To study sesquiterpenes from the root of Chloranthus serratus.

Shizukaol D, a Dimeric Sesquiterpene Isolated from Chloranthus serratus, Represses the Growth of Human Liver Cancer Cells by Modulating Wnt Signalling Pathway.[Pubmed: 27010735]

Natural products have become sources of developing new drugs for the treatment of cancer. To seek candidate compounds that inhibit the growth of liver cancer, components of Chloranthus serratus were tested. Here, we report that shizukaol D, a dimeric sesquiterpene from Chloranthus serratus, exerted a growth inhibition effect on liver cancer cells in a dose- and time-dependent manner. We demonstrated that shizukaol D induced cells to undergo apoptosis. More importantly, shizukaol D attenuated Wnt signalling and reduced the expression of endogenous Wnt target genes, which resulted in decreased expression of β-catenin. Collectively, this study demonstrated that shizukaol D inhibited the growth of liver cancer cells by modulating Wnt pathway.

Labdane diterpenes from Chloranthus serratus.[Pubmed: 23994232]

Five new labdane diterpenes (1-5), serralabdanes A-E, were isolated from the whole plant of Chloranthus serratus. Their structures were elucidated by spectroscopic methods, and the absolute configuration of the 12,13-diol moiety in serralabdane C (3) was determined by observing the induced circular dichroism (ICD) after addition of dimolybdenum teracetate in DMSO solution. Serralabdanes A-E (1-5) showed inhibitory effects on lipopolysaccharide-induced nitric oxide production in RAW264.7 cells.

Serratustones A and B representing a new dimerization pattern of two types of sesquiterpenoids from Chloranthus serratus.[Pubmed: 22651226]

Serratustones A (1) and B (2), featuring a new carbon skeleton and representing a novel dimerization pattern of two different types of sesquiterpenoids, were isolated from Chloranthus serratus. Their structures with absolute configuration were determined on the basis of a detailed explanation of spectroscopic data, X-ray crystallography, and CD analysis in combination with ECD calculation.

Terpenoids from Chloranthus serratus and their anti-inflammatory activities.[Pubmed: 22372956]

Seven new terpenoids, including two sesquiterpene dimers (1, 2), two norditerpenoids (3, 4), and three sesquiterpenes (5-7), along with six known sesquiterpene dimers and four known sesquiterpenes were isolated from the whole plant of Chloranthus serratus. Their structures and relative configurations were elucidated on the basis of spectroscopic data analysis. The absolute configuration of 1 was determined by the CD exciton chirality method. These isolates were evaluated for their inhibitory effects on lipopolysaccharide-induced nitric oxide production in RAW264.7 cells. Compound 2 and two known compounds, shizukaols B and D, showed significant anti-inflammatory activities, with IC(50) values of 0.22, 0.15, and 7.22 μM, respectively.

Sesquiterpenoids and phenylpropanoids from Chloranthus serratus.[Pubmed: 19053511]

Seven new sesquiterpenoids, chlorantenes A-G (1-7), two new phenylpropanoids (8 and 9), and six known sesquiterpenoids were isolated from the whole plants of Chloranthus serratus. Their structures were elucidated on the basis of spectroscopic analyses. Chlorantene A (1) was a sesquiterpene with a unique C-4 and C-10 linkage, and chlorantene B (2) possessed a nitro group at C-1. The structure of a eudesmane-type sesquiterpene previously isolated from Chloranthus henryi was revised as its 4-epimer (3a).
