Isotope-Labeled Bile Acids

Cholic acid-d₄ is the deuterium labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Chenodeoxycholic Acid-d₄ is the deuterium labeled Chenodeoxycholic Acid. Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

Deoxycholic acid-d₄ is the deuterium labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

Lithocholic acid-d₄ is the deuterium labeled Lithocholic acid, which is a toxic secondary bile acid.

Ursodeoxycholic acid-2,2,4,4-d₄ is the deuterium labeled Ursodeoxycholic acid (HY-13771). Ursodeoxycholic acid is a secondary bile acid issued from the transformation of (cheno)deoxycholic acid by intestinal bacteria, acting as a key regulator of the intestinal barrier integrity and essential for lipid metabolism. Ursodeoxycholic acid acts as signaling molecule, exerting its effects by interacting with bile acid activated receptors, including G-protein coupled bile acid receptor 5 (TGR5, GPCR19) and the farnesoid X receptor (FXR). Ursodeoxycholic acid can be used for the research of a variety of hepatic and gastrointestinal diseases. Ursodeoxycholic acid also reduces ACE2 expression and is beneficial for reducing SARS-CoV-2 infection.

Cholic acid-d₅ is the deuterium labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Cholic acid-¹³C is the ¹³C-labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Chenodeoxycholic acid-d₅ is the deuterium labeled Chenodeoxycholic Acid. Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

Deoxycholic acid-¹³C is the ¹³C-labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

Epicoprostanol-d₅ is the deuterium labeled Epicoprostanol. Epicoprostanol is the compound found in adipocere.

Deoxycholic acid-d₅ is the deuterium labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

Isoallolithocholic acid-d₂ is the deuterium labeled Isoallolithocholic acid (HY-B0172A). Isoallolithocholic acid is a T cell regulator and enhances regulatory T cells (Tregs) differentiation.

Chenodeoxycholic acid-¹³C is the ¹³C-labeled Chenodeoxycholic Acid. Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

Hyocholic Acid-d₄ is the deuterium labeled Hyocholic Acid.

Glycohyocholic acid-d₄ is the deuterium labeled Glycohyocholic acid (HY-122141). Glycohyocholic acid (GHCA) is a primary conjugated bile acid formed by the conjugation of Cholic acid (HY-N0324) and Glycine (HY-Y0966). Glycohyocholic acid can be used in the study of hepatitis C-related cirrhosis and diabetes mellitus.

β-Hyodeoxycholic acid-d₄ (Isohyodeoxycholic acid-d₄) is the deuterium labeled β-Hyodeoxycholic acid.

7α,25-Dihydroxycholesterol-d₆ is deuterium labeled 7α,25-Dihydroxycholesterol. 7α, 25-dihydroxycholesterol (7α,25-OHC) is a potent and selective agonist and endogenous ligand of the orphan GPCR receptor EBI2 (GPR183). 7α, 25-dihydroxycholesterol is highly

α-Muricholic acid-d₅ is the deuterium labeled α-Muricholic acid. α-Muricholic acid is the most abundant primary bile acid in rodents.

Deoxycholic acid-d₆ is the deuterium labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

3α,7α-Dihydroxycoprostanic acid-d₃ is the deuterium labeled 3α,7α-Dihydroxycoprostanic acid (HY-113097). 3α,7α-Dihydroxycoprostanic acid is an endogenous metabolite. 3α,7α-Dihydroxycoprostanic acid, a bile acid, is the precursor to chenodeoxycholic acid.
