Kansuinine A and Kansuinine B from Euphorbia kansui L. inhibit IL-6-induced Stat3 activation
Planta Med 2010 Oct;76(14):1544-9.PMID:20379953DOI:10.1055/s-0030-1249805.
The current study was performed to examine the mechanisms underlying the potential effects of E. KANSUI on IL-6-induced cellular signaling in human hepatoma cells. We found that two diterpenoids, kansuinine A and B, from E. KANSUI have an inhibitory effect on IL-6-induced Stat3 activation by activating ERK1/2. Inhibition of MEK significantly blocked the effects of kansuinine A and B on IL-6-induced Stat3 activation and tyrosine phosphorylation. These results suggest that blocking of IL-6-induced signal transduction is partially due to the sustained activation of ERK1/2 by kansuinine A and B, which in turn results in an increase of Stat3 serine phosphorylation and SOCS-3 expression. Treatment with kansuinine A and B represents a novel method to block these IL-6-induced effects.
Bioassay-guided separation of the proinflammatory constituents from the roots of Euphorbia kansui
J Nat Med 2010 Jan;64(1):98-103.PMID:19844773DOI:10.1007/s11418-009-0366-0.
In view of the toxic inflammatory reaction induced by Euphorbia kansui roots, a traditional Chinese medicine used for the treatment of edema, ascites, and asthma, the 95% ethanol extract was found to have a significant stimulating effect on inflammatory cells. Bioassay-guided separation of the 95% ethanol extract from the roots of E. kansui led to the isolation of five diterpenoids whose structures were identified by (1)H, (13)C NMR spectroscopy and HR-ESI-MS as Kansuinine B (1), kansuinine A (2), kansuiphorin C (3), 3-O-benzoyl-20-deoxyingenol (4), and 3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol (5). The proinflammatory effect of compounds 1-5 was evaluated in vitro in models of inflammation using exoteric mice splenic lymphocytes (SPL) and rat peritoneal macrophages (PMphi). Compounds 1, 2, and 5 markedly promoted SPL proliferation and NO production by PMphi at concentrations from 0.78 to 12.50 microg/mL. Hence the three compounds are believed to be important proinflammatory components of the roots of E. kansui.
Bio-guided isolation of the cytotoxic terpenoids from the roots of Euphorbia kansui against human normal cell lines L-O2 and GES-1
Int J Mol Sci 2012;13(9):11247-11259.PMID:23109850DOI:10.3390/ijms130911247.
The dried roots of Euphorbia kansui (kansui) have been used for centuries in China as a herbal medicine for edema, ascites, and asthma. The 95% ethanol extract showed a significant inhibition of cell proliferation against human normal cell lines L-O2 and GES-1. Bioassay-guided separation of the 95% ethanol extract from the roots of E. kansui led to the isolation of 12 diverse terpenoids whose structures were identified by (1)H, (13)C NMR spectroscopy and ESI-MS as kansuinine A (1), Kansuinine B (2), kansuinine C (3), kansuiphorin C (4), 3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol (5), 3-O-(2'E,4'Edecadienoyl)-20-O-acetylingenol (6), 3-O-(2'E,4'Z-decadienoyl)-20-deoxyingenol (7), 3-O-benzoyl-20-deoxyingenol (8), 5-O-benzoyl-20-deoxyingenol (9), kansenone (10), epi-kansenone (11), euphol (12). All these 12 terpernoids were evaluated in vitro for cytotoxicity on L-O2 and GES-1 cell lines. Most ingenane-type diterpenoids and 8-ene-7-one triterpenoids (5-11) exhibited a relatively lower IC(50) value; therefore, these compounds had stronger cytotoxicity against human normal cell lines L-O2 and GES-1 with dose-dependent relationships. These results will be significantly helpful to reveal the mechanism of toxicity of kansui and to effectively guide safer clinical application of this herb.
