Hyperforin (dicyclohexylammonium salt) (Synonyms: Hyp-DCHA, Hyperforin-DCHA)

Hyperforin is a natural activator of the steroid X receptor (active at 0.1 to 0.5 µg/ml) and inhibitor of several cytochrome P450 (CYP) isoforms (IC50 = 10 µg/ml for CYP2D6).[1],[2] It can also inhibit microsomal prostaglandin E2 synthase-1 (mPGES-1; IC50 = 1 µM), 5-lipoxygenase activating protein, and sirtuins.[3],[4],[5]
