General description

A cell-permeable 4-thiazolyl-2-phenylaminopyrimidine compound that acts as a potent, reversible and ATP-competitive inhibitor of spleen tyrosine kinase (Syk) (Ki = 9nM). Exhibits excellent selectivity over Cdk2 (Ki ≥ 3.33 µM); ROCK Ki = 2.3 µM), Src Ki ≥ 3.33 µM) and ZAP 70 (Ki = 240 nM). Shown to inhibit mast cell degranulation (IC50 = 70 nM) that is commonly observed in asthma and other allergic diseases.

Rearranged during transfection (RET) is a tyrosine kinase oncogenic receptor, activated in several cancers including non-small-cell lung cancer (NSCLC). Multiple kinase inhibitors vandetanib and cabozantinib are commonly used in the treatment of RET-positive NSCLC. However, specificity, toxicity, and reduced efficacy
