    Product Description

    Tin(IV) protoporphyrin IX chloride is a synthetic heme analog that selectively inhibits HO-1 (Ki = 11 nM) over HO-2 (IC50 = 7.5 µM).1,2 It also weakly inhibits endothelial nitric oxide synthase and soluble guanylyl cyclase (IC50s = 35 and 30 nM, respectively).2 Tin(IV) protoporphyrin IX chloride prevents hyperbilirubinemia in neonates by blocking HO-1 activity that increases postnatally.1 It is rapidly cleared from plasma and persists in certain tissues, including kidney, liver, and spleen.3 Tin(IV) protoporphyrin IX chloride is commonly used as a tool to study the role of HO-1 activity in cells and in animals.4,5
