Chemical constituents from fruiting bodies of Basidiomycete Perenniporia subacida

Four new aromatic abietane diterpenoids and two new benzene derivatives, namely perenacidins A-F (1-6), have been isolated from the fruiting bodies of Basidiomycete Perenniporia subacida. The structures were elucidated by means of extensive spectroscopic methods and computational ECD method. The antifungal activities against Canidia albicans and the cytotoxic activities against four cancer cell lines (including K-562, A-549, SMMC-7721, MCF-7) were evaluated in vitro.

Chain terpenoids isolated from cultures of basidiomycete Phellinus sp.

Two new sesquiterpenoids (phellinuins H and I), together with five known compounds, were isolated from cultures of mushroom Phellinus sp. Their structures were elucidated based on comparison of nuclear magnetic resonance and MS data and those reported in the literature. All of these compounds were tested for cytotoxicity against five cancer cell lines (HL-60, SMMC-721, A-549, MCF-7, and SW-480).

Brasilane sesquiterpenoids and alkane derivatives from cultures of the basidiomycete Coltricia sideroides

Three new brasilane-type sesquiterpenoids, brasilanes A-C (1-3), together with two new alkane derivatives, colisiderin A (4) and 7(E),9(E)-undecandiene-2,4,5-triol (5), were isolated from cultures of the basidiomycete Coltricia sideroides. Their structures were elucidated by NMR and MS data analyses. The absolute configuration of 4 was determined by TDDFT ECD calculations while brasilane-type sesquiterpenoids were isolated from cultures of mushroom for the first time. Compounds 2 and 4 showed weak cytotoxicities against HL-60 and SW480, respectively.
