生物活性

Geniposidic acid is an orally active FXR modulator and SIRT6 activator. Geniposidic acid binds to the Ser332 and His447 sites on the FXR ligand-binding domain, thereby driving nuclear translocation, coactivator recruitment, and transcription of downstream bile acid and cholesterol metabolism-related genes. Geniposidic acid improves metabolic dysfunction-related fatty liver disease by activating the SIRT6 signaling pathway. Geniposidic acid inhibits inflammation and modulates gut microbiota to alleviate colitis. Geniposidic acid can be used in research on drug-induced liver injury, inflammatory bowel disease, metabolic dysfunction-related fatty liver disease, and metabolic dysfunction-related steatohepatitis[1][2][3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
