title: Diterpenoids and a diarylheptanoid from Hedychium coronarium with significant anti-angiogenic and cytotoxic activities.
abstract: Two new labdane diterpenoids, namely hedycoronals A and B (1 and 2, resp.), were isolated from the rhizomes of Hedychium coronarium, together with eight known diterpenoids, 4-11, and a known diarylheptanoid, 3. The structures of 1 and 2 were established by detailed interpretation of their 1D- and 2D-NMR spectra and HR-ESI-MS data. Inhibitory activities against human umbilical vein endothelial cells (HUMECs) proliferation and cytotoxic activities against four cancer cell lines were assessed for all the isolates. Most of these metabolites showed moderate or potent cytotoxic activities against four cancer cell lines. Moreover, compounds 3 and 8 exhibited promising inhibitory activities against HUMECs with the IC(50) values of 6.4 to 3.3 μM.
