DETAILS

Sigma Aldrich - G4923

Biochem/physiol Actions
Naturally occuring bioactive plant sterol isolated from the gum resin of guggul (Commiphora wightii). Antihyperlipidemic. Induces the expression of human CYP3A.1. Guggulsterone potently reverses multi-drug resistance in a number of human cancer cell lines, extending the efficacy of chemotherapy.2

Sigma Aldrich - G5168

Biochem/physiol Actions
(Z)-Guggulsterone is a natural product that lowers cholesterol due to its function as an antagonist ligand for the bile acid receptor. (Z)-Guggulsterone is a nuclear hormone receptor that regulates the transcription of several genes involved in cholesterol metabolism and plays a role in cholesterol level regulation. (Z)-Guggulsterone is also a selective farnesoid X receptor (FXR) modulator.
