475-31-0 Usage
Description
Different sources of media describe the Description of 475-31-0 differently. You can refer to the following data:
1. N-Cholylglycine. Bile salt, conjugate of cholate and glycine, usually
as the sodium salt. It acts as a detergent to solubilize fats for
absorption and is itself absorbed. It is used as a cholagogue and
choleretic.
2. Glycocholic acid is a glycine-conjugated form of the primary bile acid cholic acid and has roles in the emulsification of fats. It reduces expression of the gene encoding the farnesoid X receptor (FXR) and increases expression of the genes encoding the bile acid receptors TGR5 and S1PR2 in SNU-245 cells when used at a concentration of 1.6 μmol/ml. Glycocholic acid (250 μM) increases the intracellular accumulation and cytotoxicity of epirubicin in Caco-2 cells, as well as decreases expression of the genes encoding multidrug resistance protein 1 (MDR1), MDR-associated protein 1 (MRP1), and MRP2 when used alone or in combination with epirubicin. It increases absorption of epirubicin into everted sacs of rat ileum and jejunum when used at a concentration of 250 μM. The bile acid composition ratio of glycocholic acid is elevated in bile of patients with cholangiocarcinoma compared with patients with pancreatic cancer or benign biliary diseases. Serum levels of glycocholic acid are elevated in patients with hepatocellular carcinoma compared with healthy individuals.
Chemical Properties
Off-White Solid
Definition
ChEBI: A bile acid glycine conjugate having cholic acid as the bile acid component.
Purification Methods
Glycocholic acid crystallises from hot water as the sesquihydrate. Dry it at 110o in vacuo. An analytical sample is prepared by suspending the acid (4g) in H2O (400mL) at ~20o, heating to boiling with slow stirring, filtering hot and allowing to cool to ~20o. The acid is filtered off, washed with H2O, dried in air, recrystallised from 5% aqueous EtOH, washed well and dried over P2O5 in a moderate vacuum to constant weight. Recrystallisation from EtOH/EtOAc, and drying, gave the anhydrous acid. [Cortese & Bauman J Am Chem Soc 57 1393 1935, Bergstrom & Norman Acta Chem Scand 7 1126 1953, Beilstein 10 IV 2077.]
Check Digit Verification of cas no
The CAS Registry Mumber 475-31-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 475-31:
(5*4)+(4*7)+(3*5)+(2*3)+(1*1)=70
70 % 10 = 0
So 475-31-0 is a valid CAS Registry Number.

Synthesis, anticancer activities, antimicrobial activities and bioavailability of berberine-bile acid analogues

Fifteen berberine-bile acid analogues were synthesized. Anticancer activities of these analogues compared with berberine (BBR) were evaluated in vitro; among the analogues, A4, B4, and B5 had higher cytotoxicity than that of BBR. Most of the analogues showed higher antimicrobial activity against Staphylococcus aureus ATCC 25923 and Staphylococcus albus ATCC 8799 than that of BBR, but Bacillus subtilis AS 1.398 and Escherichia coli ATCC 31343 were not sensitive to all of the analogues. A4 and B4 were stable in the serum stability assay. B4 showed promising oral bioavailability in mice.
An improved procedure for the synthesis of glycine and taurine conjugates of bile acids
Tserng,Hachey,Klein
, p. 404 - 407 (2007/10/06)
Glycine and taurine conjugates of 5β cholanic acids have been synthesized using improved procedures based on the peptide coupling reagent, N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline. The conjugates are obtained in chromatographically pure form in yields higher than 90%. The use of this procedure in the large scale preparation of choly[1,2 13C2]glycine is described.
