Two new prenylated chromones, artoheterophines A (1) and B (2), five known prenylated chromones (3-7), as well as five known biogenetically related prenylated flavonoids (8-12) were isolated and characterized from the stems and leaves of A. heterophyllus. Their chemical structures were unambiguously determined through com-prehensive spectral data analyses. The antiproliferative and anti-inflammatory effects of all these isolated pre-nylated chromones and flavonoids were evaluated in vitro. As a result, compounds 1-12 showed notable in-hibitory effects against various human cancer cell lines with IC50 values ranging from 0.36 +/- 0.02 to 22.09 +/- 0.16 mu M. Meanwhile, compounds 1-12 exhibited significant inhibitory activities on nitric oxide (NO) production holding IC50 values in the range of 0.48 +/- 0.05-19.87 +/- 0.21 mu M. These research results suggest that the isolation and characterization of these prenylated chromones (1-7) and flavonoids (8-12) holding significant antiproliferative and anti-inflammatory activities could be significant to the discovery and devel-opment of new natural anti-tumor and anti-inflammatory drugs. The findings also provides a phytochemical evidence for further development and utilization of the stems and leaves of A. heterophyllus in health and pharmaceutical products.
