Four new naphthylisoquinoline alkaloids, ancistrocongolines A-D (4-7) were isolated from Ancistrocladus congolensis, along with the known compound korupensamine A (8). Structural elucidation was achieved by chemical, spectroscopic, and chiroptical methods. Their biological activities against the pathogens of malaria, Leishmaniasis, Chagas disease, and African sleeping sickness were evaluated.
