Influenza A (H(1)N(1)) Antiviral and Cytotoxic Agents from Ferula assa-foetida.

30 Aug 2009 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 ... Read more...

Cytotoxic constituents of Soymida febrifuga from Myanmar.

30 Aug 2009 The 70% ethanol extract of Soymida febrifuga was found to kill PANC-1 human pancreatic cancer cells preferentially under nutrition-deprived conditions at a concentration of 10 microg/mL. Phytochemical investigation led to the isolation of 27 ... Read more...
