Vinorine is a monoterpenoid indole alkaloid, a type of natural alkaloids. Growing reports exhibited the numerous pharmacology activities of vinorine such as anti-inflammation, anti-bacterial and anti-tumor. In this study, the effect of vinorine injection (7.5, 15 and 30 mg/kg) on motor function,
One new indole alkaloid, reflexin A (1), and two known indoles, macusine B (2) and vinorine (3), were isolated from the bark of Rauvolfia reflexa. Their structures were elucidated by 1D and 2D NMR, UV, IR, and MS spectroscopic analyses. Compound 1 displayed anticancer activity against HCT-116 colon
Vinorine synthase is an acetyltransferase that occupies a central role in the biosynthesis of the antiarrhythmic monoterpenoid indole alkaloid ajmaline in the plant Rauvolfia. Vinorine synthase belongs to the benzylalcohol acetyl-, anthocyanin-O-hydroxy-cinnamoyl-,
A chemical investigation of the 80% EtOH extract of the aerial plant of Alstonia rupestris afforded four new monoterpenoid indole alkaloids, 6,7-epoxy-8-oxo-vincadifformine (1), 11-acetyl-6,7-epoxy-8-oxo-vincadifformine (2), 11-hydroxy-14-chloro-15-hydroxy-vincadifformine (3), and perakine
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
