Sn(IV) Protoporphyrin IX

Catalog No.:  F-H080
MW: 750.26

Description:  Sn (IV) Protoporphyrin IX is an inhibitor heme oxygenase (the enzyme that catalyzes the conversion of heme to biliverdin in the heme degradation pathway) but has also been found to stimulate production of the heme oxygenase protein. Contrast the activity of Co (III) Protoporphyrin which has been found to have similar activities to Sn (IV) Protoporphyrin but with a greater enhancement of heme oxygenase synthesis activity such that heme oxygenase activity is actually increased when administered in vivo while in vitro administration inhibits heme oxygenase activity. Heme oxygenase has been implicated in tumor cell resistance to chemotherapy, reduction of free radical formation and inflammation, and associated with vascular repair.

Storage

Sn(IV) Protoporphyrin IX is stable for at least one year when stored as a solid, protected from moisture, at -20 °C. Protect from light.
