MA, Wei et al. Cytotoxic and Anti-inflammatory Constituents from Juncus effusus. J. Mex. Chem. Soc [online]. 2016, vol.60, n.2, pp.83-88. ISSN 1870-249X.

A new sesquilignan effususin E (1) and a new long chain fatty enamide effususin F (2), together with eight known compounds were isolated from the medullae of Juncus effusus. The structures of 1 and 2 were elucidated by detailed spectroscopic analysis including 1H and 13C NMR, COSY, HSQC, HMBC, and HRMS, while the structures of the known compounds were deduced from comparison of their spectral data with those in the literature. The new compounds 1 and 2 were evaluated against five human cancer cell lines (SHSY-5Y, SMMC-7721, HepG-2, Hela, and MCF-7) by CCK-8 assay, but only 1 exhibited weak cytotoxic activity against SMMC-7721 with IC50 value of 57.5 μm. Inhibitory effects of 1 and 2 on nitric oxide (NO) production in lipopolysaccharide-induced RAW264.7 macrophages were also evaluated, and they were found to exhibit good inhibitory activities with IC50 values of 8.59 and 13.73 μm, respectively.
