[PMID: 38663782 DOI: 10.1016/j.jep.2024.118252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 04/17/2024] [Accepted: 04/22/2024] [Indexed: 04/30/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atractylis aristata batt., as an endemic plant from the Asteraceae family, holds a significant position in the Ahaggar region of southern Algeria's traditional medicine. The aerial parts of Atractylis aristata was used to cure inflammation, fever, and stomach disorders. AIM OF THE STUDY The objective of the present investigation was to ascertain the overall bioactive components and phytochemical components and examine the antioxidant, antidiabetic, anti-inflammatory, acute toxicity, and sedative properties of the crude extract obtained from the aerial portions of Atractylis aristata (AaME). MATERIALS AND METHODS The AaME's antioxidant activity was assessed by the use of pyrogallol autoxidation, (1,1 diphenyl-2-picrylhydrazyl) (DPPH), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and reducing power (RP) techniques. 1 mg/mL of AaME was used to evaluate the antidiabetic activity by applying the enzyme α-amylase inhibitory power test. At the same time, the bovine serum albumin (BSA) denaturation method was employed to quantify the in vitro anti-inflammatory activity at different concentrations (1.5625, 0.78125, 0.390625, 0.1953125 and 0.09765625 mg/mL). In contrast, following the Organization for Economic Co-operation and Development (OECD) guideline No. 423, which covers acute oral toxicity testing protocols, the limit dosage test was employed to assess in vivo acute toxicity. At the dose of 0.08 mg/mL, the carrageenan-induced paw edema approach was used to assess the anti-inflammatory efficacy in vivo, and the sedative activity was carried out at the dose of 0.08 mg/mL using the measurement of the locomotor method. Different bioactive compounds were identified within AaME using LC-MS/MS and HPLC-UV analysis. RESULTS The acute toxicity study showed no fatalities or noticeable neurobehavioral consequences at the limit test; this led to their classification in Globally Harmonized System (GHS) category Five, as the OECD guideline No 423 recommended. At a concentration of 0.08 mg/mL (2000 mg/kg), AaME showed apparent inhibition of paw edema and a significant (p = 0.01227) reduction in locomotor activity compared to the control animals. Our findings showed that AaME exhibited considerable antioxidant (IC50 = 0.040 ± 0.003 mg/mL (DPPH), IC50 = 0.005 ± 5.77 × 10-5 mg/mL (ABTS), AEAC = 91.15 ± 3.921 mg (RP) and IR% = 23.81 ± 4.276 (Inhibition rate of pyrogallol) and rebuts antidiabetic activities (I% = 57.6241% ± 2.81772). Our findings revealed that the maximum percentage of BSA inhibition (70.84 ± 0.10%) was obtained at 1.562.5 mg/mL. Thus, the AaME phytochemical profile performed using phytochemical screening, HPLC-UV, and LC-MS/MS analysis demonstrated that A. aristata can be a valuable source of chemicals with biological activity for pharmaceutical manufacturers. CONCLUSION The phytochemical profiling, determined through HPLC-UV and LC-MS/MS applications, reveals this plant's therapeutic value. The aerial parts of Atractylis aristata contain bioactive molecules such as gallic acid, ascorbic acid, and quercetin, contributing to its significant antioxidant capabilities. Furthermore, identifying alizarin, the active compound responsible for its anti-inflammatory properties, could provide evidence supporting the anti-inflammatory capabilities of this subspecies.

Woyda-Ploszczyca AM. Direct and indirect targets of carboxyatractyloside, including overlooked toxicity toward nucleoside diphosphate kinase (NDPK) and mitochondrial H + leak. PHARMACEUTICAL BIOLOGY 2023; 61:372-390. [PMID: 36799406 PMCID: PMC9946330 DOI: 10.1080/13880209.2023.2168704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 12/30/2022] [Accepted: 01/10/2023] [Indexed: 06/18/2023]
Abstract
CONTEXT The toxicity of atractyloside/carboxyatractyloside is generally well recognized and commonly ascribed to the inhibition of mitochondrial ADP/ATP carriers, which are pivotal for oxidative phosphorylation. However, these glycosides may 'paralyze' additional target proteins. OBJECTIVE This review presents many facts about atractyloside/carboxyatractyloside and their plant producers, such as Xanthium spp. (Asteraceae), named cockleburs. METHODS Published studies and other information were obtained from databases, such as 'CABI - Invasive Species Compendium', 'PubMed', and 'The World Checklist of Vascular Plants', from 1957 to December 2022. The following major keywords were used: 'carboxyatractyloside', 'cockleburs', 'hepatotoxicity', 'mitochondria', 'nephrotoxicity', and 'Xanthium'. RESULTS In the third decade of the twenty first century, public awareness of the severe toxicity of cockleburs is still limited. Such toxicity is often only perceived by specialists in Europe and other continents. Interestingly, cocklebur is among the most widely distributed invasive plants worldwide, and the recognition of new European stands of Xanthium spp. is provided here. The findings arising from field and laboratory research conducted by the author revealed that (i) some livestock populations may instinctively avoid eating cocklebur while grazing, (ii) carboxyatractyloside inhibits ADP/GDP metabolism, and (iii) the direct/indirect target proteins of carboxyatractyloside are ambiguous. CONCLUSIONS Many aspects of the Xanthium genus still require substantial investigation/revision in the future, such as the unification of the Latin nomenclature of currently distinguished species, bur morphology status, true fruit (achene) description and biogeography of cockleburs, and a detailed description of the physiological roles of atractyloside/carboxyatractyloside and the toxicity of these glycosides, mainly toward mammals. Therefore, a more careful interpretation of atractyloside/carboxyatractyloside data, including laboratory tests using Xanthium-derived extracts and purified toxins, is needed.

Abstract
Atractyloside, carboxyatractyloside, their aglycon atractyligenin, and several synthetic derivatives were tested and found to be active against a panel of human tumor cell lines. Atractyligenin was subjected to oxidation, bromination, and elimination reactions, obtaining several compounds. A singular skeleton was synthesized by chemical rearrangement starting from 3β-bromo-2,15-diketoatractyligenin methyl ester. The synthesized compounds resulted active against all cell lines tested. In particular, 15-ketoatractyligenin methyl ester and 3β-bromo-2,15-diketoatractyligenin methyl ester resulted the most active with IC50 values of 0.427 and 0.723 μM against A375 melanoma cell line. Excellent results were also obtained against the colon cancer cell line CaCo2, with slightly lower antiproliferative activity. An interesting extension of the study should be to analyze the atractyligenin derivatives also as target for human melanoma and human colon cancer cells.

Abstract
Objective This work aimed to survey medicinal plants used in phytotherapy in the Fez-Boulemane region, Morocco. Methods A comprehensive ethnobotanical survey was conducted using a questionnaire to collect data from thirty herbalists on medicinal plants used for therapeutic purposes in the Fez-Boulemane region, Morocco. Results The mean age of herbalists interviewed was 52.13 years. Forty percent of the herbalists were illiterate, and 73% referred to the experiences of their parents as knowledge of the properties and uses of medicinal plants. One hundred and eight medicinal plants belonging to 51 botanical families were recommended by herbalists in the region of Fez-Boulemane, Morocco, for treatment. According to the respondents, Lawsonia inermis L., Rosmarinus officinalis L., and Lavandula coronopifolia L. were the most used plants with the percentage of 13%, 12%, and 11%, respectively. Most plants had been involved in the treatment of digestive disorders (25%) and osteoarticular diseases (24%). Some (7.4%) of the plants mentioned in our survey were potentially toxic. Conclusion It was learned that irrational use of toxic plants and unknown compositions of recipes are recommended to consumers. As a result, particular attention should be paid to risks related to plants used in traditional treatment without scientific validation. It is envisaged that increasing awareness, by conducting educational campaigns and transferring evidence-based scientific knowledge, on traditional treatments among the local population is expected to have beneficial impacts on health and disease management.

Abstract
Background: Burning incense of Carlina gummifera L. is a traditional practice in North African countries for religious or ritual intentions. Aim: The aim of this study was to investigate the effects of smoke incense of this plant on the reproductive function in adult male rats. Setting and Design: This study was conducted in the Integrated Physiology Laboratory. Materials and Methods: Plant roots were collected, dried and finely ground in powder form. Adult Wistar rats were randomly assigned to treated groups exposed daily during 60 min for 15 consecutive days to smoke incense at 2, 4 and 6 g and a control group was subjected to the same conditions in the absence of smoke. Statistical Analysis Used: Statistical analysis was performed using one-way analysis of variance followed by Tukey's multiple comparison as the post hoc test. Results: Exposure to the incense of Carlina gummifera L. seriously affected dose dependently the reproductive function in male rats. It was found that in treated groups, the testicle relative weight decreased, while those of seminal vesicles and prostate increased when compared to the untreated group. Carlina gummifera L. incense inhalation reduced the total number, viability and mobility of epididymis spermatozoa compared to control. Furthermore, incense exposure induced various histological changes in the testes, prostate and seminal vesicles, including in particular a decrease in the number of gametes in the seminiferous tubes, the reduction of prostatic secretions and the macrophagic resorption of the seminal secretions. The effect of Carlina incense on the antioxidant system was evaluated by assaying the two antioxidant enzyme activities catalase and superoxide dismutase as well as thiol group levels in the testicles. Our results showed that fumigation affected these parameters, suggesting that the morphological and functional modifications in the male reproductive system induced by Carlina gummifera L. incense may be related, in part, to the alteration of the oxidative balance in the testicle. Conclusion: Smoke incense of Carlina gummifera L. caused marked reproductive toxicity in adult male rats associated with induced oxidative stress.

Abstract
The permeability transition (PT) is an increased permeation of the inner mitochondrial membrane due to the opening of the PT pore (PTP), a Ca2+-activated high conductance channel involved in Ca2+ homeostasis and cell death. Alterations of the PTP have been associated with many pathological conditions and its targeting represents an incessant challenge in the field. Although the modulation of the PTP has been extensively explored, the lack of a clear picture of its molecular nature increases the degree of complexity for any target-based approach. Recent advances suggest the existence of at least two mitochondrial permeability pathways mediated by the F-ATP synthase and the ANT, although the exact molecular mechanism leading to channel formation remains elusive for both. A full comprehension of this to-pore conversion will help to assist in drug design and to develop pharmacological treatments for a fine-tuned PT regulation. Here, we will focus on regulatory mechanisms that impinge on the PTP and discuss the relevant literature of PTP targeting compounds with particular attention to F-ATP synthase and ANT.

Abstract
Abstract
Background
Diabetes mellitus is a serious complex multifactorial disorder that imposes huge health and economic burden on societies. Because the currently available medications have many drawbacks, it's important to look for alternative therapies. Medicinal plants utilized in folk medicine are ideal candidates. Therefore, this work assessed the antidiabetic action of n-butanol extract from the whole plant Atractylis flava Desf (BEAF). These ethnomedicinal properties of BEAF were scientifically validated using in vitro and in vivo assays. In vitro antidiabetic effect of the BEAF was conducted using α-Glucosidase and α-Amylase assays. While the antihyperglycemic activity was assessed using two rat models: Alloxan-induced diabetic rats and oral glucose challenged rats. Experimental diabetes was induced by a single intraperitoneal injection of alloxan at a dose of 150 mg/kg and animals with fasting blood glucose levels (BGL) > 200 mg/dL were considered diabetic. Glibenclamide (5 mg/kg) was used as a typical drug.
Results
The BEAF at all tested dose levels (100, 250, and 500 mg/kg) showed a significant decrease in blood glucose level in all the two animal models. Besides, the plant extract exhibited a potent inhibitory effect on α-Amylase and α-Glucosidase activity at a concentration of 1000 µg/mL with 76.17% and 89.37%, respectively.
Conclusion
BEAF exerts in vitro and in vivo antidiabetic effects, these results suggest that the plant extract can be a therapeutic resource in the treatment of diabetes and hyperlipidemia.

Abstract
BACKGROUND Atractylis gummifera L. is a poisonous thistle plant that grows in the Mediterranean regions especially in northern Africa like Morocco and southern Europe. It has been used frequently to treat some diseases in traditional medicine, and its ingestion is a common cause of fatal poisoning. Here, we report 3 death cases in children after accidental ingestion of the Atractylis gummifer L. CASES REPORTS We report 3 cases of death in children after accidental ingestion of the poisonous plant Atractylis gummifer L. The poisoned children were admitted to hospital in deteriorated general state with clinical symptoms, such as nausea, vomiting, epigastric, and abdominal pain, diarrhea, followed by coma. However, they died a few hours later. The postmortem investigations were performed, and the diagnosis of Atractylis gummifer L. poisoning was confirmed by toxicological examination (chromatography), the latter showed the presence of atractyloside (potassium atractylate), a toxic compound of the plant Atractylis gummifera L.Atractylis gummifer L. poisoning was discussed with review through the literature. CONCLUSIONS Through the presented cases, we show that Atractylis gummifera L. poisoning remains a health problem that involves children in Morocco, where the plant grows spontaneously. Thus, teaching children to recognize dangerous plants will be helpful to prevent accidental ingestion.

Abstract
The mitochondrial adenine nucleotide translocator (ANT) plays the fundamental role of gatekeeper of cellular energy flow, carrying out the reversible exchange of ADP for ATP across the inner mitochondrial membrane. ADP enters the mitochondria where, through the oxidative phosphorylation process, it is the substrate of Fo-F1 ATP synthase, producing ATP that is dispatched from the mitochondrion to the cytoplasm of the host cell, where it can be used as energy currency for the metabolic needs of the cell that require energy. Long ago, we performed a method that allowed us to monitor the activity of ANT by continuously detecting the ATP gradually produced inside the mitochondria and exported in the extramitochondrial phase in exchange with externally added ADP, under conditions quite close to a physiological state, i.e., when oxidative phosphorylation takes place. More than 30 years after the development of the method, here we aim to put the spotlight on it and to emphasize its versatile applicability in the most varied pathophysiological conditions, reviewing all the studies, in which we were able to observe what really happened in the cell thanks to the use of the "ATP detecting system" allowing the functional activity of the ANT-mediated ADP/ATP exchange to be measured.

Abstract
Alternatives to the use of conventional veterinary drugs in food-producing animals have gained attention, such as the use of natural products (NPs), mainly to soften the risks to the animal, the environment, and consumer's health. Although NPs have consistent advantages over conventional drugs, they cannot be considered risk free under food safety matters. In this way, this document presents a comprehensive overview of the importance of considering both the pharmacological and toxicological properties of the constituents of a NP from plants intending the standardization and regulation of its use in food-producing animals. Terpenes are the most diverse class of natural substances present in NP of vegetal origin with a broad range of biological activities that can be explored in veterinary science; however, certain plants and terpenes also have significant toxic effects, a fact that can harm the health of animals and consequently generate economic losses and risks for humans. In this context, this review gathered scientific data of vegetal species of importance to ethnoveterinary for food-producing animals, which produce terpenes, its biological effects, and their implications on food safety issues for consumers. For this, more than 300 documents were selected from different online scientific databases. The present data and discussion may contribute to the rational commercial exploration of this class of NPs in veterinary medicine.

Abstract
The present study was conducted in the Moroccan central Middle Atlas in order to inventory the plants used in the treatment of oral diseases, as well as to document possible risks of intoxication. Thus, 58 herbalists in the region were surveyed to gather ethnomedical information about the plants used in natural remedies preparation. The expression of the data obtained was achieved through the calculation of different quantitative indices, such as: use value (UV), family use value (FUV), relative frequency of citation (RFC), fidelity level (FL), informant consensus factor (ICF) and plant part value (PPV). 29 plants were inventoried, among which, Ruta montana L. has the highest use value (UV) and fidelity level (FL) for the treatment of gingivitis, respectively, 0.431 and 43.10. Marrubium vulgare L. has the highest citation frequency (RFC = 0.448). Whereas, Ammi visnaga (L.) Lam. had the highest value of the informant consensus factor (ICF = 0.846) as the most used species for the treatment of high number of oral pathologies and dental abscesses. Furthermore, the leaves generally prepared by decoction and administered by gargle constitute the most used part of the plant (PPV = 54.05). But, several plants recommended for the treatment of oral diseases are dangerous; in fact, Marrubium vulgare L., Atractylis gummifera L., Anacyclus pyrethrum L., Ruta montana L. and Peganum harmala L. were reported to be toxic by all the respondents. So, in spite of the virtues of medicinal plants, the toxic potential of some of them requires great vigilance in their therapeutic use.

Abstract
The adenosine nucleotide translocase (ANT) family of proteins are inner mitochondrial membrane proteins involved in energy homeostasis and cell death. The primary function of ANT proteins is to exchange cytosolic ADP with matrix ATP, facilitating the export of newly synthesized ATP to the cell while providing new ADP substrate to the mitochondria. As such, the ANT proteins are central to maintaining energy homeostasis in all eukaryotic cells. Evidence also suggests that the ANTs constitute a pore-forming component of the mitochondrial permeability transition pore (MPTP), a structure that forms in the inner mitochondrial membrane that is thought to underlie regulated necrotic cell death. Additionally, emerging studies suggest that ANT proteins are also critical for mitochondrial uncoupling and for promoting mitophagy. Thus, the ANTs are multifunctional proteins that are poised to participate in several aspects of mitochondrial biology and the greater regulation of cell death, which will be discussed here.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 253:112640. [PMID: 32027998 DOI: 10.1016/j.jep.2020.112640] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 01/19/2020] [Accepted: 01/30/2020] [Indexed: 05/28/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atractylis gummifera is a toxic plant widely used in Mediterranean traditional medicine against colds, dizziness, and headaches, as an antisyphilitic, against boils, as a purgative, emetic and deworming. All studies reported on this plant have been carried out either on the plant and its traditional uses, or on cases of poisoning by this plant. However, few pharmacological studies have readjusted the traditional uses of this plant. AIM OF THE STUDY The purpose of this article is to carry out a preliminary phytochemical study of Atractylis gummifera and to evaluate in vitro and in vivo antioxidant activity of its aqueous and organic extracts and to provide a complementary analysis of the mechanisms of action of the different antioxidant activity tests studied. METHODS The phytochemical study consisted of the hot and cold preparation of aqueous extracts: (decocted, infused, macerated), organic extracts: (methanolic, methanolic macerated, chloroformic, ethyl acetate, petroleum ether) and the determination of the secondary metabolites of these extracts. In addition, the biological study consisted of evaluating antioxidant activity in vitro by five different methods (H2O2 radical reduction, DPPH, ABTS, FRAP and RP) and in vivo by SOD and MDA assays. RESULTS The methanolic macerated is the richest in total polyphenols (102 ± 1.38 mg EAG/gE), tannins (144.09 ± 3.96 mg EC/gE) and flavonoids (17.25 ± 0.06 mg ER/gE). The same extract has the highest percentage to inhibit hydrogen peroxide (19.24 ± 1.10%) and the most potent reducing power of the ABTS radical (122.6 ± 0.63 mg ET/gE). We also noted that aqueous macerated has the most potent anti-radical activity of DPPH with an IC50 of 2.78 ± 1.03 μg/mL, the strongest reducing power of iron 96.15 ± 1.12 mg EAA/gE and which was confirmed by the FRAP test (102.5 ± 1.66 mg ET/gE). These results are in agreement with the in vivo study which showed an increase in SOD secretion in diabetic mice treated with aqueous macerated extract (904.26 ± 29.10 units/g liver and 714.16 ± 24.83 units/g kidney) and methanol macerated extract (813.61 ± 24.03 units/g liver and 719.46 ± 42.10 units/g kidney) with a statistically insignificant difference between these two extracts. Furthermore, we observed a return to normal MDA levels in mice treated with aqueous macerated extract (128.61 ± 15.76 nM/g liver and 103.18 ± 12.67 nM/g kidney) and methanol macerated extract (130.73 ± 10.73 nM/g liver and 34.28 ± 5.73 nM/g kidney). CONCLUSION The aqueous and organic extracts more particularly those prepared by aqueous and methanolic macerations are rich in polyphenols, flavonoids and tannins, and they represent a rich source of natural antioxidants, also they prevent lipid peroxidation and stimulate the secretion of the enzymatic antioxidant SOD.

Sevoflurane postconditioning improves spatial learning and memory ability involving mitochondrial permeability transition pore in hemorrhagic shock and resuscitation rats. Brain Behav 2020; 10:e01501. [PMID: 31833229 PMCID: PMC6955830 DOI: 10.1002/brb3.1501] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 11/21/2019] [Accepted: 11/22/2019] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Hemorrhagic shock induces the cognitive deficiency. Sevoflurane postconditioning has been documented to provide neuroprotection against ischemic-reperfusion injury by suppressing apoptosis. Mitochondrial permeability transition pore (mPTP) plays an important role in apoptosis, but it is unknown if the protective effect of sevoflurane postconditioning on hemorrhagic shock and resuscitation is associated with the change of mPTP opening. Hence, the aim of the study was to find out the precise mechanism of the sevoflurane postconditioning. METHODS Sprague Dawley rats were subjected to hemorrhage shock for 60 min and then exposed to 2.4% sevoflurane for 30 min at the instant of reperfusion. Additionally, an opener (atractyloside) or an inhibitor (cyclosporine A) of mPTP was used in the animal model before sevoflurane postconditioning. Rats were randomly assigned into groups of Sham, Shock, Shock+Sevoflurane, Shock+Atractyloside, Shock+Sevoflurane+Atractyloside, Shock+Cyclosporin A, and Shock+Sevoflurane+Cyclosporin A treatment. Rat behavior was assessed for 5 days by Morris water maze 72 hr after surgery, and then hippocampus CA1 region was immunohistochemically stained. Brains were harvested 24 hr after surgery to detect the protein expression levels of Bcl-2, Bax, and cytochrome C by Western blot, the changes of mPTP opening, and mitochondrial membrane potential (MMP). RESULTS We found that sevoflurane postconditioning significantly improved rats' spatial learning and memory ability, down-regulated the expression of Bax, cytochrome C, and caspase-3, up-regulated the expression of Bcl-2, decreased the mPTP opening, and increased the MMP. The neuroprotective effect of sevoflurane postconditioning was abolished by atractyloside, but cyclosporin A played the similar protective role as sevoflurane postconditioning. CONCLUSION These findings proved that sevoflurane postconditioning improved spatial learning and memory ability in hemorrhage shock and resuscitation rats, the mechanism of which may be related to block mPTP opening, increase MMP, and reduce neuron apoptosis in the hippocampus.

Abstract
Polygonum multiflorum Thunb. (PM), called Heshouwu in China, is a popular Chinese medicine in clinical practice. Several clinical studies have been conducted to evaluate the traditional therapeutic claims and to study the potential therapeutic activity of PM in dyslipidemia and neurodegenerative diseases, highlighting available clinical evidence. In recent years, reports on clinical adverse reactions of Raw Radix P. multiflorum (RPM) and P. multiflorum Praeparata (PMP) have been on the increase, especially with respect to liver injury. Most liver injury cases had been assessed for causality using RUCAM (Roussel Uclaf Causality Assessment Method) in this paper. However, the components of PM responsible for the reported hepatotoxic effects have not yet been identified. Moreover, many of the reports are contradictory, while studies on the mechanism involved in PM-induced liver damage are not comprehensive. This study was aimed at reviewing the status of research on liver injury due to PM, including clinical characteristics, risk factors, material basis research and mechanism of action, with a view to understanding PM-induced hepatotoxicity, and taking reasonable and effective measures to prevent it. In short, quality control is still one of the major safety problems in TCM drug safety concerns. The model of safety monitoring and risk management of PM drugs is not yet developed. Indeed, the characteristics and risk factors associated with PM require both proper understanding and control of the risk by strengthening standardization of clinical applications, basic science research, quality control in manufacturing, active monitoring methodology and enhancement of international communication and cooperation. Measures should also be encouraged and implemented to promote healthy development of the TCM industry.

Abstract
We report for the first time the isolation of 2-furyl(phenyl)methanol (5) from the chloroform extracts of the Atractylis gummifera roots. A. gummifera is a thistle belonging to the Asteraceae family that produces the ent-kaurane diterpenoid glycoside atractyloside (ATR). ATR (1) was isolated and chemically modified to obtain its aglycone atractyligenin (2) and the methylated derivatives ATR-OMe (3) and genine-OMe (4). The compounds 1-5 were structurally characterised and evaluated against the intracellular amastigote, cultured within macrophages, and the extracellular promastigote of Leishmania donovani, the protozoan parasite responsible for the highly infective disease visceral leishmaniasis, which is fatal if untreated. The 2-furyl(phenyl)methanol 5 exhibited notable activity against the promastigote.

Abstract
A new alkaloid pyrroloquinolone A (1), along with fifteen known compounds 2-16 were isolated from the petroleum ether, EtOAc and n-BuOH extracts of the whole plant Atractylis cancellata L. Their structures were elucidated on the basis of extensive spectroscopic analysis including 1D- and 2D-NMR and HR-ESI-MS techniques. This is the first report of alkaloids in the genus Atractylis. Some of the isolated compounds and extracts were evaluated for their antioxidant potential (scavenging activity of DPPH and ABTS radicals, and reducing Fe+3 and Cu+2 power assays) and acetylcholinesterase and butyrylcholinesterase inhibitory activities. Compounds 8 and 11 showed good antioxidant capacity compared to ascorbic acid, BHA, and BHT used as standards, whereas compounds 1 and 2 exhibited good anticholinesterase activities compared to galantamine used as standard.

Abstract
Mitochondrial carriers are proteins that shuttle a variety of metabolites, nucleotides and coenzymes across the inner mitochondrial membrane. The mitochondrial ADP/ATP carriers (AACs) specifically translocate the ATP synthesized within mitochondria to the cytosol in exchange for the cytosolic ADP, playing a key role in energy production, in promoting cell viability and regulating mitochondrial permeability transition pore opening. In Homo sapiens four genes code for AACs with different tissue distribution and expression patterns. Since AACs are dysregulated in several cancer types, the employment of known and new AAC inhibitors might be crucial for inducing mitochondrial-mediated apoptosis in cancer cells. Albeit carboxyatractyloside (CATR) and bongkrekic acid (BKA) are known to be powerful and highly selective AAC inhibitors, able to induce mitochondrial dysfunction at molecular level and poisoning at physiological level, we estimated here for the first time their affinity for the human recombinant AAC2 by in vitro transport assays. We found that the inhibition constants of CATR and BKA are 4 nM and 2.0 μM, respectively. For finding new AAC inhibitors we also performed a docking-based virtual screening of an in-house developed chemical library and we identified about 100 ligands showing high affinity for the AAC2 binding region. By testing 13 commercially available molecules, out of the 100 predicted candidates, we found that 2 of them, namely suramin and chebulinic acid, are competitive AAC2 inhibitors with inhibition constants 0.3 μM and 2.1 μM, respectively. We also demonstrated that chebulinic acid and suramin are "highly selective" AAC2 inhibitors, since they poorly inhibit other human mitochondrial carriers (namely ORC1, APC1 and AGC1).

Abstract
Herbal products have gained popularity over the past few decades. The reasons attributed to the rise in popularity are cheaper costs, easy availability, patient compliance and fewer side effects. However, liver toxicity following consumption of herbal remedies is on the increase. Thus, there is an urgent need to understand the mechanism of action of the herbal supplements on the liver. Occasionally, herbal supplements may also interact with conventional drugs. The present review focusses on a few herbs such as Aloe barbadensis, Atractylis gummifera, Centella asiatica, Mitragyna speciosa, Morinda citrifolia, Larea tridentata, Symphytum officinale, Teucrium chamaedrys and Xanthium strumarium, which are reported to cause hepatotoxicity in humans and animals. Prior knowledge on hepatotoxicity caused by herbs may be beneficial for clinicians and medical practitioners.

Abstract
Atractyloside (ATR) and carboxyatractyloside (CATR) are diterpene glycosides that are responsible for the toxicity of several Asteraceae plants around the world. Mediterranean gum thistle (Atractylis gummifera L.) and Zulu impila (Callilepis laureola DC.), in particular, are notoriously poisonous and the cause of many accidental deaths, some suicides and even some murders. There is no current method for measuring the two toxins in biological samples that meet the criteria of specificity required in forensic medicine. We have endeavored to fill this analytical gap. Analysis was carried out using a solid-phase extraction and a high-performance liquid chromatography coupled with high-resolution tandem mass spectrometry detection. The method was validated in the whole blood with quantification limits of 0.17 and 0.15 µg/L for ATR and CATR, respectively. The method was applied to a non-fatal case of intoxication with A. gummifera. To the best of the authors' knowledge, this is the first time that a concentration of ATR and CATR in blood (883.1 and 119.0 µg/L, respectively) and urine (230.4 and 140.3 µg/L, respectively) is reported. ATR and CATR were quantified in A. gummifera roots by the standard method addition (3.7 and 5.4 mg/g, respectively).

Abstract
Atractyloside (1) and carboxyatractyloside (2) are well-known inhibitors of the adenine nucleotide translocase (ANT) in mitochondria, thus effectively blocking oxidative phosphorylation. Structurally related derivatives atractyligenin (3), 2-O-β-D-glucopyranosyl-atractyligenin (4), 3'-O-β-D-glucopyranosyl-2'-O-isovaleryl-2β-(2-desoxy-atractyligenin)-β-D-glucopyranoside (5), and 2-O-β-D-glucopyranosyl-carboxyatractyligenin (6) were isolated from raw beans of Coffea L. and the impact of 1-6 on ANT activity was evaluated in isolated mitochondria. Among the coffee components, 6 significantly inhibited ANT activity leading to reduced respiration. Quantitative analysis in commercial coffees, experimental roastings of coffee, and model experiments using purified compound 6 consistently revealed a complete degradation during thermal treatment. In comparison, raw coffee extracts were found to contain high levels of 6, which are therefore expected to be present in food products enriched with raw coffee extracts. This implies the necessity of analytically controlling the levels of 6 in raw coffee extracts when used as additives for food products.

Abstract
Atractyloside (ATR) is found in many Asteraceae plants that are commonly used as medicinal herbs in China and other eastern Asian countries. ATR binds specifically to the adenine nucleotide translocator in the inner mitochondrial membrane and competitively inhibits ADP and ATP transport. The toxicity of ATR in medical herbs can be reduced by hydrothermal processing, but the mechanisms of ATR degradation are not well understood. In this study, GC-MS coupled with SPE and TMS derivatisation was used to detect ATR levels in traditional Chinese medicinal herbs. Our results suggest that ATR molecules were disrupted by decomposition, hydrolysis and saponification after heating with water (decoction) for a long period of time. Hydrothermal processing could decompose the endogenous toxic compounds and also facilitate the detoxification of raw materials used in the Chinese medicine industry.

Abstract
BACKGROUND Herbal and dietary supplements are commonly used throughout the World. There is a tendency for underreporting their ingestion by patients and the magnitude of their use is underrecognised by Physicians. Herbal hepatotoxicity is not uncommonly encountered, but the precise incidence and manifestations have not been well characterised. AIMS To review the epidemiology, presentation and diagnosis of herbal hepatotoxicity. This review will mainly discuss single ingredients and complex mixtures of herbs marketed under a single label. METHODS A Medline search was undertaken to identify relevant literature using search terms including 'herbal', 'herbs', 'dietary supplement', 'liver injury', 'hepatitis' and 'hepatotoxicity'. Furthermore, we scanned the reference lists of the primary and review articles to identify publications not retrieved by electronic searches. RESULTS The incidence rates of herbal hepatotoxicity are largely unknown. The clinical presentation and severity can be highly variable, ranging from mild hepatitis to acute hepatic failure requiring transplantation. Scoring systems for the causality assessment of drug-induced liver injury may be helpful, but have not been validated for herbal hepatotoxicity. Hepatotoxicity features of commonly used herbal products, such as Ayurvedic and Chinese herbs, black cohosh, chaparral, germander, greater celandine, green tea, Herbalife, Hydroxycut, kava, pennyroyal, pyrrolizidine alkaloids, skullcap, and usnic acid, have been individually reviewed. Furthermore, clinically significant herb-drug interactions are also discussed. CONCLUSIONS A number of herbal medicinal products are associated with a spectrum of hepatotoxicity events. Advances in the understanding of the pathogenesis and the risks involved are needed to improve herbal medicine safety.

Abstract
The use of plants as a source of palliative or cure for pathological conditions is quite common worldwide. Xanthium spinosum (Asteraceae), popularly known in Brazil as 'espinho de carneiro', is an annual weed from South America, which has been used by empiric medicine to treat neoplasias. Owing to the extensive use of the above-mentioned plant and to the lack of reports about the real effects of its infusion, current study evaluated the genotoxic potential of its aqueous extract at concentrations 0.02 g L-1, 0.1 g L-1 and 0.2 g L-1 by fish micronucleus test and by comet human leukocytes assay. The micronucleus test featured at least 50 cells with micronuclei to every 2,000 cells scored, as a mutagenic parameter. The comet assay was used as a parameter for assessing the level of cell damage and the damage index. Since no significant changes in strain cells exposed to the aqueous extract in the comet and micronucleus assays were reported, it seems that no genotoxicity evidence is extant at the concentrations and in the assays performed.

Abstract
We report the first complete structure elucidation of the ent-kaurane diterpenoid glycoside atractyloside (1) by means of NMR and X-ray diffractometry techniques. Extensive one- and two-dimensional NMR experiments were employed to assign the proton and carbon signals of 1, and crystallography experiments established the configurations of all stereogenic centers. Furthermore, we present a novel semisynthetic route for the preparation of the highly cytotoxic aglycone derivative of 1, 15-didehydroatractyligenin methyl ester (3). All compounds were tested for their antibiotic activity against Enterococcus faecalis, Escherichia coli, and several strains of Staphylococcus aureus, including fluoroquinolone-resistant (SA1199B) and two epidemic MRSA (EMRSA-15 and -16) strains. Compound 3 exhibited moderate activity against all of the Staph. aureus strains with an MIC value of 128 mg/L.

Abstract
Atractyloside is the principal naturally occurring active ingredient in ethnomedicines and animal grazing forage. Evidence that atractyloside can induce opening of the mitochondrial permeability transition pore (mPTP) indicates that mitochondrial mechanisms may play an important role in pathophysiological lesions of the heart, liver and kidney after atractyloside poisoning. Therefore, in this study we investigated the association of atractyloside-induced mitochondrial damage in arteriolar smooth muscle cells (ASMCs) with contractile reaction. Atractyloside led to depolarized and swollen or damaged ASMC mitochondria, which might be related to the concentration-dependent induction of mPTP opening. Relative ATP content in ASMCs was significantly reduced by 48%, 63% and 66% of control when cells were treated with 7.5, 10, and 15 µm atractyloside for 10 min, respectively, and ASMCs were hyperpolarized. In addition, the contractile responsiveness of ASMCs was eventually weakened. These results suggest that atractyloside has a toxic effect on vasoreactivity, which is possibly related to mitochondrial damage.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atractylis gummifera L. and Centaurea ornata Willd. are locally marketed herbal remedies, even though in Spain it is forbidden to sell toxic plants like Atractylis gummifera. Intoxications in Spain are mainly due to accidental substitution of Centaurea ornata with Atractylis gummifera which may be fatal. AIM OF STUDY The aim of this article is to analyse the current use and marketing of Atractylis gummifera and Centaurea ornata in Badajoz and analyse the ethnopharmacological relevance of two recent cases of Atractylis gummifera poisoning. BACKGROUND AND METHODS An ethnopharmacological survey was conducted in the area where one of the poisoned patients lives and in Guadiana del Caudillo. The use, knowledge and naming of the species involved in the poisoning was assessed. This information was complemented with an exhaustive search in Spanish ethnobotanical works on the ethnopharmacological uses of both species. RESULTS Intoxications are due to species' substitutions. The two species are similar in name and use in the area, and both are locally marketed. AG is mainly used to heal wounds and calcaneal spurs, and CO to treat gastric ulcers and wounds. CONCLUSIONS New intoxications are likely since consumers often have limited knowledge of the plants they consume. Also, it is common to think that all medicinal plants are harmless. As the use of Atractylis gummifera seems to increase in the area, preventive measures need to be taken.

Abstract
Atractylis gummifera L., a poisonous thistle responsible for frequent and sometimes mortal poisonings is known in Mediterranean region and in occident as this plant is used in alternative medicine. The clinical and biological data of four cases of poisoning in Morocco by Atractylis gummifera L. reported and discussed in this study will have to help to review this poisoning in order to inform better and to take care of the poisoned persons. Also this study may contribute to prevent the use of this plant in traditional medicine.

Abstract
Our understanding of the many different causes of hypoglycemia has vastly expanded in recent years. Most hypoglycemic disorders in infants and children are due to defects in the metabolic systems involved in fasting adaptation or the hormone control of these systems. As a result of these defects, infants and children have an abnormal adaptation to fasting, which results in hypoglycemia. The "critical sample" allows one to assess the integrity of the fasting systems when hypoglycemic. An understanding of the pathophysiology of these disorders establishes a foundation for a rational approach in evaluating the etiology of the hypoglycemia and developing the most appropriate management plan.

Abstract
BACKGROUND Atractylis gummifera is poisonous and its ingestion causes illness, characterized principally by hepatorenal injury, often fatal. The toxicity of this plant to the fetus is not known. We report a case of poisoning during pregnancy. CASE REPORT A 28 year-old woman was admitted to our intensive care unit for Atractylis gummifera poisoning during her 24th week of pregnancy. She showed gastrointestinal symptoms, impaired consciousness, hypoglycemia, hepatic cytolysis and decreased factor V blood levels. The mother recovered after symptomatic treatment. A healthy boy was delivered vaginally at 39 weeks and his clinical findings and laboratory results were normal at birth and a week later. DISCUSSION Poisoning by Atractylis gummifera has not previously been reported during pregnancy. The favorable course of our patient and her infant do not rule out possible fetal damage from which he recovered, as his mother did.

Abstract
A significant number of herbal products have been associated with hepatotoxicity. Attribution of liver injury to a specific herbal pro-duct may be difficult. There are few clinical or laboratory manifestations that specifically suggest that liver injury is the result of aspecific herbal. Compounding this difficulty is that the patient may have liver disease from another cause, may be consuming other potentially hepatotoxic products, or may be using a contaminated herbal product. The most important clue often is the temporal relationship between initiation of the herbal product and the appearance of liver injury; of equal importance is the resolution of the injury following withdrawal of the herbal product.
