Guggulsterone - a potent bioactive phytosteroid: synthesis, structural modification, and its improved bioactivities.

Guggulsterone is a phytosteroid derived from the oleo-gum resin of the critically endangered plant . This molecule has attracted increasing attention due to its excellent biochemistry potential and the compound has consequently been evaluated in clinical trials. With a low concentration in natural resources but wide medicinal and therapeutic value, chemists have developed several synthetic routes for guggulsterone starting from various steroid precursors.
