A unique heterodimeric naphthylisoquinoline alkaloid, korundamine A (2), comprised of two different monomeric biaryl halves, has been isolated from the Cameroonian tropical liana Ancistrocladus korupensis. Korundamine A is the first “hybrid” dime

Using bioassay-guided fractionation, dioncophylline A [1] was isolated from the leaves and twigs of the tropical liana Ancistrocladus letestui Pelligr. Dioncophylline A was previously known from Triphyophyllum peltatum and A. abbreviatus. The in vitr

The circular dichroic behavior of the michellamines, dimeric naphthylisoquinoline alkaloids, was investigated. Due to the molecular size and conformational flexibility, which makes direct calculations of the CD spectra very difficult, and because of
