Meroterpenes from Cystoseira usneoides

Two new meroterpenes have been isolated from the brown seaweed Cystoseira usneoides usneoidone E and usneoidone Z. Their structures were established mainly by means of 2D NMR experiments: 1H/ 1H (COSY) and 1H/ 13C one bond and long range (HCCORR) correlations. Both compounds exhibit antitumoural and...

Zusammenfassung:Two new meroterpenes have been isolated from the brown seaweed Cystoseira usneoides usneoidone E and usneoidone Z. Their structures were established mainly by means of 2D NMR experiments: 1H/ 1H (COSY) and 1H/ 13C one bond and long range (HCCORR) correlations. Both compounds exhibit antitumoural and antiviral activities.
