A cell-permeable, reversible, and ATP-competitive inhibitor of the tyrosine kinase activity of fibroblast growth factor receptor 1 (FGFR1; IC₅₀ = 10-20 µM in the presence of 1 mM ATP). Also inhibits aFGF-induced tyrosine phosphorylation of ERK1 and ERK2 (IC₅₀ = 10-20 µM). In contrast to SU4984 (Cat. No. 572625), SU5402 is only a weak inhibitor of tyrosine phosphorylation of the PDGF receptor and does not inhibit phosphorylation of the insulin receptor. Does not inhibit the kinase activity of the EGF receptor. A 10 mM (500 µg/169 µl) solution of SU5402 (Cat. No. 572631) in DMSO is also available.

Cell permeable: yes

Primary Target
Fibroblast growth factor receptor 1 (FGFR1)

Product competes with ATP.

Reversible: yes

Target IC₅₀: 10-20 &10-20 µM for fibroblast growth factor receptor 1 (FGFR1) in the presence of 1 mM ATP;M against FGFR1 in the presence of 1 mM ATP; 10-20 µM against inhibits aFGF-induced tyrosine phosphorylation of ERK1 and ERK2
