Taurocholic acid (TCA) is a taurine-conjugated form of the primary bile acid cholic acid . Serum levels of TCA are decreased in patients with Crohn's disease and those with ulcerative colitis with no extraintestinal manifestations, but are increased in patients with ulcerative colitis accompanied by hepatobiliary disease.

Protective effects of Taurocholic Acid on excessive hepatic lipid accumulation via regulation of bile acid metabolism in grouper
Food Funct 2022 Mar 7;13(5):3050-3062.PMID:35199809DOI:10.1039/d1fo04085e.
Dietary bile acid (BA) supplementation can notably ameliorate fatty liver disease caused by high dietary lipids, but the mechanism behind this is poorly understood. The present study was aimed at gaining insight into how TCA (Taurocholic Acid sodium) reduced hepatic lipid accumulation via the regulation of bile acid metabolism. We explored BA metabolism in juvenile hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂). Three trials were: (1) fed the control, high lipid (HD) or gradient TCA diet; (2) fed a BA diet with or without antibiotics; and (3) injected with an agonist or antagonist of TGR5 (G protein-coupled bile acid receptor 1) and FXR (farnesoid X receptor). The results showed that the TCA diet (about 900 mg kg-1) significantly reduced lipid accumulation in the liver, thus improving liver health. The HD suppressed the abundance of bile-salt hydrolase (BSH) microbes, thus decreasing the concentration of unconjugated primary BAs. TCA administration altered the gut microbial composition and weakened the effects of the HD, thus increasing the level of unconjugated BAs. TCA treatment increased the transport and reabsorption of BAs by activating the TGR5 and FXR signaling pathways, and increased the BA pool size. Furthermore, the presence of microbiota in the intestine increased BA reabsorption and the BA pool size. Our study revealed that exogenous TCA alters the structure of intestinal microbiota and BA composition, then activated the FXR expression, thus regulating the BA metabolism via enhanced BA reabsorption. This, in turn, reduced lipid accumulation and improved the health of the liver in grouper.
Bile acid salt binding with colesevelam HCl is not affected by suspension in common beverages
J Pharm Sci 2006 Dec;95(12):2751-9.PMID:16937334DOI:10.1002/jps.20734.
It has been previously reported that anions in common beverages may bind to bile acid sequestrants (BAS), reducing their capacity for binding bile acid salts. This study examined the ability of the novel BAS colesevelam hydrochloride (HCl), in vitro, to bind bile acid sodium salts following suspension in common beverages. Equilibrium binding was evaluated under conditions of constant time and varying concentrations of bile acid salts in simulated intestinal fluid (SIF). A stock solution of sodium salts of glycochenodeoxycholic acid (GCDC), taurodeoxycholic acid (TDC), and glycocholic acid (GC), was added to each prepared sample of colesevelam HCl. Bile acid salt binding was calculated by high-performance liquid chromatography (HPLC) analysis. Kinetics experiments were conducted using constant initial bile acid salt concentrations and varying binding times. The affinity, capacity, and kinetics of colesevelam HCl binding for GCDC, TDC, and GC were not significantly altered after suspension in water, carbonated water, Coca-Cola, Sprite, grape juice, orange juice, tomato juice, or Gatorade. The amount of bile acid sodium salt bound as a function of time was unchanged by pretreatment with any beverage tested. The in vitro binding characteristics of colesevelam HCl are unchanged by suspension in common beverages.
Bile acid and bile salt disrupt gastric mucosal barrier in the dog by different mechanisms
Am J Physiol 1982 Feb;242(2):G95-9.PMID:7065146DOI:10.1152/ajpgi.1982.242.2.G95.
The present study was undertaken to assess the mechanism by which protonated Taurocholic Acid disrupts the gastric mucosal barrier. By the criterion of lecithin solubilization, the critical micellar concentration of Taurocholic Acid (pH 1) was 4.5 mM, as opposed to 3.0 mM for sodium taurocholate (pH 7). In canine Heidenhain pouches, Taurocholic Acid significantly increased net forward diffusion of Na+ and backdiffusion of H+ at concentrations of 9, 4.5, and 3.5 mM, indicating that micelle formation was not required for disruption of the gastric mucosal barrier by this bile acid. Saturation of the 9 mM Taurocholic Acid solution with lecithin (and cholesterol) did not prevent disruption of the gastric mucosal barrier. At 9 mM, Taurocholic Acid was absorbed from the pouches at a mean rate of 1,150 +/- 115 nmol/min in contrast to an absorption rate of 225 +/- 10 nmol/min for sodium taurocholate at the same concentration. These findings indicate that, unlike ionized bile salts, disruption of the gastric mucosal barrier by Taurocholic Acid is mediated largely by uptake of bile acid by the gastric mucosa rather than dissolution of mucosal membrane lipids.
Oral absorption mechanism and anti-angiogenesis effect of taurocholic acid-linked heparin-docetaxel conjugates
J Control Release 2014 Mar 10;177:64-73.PMID:24412572DOI:10.1016/j.jconrel.2013.12.034.
Oral delivery is the preferred route to deliver therapeutics via nanoparticles due to ease of administration and patient acceptance. Here, we report on the findings of the absorption pathway of Taurocholic Acid (TCA)-linked heparin and docetaxel (DTX) conjugate, which we refer to as HDTA. We studied the oral absorption of HDTA using a Caco-2 cell transport system and an animal model. We have also used other absorption enhancers, such as ethylene glycol tetraacetic acid (EGTA), or inhibitors, such as sodium azide, to compare the relative permeability of HDTA conjugates. In vivo comparative studies were conducted using free TCA as a pre-administration and exhibited the maximum absorption site of the organ after oral administration of HDTA conjugates. HDTA was found to be absorbed mainly in the ileum and Caco-2 cell monolayer through passive diffusion and bile acid transporters. High fluorescence intensity of HDTA in mice came from the ileum, and it was eliminated from the body through colon. This novel formulation could be further investigated by clinical trials to find the prospect of oral anti-cancer drug delivery through anti-angiogenic treatment strategies.
Recovery of Caco-2 Cell Monolayers to Normal from the Transport-enhanced State Induced by Capric Acid sodium salt and its Monoacylglycerol
Biosci Biotechnol Biochem 1999;63(4):680-7.PMID:27389102DOI:10.1271/bbb.63.680.
Caco-2 cell monolayers were used as a model of the intestinal epithelium to investigate the recovery profile from the transport-enhanced state induced by the transport enhancers, capric acid sodium salt (C10FANa) and capric acid monoacylglycerol (C10MG). The transepithelial electrical resistance, MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide) assay, and lactate dehydrogenase (LDH) release rate were investigated. The cell monolayer recovered depending on the concentration of the enhancer and on the exposure time. The MTT assay revealed that the cells recovered their mitochondrial dehydrogenase activity without proliferation. The cell monolayer exposed to C10FANa released LDH to both the apical and basolateral sides, but to C10MG, only to the apical side. The results were compared with those for SDS and Taurocholic Acid sodium salt, and the effect of C10FANa was found to be different. These results suggest that the damage by MCFA compounds is recoverable and that the recovery can be assessed by an MTT assay, but that the LDH-release behavior is different among the enhancers.
