ibogamine/tabernaemontana

Several species from the Apocynaceae family, such as Tabernanthe iboga, Voacanga africana, and many Tabernaemontana species, produce ibogan type alkaloids, some of which present antiaddictive properties. In this study, we used gas chromatography/mass spectrometry (GC/MS) to examine the efficiency of

Three new monoterpene indole alkaloids, 3α-hydroxymethyl-ibogamine (1), 3α-acetatemethoxyl-ibogamine (2), 16α-hydroxyl-ibogamine (3) together with six known alkaloids were isolated from the branches and leaves of Tabernaemontana divaricata (Apocynaceae). The structures of these alkaloids were

Virtual Screening and Molecular Docking analysis for Tabernaemontana divaricata derived 66 Law Molecular Weight Compounds (LMW) was conducted and to identified and predicted novel molecules as a inhibitor of Streptococcus pneumonia. The investigation has revealed several compounds with optimum

Active plant metabolites have been used as prototype drugs. In this context, Tabernaemontana catharinensis (Apocynaceae) has been highlighted because of the presence of active indole alkaloids. Thus, this study aims the bio-guided search of T. catharinensis cytotoxic alkaloids. The chemical

Ten indole alkaloids from the chloroform extract of stalk of Tabernaemontana australis (Muell. Arg) Miers were tentatively identified by GC-MS, viz., coronaridine (1), voacangine (2), voacangine hydroxyindolenine (3), rupicoline (4), ibogamine (5), ibogaine (6), ibogaline (7), desethyl-voacangine

Bioassay-directed fractionation of the alkaloid portion of a CH(2)Cl(2)-MeOH extract of Tabernaemontana calcarea resulted in the isolation of the three new cytotoxic indole alkaloids, 1-3, and the 12 known alkaloids voacangine (4), isovoacangine (5), coronaridine (6), 11-hydroxycoronaridine (7),

The isolation and structure elucidation of the three new bisindole alkaloids, gabunamine, tabernamine, and 19,20-epoxyconoduramine, from Tabernaemontana johnstonii stem bark are described. The isolation of the seven known alkaloids, conodurine, conoduramine, gabunine, isovacangine, ibogamine,

Ibogaine and other ibogan type alkaloids present anti-addictive effects against several drugs of abuse and occur in different species of the Apocynaceae family. In this work, we used gas chromatography-mass spectrometry (GC/MS) and principal component analysis (PCA) in order to compare the alkaloid
