fgfr4 in 4

FGFR4-IN-4 is a FGFR4 inhibitor with anti-tumor activity.

Roblitinib (FGF-401) is an inhibitor of human fibroblast growth factor receptor 4 (FGFR4) with potential antineoplastic activity. Upon administration, Roblitinib binds to and inhibits FGFR4, leading to the inhibition of tumor cell proliferation in FGFR4-overexpressing cells. It is a receptor tyrosine kinase upregulated in certain tumor cells and involved in proliferation, differentiation, angiogenesis, and survival.

FGFR-IN-16 (compound 7N) is a potent inhibitor of FGFR1, FGFR2, and FGFR4, exhibiting IC50 values of 8 nM, 4 nM, and 3.8 nM respectively. It plays a crucial role in cancer research.

FGFRs-IN-1 (Compound A16) is an orally active inhibitor targeting FGFR1 2 3 4, with IC50 values of 2.3, 7, 11, and 163 nM respectively. It also inhibits VEGFR1 2 3, Abl, and Flt3, with IC50 values of 61, 176, 112, 26, and 353 nM. The compound shows weak inhibition of CYP enzymes. FGFRs-IN-1 reduces the expression of α-SMA and collagen I, and it inhibits epithelial-mesenchymal transition (EMT) in A549 cells stimulated by TGF-β1. Additionally, FGFRs-IN-1 demonstrates anti-inflammatory activity in mouse models of lung fibrosis induced by Bleomycin and liver fibrosis induced by CCl4.

FGFR4-IN-5, a covalent FGFR4 inhibitor, demonstrates potency and selectivity with an IC50 value of 6.5 nM. Exhibiting significant in vivo anti-tumor activity, it is applicable for research in hepatocellular carcinoma [1].

Irpagratinib (ABSK011) is an orally active and highly effective FGFR4 antagonist with antitumor activity, inhibiting FGFR4 autophosphorylation and blocking FGFR4 signaling to downstream pathways. It is used in studies of gastrointestinal diseases and cancer.

FGFR4-IN-16 (CY-15-2) is a covalent inhibitor of FGFR-4, employed in cancer research [1].

CYY292 is a chemical compound acting as an inhibitor of PDGFRα, PDGFRβ, FGFR1, -2, and -3, with respective IC50 values of 5.35, 4.6, 28, 28, and 78 nM. It exhibits selectivity over FGFR4 (IC50 > 1,000 nM) while also targeting c-Kit, VEGFR2, VEGFR1, and IGF-1R (IC50 values of 67, 33, 36, and 75 nM, respectively). Additionally, CYY292 inhibits EGFR, BTK, Cdk4/cyclin D3, and MET with IC50 values of 128, 198, 214, and 396 nM, respectively. This compound demonstrates efficacy in arresting the proliferation of various osteosarcoma cell lines—MG-63, U2OS, MNNG/HOS, and Saos-2—with IC50s ranging from 0.72 to 1.36 µM. Moreover, CYY292 at 0.3 and 0.5 µM concentrations inhibits migration and invasion in glioblastoma cells (U87MG and LN-229) and, at a dose of 30 mg/kg, decreases tumor volume and enhances survival in a U87MG orthotopic mouse xenograft model.

FGFR4-IN-1 is a potent FGFR4 inhibitor (IC50: 0.7 nM).
