Five New Meroterpenoids from the Fruiting Bodies of the Basidiomycete Clitocybe clavipes with Cytotoxic Activity
Five new meroterpenoids, clavipols A-B ( - ) with a 12-membered ether ring and clavilactones G-I ( - ) having a 10-membered carbocycle connected to a hydroquinone and an α,β-epoxy/unsaturated lactone, were obtained from the fruiting bodies of the basidiomycete . Their structures were determined by c...

Zusammenfassung: | Five new meroterpenoids, clavipols A-B (
-
) with a 12-membered ether ring and clavilactones G-I (
-
) having a 10-membered carbocycle connected to a hydroquinone and an α,β-epoxy/unsaturated lactone, were obtained from the fruiting bodies of the basidiomycete
. Their structures were determined by comprehensive analysis of their spectroscopic data, and the absolute configuration of
was established by quantum chemical calculations of electronic circular dichroism (ECD). All the isolated compounds (
-
) were tested for their cytotoxic activity against three human tumor cell lines (Hela, SGC-7901, and SHG-44) in vitro after treatment for 48 h. Compound
exhibited moderate cytotoxic activity against Hela and SGC-7901 tumor cell lines, with IC
values of 23.5 and 14.5 µM, respectively. |
