Abstract

Malignant ascites (MA) is one of the severe complications of gastrointestinal tumors, affecting the patients’ survival time and quality of life. Euphorbia kansui is a commonly used toxic Chinese herbal medicine for malignant ascites. Our previous study showed that the biological and toxicological effects of kansui were closely related to the gastrointestinal tract. The ingenane-type and jastrophane-type diterpenoids are both toxic and active components of kansui. The contents of kansuiphorin C (KPC) and kansuinin A (KA) take highest accounts in each type of diterpene. Hence, in this study, the efficacy and toxicity of KPC and KA on normal rats and MA rats were firstly evaluated by serum liver enzymes (ALT and AST), oxidative damage indicators (GSH, SOD, MDA and LDH), inflammatory indexes (TNF-α, IFN-γ and IL-2) and the volume of ascites. Changes in the levels of these indices showed that although the toxicity of KPC on normal rats was stronger than KA, KPC exhibited better efficacy to the malignant ascites with no obvious side effects at the dose of 10 mg·kg-1. Then, accurate and reliable methods for the determination of KPC and KA in the rat feces by ultra-fast liquid chromatography coupled with MS/MS detector (UFLC-MS/MS) were established, detected by the multiple reaction monitoring mode. The chromatographic separation was conducted on an XBbridge C18 column (50 mm × 2.1 mm, 2.5 μm) using gradient elution composed of 0.1% formic acid in water and acetonitrile. The flow rate was 0.5 mL·min-1 and column temperature was 30 °C. The method was finally applied to the comparative study on normal and malignant ascites rats given KPC and KA, respectively. Interestingly, the results showed that KPC’s accumulative fecal excretion rate (normal, 19.22%±5.36%; model, 15.96%±3.47%) were much higher than that of KA (normal, 2.928%±0.741%; model, 2.835%±0.873%) at the same dose within 48 h. This suggested KPC had higher in-vivo transformations in comparison with KA, providing guidance for the further preclinical research of KPC and KA as promising compounds treating MA.

Abstract

BACKGROUND:
Kansui Radix (Gansui in Chinese), the dried tuber of Euphorbia kansui, is a Chinese medicinal herb commonly used for the treatment of oedema and ascites with dyspnea. Because of its toxic nature, the herb is usually processed with vinegar to reduce the toxicity. A report has shown that the contents of toxic terpenoids in Gansui decreased after processing with vinegar. However, comprehensive comparison of the chemical profiles between vinegar-processed and raw Gansui has not yet been conducted.

METHODS:
An ultra-high-performance liquid chromatography in conjunction with ultra-high resolution quadrupole time-of-flight mass spectrometry (UHPLC UHD Q-TOF MS/MS) method was developed for the analysis of chemical profiles of vinegar-processed and raw Gansui in this study.

RESULTS:
Results showed that processing with vinegar caused conspicuous chemical changes. Among the altered components, 11 toxic terpenoids, 3-O-benzoyl-13-O- dodecanoylingenol/20-O-benzoyl-13-O-dodecanoylingenol, kansuinine D, kansuinine A, 3-O-benzoyl-13-O-dodecanoylingenol/20-O-benzoyl-13-O-dodecanoylingenol, 3-O- benzoylingenol/20-O-benzoylingenol, 20-O-(2’E,4’Z-decadienoyl)ingenol/20-O-(2’E,4’E- decadienoyl)ingenol/3-O-(2’E,4’Z-decadienoyl)ingenol/3-O-(2’E,4’E-decadienoyl)ingenol, 3-O-(2’E,4’Z-decadienoyl)-20-deoxyingenol,3-O-(2’E,4’Z-,ecadienoyl)-5-O-acetylingenol,3-O-(2’E,4’Z-decadienoyl)-20-O-acetylingenol,3-O-(2,3-dimethylbutanoyl)-13-O-dodecanoylingenol, were tentatively identified. The contents of most of these terpenoids were obviously decreased after processing with reductions of 6.66-95.25%.

CONCLUSION:
Our findings could help us understand the chemical basis for the toxicity reduction of Gansui afforded by processing with vinegar. Further investigations are warranted to establish the relationship between processing-induced chemical changes and the reduction of toxicity of Gansui.

Abstract

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.
