14325-05-4 Usage
Uses
Different sources of media describe the Uses of 14325-05-4 differently. You can refer to the following data:
1. Heme oxygenase (HO) converts protoheme to biliverdin, which in turn is enzymatically metabolized to bilirubin . While HO-2 is constitutively expressed, HO-1 can be induced by its heme substrate as well as by heavy metals, oxidizing agents, and other environmental stresses. TIN PROTOPORPHYRIN IX DICHLORIDE(SnPPIX) is a synthetic heme analog that selectively inhibits HO-1 (Ki = 11 nM) over HO-2 (IC50 = 7.5 μM). It also weakly inhibits endothelial nitric oxide synthase and soluble guanylyl cyclase (IC50s = 35 and 30 nM, respectively). SnPPIX prevents hyperbilirubinemia in neonates by blocking HO-1 activity that increases postnatally. It is rapidly cleared from plasma and persists in certain tissues, including kidney, liver, and spleen. SnPPIX is commonly used as a tool to study the role of HO-1 activity in cells and in animals.[Cayman Chemical]
2. Tin Protoporphyrin IX Dichloride is a selective inhibitor of heme oxygenase.
Check Digit Verification of cas no
The CAS Registry Mumber 14325-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,2 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14325-05:
(7*1)+(6*4)+(5*3)+(4*2)+(3*5)+(2*0)+(1*5)=74
74 % 10 = 4
So 14325-05-4 is a valid CAS Registry Number.

Page/Page column 6, (2012/10/08)
Embodiments describe methods of synthesizing metal mesoporphyrin compounds. In embodiments, a metal mesoporphyrin compound may be formed by hemin transmetallation and subsequent hydrogenation of the tin protoporphyrin IX to form a metal mesoporphyrin. In other embodiments, a method of synthesizing a metal mesoporphyrin compound comprises forming a protoporphyrin methyl ester from hemin and converting the protoporphyrin methyl ester intermediate to a metal mesoporphyrin compound through metal insertion and hydrogenation. In other embodiments, a metal mesoporphyrin compound may be formed from hemin by a hydrogen-free hydrogenation method to form a mesoporphyrin IX intermediate followed by metal insertion and hydrogenation. In embodiments, a method of synthesizing a metal mesoporphyrin compound comprises forming a mesoporphyrin IX dihydrochloride intermediate compound and converting the mesoporphyrin IX intermediate to a metal mesoporphyrin compound through metal insertion. In embodiments, a metal mesoporphyrin compound may be formed directly from hemin without isolation of any intermediates.
