Saracatinib is a dual inhibitor of the tyrosine kinases c-Src and Abl (IC50 = 2.7 and 30 nM, respectively). It less effectively inhibits other receptor and non-receptor tyrosine kinases as well as assorted serine/threonine kinases. Saracatinib is orally available and blocks cell motility, migration, adhesion, invasion, proliferation, differentiation, and survival. Through its effects on c-Src, it reduces osteoclast bone resorption. Saracatinib also blocks denque virus RNA replication through its effect on Fyn kinase.
