Tauro-α-muricholic Acid Sodium Salt is a bile acid released from the liver typically used for cholestasis studies. The mechanism of action of this compound is multifaceted, involving multiple pathways. Studies have demonstrated its ability to activate diverse signaling pathways, such as the nuclear factor kappa B (NF-κB) pathway and the peroxisome proliferator-activated receptor alpha (PPARα) pathway. Additionally, it exerts an influence on the gut microbiota, leading to alterations in the composition and functionality of the microbial community.
