• 개요

  Tauroursodeoxycholic acid (TUDCA) is a hydrophilic bile acid synthesized in hepatocytes by the conjugation of ursodeoxycholic acid (UDCA) with the amino acid taurine. UDCA, which is made by gut bacteria, is FDAapproved in the United States for the treatment of certain cholestatic liver diseases. Humans make TUDCA to some extent, but it is found in copious amounts in the bile of bears. TUDCA is a classic inhibitor of endoplasmic reticulum (ER) stress. Reduces ER stress and adipose tissue inflammation in a mouse model of high fat diet-induced obesity. Blocks ER stress-induced NLRP3 inflammasome activation and hepatocyte death. Attenuates amyloid precursor protein processing and amyloid-β deposition in APP/PS1 mouse model.

• 화학적 성질

  Tauroursodeoxycholic acid is an off-White Solid. It is an ambiphilic bile acid. It is mainly found in black bear bile, which is the signature active ingredient in bear bile. It has antispasmodic, anticonvulsant, anti-inflammatory and gallstone dissolving effects.

• 용도

  Tauroursodeoxycholic acid (TUDCA) is a water-soluble bile salt naturally occurring in the body. When bile salts reach the intestines, they can be metabolized by bacteria into ursodeoxycholic acid (UDCA). TUDCA is formed when taurine binds to UDCA. TUDCA is used to treat cholestasis, a condition in which bile fails to flow from the liver to the duodenum. TUDCA, UDCA, and other soluble bile salts can counteract the toxicity of regular bile acids when the latter are backed up in the liver. TUDCA is also used to treat cholesterol gallstones, dissolving them to a size in which they may be passed.

• 정의

  ChEBI: Tauroursodeoxycholic acid is a bile acid taurine conjugate derived from ursoodeoxycholic acid. It has a role as a human metabolite, an anti-inflammatory agent, a neuroprotective agent, an apoptosis inhibitor, a cardioprotective agent and a bone density conservation agent. It derives from an ursodeoxycholic acid. It is a conjugate acid of a tauroursodeoxycholate.

• 부작용

  TUDCA is safe and well-tolerated in patients with liver transplants, liver cirrhosis, and other diseases, but no clinical data exist for treatments longer than 1 year.
  There were no significant differences in adverse events between those receiving standard immunosuppressants versus those receiving bile acids in addition. Other trials in liver cirrhosis (up to 6 months) and ALS (1 year) have also reported that TUDCA is well-tolerated with diarrhea being the only side effect (Elia et al., 2016; Ma et al., 2016; Pan et al., 2013; Crosignani et al., 1996).

• Mode of action

  Tauroursodeoxycholic acid is a bile acid taurine conjugate derived from ursodeoxycholic acid. Bile acid is made by the liver and stored in the gallbladder and helps with digestion. It has a role as a human metabolite, an anti-inflammatory agent, a neuroprotective agent, an apoptosis inhibitor, a cardioprotective agent and a bone density conservation agent. TUDCA is found in small quantities in human bile but at a higher concentration in the bile of black bears, which is the signature active ingredient in bear bile. It demonstrates anti-apoptotic activity in rodent models of tauopathy, Huntington's disease, ischemic brain injury, and retinal disorders.
