Dabogratinib
Based on 1 Customer Validation
Dabogratinib (TYRA-300) is an orally active, selective FGFR3 inhibitor with an IC50 of 11 nM. Dabogratinib exhibits antitumor activity against urothelial carcinoma and solid tumors. Dabogratinib downregulates the FGFR3 and ERK1/2 signaling pathways, and induces tumor growth inhibition and regression in FGFR3-altered xenograft models. Dabogratinib promotes chondrocyte proliferation and differentiation, drives endochondral bone formation and overall body growth, partially restores long bone proportions, and improves craniofacial and spinal morphology. Dabogratinib can be used for the research of metastatic urothelial carcinoma, achondroplasia and hypochondroplasia.

Dabogratinib (0.046 nM-3 μM; 2 h) induces dose-dependent downregulation of the FGFR3 downstream signaling pathway (assessed by pERK1/2 levels) in RT112/84, RT112/84-V555M and UM-UC-14 bladder cancer cell lines[1].
Dabogratinib inhibits the viability of FGFR3-driven bladder cancer cell lines, with IC50 values of 9 nM for the RT112/84 cell line, 17 nM for the RT112/84-V555M cell line, and 16 nM for the UM-UC-14 cell line[1].
