    Description: GW441756 is a novel, potent and selective inhibitor of TrkA (Tropomyosin-related kinase A) with IC50 of 2 nM, with very little activity to c-Raf1 and CDK2. The activity of TrkA kinase can affect its downstream signaling and involves in many biological processes including proliferation, differentiation and apoptosis. In human muscle sarcoma cancer cell line HTB114, treatment of GW441756 dose-dependently suppresses neoplastic proliferation and induces apoptosis. Trk inhibition reduces cell proliferation and potentiates the effects of chemotherapeutic agents in Ewing sarcoma.

    In Vitro

    In vitro activity: GW441756 can specifically block TrkA-induced cell death in a dose-dependent manner. GW441756 can block TrkA-mediated γH2AX production and apoptosis in TrkA-overexpressing cells.

    Kinase Assay: GW 441756 is a specific Tropomyosin-related kinase A (TrkA) inhibitor with an IC50 value of 2 nM; little activity to c-Raf1 and CDK2. IC50 Value: 2 nM. 

    Cell Assay: GW441756 specifically blocked TrkA-induced cell death in a dose-dependent manner, but there was no effect in uninduced cells. TrkA ability to induce γH2AX production was significantly downregulated by both K-252a and GW441756 in the absence of DNA damage inducer. In addition, it was also suppressed by K-252a during DNA damage by doxorubicin treatment, but not by GW441756
