New compounds include eight dihydrodibenzoxepins (1-8), a dihydrobenzofuran (9), a novel spirochromane-2,1′-hexenedione (10), and a new bibenzyl (11). Antimycobacterial, antimalarial, antifungal, cytotoxic, and anti-inflammatory activities of the isolated compounds are reported, and biosynthetic pathways of these compounds are also discussed. © 2007 American Chemical Society and American Society of Pharmacognosy.Mahidol UniversityAgricultural and Biological SciencesChemistryPharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1021/np070010e
