Anthocephaline, a new indole alkaloid and cadambine, a potent inhibitor of DNA topoisomerase IB of Leishmania donovani (LdTOP1LS), isolated from Anthocephalus cadamba
- Nat Prod Commun. 2015 Feb;10(2):297-9.
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.
