Dermatolactone, a cytotoxic fungal sesquiterpene with a novel skeleton

Omphalotins E–I, Five Oxidatively Modified Nematicidal Cyclopeptides from Omphalotus olearius

“…[1,3,13] The medium was composed of yeast extract (4 g L -1 , Hartge Ingredients, Hamburg, Germany), malt extract (10 g L -1 , Difco Laboratories, Detroit, USA), glucose (4 g L -1 , Stockmeier, Herford, Germany). Cultures were harvested after 7 d, when the concentration of the omphalotins (analyzed by HPLC-MS) had reached its maximum.…”

“…[1,13] Cytotoxicity was assayed as described previously. Colo-320 cells (DSMZ ACC 144) and L-1210 cells (DSMZ ACC 123) were grown in RPMI 1640 medium (Invitrogen).…”

Studies on Biocontrol of Air-borne Plant Disease by a Filamentous Fungus Producing Antifungal Volatiles

“…Although these compounds are known to be nematicidal 8 , this is the first report of antifungal activity for 5-(4-pentenyl)-2-furaldehyde 13 . The antifungal activity of PTF produced by filamentous fungi has not been known with the exception of antifungal activity against Nematospora coryli 14 . Culture experiments revealed that synthesized PTF had antifungal activity against three other pathogens: Fusarium oxysporum f. sp.…”

Five new 5,6-seco-tremulane sesquiterpenoids from the basidiomycete Conocybe siliginea

“…1 So far, 5,6-seco-tremulane sesquiterpenoids have been found limited to basidiomycete C. siliginea [1][2][3] and Irepex lacteus, 9 and only dermatolactone showed cytotoxic activity and weak antimicrobial activity. 9 This paper describes the isolation and structure elucidation of five new 5,6-seco-tremulane sesquiterpenoids.…”
