Ancistroealaines A and B, two new bioactive naphthylisoquinolines, and related naphthoic acids from Ancistrocladus ealaensis.
Two new 5,8'-coupled naphthylisoquinoline alkaloids, ancistroealaines A (1) and B (2), eleutherolic acid (3), and two naphthoic acids, ancistronaphthoic acid A (4) and B (5), have been isolated from Ancistrocladus ealaensis. Their structures were determined by spectroscopic, chemical, and chiroptical methods. Ancistroealaine A (1) exhibited activity against Leishmania donovani and Trypanosoma cruzi in vitro.
