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].

Dabogratinib (12.5 mg/kg; p.o.; twice daily) induces tumor regression in FGFR3::TACC3 fusion urothelial carcinoma xenograft models and FGFR3V555M urothelial carcinoma xenograft models[1].
Dabogratinib (8-14 mg/kg; p.o.; once daily; 4 weeks) dose-dependently increases the growth rate of wild-type mice and promotes their long bone growth in vivo[2].
Dabogratinib (1.2 mg/kg; s.c.; once daily; 15 days) promotes bone growth, improves skeletal proportions, optimizes growth plate structure, and increases the foramen magnum size in the Fgfr3Y367C/+ mouse model of achondroplasia (ACH)[2].
Dabogratinib (1.8 mg/kg; s.c.; once daily; 21 days) increases bone length, enlarges foramen magnum size and improves intervertebral disc morphology in the Fgfr3N534K/+ mouse model of HCH[2].
