Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ SB-452533 acts as a competitive inhibitor at the capsaicin binding site on the transient receptor potential channel TRPV1 receptor with a pKb of 7.7 versus capsaicin and pIC50 of 7.0 versus pH. At higher concentrations, SB-452533 is also active at TRPM8 with an IC50 of 571 nM. It has a high clearance rate, so is not suitable for in vivo use._x000D_ Features and Benefits_x000D_ This compound is a featured product for Neuroscience research.
