What is PROTOPORPHYRINATO ZINC?

The Uses of PROTOPORPHYRINATO ZINC

Zinc Protoporphyrin is a metabolite formed during biosynthesis and is used to evaluate iron nutrition and metabolism.

What are the applications of Application

Zinc Protoporphyrin-9 is a potent, selective inhibitor of heme oxygenase, GCS, NOS1, NOS2, and NOS3.

General Description

A potent and selective inhibitor of heme oxygenase, the enzyme which generates carbon monoxide (CO) and biliverdin. Inhibits soluble guanylyl cyclase and produces a time- and concentration-dependent inactivation of all three isoforms of nitric oxide synthase (IC₅₀ = 800 nM, 4 μM, and 5 μM for nNOS, iNOS, and eNOS, respectively). Inhibits relaxation induced by acetylcholine, ANP, and VIP in isolated rat aorta. Blocks interleukin-1 and prevents induction of long-term potentiation. Also useful as an indicator of iron-deficient erythropoiesis. Does not cross the blood-brain barrier.

Biological Activity

Inhibitor of heme oxygenase, which generates the putative neurotransmitter CO.

Biochem/physiol Actions

Primary Targetheme oxygenase
