Ganoderic acid DM is a triterpenoid that has been found inG. lucidumand has diverse biological activities.^1,2,3It inhibits 5α-reductase and HMG-CoA reductase (IC₅₀s = 10.6 and 9.5 µM, respectively) and binds to the ligand-binding domain of the androgen receptor in a fluorescence polarization assay.^1,2Ganoderic acid suppresses osteoclastogenesis of RAW 264.7 cells when used at a concentration of 12.5 µM and is cytotoxic to K562 leukemia and PC3 prostate cancer cells (IC₅₀s = 18.8 and 81.6 µM, respectively). It reduces ear edema induced by phorbol 12-myristate 13-acetate in mice (ID₅₀= 0.08 mg/ear).³
