Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine
Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals

Further alkaloids of Alstonia muelleriana [PDF]
Phytochemistry, 1973 Abstract Five further alkaloids, des- N ′ a -methylanhydromacralstonine, quebrachidine, vinervinine, pleiocarpamine, and 2,7-dihydropleiocarpamine, have been isolated from Alstonia muelleriana bark. Phytochemical problems in the genus Alstonia are considered, especially with reference to the ‘macroline-derived’ indole and bis-indole alkaloids.
