Taurochenodeoxycholic Acid CAS 516-35-8

1. Taurochenodeoxycholic acid (TCDCA) is a primary bioactive bile acid found in animal bile, where it interacts with intestinal microbiota during enterohepatic circulation, playing a crucial role in nutrient absorption, metabolism regulation, and maintaining dynamic balance in the body .
2. The compound exhibits a wide range of pharmacological effects including hepatoprotective, nephroprotective, cardioprotective, and neuroprotective activities; Taurochenodeoxycholic acid CAS 516-35-8 promotes bile secretion, dissolves gallstones, relieves cough and dyspnea, and helps regulate intestinal function and blood glucose levels .
3. TCDCA functions as an endogenous antagonist of the farnesoid X receptor (FXR) , and research suggests FXR activation by TCDCA can acutely stimulate insulin secretion in pancreatic β-cells via K(ATP) channel inhibition .
4. Researchers utilize Taurochenodeoxycholic acid CAS 516-35-8 to study its anticarcinogenic potential and therapeutic applications in biliary carcinogenesis, where it may modulate cyclooxygenase-2 (COX-2) activity and prostaglandin production through effects on cytosolic phospholipase A2 (cPLA2) expression .

1. Taurochenodeoxycholic acid must be stored in a tightly sealed container at -20°C for long-term stability (up to 3 years) or at 4°C for up to 2 years; solutions should be stored at -80°C for up to 6 months or -20°C for 1 month .
2. Taurochenodeoxycholic acid CAS 516-35-8 contains a pharmaceutically active ingredient that should only be handled by trained personnel, as it is considered moderately to severely irritating to skin and eyes ; GHS hazard classifications include R28 (very toxic if swallowed), R38 (irritating to skin), and R41 (risk of serious damage to eyes) .
3. Personnel must wear NIOSH/MSHA-approved respirators, chemical-resistant rubber gloves, chemical safety goggles with side-shields, and impervious protective clothing when handling this substance, ensuring adequate ventilation and avoiding formation of dust and aerosols .
4. Taurochenodeoxycholic acid CAS 516-35-8 is stable under recommended storage conditions but should be protected from light and heat, kept away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases ; it is considered non-hazardous for transport (DOT, IATA, IMDG) .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including self-contained breathing apparatus, chemical-resistant rubber gloves, and chemical safety goggles when taurochenodeoxycholic acid is released .
2. Collect Taurochenodeoxycholic acid CAS 516-35-8 spills by absorbing with finely-powdered liquid-binding materials such as diatomite or universal binders; for solid spills, sweep or vacuum without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Decontaminate surfaces and equipment by scrubbing with alcohol, and prevent the product from entering drains or water courses as discharge into the environment must be avoided .
4. Dispose of collected material in accordance with prevailing country, federal, state, and local environmental regulations through licensed chemical destruction or controlled incineration .

1. Taurochenodeoxycholic acid is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) during thermal decomposition .
2. Use Taurochenodeoxycholic acid CAS 516-35-8 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product, selecting appropriate extinguishing media based on surrounding environment .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning taurochenodeoxycholic acid due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may Taurochenodeoxycholic acid CAS 516-35-8 emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination and pollution .
