A new aromadendrane sesquiterpene, allo-aromadendrane-10alpha, 14-diol (3), was isolated from Chisocheton penduliflorus (Meliaceae), along with two known sesquiterpenes: allo-aromadendrane-10beta, 14-diol (2) and allo-aromadendrane-10beta, 13, 14-triol (7). Six dammarane triterpenoids, including
A new limonoid, pentandricine (1), along with three known limonoids, ceramicine B (2), 6-de(acetyloxy)-23-oxochisocheton (3), 6-de(acetyloxy)-23-oxo-7-O-deacetylchisocheton (4), have been isolated from the stembark of Chisocheton pentandrus. The chemical structures of the new compound were
In continuation of our interest towards the elucidation of apoptotic pathways of cytotoxic phytocompounds, we have embarked upon a study on the anticancer effects of 7α-hydroxy-β-sitosterol (CT1), a rare natural phytosterol oxide isolated from Chisocheton tomentosus. CT1 was found to be cytotoxic on
Five limonoids isolated from the seeds of Chisocheton siamensis were tested for their antimalarial activity against Plasmodium falciparum, antimycobacterial activity against Mycobacterium tuberculosis and cytotoxic activity against NCI-H187 (human small cell lung cancer), KB (oral human epidermal
