An oral, selective dual inhibitor of Src and ABL kinase.

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.

An oral, selective dual inhibitor of Src and ABL kinase.

ChEBI: Saracatinib is a member of the class of quinazolines that is quinazoline substituted by (5-chloro-2H-1,3-benzodioxol-4-yl)amino, (oxan-4-yl)oxy and 2-(4-methylpiperazin-1-yl)ethoxy groups at positions 4, 5 and 7, respectively. It is a dual inhibitor of the tyrosine kinases c-Src and Abl (IC50 = 2.7 and 30 nM, respectively). Saracatinib was originally developed by AstraZeneca for the treatment of cancer but in 2019 it was granted orphan drug designation by the US Food and Drug Administration for the treatment of idiopathic pulmonary fibrosis (IPF), a type of lung disease that results in scarring (fibrosis) of the lungs. It has a role as an antineoplastic agent, an EC 2.7.10.2 (non-specific protein-tyrosine kinase) inhibitor, a radiosensitizing agent, an autophagy inducer, an apoptosis inducer and an anticoronaviral agent. It is a member of quinazolines, a secondary amino compound, a N-methylpiperazine, an aromatic ether, a member of oxanes, a member of benzodioxoles, an organochlorine compound and a diether.
