cell line.DS-6051b potently inhibited autophosphorylation of ROS1 in CD74-ROS1–expressed Ba/F3 cells and the SLC34A2-ROS1 harboring HCC78 cells at approximately single-digit to double-digit nanomolar concentration.
In vivo
In vivo experiments using the KM12-bearing mouse xenograft model shows that DS-6051b induced tumor shrinkage at a ≥50\u2009mg/kg or higher treatment dose without significant body weight loss.
