Tauroursodeoxycholic Acid Powder

Tauroursodeoxycholic Acid Powder is the main active component of bear bile and also the main component of artificially synthesized bear bile. It is a conjugated bile acid widely present in human and various animal bile and has multiple physiological and pharmacological effects. This drug and its preparations have had twenty years of clinical experience on the market abroad. It is mainly used for steroidal gallbladder stones and cholestatic liver diseases (such as Primary biliary cirrhosis, bile reflux gastritis, autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), chronic hepatitis (hepatitis B, hepatitis C, etc.), alcoholic fatty liver disease, non-alcoholic fatty liver disease, drug-induced liver damage, prevention and treatment complications before and after liver transplantation, etc.

Sodium ursodeoxycholate, also known as tauroursodeoxycholic acid or tauroursodeoxycholic acid, has the chemical name 3α, 7β -dihydroxycholanyl-n-taurine. It is mainly found in the bile of black bears and is a characteristic effective component in bear bile. It has the functions of antispasmodic, anticonvulsant, anti-inflammatory and cholestolysis, etc. The modern synthetic drug taurodeoxycholic acid is a conjugative bile acid formed by the shrinkage of the shuttle group of ursodeoxycholic acid and the ammonia group of taurine.

Taurosodeoxycholic acid capsules from abroad have been launched on the market. They were approved for sale in China as imported drugs in 2007. Clinically, they are mainly used to treat gallbladder cholesterol stones, primary sclerosing cholangitis, primary biliary cirrhosis and chronic hepatitis C virus, etc. At present, there is no drug registration for taurosodeoxycholic acid raw materials and their preparations in China.

Sodium ursodeoxycholate is a natural bile acid isolated from bear bile. It is a chemical agent and exists in bile in the body in combination with taurine. It is a hydrophilic bile acid and a cholesterol stone dissolving agent. It can reduce the liver's secretion of cholesterol, lower the saturation of cholesterol in bile, promote the secretion of bile acids, increase the solubility of cholesterol in bile, dissolve cholesterol stones or prevent the formation of stones. It can increase the secretion of bile, relax the sphincter of the bile duct opening and produce a choleretic effect, which is conducive to the excretion of stones. This product cannot dissolve other types of gallstones. It is applicable to the treatment of cholesterol stones, hyperlipidemia, bile secretion disorders, primary biliary cirrhosis, chronic hepatitis, bile reflux gastritis and the prevention of acute rejection and reaction after liver transplantation. The stone-dissolving effect of this product is slightly weaker than that of chenodeoxycholic acid.

Taurosodeoxycholic acid has antispasmodic, anticonvulsant, anti-inflammatory and cholelitic effects. It is mainly used in clinical practice to treat gallbladder cholesterol stones, primary sclerosing cholangitis, primary biliary cirrhosis and chronic hepatitis C virus, etc.

Biochemical research Lipase accelerator Anion remover, used for dissolving proteins; Preparation of bacterial culture medium (Intestinal bacterial culture and isolation)

Used for content determination/identification/pharmacological experiments, etc.

Tauroursodeoxycholate (TUDcA) suppresses both viability and migration of vascular smooth muscle cells (VsMCs) throughinhibition of ERK phosphorylation, by induction of mitogen-activated protein kinase phosphatase-1 (MKP-1) via PKCa.
Tauroursodeoxycholate inhibits both the proliferation and migration of VSMCs via inhibition of ERK, through Ca 2+dependent PKCa translocation. Tauroursodeoxycholate prevents platelet-derived growth factor (PDGF) and vascular injury.induced MlMP-9 expression, The knock-down of MKP-1 using specific si-RNA restores the reduced VSMC viability byTauroursodeoxycholate (200 yl), which suggests that anti-proliferative effect of Tauroursodeoxycholate depended on the
MKP_1 expression.
