Protoporphyrin IX Usage And Synthesis
Uses
hepatoprotectant
Uses
Protoporphyrin IX has been used:
- as a standard in protoporphyrin assays
- in fluorescence spectra analysis
- to treat cells in cell culture to study heme-mediated ferroportin 1 transcription
Definition
ChEBI: A cyclic tetrapyrrole that consists of porphyrin bearing four methyl substituents at positions 3, 8, 13 and 17, two vinyl substituents at positions 7 and 12 and two 2-carboxyethyl substituents at positions 2 and 18. The parent of the class of protoporphyri s.
General Description
Protoporphyrin IX belongs to the porphyrin family, which are a class of tetrapyrroles. It is the iron-free form of hemin and amphiphilic in nature. It is the precursor of heme in its biosynthetic pathway.
Biochem/physiol Actions
Protoporphyrin IX?levels are elevated in?tumor?cells due to?metabolism anomalies?compared to normal?cells.
Enzyme inhibitor
This iiron-free, immediate precusor of heme (FWfree-acid = 562.67 g/mol; CAS 553-12-8; brownish-yellow solid; soluble in a number of organic solvents; disodium and dipotassium salts solublized in the presence of Tween 80) has lmax values in 25% HCl are 602.4, 582.2, and 557.2 nm. Protoporphryrin IX is also an activator of guanylate cyclase.

Purification Methods
Protoporphyrin IX (3,18-divinyl-2,7,13,17-tetramethylporphin-8,12-dipropionic acid, ooporphyrin) [553-12-8] M 562.7, pKEst ~ 4.8. Protoporphyrin IX is purified by dissolving (4g) in 98-100% HCOOH (85mL), diluting with dry Et2O (700mL) and keeping at 0o overnight. The precipitate is collected and washed with Et2O, then H2O, and dried in a vacuum at 50o over P2O5. It crystallises from aqueous pyridine and from Et2O in monoclinic, brownish-yellow prisms. The UV max values in 25% HCl are 557.2, 582.2 and 602.4nm. It is freely soluble in ethanolic HCl, AcOH, CHCl3, and Et2O containing AcOH. It forms sparingly soluble diNa and diK salts.

Toxicity evaluation
protoporphyrin IX, is highly toxic in the presence of light and molecular oxygen, killing photosynthetic plants very quickly through the generation of singlet oxygen.
