Researchers identified 10 secondary metabolites from the edible mushroom Fr. Pilat, including a new lanostane triterpenoid. The neuroprotective function of all steroidal metabolites was investigated, and results showed that 2α-HI exhibited the most significant neuroprotective activity. The Nrf2 and BDNF/TrkB/ERK/CREB signaling pathway mediated the neuroprotective effects of 2α-HI against oxidative stress and apoptosis. The neuroprotection of 2α-HI was also verified in zebrafish. These findings suggest that Fr. Pilat could be a potential dietary supplement to ameliorate neurodegenerative diseases.
