Two new sesquiterpene coumarins, designated 5'-acetoxy-8'-hydroxyumbelliprenin (1) and 10'R-acetoxy-11'-hydroxyumbelliprenin (2), and a new diterpene, 15-hydroxy-6-en-dehydroabietic acid (3), along with 27 known compounds, were isolated from a CHCl(3)-soluble extract of Ferula assa-foetida through bioassay-guided fractionation. The structures of the new metabolites 1-3 were identified by spectroscopic data interpretation and by the Mosher ester method. Compounds 4 and 6-13 showed greater potency against influenza A virus (H(1)N(1)) (IC(50) 0.26-0.86 microg/mL) than amantadine (IC(50) 0.92 microg/mL), and 11 exhibited the best potency (IC(50) 0.51, 2.6, and 3.4 microg/mL) of these compounds against the HepG2, Hep3B, and MCF-7 cancer cell lines, respectively.
