Pleurotus cornucopiae (Pleurotaceae) is an edible and medicinal mushroom widely distributed in Korea, China, and Japan. The MeOH extract of the fruiting bodies of P. cornucopiae showed renoprotective effects against cisplatin-induced kidney cell damage. Chemical investigation of the MeOH extract led to the isolation and identification of 12 compounds including noransine (1), uridine (2), uracil (3), (3β, 5α, 6β, 22E, 24S) -ergosta-7, 22-diene-3, 5, 6, 9-tetrol (4), (22E,24S)-ergosta-7,22-diene-3β,5α,6β-triol (5), (22E,24R)-ergosta-8(14),22-diene-3β,5α,6β,7α-tetrol (6), cerebroside B (7), (2R) -N- [(1S, 2R, 3E, 7E) -1- [(β-d-glucopyranosyloxy) methyl] -2-hydroxy-8-methyl-3, 7-heptadecadien-1-yl] -2-hydroxy-heptadecanamide (8), cerebroside D (9), nicotinamide (10), 1,2-bis(hydroxymethyl)-4,5-dimethoxybenzene (11), and benzoic acid (12). Among them, compounds 1 and 11 were isolated as naturally occurring products for the first time, though they were reported as synthetic products in previous papers. All of the compounds (except 8 and 11) abrogated cisplatin-induced LLC-PK1 cell damage in a dose-dependent manner. Of special note, compounds 2, 5, 6, and 12 ameliorated cisplatin-induced nephrotoxicity to 80% of the control value at 10μM. The protective effects of compounds 2, 5, 6, and 12 were mediated via the deactivation of JNK-caspase 3 apoptotic cascade. This study is the first to demonstrate that the chemical constituents of P. cornucopiae display renoprotective effects against anticancer drug-induced damage in kidney cells.
