Description: CEP-11981, also known as ESK981, is an orally bioavailable inhibitor of vascular endothelial growth factor receptor (VEGFR) and Tie2 receptor tyrosine kinases with potential antiangiogenic and antineoplastic activities. Pan-VEGFR/Tie2 tyrosine kinase inhibitor CEP-11981 selectively binds to VEGFR and Tie2 receptor tyrosine kinases, which may result the inhibition of endothelial cell migration, proliferation and survival and the inhibition of tumor cell proliferation and tumor cell death.
