5255-17-4 Usage

Description

Cholenic acid is a monohydroxy bile acid. It is a cholesterol oxidation product formed by 7α-hydroxylation of 27-hydroxycholesterol (Item Nos. 14790 | 14791), as well as a precursor in the biosynthesis of chenodeoxycholic acid . Levels of cholenic acid are increased in patients with neonatal liver disease harboring mutations in CYP7A1, the gene encoding 7α-hydroxylase, as well as in patients with intrahepatic and extrahepatic cholestasis.

Uses

5-Cholenic Acid-3β-ol is a bile acid of which the metabolism in humans results in the primary bile acids lithocholic acid and chenodeoxycholic. It is found in hgher concentrations in meconium of premature human babies when compared to full term babies.

Check Digit Verification of cas no

The CAS Registry Mumber 5255-17-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,5 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5255-17:
(6*5)+(5*2)+(4*5)+(3*5)+(2*1)+(1*7)=84
84 % 10 = 4
So 5255-17-4 is a valid CAS Registry Number.

Marine and semi-synthetic hydroxysteroids as new scaffolds for pregnane X receptor modulation

Sepe, Valentina,Di Leva, Francesco Saverio,D'Amore, Claudio,Festa, Carmen,De Marino, Simona,Renga, Barbara,D'Auria, Maria Valeria,Novellino, Ettore,Limongelli, Vittorio,D'Souza, Lisette,Majik, Mahesh,Zampella, Angela,Fiorucci, Stefano

In recent years many sterols with unusual structures and promising biological profiles have been identified from marine sources. Here we report the isolation of a series of 24-alkylated-hydroxysteroids from the soft coral Sinularia kavarattiensis, acting as pregnane X receptor (PXR) modulators. Starting from this scaffold a number of derivatives were prepared and evaluated for their ability to activate the PXR by assessing transactivation and quantifying gene expression. Our study reveals that ergost-5-en-3β-ol (4) induces PXR transactivation in HepG2 cells and stimulates the expression of the PXR target gene CYP3A4. To shed light on the molecular basis of the interaction between these ligands and PXR, we investigated, through docking simulations, the binding mechanism of the most potent compound of the series, 4, to the PXR. Our findings provide useful functional and structural information to guide further investigations and drug design.
