Tauro-β-muricholic acid (TβMCA) is an orally active trihydroxylated bile acid and a competitive, reversible FXR antagonist (IC₅₀=40 μM). Tauro-β-muricholic acid inhibits bile acid-induced hepatocyte apoptosis by maintaining mitochondrial membrane potential, while simultaneously inhibiting intestinal FXR signaling, affecting bile acid synthesis, hepatic lipid metabolism, and insulin sensitivity. Accumulation of tauro-β-muricholic acid disrupts metabolic homeostasis, promoting cancer stem cell proliferation and tumor progression. The mechanisms of tauro-β-muricholic acid involve two aspects: first, inhibiting the translocation of the pro-apoptotic protein Bax to mitochondria and maintaining mitochondrial membrane potential (MMP); and second, blocking the FXR signaling pathway to regulate bile acid metabolism, reduce serum ceramide production, and downregulate the hepatic SREBP1C/CIDEA pathway. Tauro-β-muricholic acid possesses anti-hepatocyte apoptosis, bile acid homeostasis regulation, and liver fat accumulation reduction properties, and also functions as a biomarker, making it useful in the study of diseases such as bile acid metabolism disorders, non-alcoholic fatty liver disease, colorectal cancer, and liver fibrosis.

Notoginsenoside Ft1 is an orally active bioactive saponin. Notoginsenoside Ft1 inhibits the PI3K/AKT/mTOR signaling pathway, activates the p38 MAPK and ERK1/2 signaling pathways, and increases the proportion of CD8⁺ T cells, thereby inducing apoptosis and lysosomal cell death in various cancer cells, and promoting angiogenesis. Notoginsenoside Ft1 causes vasodilation by activating glucocorticoid receptors (GR) and estrogen receptor beta (ERβ) in endothelial cells. Notoginsenoside Ft1 increases intracellular Ca²⁺ accumulation, reduces cAMP levels by activating a signaling network mediated through P2Y₁₂ receptors, and promotes platelet aggregation, thereby exerting a procoagulant effect. Notoginsenoside Ft1 inhibits ferroptosis (ferroptosis) in renal tubular epithelial cells by activating the TGR5 receptor, thereby demonstrating a renal protective effect.
