Zhang N, An B, Zhao L, Zhao D, Lv B, Liu S. Investigation of the mechanism of nephrotoxicity of nux-vomica by PTGS2/CYP2C9-mediated arachidonic acid pathway and Jian Pi Tong Luo compound's protective effect. Biomed Chromatogr 2024; 38:e5859. [PMID: 38618996 DOI: 10.1002/bmc.5859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 02/03/2024] [Accepted: 02/16/2024] [Indexed: 04/16/2024]
Abstract
The clinical effectiveness of nux-vomica in treating rheumatism and arthralgia is noteworthy; however, its nephrotoxicity has sparked global concerns. Hence, there is value in conducting studies on detoxification methods based on traditional Chinese medicine compatibility theory. Blood biochemistry, enzyme-linked immunosorbent assay, and pathological sections were used to evaluate both the nephrotoxicity of nux-vomica and the efficacy of the Jian Pi Tong Luo (JPTL) compound in mitigating this toxicity. Kidney metabolomics, using ultra-high-performance liquid chromatography-quadrupole-time-of-flight-MS (UPLC-Q-TOF-MS), was applied to elucidate the alterations in small-molecule metabolites in vivo. In addition, network pharmacology analysis was used to verify the mechanism and pathways underlying the nephrotoxicity associated with nux-vomica. Finally, essential targets were validated through molecular docking and western blotting. The findings indicated significant nephrotoxicity associated with nux-vomica, while the JPTL compound demonstrated the ability to alleviate this toxicity. The mechanism potentially involves nux-vomica activating the "PTGS2/CYP2C9-phosphatidylcholine-arachidonic acid metabolic pathway." This study establishes a scientific foundation for the clinical use of nux-vomica and lays groundwork for further research and safety assessment of toxic Chinese herbal medicines.

Adherence to the Mediterranean Diet and its association with gastric cancer: health benefits from a Planeterranean perspective. J Transl Med 2024; 22:483. [PMID: 38773621 PMCID: PMC11110331 DOI: 10.1186/s12967-024-05176-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 04/05/2024] [Indexed: 05/24/2024] Open
Abstract
The Mediterranean Diet (MD) has garnered increasing attention for its potential protective effects against gastric cancer (GC). The MD's rich content of antioxidants, polyphenols, and other bioactive compounds contributes to its ability to modulate gene expression, inhibit tumor growth, and regulate apoptosis. Studies have shown significant reductions in inflammatory markers such as C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) among individuals adhering to the MD, suggesting its pivotal role in mitigating chronic inflammation-associated with cancer development. Furthermore, the MD's anti-angiogenic properties, particularly in components like olive oil, red wine, fish, and tomatoes, offer promising avenues for reducing GC risk by inhibiting tumor angiogenesis. Additionally, the MD's influence on intestinal microbiota composition underscores its potential in maintaining immune homeostasis and reducing systemic inflammation, factors crucial in GC prevention. Despite challenges such as variability in dietary adherence scoring systems and the need for further gender and geographical-specific studies, evidence supports the MD as a cost-effective and holistic approach to GC prevention. Emphasizing the role of nutrition in public health is a promising strategy with broad implications for global health and cancer prevention initiatives. Therefore, this review explores the multifaceted impacts of the MD on GC prevention, delving into its anti-inflammatory, anti-angiogenic, and molecular mechanisms.

[PMID: 37997986 PMCID: PMC10669091 DOI: 10.3390/biology12111387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 10/26/2023] [Accepted: 10/28/2023] [Indexed: 11/25/2023]
Abstract
Genista tridentata (L.) Willk., known as "prickled broom", is a Leguminosae (Fabaceae) species native to the Iberian Peninsula, Morocco, Algeria, and Tunisia. It is used in folk medicine as an anti-inflammatory, for gastrointestinal and respiratory disorders, rheumatism, and headaches, to lower blood pressure, against hypercholesterolemia and hyperglycemia. This study aimed to systematically review the literature on the bioactivities and phytochemical profile of Genista tridentata to understand its pharmacological potential. For this, four electronic databases (PubMed, GoogleScholar, Repositórios Cientificos de Acesso Aberto de Portugal (RCCAP), and ScienceDirect) were searched from inception up to 31 December 2022. From a total of 264 potentially eligible studies considered for screening, 34 papers were considered eligible for this systematic review. The sampling included 71 extracts, collected mainly in Portugal. Genista tridentata extracts present a high level of flavonoids and phenolic compounds. The flowers and aerial parts of the plant were the most studied, and aqueous extracts were the most used. The results predict a high potential for the application of Genista tridentata as a new source of natural antioxidants and preservatives for the food industry with subsequent health benefits, such as the production of nutraceuticals. Moreover, the results indicate that the plant can be collected at all seasons of the year, which represents a benefit for the industry.

Abstract
OBJECTIVES This scoping review aims to present flavonoid compounds' promising effects and possible mechanisms of action on potential therapeutic targets in the SARS-CoV-2 infection process. METHODS A search of electronic databases such as PubMed and Scopus was carried out to evaluate the performance of substances from the flavonoid class at different stages of SARS-CoV-2 infection. RESULTS The search strategy yielded 382 articles after the exclusion of duplicates. During the screening process, 265 records were deemed as irrelevant. At the end of the full-text appraisal, 37 studies were considered eligible for data extraction and qualitative synthesis. All the studies used virtual molecular docking models to verify the affinity of compounds from the flavonoid class with crucial proteins in the replication cycle of the SARS-CoV-2 virus (Spike protein, PLpro, 3CLpro/ MPro, RdRP, and inhibition of the host's ACE II receptor). The flavonoids with more targets and lowest binding energies were: orientin, quercetin, epigallocatechin, narcissoside, silymarin, neohesperidin, delphinidin-3,5-diglucoside, and delphinidin-3-sambubioside-5-glucoside. CONCLUSION These studies allow us to provide a basis for in vitro and in vivo assays to assist in developing drugs for the treatment and prevention of COVID-19.

Abstract
In this study, methanol and water-methanol extracts of borage (Borago officinalis) herb dried using various methods were analysed for their phenolic profile and biological activity. Twelve compounds, including flavonoids (astragalin, kaempferol 4-glucoside, rutoside, and vitexin) and phenolic acids (caffeic, chlorogenic, 3,4-dihydroxyphenylacetic, ferulic, p-hydroxybenzoic, protocatechuic, rosmarinic, and syringic), were determined qualitatively and quantitatively in B. officinalis extracts by the HPLC-DAD method. The highest total flavonoid content was confirmed for the methanol extract from the hot-air-dried herb, while the methanol extract from the air-dried herb was most abundant in phenolic acids. The results of in vitro tests on human keratinocytes (HaCaT) and fibroblasts (BJ) showed that the extracts were able to reduce the intracellular level of reactive oxygen species in skin cells. Tests performed to assess inhibition of protein denaturation, lipoxygenase activity, and proteinase activity demonstrated that borage extracts have anti-inflammatory properties. In addition, the methanol extract of the herb dried in a convection oven showed the strongest inhibition of both collagenase and elastase activity, which is indicative of anti-ageing properties. The results show that the borage extracts are a source of valuable bioactive compounds with beneficial properties in the context of skin cell protection.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating side effect of many common anti-cancer agents that can lead to dose reduction or treatment discontinuation, which decrease chemotherapy efficacy. Long-term CIPN can interfere with activities of daily living and diminish the quality of life. The mechanism of CIPN is not yet fully understood, and biomarkers are needed to identify patients at high risk and potential treatment targets. Metabolomics can capture the complex behavioral and pathophysiological processes involved in CIPN. This chapter is to review the CIPN metabolomics studies to find metabolic pathways potentially involved in CIPN. These potential CIPN metabolites are then investigated to determine whether there is evidence from studies of other neuropathy etiologies such as diabetic neuropathy and Leber hereditary optic neuropathy to support the importance of these pathways in peripheral neuropathy. Six potential biomarkers and their putative mechanisms in peripheral neuropathy were reviewed. Among these biomarkers, histidine and phenylalanine have clear roles in neurotransmission or neuroinflammation in peripheral neuropathy. Further research is needed to discover and validate CIPN metabolomics biomarkers in large clinical studies.

Abstract
Plants produce polyphenols, which are considered highly essential functional foods in our diet. They are classified into several groups according to their diverse chemical structures. Flavanoids, lignans, stilbenes, and phenolic acids are the four main families of polyphenols. Several in vivo and in vitro research have been conducted so far to evaluate their health consequences. Polyphenols serve a vital function in the protection of the organism from external stimuli and in eliminating reactive oxygen species (ROS), which are instigators of several illnesses. Polyphenols are present in tea, chocolate, fruits, and vegetables with the potential to positively influence human health. For instance, cocoa flavan-3-ols have been associated with a decreased risk of myocardial infarction, stroke, and diabetes. Polyphenols in the diet also help to improve lipid profiles, blood pressure, insulin resistance, and systemic inflammation. Quercetin, a flavonoid, and resveratrol, a stilbene, have been linked to improved cardiovascular health. Dietary polyphenols potential to elicit therapeutic effects might be attributed, at least in part, to a bidirectional association with the gut microbiome. This is because polyphenols are known to affect the gut microbiome composition in ways that lead to better human health. Specifically, the gut microbiome converts polyphenols into bioactive compounds that have therapeutic effects. In this review, the antioxidant, cytotoxicity, anti-inflammatory, antihypertensive, and anti-diabetic actions of polyphenols are described based on findings from in vivo and in vitro experimental trials. PRACTICAL APPLICATIONS: The non-communicable diseases (NCDs) burden has been increasing worldwide due to the sedentary lifestyle and several other factors such as smoking, junk food, etc. Scientific literature evidence supports the use of plant-based food polyphenols as therapeutic agents that could help to alleviate NCD's burden. Thus, consuming polyphenolic compounds from natural sources could be an effective solution to mitigate NCDs concerns. It is also discussed how natural antioxidants from medicinal plants might help prevent or repair damage caused by free radicals, such as oxidative stress.

Abstract
BACKGROUND Chronic cutaneous pain has a substantial negative impact on quality of life (QoL). Dermo-cosmetics can support therapies for treatment of chronic skin diseases, providing symptomatic relief from chronic cutaneous pain and improved QoL. OBJECTIVES To assess the global tolerance and efficacy of a dermo-cosmetic spray containing Rhealba® Oat Plantlet and Uncaria tomentosa extracts in reducing cutaneous pain when used as a monotherapy or in association with drug or dermo-cosmetic treatments in patients with an underlying skin pathology. METHODS Patients aged ≥1 month with a cutaneous pain level ≥3 and an underlying skin pathology were provided with the spray to use up to six times daily for 6-8 weeks. Immediate effect on cutaneous pain and patient satisfaction were assessed after the first application. Global efficacy and tolerance, reduction in symptoms, improvement in QoL, pain reduction and patient overall satisfaction were assessed after 6-8 weeks. RESULTS Immediately after the first application, significant reductions in cutaneous pain were observed across all age groups (P < 0.0001), with 94% of patients reporting a reduction in pain. After 6-8 weeks, global tolerance was rated 'very good' or 'good' for 97% of patients, and the spray was efficacious in 95% of patients. Patient satisfaction with the efficacy of the spray was 95%. QoL scores improved in 86% and 94% of patients aged ≥12 and <12 years, respectively. Findings were similar across underlying pathology and therapy types (monotherapy or in association with another therapy). CONCLUSIONS The spray was well-tolerated and efficacious in providing symptom relief in patients with mild-to-moderate cutaneous pain, irrespective of the underlying pathology or therapy type.

Abstract
Aspidosperma pyrifolium is used in traditional medicine to treat inflammatory disorders. The aim of the study was to perform phytochemical characterization and evaluate the anti-inflammatory, anti-nociceptive and acute toxicity effects of the total alkaloid fraction (TAF-Ap) from stem barks. Two monoterpenic indole alkaloids were isolated by high performance liquid chromatography coupled with mass spectrometry (HPLC-MS) and the structural elucidation was performed using 1D and 2D NMR analysis. As for toxicity, no animals died at 50 mg kg−1 and this concentration presented mild sedation and forced breathing within the first 24 h. The lethal dose capable of killing 50% of the animals (LD50) was estimated to be 160 mg kg−1. In the pharmacological tests, the models used were 1% carrageenan-induced paw edema and peritonitis, 1% formalin-induced nociception and 1% acetic acid-induced abdominal writhing in Swiss mice. The study made it possible to isolate 15-methoxyaspidospermine and 15-methoxypyrifolidine, corroborating the results of pharmacological assays, which showed anti-inflammatory and analgesic potential, especially at 30 mg kg−1 (p < 0.001). Thus, the species was shown to be a promising source of active substances, with special attention paid to its toxicological potential.

Abstract
Phenolic compounds, widespread in plants, are a necessary part of the human regimen due to their antioxidant and pro-oxidative properties. Naturally, phenolics structurally range from a very simple phenolic molecule moiety to an intricate polymer. For decades, phenolic compounds have gained pronounced attention because of their protective effects against degenerative disorders such as inflammation, diabetes and cancer. Physico-chemical properties (eg, solubility) restricted their bioactivity and also limited their usage as nutraceutical ingredients. However, encapsulation technology like liposomal formulations has been developed for the delivery of phenolic compounds without affecting their original aesthetic and organoleptic property. Hence, this review outlines the antioxidant and pro-oxidative properties of phenolic compounds and focuses on biological activity reports of flavonoids and phenolic acids as antidiabetic, anti-inflammatory and anticancer agents. Also, the delivery applications of phenolic compounds as liposomes are discussed with few examples.

Design and Synthesis In Silico Drug-like Prediction and Pharmacological Evaluation of Cyclopolymethylenic Homologous of LASSBio-1514. Molecules 2021; 26:4828. [PMID: 34443416 PMCID: PMC8399892 DOI: 10.3390/molecules26164828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 07/28/2021] [Accepted: 07/29/2021] [Indexed: 12/03/2022] Open
Abstract
Acylhydrazones are still an important framework to the design of new bioactive compounds. As treatment of chronic pain represents a clinical challenge, we decided to modify the structure of LASSBio-1514 (1), previously described as anti-inflammatory and analgesic prototype. Applying the homologation as a strategy for molecular modification, we designed a series of cyclopentyl- (2a-e), cyclobutyl- (3a-e), and cyclopropylacylhydrazones (4a-e) that were synthetized and evaluated in murine models of inflammation and pain. A comparison of their in silico physicochemical and drug-like profile was conducted, as well as their anti-inflammatory and analgesic effect. Compounds 4a (LASSBio-1755) and 4e (LASSBio-1757) displayed excellent in silico drug-like profiles and were identified as new analgesic lead-candidates in acute and chronic model of pain, through oral administration.

Abstract
Parkinson's disease (PD) is a chronic and progressive neurodegenerative disorder characterized by the progressive death of dopaminergic neurons in the substantia nigra pars compacta (SNc). PD is a multifactorial disorder, with several different factors being suggested to play a synergistic pathophysiological role, including oxidative stress, autophagy, underlying pro-inflammatory events and neurotransmitters abnormalities. Overall, PD can be viewed as the product of a complex interaction of environmental factors acting on a given genetic background. The importance of this subject has gained more attention to discover novel therapies to prevent as well as treat PD. According to previous research, drugs used to treat PD have indicated significant limitations. Therefore, the role of flavonoids has been extensively studied in PD treatment. Quercetin, a plant flavonol from the flavonoid group, has been considered as a supplemental therapy for PD. Quercetin has pharmacological functions in PD by controlling different molecular pathways. Although few studies intended to evaluate the basis for the use of quercetin in the context of PD have been conducted so far, at present, there is very little evidence available addressing the underlying mechanisms of action. Various principal aspects of these treatment procedures remain unknown. Here, currently existing knowledge supporting the use of quercetin for the clinical management of PD has been reviewed.

Incorporation of indomethacin into a mesoporous silica nanoparticle enhances the anti-inflammatory effect Indomethacin into a mesoporous silica. Eur J Pharm Sci 2021; 157:105601. [PMID: 33115672 DOI: 10.1016/j.ejps.2020.105601] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 10/09/2020] [Accepted: 10/12/2020] [Indexed: 01/21/2023]
Abstract
PURPOSE We evaluated the analgesic, anti-inflammatory and toxicological effects of indomethacin incorporated into mesoporous silica nanoparticles (IND+NP). METHODS Nociception was evaluated by the formalin assay. The anti-inflammatory potential was assessed by cell migration and paw edema assays, modulation of nitric oxide and cytokines (IL-6, IL-10 and TNF-α) by macrophages production. Toxicity was evaluated in peritoneal macrophages and by the locomotion assay and assessment of gastric injuries, presence of occult blood and hepatic and renal markers. RESULTS IND+NP reduced nociception during phases 1 by 53% and 2 by 79% of the formalin assay and the influx of peritoneal cells by 94%, indicating an analgesic and anti-inflammatory effect more efficiently than indomethacin alone. Indomethacin, but not IND+NP, caused macroscopic gastric injuries, the presence of fecal occult blood, and an increase of ALT levels. In the paw edema assay, IND+NP reduced edema by 21%. IND+NP has no effect on the LPS-induced production of nitric oxide, IL-6, IL-10 and TNF-α on no cytotoxic concentrations. CONCLUSIONS The incorporation of indomethacin into mesoporous silica nanoparticles effectively increased the activity of the drug observed in the formalin and cell migration assays and prevented the gastric and hepatic damage associated with its use.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Since the dawn of time, medicinal and aromatic plants (AMPs) represent a precious heritage for humanity, especially in developing countries, who exploit their virtues in traditional pharmacopoeia to cope with health problems such as diabetes, kidney stones, ulcer, and digestive disorders. Petroselinum sativum Hoffm. belongs to Apiaceae family. It is traditionally used to treat arterial hypertension, diabetes, cardiac disease, renal disease, and recently reported as a plant endowed with a female anti-infertility effect. AIM OF THE STUDY This study aims to evaluate the in vivo effect of hydro-ethanolic extract and polyphenols of Petroselinum sativum Hoffm. on cholesterol, protein and estrogen levels, and characterize the chemical composition of polyphenolic fraction. In addition, acute toxicity and anti-inflammatory activity of tested extract was also investigated. MATERIALS AND METHODS Chemical composition of polyphenolic fraction was determined using High-Performance Liquid Chromatography with Diode-Array Detection (HPLC-DAD). First, toxicological investigations including sub-acute toxicity were performed by measuring animals' weights daily for four weeks. Afterwards, histopathological examination of livers and kidneys, and serum assay of ASAT and ALAT were also checked. Next, the acute in vivo anti-inflammatory study of the hydro-ethanolic extract and polyphenols of Petroselinum sativum Hoffm. versus Indomethacin was conducted. Furthermore, we evaluated the estrogenic effect of its hydro-ethanolic extract and the polyphenolic fraction following biochemical assays for the determination of proteins, cholesterol and estrogen levels. RESULTS The results revealed the presence of some phenolic compounds mainly ferulic acid, gallic acid and quercetin. Petroselinum sativum Hoffm. extracts also showed no evidence of hepatotoxicity nor nephrotoxicity, with remarkable anti-inflammatory activity, as well as a significant estrogenic effect compared to negative control. CONCLUSION This study provides a scope of the potential use of Petroselinum sativum Hoffm. extracts in counteracting female infertility issues.

Abstract
Abstract
Background
Curcumin, quercetin and rutin are flavonoids having strong antioxidant potential, individually used in treatment of numerous ailments. The safety assessment of each of them is already established but no toxicological assessment has been done that would guarantee the safe use of these three flavonoids when used as a polyherbal combination (PHC). The aim of this study to evaluate the possible toxicological effect of polyherbal combination of these three flavonoids in female Swiss albino mice.
Methods
In acute toxicity study, the oral dose of poly herbal combination was administered to four groups stepwise in single dose and general behaviour, adverse effects and mortality were determined up to 14 days and compared to normal group. In sub-acute study, the tested poly herbal combination was administered orally for 28 days to the four experimental groups and their body weight was measured each alternate day from the first day of dosing. On 29th day the final body weight was recorded and euthanized by using thiopentone sodium, blood was collected and later haematological, lipid profile, biochemical parameter was evaluated and compared to normal group.
Result
In acute toxicity study, no abnormal general behaviour, adverse effects were reported. No significant changes were reported in body weight, haematological, lipid profile, biochemical parameter in sub-acute toxicity study. No mortality was reported in both the study. Histopathological examination revealed no alterations in clinical signs or organ weight at any dose.
Conclusion
The result concludes that the oral administration of Polyherbal combination did not produce any significant toxic effect in swiss albino mice. Hence, the Polyherbal combination can be utilized safely for therapeutic use.

Research on the mechanism of Chinese herbal medicine Radix Paeoniae Rubra in improving chronic pelvic inflammation disease by regulating PTGS2 in the arachidonic acid pathway.

Abstract
Radix Paeoniae Rubra (RPR) is a traditional Chinese medicine with anti-inflammatory effects that has been used in chronic pelvic inflammation disease (CPID) therapy. However, research on the mechanism of RPR in CPID therapy is lacking. Here, we used a network pharmacology method to screen targets and found that the PTGS2 target in the arachidonic acid (AA) pathway was significantly related to CPID. Then, regarding the molecular mechanism, it was further confirmed that RPR may reduce the development of CPID by regulating the PTGS2 target. The CPID rat model was established by mixed bacterial infection. We verified the expression of PTGS2 by immunohistochemical analysis, western blotting assays to detect the expression of PTGS2 protein, and polymerase chain reaction detection of PTGS2 mRNA expression. It was observed that the PTGS2 target decreased significantly after RPR administration at different doses. It is suggested that RPR can reverse the abnormal expression of PTGS2 in CPID rats. We believe that RPR is effective in the treatment of CPID, and RPR can reduce the inflammatory symptoms of CPID by regulating the level of PTGS2 in the AA pathway.

Abstract
Neuropathic pain (NP) is the result of irregular processing in the central or peripheral nervous system, which is generally caused by neuronal injury. The management of NP represents a great challenge owing to its heterogeneous profile and the significant undesirable side effects of the frequently prescribed psychoactive agents, including benzodiazepines (BDZ). Currently, several established drugs including antidepressants, anticonvulsants, topical lidocaine, and opioids are used to treat NP, but they exert a wide range of adverse effects. To reduce the burden of adverse effects, we need to investigate alternative therapeutics for the management of NP. Flavonoids are the most common secondary metabolites of plants used in folkloric medicine as tranquilizers, and have been claimed to have a selective affinity to the BDZ binding site. Several studies in animal models have reported that flavonoids can reduce NP. In this paper, we emphasize the potentiality of flavonoids for the management of NP.

Abstract
Background:Genista tridentata L. is an endemic species from the Iberian Peninsula used in Portuguese traditional medicine to treat inflammation-related diseases; this and other health-promoting effects are usually associated with the flavonoids produced by this species. In fact, anti-inflammatory properties were established for several of these flavonoid derivatives. Methods: A careful survey of the reported data, using mainly the Scopus database and Genista tridentata and Pterospartum tridentatum as keywords, was done. We have examined the papers involving the plant and those about the most relevant flavonoids anti-inflammatory activity. Results: The literature survey demonstrates that species are used to treat several health problems such as antihyperglycemia, hypertension, and inflammatory episodes. It was also possible to establish its richness in flavonoid derivatives, from which several are potential anti-inflammatory agents. Conclusions: From our described and discussed analysis, it can be concluded that Genista tridentata is an excellent source of bioactive flavonoids. Moreover, its traditional use to treat inflammation episodes may be due to its flavonoid content, from which genistein, biochanin A, rutin, and daidzein can be emphasized.

Abstract
BACKGROUND AND OBJECTIVE The fortification of bakery products by new materials that attain various goals is considered a challenging that finally gains useful health amelioration. This study was planned to assess the effect of incorporation of solar dried prickly pear peels powder in qaraqeesh (Egyptian cookies) with respect to increase shelf life, sensory palatability and nutritional value. Prickly pear cactus (Opuntia ficus-indica) beside distributed in arid and semiarid regions proved to have phytochemical compounds with high antioxidants capacity. MATERIALS AND METHODS Fungi colonies were isolated from prickly pear peels. Three levels (1, 3 and 5%) of dried peels powder were added to wheat flour along with other ingredients to make cookies samples. Mycological analysis was assessed in yeast with the three concentrations of peels powder as well as the fresh peels and negative control. The total phenolics, flavonoids, tannins, anthocyanins and carotenoids as well as the antioxidant activity were evaluated in fresh and dried cactus peels. RESULTS Findings showed that the prickly pear peels powder (PPPP) antioxidant activity was not much affected by the solar drying conditions. The effect of different extracting solvents at different polarties and pH on the phenolic and flavonoids contents of PPPP was studied. Aflatoxins production by aflatoxignicity A. flavus (ATCC 28542) was inhibited by adding different concentrations of PPPP to cookies. Sensory evaluation of fortified cookies was done. All the evaluated characteristics of cookies were given nearly the same values for all levels of dried peels powder. CONCLUSION Addition of 5% dried cactus peel had lower overall quality and color than the control. Adding 3% of PPPP to cookies (qaraqeesh) showed the highest sensory score. Dried cactus peels may improve quality, nutritional value and shelf life of cookies.

Abstract
Rutin is one of the most important flavonoids with poor bioavailability. This work aimed at addressing the issue of poor biopharmaceutical performance of rutin by applying a combination of complexation with secondary processing into tablets. Mechanical activation was the most suitable method of rutin complex formation with (2-hydroxypropyl)-β-cyclodextrin (HP-β-CD), while the β-cyclodextrin (β-CD) complex successfully formed by kneading with an ethanol/water mixture. Complexation was confirmed by thermal analysis, powder X-ray diffraction and vibrational spectroscopy. Dynamic vapour sorption showed that stability of powders at high humidity conditions was satisfactory, however, the β-CD complex retained around 8% of moisture. The complexes were compacted with or without tricalcium phosphate (TRI-CAFOS) filler at a range of compression pressures (19-113 MPa). The best tabletability was determined for rutin/HP-β-CD, compressibility for the TRI-CAFOS blends with complexes and compactibility for the rutin/HP-β-CD + TRI-CAFOS mix. Dissolution studies showed quicker and more complete dissolution (pH 1.2) of rutin/HP-β-CD tablets, however the compacts comprising the filler were superior than pure complexes. The tablets manufactured in this study appear to be promising delivery systems of rutin and it is recommended to combine rutin/HP-β-CD with TRI-CAFOS and compact at 38-76 MPa.

[PMID: 31751650 DOI: 10.1016/j.jep.2019.112414] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Revised: 06/20/2019] [Accepted: 11/17/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The research into bioactive natural products originating from medicinal plants, fungi and other organisms has a long history, accumulating abundant and diverse publications. However no quantitative literature analysis has been conducted so far. AIM OF THE STUDY Here we analyze the bibliometric data of ethnopharmacology literature and relate the semantic content to the publication and citation data so that the major research themes, contributors, and journals of different time periods could be identified and evaluated. MATERIALS AND METHODS Web of Science (WoS) was searched to identify relevant publications. The Analyze function of WoS and bibliometric software (VOSviewer) were utilized to perform the analyses. RESULTS Until the end of November 2018, 59,576 publications -linked to 'ethnopharmacology' indexed by WoS, published since 1958 in more than 5600 journals, and contributed by over 20,600 institutions located in more than 200 countries/regions, were identified. The papers were published under four dominating WoS categories, namely pharmacology/pharmacy (34.4%), plant sciences (28.6%), medicinal chemistry (25.3%), and integrative complementary medicine (20.6%). India (14.6%) and China (13.2%) were dominating the publication space. The United States and Brazil also had more than 8.0% contribution each. The rest of the top ten countries/regions were mainly from Asia. There were around ten-fold more original articles (84.6%) than reviews (8.4%). CONCLUSIONS Ethnopharmacological research has a consistent focus on food and plant sciences, (bio)chemistry, complementary medicine and pharmacology, with a more limited scientific acceptance in the socio-cultural sciences. Dynamic global contributions have been shifting from developed countries to economically and scientifically emerging countries in Asia, South America and the Middle East. Research on recording medicinal plant species used by traditional medicine continues, but the evaluation of specific properties or treatment effects of extracts and compounds has increased enormously. Moreover increasing attention is paid to some widely distributed natural products, such as curcumin, quercetin, and rutin.

Abstract
The pursuit for effective strategies inhibiting the amyloidogenic process in neurodegenerative disorders, such as Alzheimer’s disease (AD), remains one of the main unsolved issues, and only a few drugs have demonstrated to delay the degeneration of the cognitive system. Moreover, most therapies induce severe side effects and are not effective at all stages of the illness. The need to find novel and reliable drugs appears therefore of primary importance. In this context, natural compounds have shown interesting beneficial effects on the onset and progression of neurodegenerative diseases, exhibiting a great inhibitory activity on the formation of amyloid aggregates and proving to be effective in many preclinical and clinical studies. However, their inhibitory mechanism is still unclear. In this work, ensemble docking and molecular dynamics simulations on S-shaped Aβ42 fibrils have been carried out to evaluate the influence of several natural compounds on amyloid conformational behaviour. A deep understanding of the interaction mechanisms between natural compounds and Aβ aggregates may play a key role to pave the way for design, discovery and optimization strategies toward an efficient destabilization of toxic amyloid assemblies.

Abstract
Background: Pain and distress are two common complications of cesarean section. Among complementary therapies, Eremostachys was introduced as a pain mitigator. This study aimed at investigating the effect of Eremostachys laciniata on cesarean section pain and distress. Materials and methods: This randomized clinical trial was conducted on 86 women who gave childbirth by cesarean section. The control group received 50 mg rectal diclofenac suppository every 8 h for 3 days, and the intervention group received 35 mg E. laciniata total extract suppository every 8 h up to three doses. Pain was measured with the Visual Analogue Scale at 8, 16, and 24 h after cesarean section. The Symptom Distress Scale was completed at 8 and 24 h after cesarean section. The Redness, Edema, Ecchymosis, Discharge, Approximation scale was completed 5 days after cesarean section. Findings: Pain score at 8, 16, and 24 h after surgery (15 min after intervention) was not significantly different between the intervention and control groups. The distress score 24 h after cesarean section showed a significant difference in favor of the control group according to Friedman’s test. There was a significant difference between the two groups in wound healing score, which indicated better efficacy of rectal diclofenac suppository than E. laciniata suppository. We assessed nausea, vomiting, headache, massive hemorrhage, and any type of anaphylactic reaction. No side events were observed in two groups. Conclusion: Rectal E. laciniata suppository could be introduced as a low-complication, appropriate, and effective medication in controlling pain and distress after cesarean section; more studies should be conducted on this matter.

Abstract
OBJECTIVE To analyse the associations between chronic respiratory diseases and intakes of total flavonoids and their major subclasses (flavanones, anthocyanins, flavan-3-ols, flavonols, flavones, polymers and proanthocyanidins). DESIGN Multi-case-control study. SETTING The analysis was conducted in the frame of the Genes Environment Interaction in Respiratory Diseases (GEIRD) study. The European Prospective Investigation into Cancer and Nutrition FFQ was used to ascertain dietary intake. Multinomial regression models adjusting for age, sex, centre, BMI, smoking habit, alcohol intake, education, total energy intake, vitamin C intake and total fruit intake were used to examine the associations between dietary exposures and the relative risk ratio (RRR) of being a case. PARTICIPANTS Individuals (n 990) hierarchically defined as follows: cases with asthma (current, n 159; past, n 78), chronic bronchitis (n 47), rhinitis (allergic rhinitis, n 167; non-allergic rhinitis, n 142) and controls (n 97). RESULTS An increase of 1 sd in flavanones was associated with a reduced risk of non-allergic rhinitis (adjusted RRR = 0·68, 95 % CI 0·47, 0·97); a similar result was found comparing the highest v. lowest quartile of flavanones intake (adjusted RRR = 0·24, 95 % CI 0·10, 0·59). CONCLUSIONS Flavonoids contained in fruits and vegetables, especially flavanones, might reduce the risk of non-allergic rhinitis. No associations were found between other flavonoids and the considered outcomes.

Abstract
Alzheimer's Disease (AD) is a neurodegenerative disorder related with the increase of age and it is the main cause of dementia in the world. AD affects cognitive functions, such as memory, with an intensity that leads to several functional losses. The continuous increase of AD incidence demands for an urgent development of effective therapeutic strategies. Despite the extensive research on this disease, only a few drugs able to delay the progression of the disease are currently available. In the last years, several compounds with pharmacological activities isolated from plants, animals and microorganisms, revealed to have beneficial effects for the treatment of AD, targeting different pathological mechanisms. Thus, a wide range of natural compounds may play a relevant role in the prevention of AD and have proven to be efficient in different preclinical and clinical studies. This work aims to review the natural compounds that until this date were described as having significant benefits for this neurological disease, focusing on studies that present clinical trials.

Abstract
The long-term effects of a number of flavonoids (such as apigenin, luteolin and amentoflavone) and vinpocetine on the neutral endopeptidase (NEP) and angiotensin-converting enzyme (ACE) were investigated. It was shown that apigenin, luteolin and vinpocetin are able to induce the activity of both NEP and ACE associated with the inhibition of the proliferation of the neuroblastoma cell line SK-N-SH. Amentoflavone has no effect on either NEP or ACE activity. An additional enhancement of cellular NEP activity could be detected after the treatment of the cells with a combination of both arabinosylcytosine and either apigenin or luteolin. This effect supports the assumption that apigenin and luteolin influence directly the gene expression of NEP. Taking into account the significant role of NEP and ACE in the degradation of amyloid beta peptides, the induction of both enzymes by long-term treatment with apigenin, luteolin and vinpocetine may have a beneficial effect regarding the prevention of the formation of amyloid plaques and the effect of these substances may be discussed as neuroprotective.

Abstract
Flavonoids are tricyclic polyphenolic compounds naturally occurring in plants. Being nature’s antioxidants flavonoids have been shown to reduce the damages induced by oxidative stress in cells. Besides being an antioxidant, flavonols are demonstrated to have anti-infective properties, i.e., antiviral, antifungal, anti-angiogenic, anti-tumorigenic, and immunomodulatory bioproperties. Plants use them as one of their defense mechanisms against radiation-induced DNA damage and also for fungal infections. The use of flavonols for fabrication of new drugs has been underway with objectives to develop safer and effective therapeutic agents. This review covers 15 flavonols for their structure, biological properties, role in plant metabolisms, and current research focused on computational drug design using flavonols for searching drug leads.

Abstract
This review offers a systematic understanding about how polyphenols target multiple inflammatory components and lead to anti-inflammatory mechanisms. It provides a clear understanding of the molecular mechanisms of action of phenolic compounds. Polyphenols regulate immunity by interfering with immune cell regulation, proinflammatory cytokines' synthesis, and gene expression. They inactivate NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) and modulate mitogen-activated protein Kinase (MAPk) and arachidonic acids pathways. Polyphenolic compounds inhibit phosphatidylinositide 3-kinases/protein kinase B (PI3K/AkT), inhibitor of kappa kinase/c-Jun amino-terminal kinases (IKK/JNK), mammalian target of rapamycin complex 1 (mTORC1) which is a protein complex that controls protein synthesis, and JAK/STAT. They can suppress toll-like receptor (TLR) and pro-inflammatory genes' expression. Their antioxidant activity and ability to inhibit enzymes involved in the production of eicosanoids contribute as well to their anti-inflammation properties. They inhibit certain enzymes involved in reactive oxygen species ROS production like xanthine oxidase and NADPH oxidase (NOX) while they upregulate other endogenous antioxidant enzymes like superoxide dismutase (SOD), catalase, and glutathione (GSH) peroxidase (Px). Furthermore, they inhibit phospholipase A2 (PLA2), cyclooxygenase (COX) and lipoxygenase (LOX) leading to a reduction in the production of prostaglandins (PGs) and leukotrienes (LTs) and inflammation antagonism. The effects of these biologically active compounds on the immune system are associated with extended health benefits for different chronic inflammatory diseases. Studies of plant extracts and compounds show that polyphenols can play a beneficial role in the prevention and the progress of chronic diseases related to inflammation such as diabetes, obesity, neurodegeneration, cancers, and cardiovascular diseases, among other conditions.

Abstract
BACKGROUND we have evaluated the antihypertensive effect of several flavonoid extracts in a rat model of arterial hypertension caused by chronic administration (6 weeks) of the nitric oxide synthesis inhibitor, L-NAME. METHODS Sprague Dawley rats received L-NAME alone or L-NAME plus flavonoid-rich vegetal extracts (Lemon, Grapefruit + Bitter Orange, and Cocoa) or purified flavonoids (Apigenin and Diosmin) for 6 weeks. RESULTS L-NAME treatment resulted in a marked elevation of blood pressure, and treatment with Apigenin, Lemon Extract, and Grapefruit + Bitter Orange extracts significantly reduced the elevated blood pressure of these animals. Apigenin and some of these flavonoids also ameliorated nitric oxide-dependent and -independent aortic vasodilation and elevated nitrite urinary excretion. End-organ abnormalities such as cardiac infarcts, hyaline arteriopathy and fibrinoid necrosis in coronary arteries and aorta were improved by these treatments, reducing the end-organ vascular damage. CONCLUSIONS the flavonoids included in this study, specially apigenin, may be used as functional food ingredients with potential therapeutic benefit in arterial hypertension.

Abstract
BACKGROUND The Elaeagnus angustifolia fruit has been traditionally used in Iranian herbal medicine to treat diarrhea and rheumatoid arthritis. In the present study, the effects of E. angustifolia fruit extract on the acute and chronic phases of formalin-induced rat paw edema were examined. METHODS The acute and chronic anti-inflammatory effects of E. angustifolia fruit extract were investigated through the subcutaneous injection of 100 μL of formalin (2.5%) into a rat's hind paw. Thirty minutes before the procedure, the experimental groups were treated intraperitoneally with hydroalcoholic fruit extracts of E. angustifolia (concentrations of 100, 300, 700, and 1000 mg/kg); sodium salicylate (SS, 400 mg/kg) and distilled water were used as positive and negative control groups, respectively. Treatment with SS and the fruit extracts were performed daily for 8 days, and the degree of edema was measured by using mercury plethysmometer and digital caliper. RESULTS In the acute anti-inflammatory study, the extract showed a significant anti-inflammatory effect in a dose-dependent manner. The results of 1000 mg/kg of the extract was significantly different compared with the negative control group (p<0.05) and was comparable to sodium salicylate (p<0.05). Results from the chronic study suggested that E. angustifolia extract significantly reduced paw edema and inflammation in a dose-dependent manner. The results also showed that the measurement by digital caliper and mercury plethysmometer were both reliable and might be applied interchangeably (p<0.01). Phytochemical tests indicated that the hydroalcoholic fruit extract of E. angustifolia was positive for cardiac glycosides, flavonoids, terpenoids, and saponins. CONCLUSIONS Based on our findings, the E. angustifolia fruit extract probably has acute and chronic anti-inflammatory activities to support its applications in folk medicine.

Abstract
OBJECTIVE The aim of the present study was to evaluate anti-inflammatory activity of methanolic extract of Terminalia coriacea. MATERIALS AND METHODS A methanolic extract of T. coriacea leaves was studied in albino Wistar rats with carrageenan-induced paw edema, an acute model, and cotton pellet-induced granuloma, a chronic model, at 3 oral test doses (125, 250, and 500 mg/kg). Aspirin 100 mg/kg was used as a positive control. Paw volume and wet and dry weights of cotton pellets were determined. The data were analyzed by one-way ANOVA followed by Dunnett's multiple comparison test. RESULTS The test extract at doses of 125 and 250 mg/kg decreased paw volume and wet and dry weights of cotton pellets. The highest test dose (500 mg/kg) displayed a response comparable to that of the standard drug (p < 0.01) on paw volume. The extract produced similar (p < 0.05) decrease in wet weight of the cotton pellet at 125 and 250 mg/kg, whereas the effect of 500 mg/kg of the extract was comparable to that of aspirin 100 mg/kg (p < 0.01). The extract of T. coriacea at 500 mg/kg induced the most significant (p < 0.01) effect on wet weight of granulomatous tissue. CONCLUSION The methanolic extract of T. coriacea leaves successfully decreased paw edema as well as dry and wet weights of granulomatous tissue in both acute and chronic inflammatory models thus confirming the anti- edematogenic, antitransudative, and antiproliferative properties of T. coriacea.

Abstract
Croton cajucara Benth. is a medicinal plant popularly used in the Brazilian Amazonia, where it is known as sacaca, being consumed as tea, decoction or infusion of the leaves and stem bark. From a decoction of the leaves, a comprehensive phytochemical analysis was developed by liquid chromatography-mass spectrometry. Many compounds were identified for the first time in C. cajucara, such as O-glycosides of kaempferol and quercetin, flavonoid-C-glycosides, tannins and cinnamic acid derivatives. These compounds were fractionated by polarity and assayed for their anti-inflammatory activity, using a model of mice edema, induced by an intraplantar injection of carrageenan. All fractions exhibited anti-inflammatory properties.

Abstract
Aging leads to hypothalamic inflammation, but does so more slowly in mice whose lifespan has been extended by mutations that affect GH/IGF‐1 signals. Early‐life exposure to GH by injection, or to nutrient restriction in the first 3 weeks of life, also modulate both lifespan and the pace of hypothalamic inflammation. Three drugs extend lifespan of UM‐HET3 mice in a sex‐specific way: acarbose (ACA), 17‐α‐estradiol (17αE2), and nordihydroguaiaretic acid (NDGA), with more dramatic longevity increases in males in each case. In this study, we examined the effect of these anti‐aging drugs on neuro‐inflammation in hypothalamus and hippocampus. We found that age‐associated hypothalamic inflammation is reduced in males but not in females at 12 months of age by ACA and 17αE2 and at 22 months of age in NDGA‐treated mice. The three drugs blocked indices of hypothalamic reactive gliosis associated with aging, such as Iba‐1‐positive microglia and GFAP‐positive astrocytes, as well as age‐associated overproduction of TNF‐α. This effect was not observed in drug‐treated female mice or in the hippocampus of the drug‐treated animals. On the other hand, caloric restriction (CR; an intervention that extends the lifespan in both sexes) significantly reduced hypothalamic microglia and TNF‐α in both sexes at 12 months of age. Together, these results suggest that the extent of drug‐induced changes in hypothalamic inflammatory processes is sexually dimorphic in a pattern that parallels the effects of these agents on mouse longevity and that mimics the changes seen, in both sexes, of long‐lived nutrient restricted or mutant mice.

Abstract
Over the past two decades, extensive studies have revealed that inflammation represents a major risk factor for various human diseases. Chronic inflammatory responses predispose to pathological progression of chronic illnesses featured with penetration of inflammatory cells, dysregulation of cellular signaling, excessive generation of cytokines, and loss of barrier function. Hence, the suppression of inflammation has the potential to delay, prevent, and to treat chronic diseases. Flavonoids, which are widely distributed in humans daily diet, such as vegetables, fruits, tea and cocoa, among others, are considered as bioactive compounds with anti-inflammatory potential. Modification of flavonoids including hydroxylation, o-methylation, and glycosylation, can alter their metabolic features and affect mechanisms of inflammation. Structure-activity relationships among naturally occurred flavonoids hence provide us with a preliminary insight into their anti-inflammatory potential, not only attributing to the antioxidant capacity, but also to modulate inflammatory mediators. The present review summarizes current knowledge and underlies mechanisms of anti-inflammatory activities of dietary flavonoids and their influences involved in the development of various inflammatory-related chronic diseases. In addition, the established structure-activity relationships of phenolic compounds in this review may give an insight for the screening of new anti-inflammatory agents from dietary materials.

Abstract
BACKGROUND Gaillardia grandiflora Hort. ex Van Houte and Gaillardia pulchella Foug are flowering plants widely cultivated in Egypt for their ornamental value. Previous reports demonstrated that sesquiterpene derivatives represent the major compounds in both species. Moreover, only few flavones were identified from genus Gaillardia and few studies on the cytotoxicity of G. pulchella were found. AIM OF THE STUDY Investigation of the phenolic constituents of the aerial parts of both species and evaluation of their anti-inflammatory and hepatoprotective activities. MATERIALS AND METHODS The 80% aqueous methanol extracts (AME) were prepared for both plants and evaluated for their biological activities. Phytochemical investigation of both extracts resulted in isolation of twelve compounds, which have been identified on the basis of ultraviolet, 1D and 2D nuclear magnetic resonance spectroscopy and negative ESI-MS. RESULTS The new 8-hydroxyapigenin 6-O-β-D-apiofuranosyl-(1'''→6'')-C-β-D-4C1-glucopyranoside was isolated from G. grandiflora for the first time in nature, along with schaftoside, luteolin 6-C-β-D-4C1-glucopyranoside 8-methyl ether, apigenin 6-C-β-D-4C1-glucopyranoside 8-methyl ether, isoorientin, isovitexin, 6-methoxyluteolin and hispidulin, as well as vicenin-2, vitexin, luteolin and apigenin, which were isolated from G. pulchella together with 6-methoxyluteolin. Furthermore, the AME of both species were found to be nontoxic to mice and exhibited significant anti-inflammatory and hepatoprotective activities in dose dependent manner. CONCLUSION Current results shed light on the phenolic constituents of G. grandiflora and G. pulchella aerial parts and the safety of the AME of both species, in addition to their significant anti-inflammatory and hepatoprotective activities. Both plant species may be promising candidates for natural anti-inflammatory and hepatoprotective drugs. SUMMARY Phytochemical investigation of Gaillardia grandiflora and Gaillardia pulchella 80% aqueous methanol extracts of the aerial parts led to the isolation of twelve compoundsThe new compound 8-hydroxyapigenin 6-O-β-D-apiofuranosyl-(1''''→6'')-C-β-D-4C1-glucopyranoside was isolated from G. grandiflora for the first time in natureSchaftoside, luteolin 6-C-β-D-4C1-glucopyranoside 8-methyl ether, apigenin 6-C-β-D-4C1-glucopyranoside 8-methyl ether, isoorientin, isovitexin, 6-methoxyluteolin and hispidulin were isolated from G. grandifloraVicenin-2, vitexin, luteolin, apigenin and 6-methoxyluteolin were isolated from G. pulchellaThe extracts of both species were nontoxic to mice up to 5 g/kg body weightBoth extracts exhibited significant anti-inflammatory and hepatoprotective activities in dose dependent manner Abbreviations used: ALP: Alkaline phosphatase; ALT: Alanine aminotransferase; AME: The 80% aqueous methanol extract of G. grandiflora or G. pulchella aerial parts; AST: Aspartate aminotransferase; br d: Broad doublet; Comp-PC: Comparative paper chromatography; d: Doublet; 2D-PC: Two-dimensional paper chromatography; DMSO-d6: Deuterated dimethyl sulfoxide; G.: Gaillardia; GPx: Glutathione peroxidase; GRd: Glutathione reductase; GSH: glutathione; GST: Glutathione-S-transferase; J: Nuclear spin-spin coupling constant; m: Multiplet; [M-H]-: Molecular ion peak; MDA: Malondialdehyde; m/z: Mass/charge ratio; NO: Nitric oxide; p: Probability; PC: Paper chromatography; Rf: Retention flow; rpm: Rotation per minute; s: Singlet; SDE: The ethanol extract of Scoparia dulcis; SE: Standard error; SOD: Superoxide dismutase; TMS: Tetramethylsilane; λmax: Maximum fluorescence emission wavelength.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jatropha neopauciflora Pax is an endemic species to Mexico, and its latex is used in traditional medicine to treat mouth infections when there are loose teeth and to heal wounds. In this research, we evaluated the antimicrobial activity, wound healing efficacy and chemical characterization of J. neopauciflora latex in a murine model. MATERIALS AND METHODS The antibacterial activity was determined using Gram positive and negative strains, the antifungal activity was determined using yeast and filamentous fungi, and the wound healing efficacy of the latex was determined using the tensiometric method. The anti-inflammatory activity was evaluated using the plantar oedema model in rats, administering the latex orally and topically. Cytotoxic activity was determined in vitro in two different cell lines. Antioxidant capacity, total phenolics, total flavonoids, reducing carbohydrates and latex proteins were quantified. The latex analysis was performed by High Performance Liquid Chromatography (HPLC). Finally, molecular exclusion chromatography was performed. RESULTS The latex demonstrated antibacterial activity. The most sensitive strains were Gram positive bacteria, particularly S. aureus (MIC=2mg/mL), and the latex had bacteriostatic activity. The latex did not show antifungal activity. The latex demonstrated a wound-healing efficacy, even the positive control (Recoveron). The orally administered latex demonstrated the best anti-inflammatory activity and was not toxic to either of the 2 cell lines. The latex had a high antioxidant capacity (SA50=5.4µg/mL), directly related to the total phenolic (6.9mg GAE/mL) and flavonoid (12.53µg QE/mL) concentration. The carbohydrate concentration was 18.52µg/mL, and fructose was the most abundantly expressed carbohydrate in the latex (14.63µg/mL, 79.03%). Additionally, the latex contained proteins (7.62µg/mL) in its chemical constitution. As secondary metabolites, the HPLC analysis indicated the presence of phenols and flavonoids. CONCLUSIONS The J. neopauciflora latex promotes the wound healing process by avoiding microorganism infections, inhibiting inflammation and acting as an antioxidant.

Abstract
This study is designed to evaluate the analgesic and anti-inflammatory activities of aqueous extract (AE) of Cistus ladanifer L. leaves in experimental animal models. The central analgesic activity of C. ladanifer AE is studied using hot plate method in rats, and the acute anti-Inflammatory activity of C. ladanifer is investigated by rats paw edema induced by subplantar injection of 0.5% carrageenan into the right hind paw. Rats are pretreated with AE of C. ladanifer at different doses (150, 175, and 200 mg/kg, i.p.). The tramadol and indomethacin are used as reference drugs for analgesic and anti-inflammatory studies, respectively. Our results show that the AE of C. ladanifer exhibited anti-inflammatory and analgesic effects dose dependent. In anti-inflammatory activity, the AE of C. ladanifer at all doses reduced significantly the edema paw inflammation after carrageenan injection. Furthermore at 200 mg/kg, the effect of AE is highly important than that of other doses. In addition, the same AE demonstrates significant analgesic effect in thermal-induced pain model. So, this activity is proved by significant reduction of pain score after administration of AE at all doses. The nociception protection effects in this case are, respectively, 70.3%, 74.55%, and 93.33% after administration of AE of C. ladanifer at doses 150, 175, and 200 mg/kg b.w. The results of our findings suggest that AE of C. ladanifer has potential analgesic and anti-inflammatory activities with evidence of possible involvement of peripheral and central effects in its actions.
