Abstract
A new 2-arylbenzofuran derivative, (+)-dimethylsmoracin O (1 ), and three new Diels-Alder type adducts, mesozygins A–C (2 –4 ), in addition to eight known compounds, artonin I (5 ), chalcomaracin (6 ), norartocarpetin (7 ), moracin L (8 ), mulberrofuran F (9 ), moracin M (10 ), moracin C (11 ), and morachalcone A (12 ), were isolated from the leaves of Morus mesozygia Stapf. Structures were elucidated by spectroscopic data analyses. Compounds 2 –7 displayed a potent phosphodiesterase I inhibitory activity.
Key words
Morus mesozygia
- Moraceae - Diels-Alder adducts - (+)-dimethylsmoracin O - mesozygins A–C - phosphodiesterase
