| Abstract |
Six new polyketide-derived oxaphenalenone dimers, talaromycesone C (1) and macrosporusones A-E (2–6), together with eight known analogs, were isolated from the mycelium of the fungus Talaromyces macrosporus KKU-1NK8. Their structures were established based on their spectroscopic data and MS. The absolute confgurations of new compounds 1–6 were determined by ECD analyses. Compounds 3 and 8 exhibited antimalarial
activity against Plasmodium falciparum. Compound 3 showed activity against NCI-H187 cells, while compound 8
displayed activity against KB, MCF-7 and NCI-H187 cell lines. In addition, compound 11 showed antibacterial activity against Bacillus cereus, Staphylococcus aureus and MRSA. |
