DS-6051 Chemical Properties,Uses,Production
Description
DS-6051b (Daiichi Sankyo, Japan) is an oral small molecule tyrosine kinase inhibitor that has demonstrated preclinical activity against ROS1 and NTRK1-3 rearrangements.
Uses
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[1][2].
in vivo
Taletrectinib (DS-6051b) free base (25-200 mg/kg; p.o.; once daily for 18 days) shows antitumor activity[1].
Taletrectinib free base (6.25-200?mg/kg; p.o.; once daily for 8 days) inhibits NTRK-rearranged cancer in Balb-c nu/nu mice bearing KM12 cells[1].
Taletrectinib free base (3-100 mg/kg; p.o.; once daily for 4 days) shows rapid tumor regression in the wild-type (WT) and the G2032R-mutant Ba/F3-bearing mice without severe body weight loss[1].
| Animal Model: | Balb-c nu/nu mice (bearing U-118 MG cells)[1] |
| Dosage: | 25, 50, 100, and 200?mg/kg |
| Administration: | P.o.; once daily for 18 days |
| Result: | Effectively inhibited tumor growth at ≥25?mg/kg without significant body weight loss. |
