Michellamine is an atropisomeric alkaloid which has been found to be a strong anti-HIV viral replication inhibitor. It was discovered in the leaves of the Ancistrocladus korupensis which is a member of the Triphyophyllum peltatum found in Cameroon. There are 3 michellamines represented as A, B, and C, however, Michellamine B is the most active against the NID-DZ strain of HIV-2.
