Macroline-sarpagine and macroline-pleiocarpamine bisindole alkaloids from Alstonia angustifolia.
Nine bisindole alkaloids, comprising four belonging to the macroline-sarpagine group, and five belonging to the macroline-pleiocarpamine group, were isolated from the stem-bark extracts of Alstonia angustifolia (Apocynacea). Their structures were established using NMR and MS analyses.
متن کاملOxidized derivatives of macroline, sarpagine, and pleiocarpamine alkaloids from Alstonia angustifolia.
A total of 20 new indole alkaloids comprising mainly oxidized derivatives of macroline- (including alstofonidine, a macroline indole incorporating a butyrolactone ring-F), pleiocarpamine-, and sarpagine-type alkaloids were isolated from the bark and leaf extracts of Alstonia angustifolia. The structures and relative configurations of these alkaloids were determined using NMR and MS analyses and...
متن کاملMonoterpenoid indole alkaloids from Alstonia yunnanensis and their cytotoxic and anti-inflammatory activities.
The 80% ethanol extract of Alstonia yunnanensis afforded five new monoterpenoid indole alkaloids: 11-hydroxy-6,7-epoxy-8-oxo-vincadifformine (1), 14-chloro-15-hydroxy- vincadifformine (2), perakine N(4)-oxide (3), raucaffrinoline N(4)-oxide (4), and vinorine N(1),N(4)-dioxide (5), together with three known compounds: 11-methoxy-6,7-epoxy-8-oxo- vincadifformine (6), vinorine N(4)-oxide (7) and v...
متن کاملMonoterpenoid indole alkaloids from Alstonia rupestris with cytotoxic, anti-inflammatory and antifungal activities.
Phytochemical investigation of the 70% EtOH extract of the leaves of Alstonia scholaris afforded seven new monoterpenoid indole alkaloids: scholarisins I-VII (1-7), and three known compounds: (3R,5S,7R,15R,16R,19E)-scholarisine F (8), 3-epi-dihydro- corymine (9), and (E)-16-formyl-5α-methoxystrictamine (10). Structural elucidation of all the compounds was accomplished by spectral methods such a...
متن کاملBuxus alkaloids. XIV.* Alkaloids from Buxus sempervirens var. angustifolia WEST
Various species of common box (Buxus) are cultivated in the Arboretum of the Slovak Academy of Sciences in Mlyňany under the same soil and climatic conditions; consequently, the examination of alkaloids produced by those plants is of chemotaxonomical importance. From this locality we investigated so far alkaloids from Buxus sempervirens L.[l,2], B. microphylla SIEB, et ZUCC. var. sinica REHD. e...
