FGFR4-IN-14

FGFR4-IN-14 (Compound 27i) is a selective FGFR4 inhibitor with an IC50 of 2.4 nM, effectively inhibiting cell proliferation in V550L and N535K mutant strains. It shows IC50 values of 21 nM against Huh7 cells, 2.5 nM against BaF3/ETV6-FGFR4-V550L cells, and 171 nM against BaF3/ETV6-FGFR4-N535K cells. FGFR4-IN-14 demonstrates significant antitumor efficacy in the Huh7 xenograft model and is utilized in hepatocellular carcinoma (HCC) research [1].
