New quassinoids, delaumonones A (1) and B (2) have been isolated from the bark of Laumoniera bruceadelpha NOOTEBOOM (Simaroubaceae) and the structures were elucidated by 2D NMR analysis and a chemical correlation. Delaumonones showed an antimalarial activ

Short-term in vitro assays for tumor promoters and antitumor promoters (Epstein-Barr virus activation test) were carried out for semisynthetic quassinoids (3-7), which were obtained by esterification of the C-15 OH group of deacetylated isobrucein-B (2).
