Abstract

Three new cyathane diterpenes erinacines T-V (1-3), and two known cyathane diterpenes erinacine A (4) and erinacine P (5) were isolated from the liquid cultures of Hericium erinaceus. The structures of 1-3 were determined by extensive spectroscopic analysis. All isolated compounds were evaluated for the cytotoxicity, and neurite-promoting activities using PC12 cell line. Compounds 1-3, and 5 exhibited pronounced neurite outgrowth-promoting effects on PC12 cells in the range of 2.5-10 μM. Compound 4 showed weak cytotoxicity against PC12 cells with IC50 of 73.7 μM.
