Nat Prod Res 2024:1-17. [PMID: 39205630 DOI: 10.1080/14786419.2024.2397554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 07/23/2024] [Accepted: 08/22/2024] [Indexed: 09/04/2024]
Abstract
Euphorbia pekinensis Rupr. is a traditional herb generally distributed in most areas of China, north Korea and Japan. The dried roots of Euphorbia pekinensis Rupr. (REP), famous as 'Jing Da Ji' () have been applied as traditional herb medicines to expel water and rheum; disperse swelling, dissipate binds and to treat edoema, pleural effusions, uraemia, nephritis, cirrhosis with ascites, as well as other diseases. Recent advances in botany, traditional uses, phytochemistry, pharmacology, quality control, and toxicology of E. pekinensis roots are methodically outlined and current limitations as well as future perspectives also are discussed in order to guide scientifical investigation and rational application of REP. Up to now, 79 structurally diverse compounds have been obtained and characterised from REP, principally including diterpenoids, triterpenoids, tannins, phenols, and 29 volatile constituents. Among which, diterpenoids are considered as primary characteristic and active constituents. The extracts and individual compounds from REP have demonstrated significant pharmacological effects such as diuretic and purgative, anti-inflammatory, and cytotoxic effects. REP are widely used in traditional medicine due to diverse chemical constituents with obvious pharmacological effects. Modern phytochemical and pharmacological studies justified and explained relevant traditional uses of REP and offer worthy clues for new medical fields of industrial application. Nevertheless, a great number of thorough and detailed investigations should be carried out in active constituents, mechanisms of action, quality-marker, toxicology assessment, and detoxification mechanisms of REP.

[PMID: 38790983 PMCID: PMC11117879 DOI: 10.3390/biomedicines12051021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 04/29/2024] [Accepted: 05/01/2024] [Indexed: 05/26/2024] Open
Abstract
The main focus of this review is to introduce readers to the fascinating class of lipid molecules known as norsteroids, exploring their distribution across various biotopes and their biological activities. The review provides an in-depth analysis of various modified steroids, including A, B, C, and D-norsteroids, each characterized by distinct structural alterations. These modifications, which range from the removal of specific methyl groups to changes in the steroid core, result in unique molecular architectures that significantly impact their biological activity and therapeutic potential. The discussion on A, B, C, and D-norsteroids sheds light on their unique configurations and how these structural modifications influence their pharmacological properties. The review also presents examples from natural sources that produce a diverse array of steroids with distinct structures, including the aforementioned A, B, C, and D-nor variants. These compounds are sourced from marine organisms like sponges, soft corals, and starfish, as well as terrestrial entities such as plants, fungi, and bacteria. The exploration of these steroids encompasses their biosynthesis, ecological significance, and potential medical applications, highlighting a crucial area of interest in pharmacology and natural product chemistry. The review emphasizes the importance of researching these steroids for drug development, particularly in addressing diseases where conventional medications are inadequate or for conditions lacking sufficient therapeutic options. Examples of norsteroid synthesis are provided to illustrate the practical applications of this research.

Abstract
The roots of the plant Euphorbia ebracteolata Hayata (Yue Xian Da Ji) are commonly used in traditional Chinese medicine to treat multiple diseases such as chronic liver diseases, oedema, pulmonary diseases and cancer. It is the main ingredient of the TCM called Langdu which can be prepared also from roots of E. fischeriana Steud. and occasionally from Stellera chamaejasme species. Numerous bioactive natural products have been isolated from E. ebracteolata including a large diversity of diterpenoids with anti-inflammatory and anticancer properties. One little series of compounds has been named yuexiandajisu (A, B, C, D, D1, E, F) which comprises two casbane-, one isopimarane-, two abietane-, and two rosane-type diterpenes including a dimeric molecule. The origin, structural diversity and properties of these little-known natural products is discussed here. Several of these compounds have been identified in the roots of other Euphorbia species, notably the potent phytotoxic agent yuexiandajisu C. The abietane diterpenes yuexiandajisu D-E exhibit marked anticancer properties but their mechanism of action remains unresolved. The dimeric compound, renamed yuexiandajisu D1, also exhibit anti-proliferative properties against cancer cell lines, unlike the rosane diterpene yuexiandajisu F. The structural or functional analogy with other diterpenoids is discussed.

Abstract
Diterpenes are a class of critical taxonomic markers of the Euphorbiaceae family, representing small compounds (eg, molecules) with a wide range of biological activities and multi-target therapeutic potential. Diterpenes can exert different activities, including antitumor and multi-drug resistance-reversing activities, and antiviral, immunomodulatory, and anti-inflammatory effects, mainly due to their great structural diversity. In particular, one polycyclic skeleton has been highlighted: ingenane. Besides this natural diterpene, promising polycyclic skeletons may be submitted to chemical modification—by in silico approaches, chemical reactions, or biotransformation—putatively providing more active analogs (eg, ingenol derivatives), which are currently under pre-clinical investigation. This review outlines the current mechanisms of action and potential therapeutic implications of ingenol diterpenes as small cancer molecules.

Natural and synthetic plant compounds as anti-biofilm agents against Escherichia coli O157:H7 biofilm. INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2021; 95:105055.

Abstract
Escherichia coli is a common gram-negative bacterium found in the gut and intestinal tract of warm-blooded animals including humans. An evolved seropathotype E. coli O157:H7 (STEC) came into existence in 1982, since then it has been evolved as a stronger and more robust drug-resistant pathotype of E. coli. This drug resistance is due to horizontal gene transfer, natural gene evolution for survival, and most of the cases due to the ability of STEC to switch to the biofilm growth mode from planktonic lifestyle. During the growth in biofilm mode, Escherichia coli O157:H7 opts more robust ability to grow in adverse environments i.e., in presence of antibiotics and other antimicrobial chemicals. Due to the biofilm matrix, the microbial community acquires drug resistance. This makes the treatment of diseases caused by E. coli O157:H7 a complex challenge. To address the illnesses caused by this biofilm-forming pathogen, there are several possible strategies such as antibiotic therapies, synthetic antimicrobial chemicals, adjunct therapy of synergistic effect of multiple drugs, and more importantly plant originated compounds as a new anti-biofilm candidate. The present review summarizes various phytochemicals and their derivatives reported in the last decade mostly to eliminate the biofilm of STEC. The review will progressively reveal the antibiofilm mechanism of the phytochemicals against STEC and to be a potential candidate for the development of the future antibacterial drugs to STEC induced infections.

Abstract
Euphorbiaceae is one of the largest families of higher plants, including 7500 species, and many of them are used as medicines in China. From 2013 to 2019, a total of 455 previously undescribed diterpenoids were isolated from 53 species of Euphorbia, and some skeleton types were first discovered from the genus Euphorbia. Most of the diterpenoids isolated from Euphorbia spp. have been tested for their biological activity, and some of them were first reported for Euphorbia diterpenoids in recent years, such as neuroprotection, antimalarial activity and inhibition of osteoclast formation. In this review, we summarize all the isolated diterpenoids from the genus Euphorbia according to their skeleton types, classify all these diterpenoids into 26 normal classes and 37 novel skeleton types, and summarize their biological activity.

Abstract
Of the more than 100 casbane diterpenes known to date, only the eponymous parent hydrocarbon casbene itself has ever been targeted by chemical synthesis. Outlined herein is a conceptually new approach that brings not a single but a variety of casbane derivatives into reach, especially the more highly oxygenated and arguably more relevant members of this family. The key design elements are a catalyst-controlled intramolecular cyclopropanation with or without subsequent equilibration, chain extension of the resulting stereoisomeric cyclopropane building blocks by chemoselective hydroboration/cross-coupling, and the efficient closure of the strained macrobicyclic framework by ring-closing alkyne metathesis. A hydroxy-directed catalytic trans-hydrostannation allows for late-stage diversity. These virtues are manifested in the concise total syntheses of depressin, yuexiandajisu A, and ent-pekinenin C. The last compound turned out to be identical to euphorhylonal A, the structure of which had clearly been misassigned.

Abstract
The first seco-casbane, EBC-329, isolated from the Australian rainforest, was synthesised from (+)-2-carene in seven steps. This endeavour not only established the absolute stereochemical assignment as (8R,9S)-EBC-329, but also identified, via photoisomerisation, a new seco-casbane family member.

Abstract
Hepatocellular carcinoma (HCC) is a malignant primary liver cancer with poor prognosis. In the present study, we report that pekinenin E (PE), a casbane diterpenoid derived from the roots of Euphorbia pekinensis, has a strong antitumor activity against human HCC cells both in vitro and in vivo. PE suppressed the growth of human HCC cells Hep G2 and SMMC-7721. In addition, PE-mediated endoplasmic reticulum (ER) stress caused increasing expressions of C/EBP homologous protein (CHOP), leading to apoptosis in HCC cells both in vitro and in vivo. Inhibition of ER stress with CHOP small interfering RNA or 4-phenyl-butyric acid partially reversed PE-induced cell death. Furthermore, PE induced S cell cycle arrest, which could also be partially reversed by CHOP knockdown. In all, these findings suggest that PE causes ER stress-associated cell death and cell cycle arrest, and it may serve as a potent agent for curing human HCC.

Laxative Effects of Total Diterpenoids Extracted from the Roots of Euphorbia pekinensis Are Attributable to Alterations of Aquaporins in the Colon. Molecules 2017; 22:molecules22030465. [PMID: 28335427 PMCID: PMC6155307 DOI: 10.3390/molecules22030465] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2017] [Revised: 03/08/2017] [Accepted: 03/12/2017] [Indexed: 12/21/2022] Open
Abstract
This study was designed to evaluate the toxic effects of total diterpenoids extracted from the roots of Euphorbia pekinensis (TDEP) on the mouse colon and to clarify the mechanism. Dried powdered roots of E. pekinensis were extracted with chloroform, and then the extract (6.7 g) was subjected to column chromatography and preparative TLC, giving TDEP. Using the HPLC-DAD method, the purity of TDEP was determined as 85.26%. Mice were orally administered with TDEP (3.942, 19.71 and 39.42 mg/kg), after which fecal water content and colon water content were examined. Both of them increased over time after TDEP administration, accompanied by severe diarrhea. Three hours after TDEP administration, the animals were sacrificed to obtain their colons. The mRNA and protein expression levels of aquaporin 1 (AQP1), AQP3 and AQP4 in the colon were measured using real-time RT-PCR and Western blotting, respectively. TDEP significantly increased the levels of AQP3 and AQP4, but decreased that of AQP1 in dose-dependent manners. Similarly, Pekinenin C, a casbane diterpenoid, significantly increased AQP3 protein and mRNA expressions in human intestinal epithelial cells (HT-29). Histopathological examination revealed that the colon was not significantly damaged. The laxative effects of E. pekinensis were associated with the alterations of AQPs in the colon by TDEP.

Abstract
Pekinenin C is a casbane diterpenoid separated from the root of the traditional Chinese medicine, Euphorbia pekinensis Rupr., which is used as drug for the treatment of edema, ascites, and hydrothorax. Whereas pekinenin C exhibits severe cytotoxicity, the exact toxicity mechanism is unclear. In this study, the effects of pekinenin C on cell inhibition, cell cycle, and cell apoptosis were examined to explain its toxic mechanism. The proliferation of IEC-6 cells was accessed via MTT colorimetric assay after incubated with different concentrations of pekinenin C. Pekinenin C-treated IEC-6 cells labeled with RNase/PI and Annexin V/PI were analyzed by flow cytometric analyses for evaluation of cell cycle distribution and cell apoptosis, respectively. The apoptosis mechanism of pekinenin C on IEC-6 was investigated through assaying the activities of caspase-3, 8, 9 by enzyme-linked immunosorbent assay (ELISA), protein expression of Bax, Bcl-2, apoptosis-inducing factor (AIF), Apaf-1, Fas-associated death domain (FADD) and type 1-associated death domain (TRADD) by Western-blot, mRNA expression of Fas receptor (FasR), Fas ligand (FasL), tumor necrosis factor receptor (TNFR1) and NF-κB by RT-PCR. The results showed that pekinenin C has exhibited obvious IEC-6 cells toxicity and the IC50 value was 2.1 μg·mL(-1). Typical apoptosis characteristics were observed under a transmission electron microscopy, and it was found that pekinenin C could cause G0/G1 phase arrest in IEC-6 cells in a dose-dependent manner and induce apoptosis of IEC-6 cells. Additionally, pekinenin C could increase the expressions of Bax, AIF, Apaf-1, FasR, FasL, TNFR1 and NF-κB, suppress the expression of Bcl-2, FADD and TRADD, then activate caspase-3, 8, 9 cascades, and at last result in apoptosis. These results demonstrated that pekinenin C effectively promoted cell apoptosis, and induced IEC-6 cells apoptosis through both the mitochondrial and death receptor pathways.

Abstract
Ten diterpenoids, named macrorilone A-B, macroripremyrsinone A, macrorilathyrone A-B, macrorieuphorone A-B and macroricasbalone A-C, together with ten known diterpenoids, jatrophalone, sikkimenoids A-D, jatrophodione A, latilagascenes F, jolkinol B, 15β-O-benzoyl-5α-hydroxyisolathyrol and jatrophalactone were isolated from the whole plant of Euphorbia macrorrhiza C.A. Mey. These diterpenoids belong to six skeleton-types, including jatropholane, premyrsinane, lathyrane, euphoractin, casbene and rhamnofolane diterpenoids. Their structures were elucidated by extensive analysis of 1D, 2D NMR and HRESIMS spectroscopic data. The absolute configurations of macrorilone B, macroripremyrsinone A and macrorilathyrone A were established by comparing their experimental and calculated electronic circular dichroism (ECD) spectra. Several of the isolated compounds exhibited weak cytotoxicity against the KB and KBv200 cell lines with IC50 values ranging from 21.19 to 47.87μM. Some also showed multidrug resistance (MDR) reversal activity, among which macrorilathyrone B exhibited a remarkable inhibitory effect on P-gp-mediated drug exclusion.

Abstract
(-)-(1S)-15-Hydroxy-18-carboxycembrene, the first cembrane-type diterpenoid found in the family Euphorbiaceae, isolated from Euphorbiae pekinensis Radix, was identified to be nephrotoxic using HEK 293T cells. Tests on cell morphology, cell viability and biochemical markers about oxidation stress were carried out using inverted microscope, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and commercial kits respectively, which proved the diterpene time- and dose-dependently decreased cells proliferation. Besides, a sensitive and robust UFLC-MS/MS method was developed and fully validated to investigate the in vivo behavior in rats of the diterpene after oral administration of Euphorbiae pekinensis Radix extracts at a dosage of 9g/kg. The method showed a good linearity in tested range (3-1500ng/mL) with acceptable accuracy and precision. The recovery of the diterpene was more than 85% and the matrix effect was within ±20%. The toxicokinetics parameters indicate the diterpene reached Cmax quickly and slowly eliminate. The study proved the newly found diterpene was one of the nephrotoxic substances of Euphorbiae pekinensis Radix and revealed its toxicokinetics behavior.

Abstract
According to traditional Chinese medicine theories, Euphorbiae Pekinensis Radix and Glycyrrhizae Radix should not be used together in one prescription, because their interaction leads to an unexpected consequence. However, the mechanism remains unclear. The purpose of this study was to find out whether CYP2C9 was involved in this herb–herb interaction by using tolbutamide as a probe substrate in vivo and in vitro. Both Euphorbiae Pekinensis Radix and Glycyrrhizae Radix showed induction activity toward CYP2C9, while the combination of them showed a more potent induction activity toward CYP2C9 in vivo. In vitro study revealed only the combination of the herbs could induce the activity of CYP2C9. Thus, both in vivo and in vitro study indicated combination of Glycyrrhizae Radix and Euphorbiae Pekinensis Radix could induce the activity of CYP2C9 to a high level, which may result in decreased plasma levels of major active ingredients of these two herbs, as well as other herbs in the prescriptions. Further research also appears to be necessary to identify the main enzymes involved in the metabolism of the active ingredients in Glycyrrhizae Radix and Euphorbiae Pekinensis Radix.

NATURAL PRODUCTS AND BIOPROSPECTING 2014; 4:91-100. [PMID: 24859600 PMCID: PMC4004854 DOI: 10.1007/s13659-014-0009-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2014] [Accepted: 03/14/2014] [Indexed: 05/04/2023]
Abstract
The perennial herbaceous plant Euphorbia jolkinii (Euphorbiaceae) is a noxious weed widely distributed in the grasslands of northwestern Yunnan and has greatly threatened the local biodiversity. Phytochemical investigation on the fresh roots of E. jolkinii afforded six new diterpenoids 1, 2, 4-6, and 8, together with fifteen known diterpenoids. Their structures were elucidated on the basis of 1D and 2D NMR and other spectroscopic methods. Casbane, lathyrane, abietane, and ent-kaurane diterpenoids were reported from this plant for the first time. Selected compounds were evaluated for their antifeedant and anti-RSV (respiratory syncytial virus) activities. Compound 2 and ingenol (3) exhibited moderate antifeedant activity against a generalist insect herbivore, Spodoptera exigua, with EC50 values of 17.88 and 17.71 μg/cm(2) respectively. Compound 19 showed significant anti-RSV activity, with 50 % inhibition (IC50) value of 10.0 μM and selective index of 8.0. Compounds 1 and 2 were less active against RSV virus, both with IC50 value of 25 μM, and with selective indices of 1.0 and 3.2 respectively. These findings provided new evidence for the biological functions and utilization of the diversified diterpenoid metabolites in the roots of this rich but harmful plant.
