Chemical Constituents from Euphorbia kansui.

ABSTRACT: In this research, a new triterpenoid, tirucalla-8,24-diene-3?,11?-diol-7-one (1), and eupha-8,24-diene-3?,11?-diol-7-one (2), which was isolated from Euphorbia kansui for the first time, together with twelve other known compounds (3-14), were isolated from the ethyl acetate extract of Euphorbia kansui. Their structures were elucidated based on High resolution electrospray ionization mass spectrometry (HR-ESI-MS), Infrared Spectroscopy (IR), 1D and 2D Nuclear Magnetic Resonance (NMR) data. Both constituents 1 and 2 exhibited moderate cytotoxicity against colon cancer HCT-116, gastric cancer MKN-45 and breast cancer MCF-7.

Chemical constituents from the aerial parts of Euphorbia sikkimensis and their bioactivities

Project description:Phytochemical investigation of the aerial parts of Euphorbia sikkimensis led to the isolation of one new diterpenoids, named sikkimenoid E (1), together with thirteen other known compounds (2–14). Their structures were established by means of spectroscopic methods. Compound 2 was identified to be a trinortriterpenoid, and derived for the first time from a natural source. In this paper we reveal for the first time its comprehensive spectral data and NMR spectral assignment. Compound 4 showed antiangiogenic activity with an IC50 value of 5.66 µM in a zebrafish model, and compounds 5 and 6 exhibited cytotoxicity toward A549 cell line with IC50 values of 12.12 and 6.45 µM, respectively. Electronic Supplementary Material Supplementary material is available for this article at 10.1007/s13659-013-0006-y and is accessible for authorized users.

Inhibition of 11b-HSD1 by tetracyclic triterpenoids from Euphorbia kansui.

Project description:The roots of Euphorbia kansui are considered an important traditional folk medicine. In this study the ethanol extracts of E. kansui were investigated. A new tetracyclic triterpenoid, euphane-3b,20-dihydroxy-24-ene, in addition to five known triterpenoids with euphane skeletons were isolated. Their structures were elucidated on the basis of physical and spectral techniques (1D-, 2D-NMR and MS, respectively). Furthermore, these compounds 1-6 exhibited strong inhibitory activity against human 11b-hydroxysteroid dehydrogenase type 1 (11b-HSD1), with IC(50) values of 34.86 nM, 1.115 mM, 16.08 nM, 2.815 nM, 26.47 nM, 15.99 nM, and 41.86 nM, respectively. The docking results show that the ring part of compounds can insert into the hydrophobic core of h11b-HSD1 and the alkane chain orientates toward the outside. The results presented herein provide a scientific explanation for the usage of the E. kansui in clinical treatment of diabetes.

MicroRNAome Profile of Euphorbia kansui in Response to Methyl Jasmonate.

Project description:miRNAs play vital regulatory roles in different plant developmental stages and in plant response to biotic and abiotic stresses. However, information is limited on the miRNA regulatory mechanism to methyl jasmonate (MeJA). In this study, we used the microRNAome profile to illustrate the relevant regulatory mechanisms of Euphorbia kansui in response to methyl jasmonate (MeJA) through Illumina RNA-Seq. As a result, we identified 875 miRNAs corresponding to 11,277 target mRNAs, among them, 168 known miRNA families representing 6019 target mRNAs sequences were obtained. 452 miRNA-mRNA pairs presented an anti-correlationship (Cor < -0.50 and p-value of correlation ≤ 0.05). The miRNA with a fold change ≥ 2 and a p (p-Value) < 0.05 in pairwise comparison were identified as significant differentially expressed miRNAs (DEMs). The DEMs in MeJA treatment of 0, 24, 36 and 48 h were compared by using Short Time Expression Miner (STEM) cluster and 4 significant gene profiles (p-value ≤ 0.02) were identified. Through the kyoto encyclopedia of genes and genomes (KEGG) pathway and gene ontology (GO) enrichment analysis on all miRNA targets, we identified 33 mRNAs in terpenoid biosynthesis, which were regulated by miRNAs under MeJA treatment, so the miRNA maybe involved in the response of E. kansui plant to exogenous MeJA and the results would provide very useful information on illustrating the regulatory mechanism of E. kansui and also provide an overall view of the miRNAs response to MeJA stress of a non-model plant.

Research Progress on Chemical Constituents and Anticancer Pharmacological Activities of Euphorbia lunulata Bunge.

Project description:Euphorbia lunulata Bunge (ELB) is a traditional Chinese medicine possessing the functions of expectoration, cough relief, asthma relief, detoxification, and itching relief. Modern pharmacological studies have showed that ELB exhibits a variety of activities, such as antitumor, antibacterial, and antioxidant activities. In particular, the anticancer activities of ELB have attracted much attention. In this review, we summarize the recent research progress on the chemical constituents and anticancer activities of ELB by searching the PubMed, Web of Science, and China National Knowledge Infrastructure databases. The results show that more than 151 components have been identified from extracts of ELB, including 73 terpenoids, 28 flavonoids, 8 phenylpropanoids, 7 steroids, 19 phenols, and 5 alkaloids. ELB has been shown to exhibit significant inhibitory effects on lung, cervical, gastric, breast, and liver cancers, and its anticancer effects are mainly manifested in the 3 aspects, including cell cycle arrest, cell apoptosis, and inhibition of the migration of cancer cells.

Reactivation of HIV-1 from Latency by an Ingenol Derivative from Euphorbia Kansui.

Project description:Cells harboring latent HIV-1 pose a major obstacle to eradication of the virus. The 'shock and kill' strategy has been broadly explored to purge the latent reservoir; however, none of the current latency-reversing agents (LRAs) can safely and effectively activate the latent virus in patients. In this study, we report an ingenol derivative called EK-16A, isolated from the traditional Chinese medicinal herb Euphorbia kansui, which displays great potential in reactivating latent HIV-1. A comparison of the doses used to measure the potency indicated EK-16A to be 200-fold more potent than prostratin in reactivating HIV-1 from latently infected cell lines. EK-16A also outperformed prostratin in ex vivo studies on cells from HIV-1-infected individuals, while maintaining minimal cytotoxicity effects on cell viability and T cell activation. Furthermore, EK-16A exhibited synergy with other LRAs in reactivating latent HIV-1. Mechanistic studies indicated EK-16A to be a PKCγ activator, which promoted both HIV-1 transcription initiation by NF-κB and elongation by P-TEFb signal pathways. Further investigations aimed to add this compound to the therapeutic arsenal for HIV-1 eradication are in the pipeline.

iTRAQ-Based Proteomics Analysis of Autophagy-Mediated Responses against MeJA in Laticifers of Euphorbia kansui L.

Project description:Autophagy is a well-defined catabolic mechanism whereby cytoplasmic materials are engulfed into a structure termed the autophagosome. Methyl jasmonate (MeJA), a plant hormone, mediates diverse developmental process and defense responses which induce a variety of metabolites. In plants, little is known about autophagy-mediated responses against MeJA. In this study, we used high-throughput comparative proteomics to identify proteins of latex in the laticifers. The isobaric tags for relative and absolute quantification (iTRAQ) MS/MS proteomics were performed, and 298 proteins among MeJA treated groups and the control group of Euphorbia kansui were identified. It is interesting to note that 29 significant differentially expressed proteins were identified and their associations with autophagy and ROS pathway were verified for several selected proteins as follows: α-L-fucosidase, β-galactosidase, cysteine proteinase, and Cu/Zn superoxide dismutase. Quantitative real-time PCR analysis of the selected genes confirmed the fact that MeJA might enhance the expression of some genes related to autophagy. The western blotting and immunofluorescence results of ATG8 and ATG18a which are two important proteins for the formation of autophagosomes also demonstrated that MeJA could promote autophagy at the protein level. Using the electron microscope, we observed an increase in autophagosomes after MeJA treatment. These results indicated that MeJA might promote autophagy in E. kansui laticifers; and it was speculated that MeJA mediated autophagy through two possible ways: the increase of ROS induces ATG8 accumulation and then aotophagosome formation, and MeJA promotes ATG18 accumulation and then autophagosome formation. Taken together, our results provide several novel insights for understanding the mechanism between autophagy and MeJA treatment. However, the specific mechanism remains to be further studied in the future.
