Monoterpenoid 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 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 کاملIndole Alkaloids from Chaetomium globosum.
Two new indole alkaloids chaetocochin J (1) and chaetoglobinol A (8), along with chetomin (2), chetoseminudin A (3), cochliodinol (9), and semicochliodinol (10), were isolated from the rice culture of the fungus Chaetomium globosum. Their structures were elucidated by spectral analysis. Three new epipolythiodioxopiperazines, chaetocochins G-I (5-7), were identified by the combination of UPLC an...

متن کاملMacroline, akuammiline, sarpagine, and ajmaline alkaloids from Alstonia macrophylla.
A total of seventeen alkaloids, comprising six macroline (including alstofolinine A, a macroline indole incorporating a butyrolactone ring-E), two ajmaline, one sarpagine, and eight akuammiline alkaloids, were isolated from the stem-bark and leaf extracts of the Malayan Alstonia macrophylla. The structure and relative configurations of these alkaloids were established using NMR, MS and in sever...
