Biological Activities
Dioncophyllum thollonii is a rare West African liana that serves as a rich source of unique naphthylisoquinoline alkaloids. Among its most significant chemical discoveries is dioncophylline E, a novel compound characterized by an unusual 7,3'-linkage. This specific structural arrangement results in the presence of two configurationally semi-stable atropo-diastereomers due to steric hindrance. Most notably, dioncophylline E exhibits potent antimalarial activity against both chloroquine-sensitive and resistant strains of Plasmodium falciparum. This biological property highlights the significant medicinal potential inherent within this specialized plant species.
Compounds
Dioncophyllum thollonii is a rare West African liana that serves as the natural source of the novel naphthylisoquinoline alkaloid known as dioncophylline E. This unique compound is distinguished by an unusual 7,3'-linkage between its naphthalene and isoquinoline portions. Due to significant steric hindrance at the biaryl axis, dioncophylline E exists as a mixture of two configurationally semi-stable atropo-diastereomers. Beyond its structural complexity, the alkaloid demonstrates promising antimalarial activity against both chloroquine-sensitive and resistant strains of Plasmodium falciparum. The chemical profile of this plant is further enriched by the presence of several other alkaloids previously identified in related species.
Conditions
Dioncophyllum thollonii contains the alkaloid dioncophylline E, which demonstrates significant medicinal potential against various parasites. This plant extract provides moderate antitrypanosomal activity against Trypanosoma brucei rhodesiense. Regarding Trypanosoma cruzi, the plant's effect is characterized as having weak antitrypanosomal activity. Furthermore, it exhibits good antimalarial efficacy against chloroquine-sensitive strains of Plasmodium falciparum. The plant also shows effectiveness against chloroquine-resistant strains of Plasmodium falciparum.
