[Acridine-alkaloids from callus cultures of Ruta graveolens L].
Rutacridone, 1-hydroxy-A-methylacridone, and l-hydroxy-3-methoxy-A-methylacridone have been isolated for the first time from callus cultures, which had been obtained from meristematic stem cells of Ruta graveolens L. The alkaloids were identified by co-chromatography with authentic compounds, by IR spectra, and by electronic spectra before and after addition of A1C13 . The use of the bathochrom...
متن کاملBiosynthesis of Acridone Alkaloids. A Cell-Free System from Ruta graveolens Cell Suspension Cultures
Ruta graveolens, Suspension Cultures, Cell-Free System, Acridone Biosynthesis, 1,3-DihydroxyN-methylacridone A cell-free extract of Ruta graveolens cell suspension cultures, strain R-20, was prepared which synthesizes 1,3-dihydroxy-N-methylacridone from N-methylanthranilic acid and malonylcoenzyme A. The reaction is strongly dependent on the presence of ATP. After adding of coenzyme A to the as...
متن کاملAntiproliferative constituents in plants 14. Coumarins and acridone alkaloids from Boenninghausenia japonica NAKAI.
The MeOH extracts of the ground part and the root of Boenninghausenia japonica NAKAI showed inhibitory activity against tumor cell growth. Fractionation of the extracts has resulted in isolation of 1,3-dihydroxy-4-(2'-hydroxy-3'-hydroxymethyl-3',4'-epoxy-butyl)-N-methylacridone, 1,3-dihydroxy-4-[(Z)-3'-hydroxy-3'-methyl-buten-1'-yl]-N-methylacridone, 3-(1',1'-dimethylallyl)-7-hydroxy-8-methoxy-...
متن کاملBioactive Alkaloids from South American Psychotria and Related Species
Many important molecules have been discovered from tropical and sub-tropical plant biodiversity. However, the largest part of the chemical profile of such biodiversity remains unknown. Combining ethnopharmacological and chemotaxonomical investigation can be a good strategy in bioactive compound discovery. South American Psychotria species studied by this approach proved to be a rich source of n...
