| ancistrolikokine d, a 5,8'-coupled naphthylisoquinoline alkaloid, and related natural products from ancistrocladus likoko. | a new naphthylisoquinoline alkaloid, ancistrolikokine d, and the likewise 5,8'-coupled alkaloid ancistroealaine a, as well as two further, biosynthetically related, but nitrogen-free natural products, ancistronaphthoic acid b and cis-isoshinanolone, have been isolated from ancistrocladus likoko j. leacute;onard (ancistrocladaceae). the 5,8'-coupling of the new alkaloids and of the alkaloids isolated earlier hints at a close phylogenetic relationship of a. likoko to other central african ancistro ... | 2003 | 12560038 |
