Abstract

Chemical investigation of the stem bark of Anthocephalus cadamba has resulted in the isolation of anthocephaline (1), a new indole alkaloid, along with strictosamide (2), vincosamide (3) and cadambine (4). The structures of the isolated alkaloids (1-4) were established by detailed 2D NMR spectral analysis. Cadambine (4) exhibited potent DNA topoisomerase IB inhibitory activity.
