[LC/MS/MS Analysis of the Metabolites of Lathyrane Diterpenoids in Caco-2 Cells]
Zhong Yao Cai 2016 Aug;39(8):1771-4.PMID:30204381doi
Objective: To identify the metabolites of Euphorbetin L1,Euphorbetin L2,Euphorbetin L8 and 6( 17),12( E)-lathyrol-5,15-diacetate-3-phenylacetate in Caco-2 cells by LC/MS/MS. Methods: Caco-2 cells were cultured with 100 μg/mol lathyrane diterpenoid for 3,6,12 h,respectively. Then the samples were collected,purified and identified by LC/MS/MS. Results: The major metabolites of Euphorbetin L1 were two methylated products which were obtained after hydrolysis of the ester. The major metabolites of Euphorbetin L2,Euphorbetin L8 and 6( 17),12( E)-lathyrol-5,15-diacetate-3-phenylacetate were hydrolysis products of the ester. Conclusion: The main metabolic pathway of Euphorbetin L1 is methylation and hydrolysis of the ester. The main metabolic pathway of Euphorbetin L2,Euphorbetin L8 and 6( 17),12( E)-lathyrol-5,15-diacetate-3-phenylacetate is hydrolysis of the ester. LC/MS/MS can identify the metabolites of Euphorbetin L1,Euphorbetin L2,Euphorbetin L8 and 6( 17),12( E)-lathyrol-5,15-diacetate-3-phenylacetate in Caco-2 cells quickly and sensitively.
Phytophenol Dimerization Reaction: From Basic Rules to Diastereoselectivity and Beyond
Molecules 2022 Jul 28;27(15):4842.PMID:35956790DOI:10.3390/molecules27154842.
Phytophenol dimerization, which is a radical-mediated coupling reaction, plays a critical role in many fields, including lignin biosynthesis. To understand the reaction, 2,2-diphenyl-1-picrylhydrazyl radical was used to initiate a series of phytophenol dimerization reactions in methanol. The products were identified using ultra-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (UHPLC-ESI-Q-TOF-MS/MS) analysis in situ. The identified products mainly included biphenols, magnolol, honokiol, gingerol 6,6'-dimers, 3,6-dimethoxylcatechol β,β' dimer, Euphorbetin, bis-eugenol, dehydrodiisoeugenol, trans-ε-viniferin, (+) pinoresinol, and (-) pinoresinol. Structure-function relationship analysis allowed four basic rules to be defined: meta-excluded, C-C bonding domination, ortho-diOH co-activation, and exocyclic C=C involvement. The exocyclic C=C involvement, however, required conjugation with the phenolic core and the para-site of the -OH group, to yield a furan-fused dimer with two chiral centers. Computational chemistry indicated that the entire process was completed via a radical coupling reaction and an intramolecular conjugate addition reaction. Similar results were also found for the horseradish peroxidase (HRP)-catalyzed coniferyl alcohol dimerization, which produced (+) and (-) pinoresinols (but no (-) epipinoresinol), suggesting that the HRP-catalyzed process was essentially an exocyclic C=C-involved phytophenol dimerization reaction. The reaction was highly diastereoselective. This was attributed to the intramolecular reaction, which prohibited Re-attack. The four basic rules and diastereoselectivity can explain and even predict the main products in various chemical and biological events, especially oxidase-catalyzed lignin cyclization.
Antitumor Effect of the Ethanolic Extract from Seeds of Euphorbia lathyris in Colorectal Cancer
Nutrients 2021 Feb 9;13(2):566.PMID:33572111DOI:10.3390/nu13020566.
The seeds of Euphorbia lathyris have been used in traditional medicine to treat various medical conditions. However, neither all of their active biocompounds nor the molecular mechanisms underlying their therapeutic effects have been described. A new ethanolic extract of defatted flour from mature seeds of Euphorbia lathyris showed a high total polyphenol content and significant antioxidant activity. Chromatographic analysis showed that esculetin, Euphorbetin, gaultherin, and kaempferol-3-rutinoside were the most abundant polyphenolic bioactive compounds. Antiproliferative assays showed a high and selective antitumor activity against colon cancer cell lines (T84 and HCT-15). In addition, a significant antiproliferative activity against glioblastoma multiforme cells was also demonstrated. Its mechanism of action to induce cell death was mediated by the overexpression of caspases 9, 3, and 8, and by activation of autophagy. Interestingly, a reduction in the migration capacity of colon cancer cells and a significant antiangiogenic effect on human umbilical vein endothelial cells were also demonstrated. Finally, the extract significantly reduced the subpopulations of cancer stem cells. This extract could be the basis to develop new therapeutic strategies for the treatment of colon cancer, although further experiments will be necessary to determine its in vivo effects.
Colon cancer therapy with calcium phosphate nanoparticles loading bioactive compounds from Euphorbia lathyris: In vitro and in vivo assay
Biomed Pharmacother 2022 Nov;155:113723.PMID:36156367DOI:10.1016/j.biopha.2022.113723.
Amorphous calcium phosphate nanoparticles (ACP NPs) exhibit excellent biocompatibility and biodegradability properties. ACP NPs were functionalized with two coumarin compounds (esculetin and Euphorbetin) extracted from Euphorbia lathyris seeds (BC-ACP NPs) showing high loading capacity (0.03% and 0.34% (w/w) for esculetin and Euphorbetin, respectively) and adsorption efficiency (2.6% and 33.5%, respectively). BC-ACP NPs, no toxic to human blood cells, showed a more selective cytotoxicity against colorectal cancer (CRC) cells (T-84 cells) (IC50, 71.42 µg/ml) compared to non-tumor (CCD18) cells (IC50, 420.77 µg/ml). Both, the inhibition of carbonic anhydrase and autophagic cell death appeared to be involved in their action mechanism. Interestingly, in vivo treatment with BC-ACPs NPs using two different models of CRC induction showed a significant reduction in tumor volume (62%) and a significant decrease in the number and size of polyps. A poor development of tumor vasculature and invasion of normal tissue were also observed. Moreover, treatment increased the bacterial population of Akkermansia by restoring antioxidant systems in the colonic mucosa of mice. These results show a promising pathway to design innovative and more efficient therapies against CRC based on biomimetic calcium phosphate NPs loaded with natural products.
Chemical Constituents from Fraxinus hupehensis and Their Antifungal and Herbicidal Activities
Biomolecules 2020 Jan 2;10(1):74.PMID:31906487DOI:10.3390/biom10010074.
The phytochemical investigation of Fraxinus hupehensis led to the isolation and characterization of ten compounds which were identified as fraxin (1), fraxetin (2), esculetin (3), cichoriin (4), Euphorbetin (5), kaempferol-3-O-β-rutinoside (6), oleuropein (7), linoleic acid (8), methyl linoleate (9), and β-sitosterol (10). Structures of the isolated constituents were characterized by 1H NMR, 13C NMR and HRMS. All the compounds, except compounds 3 and 4, were isolated for the first time from this plant. Further, this was the first report for the occurrence of compound 5 in the Fraxinus species. Antifungal activity evaluation showed that compound 2 exhibited significant inhibitory effects against Bipolaris maydis, Sclerotium rolfsii, and Alternaria solani with EC50 values of 0.31 ± 0.01 mmol/L, 10.50 ± 0.02 mmol/L, and 0.40 ± 0.02 mmol/L respectively, compared to the positive control, Carbendazim, with its EC50 values of 0.74 ± 0.01 mmol/L, 1.78 ± 0.01 mmol/L and 1.41 ± 0.00 mmol/L. Herbicidal activity tests showed that compounds 8-10 had strong inhibitory effects against the roots of Echinochloa crus-galli with EC50 values of 1.16 ± 0.23 mmol/L, 1.28 ± 0.58 mmol/L and 1.33 ± 0.35 mmol/L respectively, more potently active than that of the positive control, Cyanazine, with its EC50 values of 1.56 ± 0.44 mmol/L. However, none of the compounds proved to be active against the tested bacteria (Erwinia carotovora, Pseudomonas syringae, and Ralstonia solanacearum).
