Description: SU6656 is a potent and selective dual inhibitor of Src family kinases and Aurora kinase. SU6656 modulates CTGF (connective tissue growth factor) expression in an ERK-dependent manner. SU6656 induces caspase-independent cell death in FRO anaplastic thyroid carcinoma cells and therapeutic synergy in human synovial sarcoma growth, invasion and angiogenesis in vivo.
