General description

A cell-permeable, potent, selective, reversible, and ATP-competitive inhibitor of TGF-β type I receptor (ALK5; IC₅₀ = 23 nM, 4 nM and 18 nM for ALK5 binding, ALK5 auto-phosphorylation, and TGF-β cellular assay in HepG2 cells, respectively). Minimally affects a panel of 9 closely related kinases including p38 MAPK (IC₅₀ >16 µM).

Biochem/physiol Actions

Cell permeable: yes

Primary Target
ALK5

Reversible: yes

Target IC₅₀: 23 nM, 4 nM and 18 nM for ALK5 binding, ALK5 auto-phosphorylation, and TGF-&beta

Packaging

Packaged under inert gas

Physical form

A 50 mM (5 mg/348 µl) sterile-filtered solution of TGF-β RI Kinase Inhibitor II, RepSox (Cat. No. 616452) in DMSO.

Preparation Note

Following initial thaw, aliquot and freeze (-20°C). Aliquots are stable for up to 6 months at -20°C. Use only fresh DMSO for further dilution.
