BLU-554 is a selective inhibitor of fibroblast growth factor receptor 4 (FGFR4) (IC50 = 5nM) [1]. BLU-554 selectively inhibits the activity of FGFR4 kinase, blocking the FGF19-FGFR4 pathway, thereby inhibiting the proliferation and growth of tumor cells [2]. BLU-554 is commonly used to treat hepatocellular carcinoma [3-4].
In MKN-45 cells, BLU-554 (0.05μM, 0.5μM, 5μM; 48h) inhibit the proliferation of gastric cancer cell line MKN-45 [5]. In HuH-7 and JHH-7 cells, BLU-554 (0-1250nM; 12h, 48h) can effectively inhibit FGFR4 activity in cells [6]. in PC9-4X cells, BLU-554 (1μM; 72h) reduces the IC50 of gefitinib [7].
In SW480-ELF4 cells subcutaneous tumor mice model, combination of BLU-554 (10mg/kg; ig; 9 weeks) and KX2-391 significantly inhibits ELF4-mediated CRC metastasis [8]. In Hepa1-6-ETV4 xenograft mice models, BLU-554 (100mg/kg; ig; 9 weeks) monotherapy partially reduced lung metastasis and lengthened the OS of the Hepa1-6-ETV4 [9].
