Ancistrocladus korupensis is a species of liana endemic to southwestern Cameroon and the neighbouring regions of Nigeria.

When the sapling is three or four metres tall, one shoot develops into an aerial, hooked stem with alternate long leaves, which quests upward in search of a host.

The flowers have yellowish-green sepals, pinkish or yellowish petals, ten stamens in two whorls and three styles.

[3] Mature leaves of Ancistrocladus korupensis contain michellamine A, B and C, atropisomeric alkaloids which have been found to inhibit HIV viral replication.

[6] The National Cancer Institute considers michellamine B to have considerable potential for use against HIV because of its particularly effective mode of action.
