N-(3-α,7-α,12-α-Trihydroxycholan-24-oyl)glycin

BeschreibungGlycocholic 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.

VerwendenLabelled Glycocholic Acid. The product of conjugation of cholic acid with glycine; chief ingredient of the bile of herbivorous animals. In the weakly alkaline bile fluid glycocholic acid exists as the sodium salt.
