Pyrrolizidine alkaloids from Liparis nervosa with antitumor activity by modulation of autophagy and apoptosis.[Pubmed: 29980107]
Seven pyrrolizidine alkaloids, nervosine X-XV and nervosine VII N-oxide, together with a reaction product, namely chloride-(N-chloromethyl nervosine VII), were isolated from Liparis nervosa. Their structures were elucidated by extensive spectroscopic analyses. Most of these compounds were investigated for their cytotoxicity in vitro against HCT116 human cancer cell line, and the results showed that chloride-(N-chloromethyl nervosine VII) induced tumor cell death in a dose-dependent manner. Furthermore, the mechanisms underlying its cytotoxicity were investigated, including apoptosis and autophagy. Apoptosis in HCT116 cells was associated with up-regulation of caspase-3 and -9 expressions by activation of the mitochondrial pathway. The autophagy inducing effect was associated with the regulation of autophagic markers, including LC3-II, p62, and Beclin 1. Mechanistic studies showed that JNK, ERK1/2, and p38 MAPKs signaling cascades play an important role in chloride-(N-chloromethyl nervosine VII) induced autophagy and apoptosis.

A new nervogenic acid glycoside with pro-coagulant activity from Liparis nervosa.[Pubmed: 24079181]
In an effort to identify hemostatic components from Liparis nervosa (Thunb.) Lindl. using a bioactivity-guided fractionation approach, the n-BuOH extract was found to promote ADP-induced platelet aggregation and two compounds were isolated from the active extract. Compound 1 was a new nervogenic acid glycoside and the structure was elucidated as 3,5-bis(3-methyl-but-2-enyl)-4-O-[beta-D-xylopyranosyl-(1 -->2)-beta-D-glucopyranosyl]-benzoic acid by extensive spectroscopic measurements. Adenosine (2) was isolated from this plant for the first time. Compound 1 also showed good pro-coagulant activity in vitro.
Pyrrolizidine alkaloids from Liparis nervosa with inhibitory activities against LPS-induced NO production in RAW264.7 macrophages.[Pubmed: 23571028]
Six pyrrolizidine alkaloids were isolated from the whole herb of Liparis nervosa together with two previously known ones. Their structures were elucidated by extensive spectroscopic analyses and chemical reactions. The cytotoxicity of the isolates was evaluated against A549, HepG2, and MCF-7 human cancer cell lines; however, no significant growth inhibition was observed. All compounds were evaluated for the inhibition of LPS-induced nitric oxide (NO) production in RAW264.7 macrophages, and most significantly inhibited NO production with IC50 values in the range of 2.16-38.25 μM.
New nervogenic acid derivatives from Liparis nervosa.[Pubmed: 23322560]
Ten new nervogenic acid derivatives (1-4, 6-11) and one known compound (5) have been isolated from Liparis nervosa. Their structures were determined using extensive spectroscopic analysis, including 1D and 2D NMR experiments. Compounds 3, 4, 9, 10, and 11 were evaluated for their cytotoxicity against A549, H460, Hela, MCF-7, Caco2, and HepG2 human cancer cell lines.
