Used in research for its potential anti-cancer properties, particularly in overcoming multidrug resistance in tumor cells. It modulates P-glycoprotein, a key efflux pump involved in resistance to chemotherapy, thereby enhancing the intracellular accumulation of anti-cancer drugs. Also investigated for anti-inflammatory and neuroprotective effects in preclinical studies. Its complex diterpene structure makes it a candidate for structure-activity relationship studies in drug development.
