Sunitinib Malate

Description

Sunitinib is a small molecule inhibitor of receptor tyrosine kinases, including FLK1 (K_i = 9 nM), PDGFRβ (K_i = 8 nM), and FLT3. It is at least 10-fold selective for FLK1 and PDGFRβ over a variety of tyrosine kinases in a panel, including EGFR, Cdk2, Met, IGFR-1, Abl, and Src. Sunitinib inhibits VEGF-dependent FLK1 and PDGF-dependent PDGFRβ phosphorylation (IC₅₀s = 10 and 10 nM, respectively) as well as phosphorylation of FLT3 and FLT3 carrying the activating internal tandem duplication mutation (FLT3-ITD; IC₅₀s = 250 and 50 nM, respectively). It decreases VEGF- and FGF-induced proliferation of human umbilical vein endothelial cells (HUVECs; IC₅₀s = 30 and 700 nM, respectively) and reduces tumor growth in a variety of mouse xenograft models when administered at doses ranging from 20 to 80 mg/kg per day. Formulations containing sunitinib have been used in the treatment of gastrointestinal stromal tumors and metastatic renal cell carcinoma.

The Uses of Sunitinib Malate

Sunitinib Malate (Sutent, SU11248) is a multi-targeted RTK inhibitor targeting VEGFR2 (Flk-1) and PDGFRβ with IC50 of 80 nM and 2 nM, and also inhibits c-Kit.

What are the applications of Application

Sunitinib Malate is an antineoplastic agent, Flk-1 inhibitor, and ATP-competitve inhibitor of PDGFRβ
