Allolithocholic acid modulates immune and metabolic pathways, regulates immune cell polarization, prevents M1 macrophage and Th17 CD4 cell polarization. Allolithocholic acid improves insulin sensitivity, reduces liver lipid accumulation, reverses liver immunological, inflammatory and metabolic signaling dysregulation, restores bile acid homeostasis, adipose tissue histopathology/function, and intestinal microbiota composition, modulates intestinal immunity. Allolithocholic acid can be used for the researches of cancer, inflammayion, immunology and metabolic disease.

Taurochenodeoxycholic acid (12-Deoxycholyltaurine) sodium is one of the main bioactive substances of animals' bile acid. Taurochenodeoxycholic acid sodium induces apoptosis and shows obvious anti-inflammatory and immune regulation properties.

5β-Cholanic acid is a hydrophobic modifier used to modify polymer carriers. 5β-Cholanic acid can improve the acid stability, cell penetration efficiency and drug sustained release ability of nanocarriers, and optimize the oral effectiveness of delivered molecules. 5β-Cholanic acid can covalently bind to Glycol chitosan (GC) to form a GC-CA conjugate, which optimizes the hydrophobic anchoring ability of nanoparticles and enables them to be stably adsorbed on the surface of PLGA nanoparticles. Such nanoparticles can resist dissociation in the gastric acid environment and maintain positive charge to enhance endocytic uptake by intestinal epithelial cells (such as Caco-2 cells). 5β-Cholanic acid can be used in the development of drug delivery systems.

Glycohyocholic acid (GHCA) is a primary conjugated bile acid formed by the conjugation of Hyocholic acid (HY-121238) and Glycine (HY-Y0966). Glycohyocholic acid can be used as a biomarker in the study of hepatitis C-related cirrhosis and diabetes.

3-Oxocholic acid is an oxo-bile acid metabolite and also a major degradation product from cholic by C. perfringens in the intestine. 3-Oxocholic acid is steroid acid found predominantly in bile of mammals.

Ursocholic acid, a bile acid present in mammalian bile, is converted to deoxycholic acid (UDC) by the mouse intestinal flora. Ursocholic acid acts as a gallstone dissolving agent in the liver through anti-apoptosis, anti-inflammatory, immunomodulatory, bile regulation, and coordinated changes in mitochondrial integrity and cell signaling, Ursocholic acid also has favorable effects on bones in patients with chronic cholestasis.

Taurohyodeoxycholic acid is an orally active 6 alpha-hydroxylated bile acid. Taurohyodeoxycholic acid decreases colonic MPO activity, TNF-α, lL-6 serum levels and the expression of COX-2.

Taurohyodeoxycholic acid prevents Taurochenodeoxycholic acid (HY-N2027)-induced hepatotoxicity in bile fistula rats. Taurohyodeoxycholic acid can be used for the study of nonalcoholic fatty liver disease (NAFLD), colitis and biliary fistula.

3β-Hydroxy-5-cholenoic acid is a steroidal monohydroxy bile acid and serves as a substrate for sulfation reactions. It is applicable to the research of extrahepatic biliary atresia and recurrent intrahepatic cholestasis of pregnancy.

Isodeoxycholic acid (7α,12α-Dihydroxycholanoic acid) is a 3β-hydroxylated secondary bile acid. Isodeoxycholic acid is produced by epimerization of deoxycholic acid by intestinal bacteria.

As a gut-restricted TGR5 agonist, cholic acid 7-sulfate binds to TGR5 on enteroendocrine L cells, induces GLP-1 secretion, and improves glucose tolerance in a TGR5-dependent manner. Cholic acid 7-sulfate also acts as an endogenous ligand for MR1, promoting the survival of mucosal-associated invariant T cells MAIT and the expression of homeostatic gene signatures, affecting MAIT cell development and function. Cholic acid 7-sulfate is mainly used in the research of diabetes and MAIT cell-related immune regulation.
