Abstract:

One new meroterpenoid, named hericenone K (11), along with 10 known compounds (1-10), ergosterol peroxide (1), cerevisterol (2), 3β,5α,9α-trihydroxy-ergosta-7,22-dien-6-one (3), inoterpene A (4), astradoric acid C (5), betulin (6), oleanolic acid (7), ursolic acid (8), hemisceramide (9), and 3,4-dihydro-5-methoxy-2-methyl-2-(4'-methyl-2'-oxo-3'-pentenyl)-9(7H)-oxo-2H-furo[3,4-h]benzopyran (10), was isolated from the fruiting bodies of the mushroom Hericium erinaceus. Their structures were characterized on the basis of spectroscopic methods, as well as through comparison with previously reported data. Compounds 3-6, 8, and 9 were isolated from Hericium species for the first time. Compounds 10 and 11 was suggested to beracemic by the CD spectrum data and specific rotations, which ware resolved by chiral HPLC into respective enantiomers. Compounds 1-3, (±)-10, (-)-10 and (+)-10 in the presence of NGF (20ng/mL) exerted a significant increase in neurite-bearing cells.
