FGFR3 Inhibitor

IMC-D11 (LY-3076226 antibody) is an anti-FGFR3 IgG1 monoclonal antibody with an EC₅₀ of approximately 0.1 nM against hFGFR3b and hFGFR3c. IMC-D11 inhibits the growth of FGFR3-dependent lung adenocarcinoma in mouse models and shows no effect on tumors that do not express FGFR3. IMC-D11 can serve as an ADC Antibody for ADC synthesis, such as LY3076226. IMC-D11 is applicable to research related to urothelial carcinoma, multiple myeloma, lung adenocarcinoma, as well as advanced or metastatic cancers.

FGFR-IN-27 is an orally active, broad-spectrum FGFR inhibitor, with an IC₅₀ of 0.24 nM against human FGFR1, 0.71 nM against FGFR2, 0.87 nM against FGFR3, and 6.50 nM against FGFR4. FGFR-IN-27 inhibits cancer cell proliferation and blocks tumor growth. FGFR-IN-27 reduces the phosphorylation levels of AKT and ERK, induces apoptosis and ferroptosis, increases ROS levels, and decreases GSH levels. FGFR-IN-27 can be used in the research of hepatocellular carcinoma.

FGFR-IN-28 is a FGFR inhibitor with inhibitory activity against multiple subtypes of the FGFR family, with an IC₅₀ of 4.4 nM against FGFR4. FGFR-IN-28 inhibits kinase activity and phosphorylation processes, and blocks the downstream MAPK and AKT signaling pathways. FGFR-IN-28 induces cellular DNA damage, cell cycle arrest, apoptosis and ferroptosis, and reduces the adhesion, invasion and metastasis abilities of cancer cells. FGFR-IN-28 exhibits anti-tumor activity in in vitro experiments on colon cancer cells, and inhibits tumor growth in colon cancer xenograft models. FGFR-IN-28 can be used in colon cancer-related research.

FGFR3-IN-12 is a selective fibroblast growth factor receptor 3 (FGFR3) inhibitor with an IC₅₀ of 6.8 nM. FGFR3-IN-12 shows an IC₅₀ of 19.2 nM against FGFR3^V555M and an IC₅₀ of 16.9 nM against TNK1 (Thirty-eight Negative Kinase 1). FGFR3-IN-12 inhibits cancer cells proliferation and induces caspase-mediated apoptosis. FGFR3-IN-12 exhibits antitumor activity in bladder cancer xenografts mice models. FGFR3-IN-12 can be used for the research of cancer, such as bladder cancer.

FGFR-IN-12 (example 14), a pyrimidinyl aryl urea derivative, is a potent FGFR inhibitor.
