Protoporphyrin IX

Protoporphyrin IX free acid, as distinct from its zinc salt (which inhibits heme oxygenase), activates soluble guanylyl cyclase (sGC) by binding directly to the enzyme. A useful reagent in cases where the use of nitric oxide (NO) or nitric oxide donors is undesirable.


  • Guanylyl cyclase activator


Purple to dark brown solid.


Dissolve initially in 0.1M base (Tris base or NaOH), then add water miscible organic solvent (EtOH (10mg/ml), MeOH, DMSO (10mg/ml), DMF) until solution is 50/50 base/solvent. When a clear solution is obtained, it can be diluted into an aqueous medium and titrated or buffered to any pH>7. Use immediately.
