What is GSK-2256098?

Description

GSK2256098 is an inhibitor of focal adhesion kinase (FAK). It is selective for FAK, inhibiting only FAK greater than 50% in a panel of 261 kinases. GSK2256098 inhibits FAK autophosphorylation at tyrosine 397 (Y397) in OVCAR8 ovarian, U87MG glioblastoma, and A549 lung cancer cell lines (IC₅₀s = 15, 8.5, and 12 nM, respectively). It induces apoptosis and increases PARP levels, decreases viability (IC₅₀ = 25 μM), and inhibits colony formation in L3.6P1 cells. GSK2256098 (75 mg/kg per day) also leads to lower tumor weight and fewer metastases in the Ishikawa orthotopic mouse model of uterine cancer.

The Uses of GSK-2256098

GSK 2256098 is FAK inhibitor. It can be used in biological study of molecular pathways: endothelial cell FAK-?A target for cancer treatment.
