Abstract
A new neolignan, (7 S,8 R)- threo-1′-[3′-hydroxy-7-(4-hydroxy-3,5-dimethoxyphenyl)-8-hydroxymethyl-7,8-dihydrobenzofuran]acrylaldehyde (1), along with 5 known compounds 2-6, were isolated from the fruits of Xanthium strumarium. Their structures were elucidated by extensive spectroscopic methods. All the isolates were evaluated for in vitro cytotoxicity against human cancer cell lines, including human hepatoma cell line (HepG2), human breast cancer cell line (MCF-7), human colon cancer cell line (HCT-116), and human gastric cancer cell line (SGC-7901). Among them, compounds 1 and 3 showed selective cytotoxicity on HepG2 cancer cells with half-maximal inhibitory concentration (IC50) values of 10.2 ± 1.2 and 18.3 ± 1.6 μM, respectively. Moreover, compound 5 also exhibited moderate cytotoxicity against MCF-7 cancer cells with an IC50 value of 20.5 ± 1.3 μM.
