Investigation on the cultures of Hypsizygus marmoreus resulted in the isolation of a new viscidane diterpene,8-oxoviscida-3,11(18)-diene-13,14,15,19-tetraol(1)and two new polyacetylenes,(E)-10-(1,1-dimethyl-2-propenyl...Investigation on the cultures of Hypsizygus marmoreus resulted in the isolation of a new viscidane diterpene,8-oxoviscida-3,11(18)-diene-13,14,15,19-tetraol(1)and two new polyacetylenes,(E)-10-(1,1-dimethyl-2-propenyloxy)-2-decene-4,6,8-triyn-1-ol(2)and 10-(1,1-dimethyl-2-propenyloxy)deca-4,6,8-triyn-1-ol(3),together with two known polyacetylenes,(E)-2-decen-4,6,8-triyn-1-ol(4)and 4,6,8-decatriyn-1-ol(5).Their structures were elucidated on the basis of extensive spectroscopic studies.Compound 1 is the first finding of viscidane diterpene in mushrooms.Compounds 1,3 and 5 were tested for cytotoxicity against human tumor cell lines HL-60,SMMC-7721,A-549,MCF-7 and SW-480.None of the compounds showed cytotoxic activity(IC50[40 lM).展开更多
