Chemical information

Protoporfirina-Estaño; (Sn)-protoporphyrin.


Tin-protoporphyrin and the related compound tin-mesoporphyrin are metalloporphyrins which inhibit haem oxygenase, an enzyme involved in the breakdown of haem to bile pigments. They have been investigated as inhibitors of bilirubin production in hyperbilirubinaemia of various causes, and have been tried in porphyria.
