Antinociceptive in vivo activity and chemical profiling by UHPLC-MS/MS of stem bark and leaves extracts of Ficus maxima Mill. (Moraceae). JOURNAL OF ETHNOPHARMACOLOGY 2024; 337:118793. [PMID: 39251148 DOI: 10.1016/j.jep.2024.118793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 09/01/2024] [Accepted: 09/04/2024] [Indexed: 09/11/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ficus maxima is a medicinal plant extensively used in traditional medicine by Indigenous peoples across Central and South America. It is a member of the family Moraceae, subgenus Pharmacosycea, employed in treating various conditions, including intestinal parasites, gingivitis, internal inflammations, and snake bites. Despite its significant pharmacological potential, the species remains underrepresented in scientific literature. AIM OF THE STUDY This study aimed to evaluate the in vivo antinociceptive properties of leaf (ELFM) and stem bark (EBFM) extracts from Ficus maxima. Additionally, the chemical composition of these extracts was determined using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). MATERIALS AND METHODS Plant material was collected in Abaetetuba, Pará, Brazil, in October 2013 and subjected to static maceration to obtain crude ELFM and EBFM. Bio-guided fractionation was performed by sequential liquid-liquid partitioning with hexane (Hex), dichloromethane (DCM), and ethyl acetate (EtOAc), yielding the following fractions: ELFM-Hex and EBFM-Hex, ELFM-DCM and EBFM-DCM, and ELFM-EtOAc and EBFM-EtOAc. The biological activity of EBFM, ELFM, and their respective fractions were evaluated using the formalin-induced pain test and the hot plate test, followed by an assessment of their mechanisms of action. The UHPLC-MS/MS analysis was conducted using electrospray ionization (ESI) in both positive and negative modes. Metabolite annotation was facilitated by MS/MS libraries and molecular networks constructed on the GNPS platform. RESULTS The reactivity time to formalin in the neurogenic phase was reduced from 84.7 ± 7.6 s (100%) to 37.3 ± 4.7 s (44%), 33.1 ± 6.3 s (39%), 40.7 ± 7.4 s (48%), 57.2 ± 2.6 s (77%), 49.7 ± 4.1 s (58%), 46.8 ± 8.1 s (55%), and 52.4 ± 5.3 s (61%) after treatment with ASA, morphine, EBFM, ELFM, ELFM-Hex, ELFM-DCM, and ELFM-EtOAc at doses of 30 mg/kg, respectively. In the inflammatory phase, the reactivity time to formalin was reduced from 124.3 ± 25.9 s (100%) to 49.7 ± 4.7 s (40%), 9.8 ± 4.3 s (8%), 32.5 ± 8.5 s (26%), 59.8 ± 16.8 s (48%), and 54.4 ± 7.3 s (44%) after treatment with ASA, morphine, EBFM, ELFM, and ELFM-Hex at doses of 30 mg/kg, respectively. A reversal of the antinociceptive action of EBFM and ELFM was observed in the inflammatory phase after treatment with atropine, a muscarinic antagonist, and naloxone, an opioid antagonist, respectively. In the hot plate test, EBFM showed Antinociceptive Activity (AA) of 62.6 ± 9.2% after 90 min; however, there was a reversal of AA to 8.6 ± 2.8% when naloxone was used. The UHPLC-MS/MS metabolite analysis revealed the presence of loliolide (3), luteolin (13), lupeol (14), gallic acid (15), chlorogenic acid (16), pygenic acid A (17), and other metabolites from the alkaloids and fatty acids classes.

Ageratum conyzoides Extract Ameliorates Testosterone-Induced Benign Prostatic Hyperplasia via Inhibiting Proliferation, Inflammation of Prostates, and Induction of Apoptosis in Rats. Nutrients 2024; 16:2267. [PMID: 39064710 PMCID: PMC11280401 DOI: 10.3390/nu16142267] [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: 06/27/2024] [Revised: 07/12/2024] [Accepted: 07/12/2024] [Indexed: 07/28/2024] Open
Abstract
Ageratum conyzoides, an annual herbaceous plant that inhabits tropical and subtropical regions, has been traditionally used in Asia, Africa, and South America for phytotherapy to treat infectious and inflammatory conditions. However, the pharmacological effects of standardized ethanolic extract of Ageratum conyzoides (ACE) on benign prostatic hyperplasia (BPH) remain unexplored. The objective of this research is to examine the potential physiological impacts of ACE, a traditionally utilized remedy for inflammatory ailments, in a rat model with BPH induced by testosterone propionate (TP). Rats were subcutaneously administered TP (3 mg/kg) to induce BPH and concurrently orally administered ACE (20, 50, and 100 mg/kg) daily for 42 days. ACE markedly improved BPH characteristics, including prostate weight, prostate index, and epithelial thickness, while also suppressing androgens and related hormones. The findings were supported by a decrease in androgen receptor and downstream signals associated with BPH in the prostate tissues of the ACE groups. Furthermore, increased apoptotic signals were observed in the prostate tissue of the ACE groups, along with heightened detection of the apoptotic nucleus compared to the BPH alone group. These changes seen in the group that received finasteride were similar to those observed in this group. These findings suggest that ACE shows promise as an alternative phytotherapeutic agent for treating BPH.

Abstract
Polymethoxylated flavonoids (PMFs) are a subclass of flavonoids found in citrus fruits that have shown multifunctional biological activities and potential anticancer effects against breast cancer. We studied the absorption, metabolism, species source, toxicity, anti-cancer mechanisms, and molecular targets of PMFs to better utilize their anticancer activity against breast cancer. We discuss the absorption and metabolism of PMFs in the body, including the methylation, demethylation, and hydroxylation processes. The anticancer mechanisms of PMFs against breast cancer were also reviewed, including the estrogen activity, cytochrome P-450 enzyme system, and arylhydrocarbon receptor (AhR) inhibition, along with various molecular targets and potential anticancer effects. Although PMFs may be advantageous in the prevention and treatment for breast cancer, there is a lack of clinical evidence and data to support their efficacy. Despite their promise, there is still a long way to go before PMFs can be applied clinically.

Abstract
Pain continues to be an enormous global health challenge, with millions of new untreated or inadequately treated patients reported annually. With respect to current clinical applications, opioids remain the mainstay for the treatment of pain, although they are often associated with serious side effects. To optimize their tolerability profiles, medicinal chemistry continues to study novel ligands and innovative approaches. Among them, natural products are known to be a rich source of lead compounds for drug discovery, and they hold potential for pain management. Traditional medicine has had a long history in clinical practice due to the fact that nature provides a rich source of active principles. For instance, opium had been used for pain management until the 19th century when its individual components, such as morphine, were purified and identified. In this review article, we conducted a literature survey aimed at identifying natural products interacting either directly with opioid receptors or indirectly through other mechanisms controlling opioid receptor signaling, whose structures could be interesting from a drug design perspective.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ageratum conyzoides L. (Asteraceae), a well-known and widely distributed traditional tropical medicinal herb, has been used to treat diverse diseases. Our preliminary research has shown that aqueous extracts of A. conyzoides leaf (EAC) have anti-inflammatory activity. However, the detailed underlying anti-inflammatory mechanism of EAC is still unclear. AIM OF THE STUDY To determine the anti-inflammatory mechanism of action of EAC. MATERIALS AND METHODS The major constituents of EAC were identified by ultra-performance liquid chromatography (UPLC) combined with quadrupole-time-of-flight mass/mass spectrometry (UPLC-Q-TOF-MS/MS). LPS and ATP were used to activate the NLRP3 inflammasome in two types of macrophages (RAW 264.7 and THP-1 cells). The cytotoxicity of EAC was measured by the CCK8 assay. The levels of inflammatory cytokines and NLRP3 inflammasome-related proteins were detected by ELISA and western blotting (WB), respectively. The oligomerization of NLRP3 and ASC and the resulting inflammasome complex formation were observed by immunofluorescence. The intracellular reactive oxygen species (ROS) level was measured by flow cytometry. Finally, an MSU-induced peritonitis model was established to evaluate the anti-inflammatory effects of EAC in vivo. RESULTS Twenty constituents were identified in the EAC. Kaempferol 3,7-diglucoside, 1,3,5-tricaffeoylquinic acid, and kaempferol 3,7,4'-triglucoside were found to be the most potent ingredients. EAC significantly reduced the levels of IL-1β, IL-18, TNF-α, and caspase-1 in the two types of activated macrophages, implying that EAC can inhibit the activation of the NLRP3 inflammasome. A mechanistic study revealed that EAC inhibited NLRP3 inflammasome activation by blocking NF-κB signalling pathway activation and scavenging the level of intracellular ROS to prevent NLRP3 inflammasome assembly in macrophages. Furthermore, EAC attenuated the in vivo expression of inflammatory cytokines by suppressing NLRP3 inflammasome activation in a peritonitis mouse model. CONCLUSION Our results demonstrated that EAC inhibited inflammation by suppressing NLRP3 inflammasome activation, highlighting that this traditional herbal medicine might be used to treat NLRP3 inflammasome-driven inflammatory diseases.

Abstract
The NLRP3 inflammasome, which plays a central role in innate immunity, is linked to a variety of inflammatory diseases, and thus it may provide a new target for the treatment of those diseases. Biosynthesized silver nanoparticles (AgNPs), particularly those synthesized using medicinal plant extracts, have recently been shown to be a promising therapeutic option. Herein, the aqueous extract of Ageratum conyzoids was used to prepare a series of sized AgNPs (AC-AgNPs), in which the smallest mean particle size was 30 ± 1.3 nm with a polydispersity of 0.328 ± 0.009. The ζ potential value was -28.77 with a mobility of -1.95 ± 0.24 cm2/(v·s). Its main ingredient, elemental silver, accounted for about 32.71 ± 4.87% of its mass, and other ingredients included amentoflavone-7,7⁗-dimethyl ether, 1,3,5-tricaffeoylquinic acid, kaempferol 3,7,4'-triglucoside, 5,6,7,3',4',5'-hexamethoxyflavone, kaempferol, and ageconyflavone B. In LPS+ATP-stimulated RAW 264.7 and THP-1 cells, AC-AgNPs significantly inhibited the release of IL-1β, IL-18, TNF-α, and caspase-1, indicating that AC-AgNPs can inhibit the activation of the NLRP3 inflammasome. The mechanistic study revealed that AC-AgNPs could decrease the phosphorylation levels of IκB-α and p65, resulting in decreased expression of NLRP3 inflammasome-related proteins, including pro-IL-1β, IL-1β, procaspase 1, caspase 1P20, NLRP3, and ASC, and also scavenge the level of intracellular ROS to prevent NLRP3 inflammasome assembly. Furthermore, AC-AgNPs attenuated the in vivo expression of inflammatory cytokines by suppressing NLRP3 inflammasome activation in a peritonitis mouse model. Our study provides evidence that the as-prepared AC-AgNPs can inhibit the inflammatory process by suppressing NLRP3 inflammasome activation and might be used to treat NLRP3 inflammasome-driven inflammatory diseases.

Abstract
Neuropathic pain is chronic pain resulting from central or peripheral nerve damage that remains difficult to treat. Current evidence suggests that nobiletin, isolated from Citrus reticulata Blanco, possesses analgesic and neuroprotective effects. However, its effect on neuropathic pain has not been reported. This study evaluated the analgesic effect of nobiletin on neuropathic pain induced by chronic constriction injury (CCI) in mice. In vivo, mice were intragastrically administered with nobiletin (30, 60, 120 mg/kg) for eight consecutive days, respectively. Our study indicated that nobiletin ameliorated mechanical allodynia, cold allodynia and thermal hyperalgesia on CCI mice at doses that do not induce significant sedation. Moreover, nobiletin could ameliorate axonal and myelin injury of the sciatic nerve and further restore abnormal sciatic nerve electrical activity on CCI mice. In vitro studies indicated that nobiletin could suppress the proteins and mRNA expression of the IRF5/P2X4R/BDNF signalling pathway in fibronectin-induced BV2 cells. Overall, our results indicated that nobiletin might exert an analgesic effect on CCI-induced neuropathic pain in mice by inhibiting the IRF5/P2X4R/BDNF signalling pathway in spinal microglia. This study provided a novel potential therapeutic drug for neuropathic pain and new insights into the pharmacological action of nobiletin.

Preclinical Pharmacokinetic and Pharmacodynamic Investigation of 5'-Methoxynobiletin from Ageratum conyzoides: In vivo and In silico Approaches. Pharm Res 2022; 39:2135-2145. [PMID: 35831672 DOI: 10.1007/s11095-022-03332-9] [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: 09/13/2021] [Accepted: 07/04/2022] [Indexed: 11/26/2022]
Abstract
PURPOSE 5'-methoxynobiletin (5'-MeONB), a polymethoxyflavone isolated from A. conyzoides, has shown anti-inflammatory property. Nevertheless, the antinociceptive activity and pre-clinical pharmacokinetics (PK) characteristics of 5'-MeONB remain unknown. Considering the anti-inflammatory potential of the 5'-MeONB, this study aimed to investigate the pre-clinical PK behavior of 5'-MeONB, as well as its time course antinociceptive activity. METHODS 5'-MeONB plasma concentrations were determined in Wistar rats after intravenous (i.v.) (10 mg/kg) and oral (50 mg/kg) administration, and in Swiss mice after oral administration (100 mg/kg). Plasma samples were deproteinization and 5'-MeONB quantified by a validated UPLC-MS method. Additionally, the antinociceptive activity of 5'-MeONB was evaluated after 15, 30, 60, 180 and 360 min following oral administration on the acute nocifensive behavior of mice induced by formalin. RESULTS 5'-MeONB rats and mice plasma concentration-time profiles were best one-compartment model. After i.v. administration to rats, a short half-life, a high clearance and moderate volume of distribution at steady state were observed. Similar results were obtained after oral administration. The oral bioavailability ranged from 8 to 11%. Additionally, 5'-MeONB exhibited antinociceptive activity in both formalin phases, especially in the inflammatory phase of the model, inhibiting 68% and 91% of neurogenic and inflammatory responses, respectively, after 30 min of oral administration. CONCLUSIONS The results described here provide novel insights on 5'-MeONB pharmacokinetics and pharmacodynamic effect, serving as support for future studies to confirm this compound as anti-nociceptive and anti-inflammatory effective agent.

Abstract
Australian tropical plants have been a rich source of food (bush food) and medicine to the first Australians (Aboriginal people), who are believed to have lived for more than 50,000 years. Plants such as spreading sneezeweed (Centipeda minima), goat’s foot (Ipomoea pes-caprae), and hop bush (Dodonaea viscosa and D. polyandra) are a few popular Aboriginal medicinal plants. Thus far, more than 900 medicinal plants have been recorded in the tropical region alone, and many of them are associated with diverse ethnomedicinal uses that belong to the traditional owners of Aboriginal people. In our effort to find anti-inflammatory lead compounds in collaboration with Aboriginal communities from their medicinal plants, we reviewed 78 medicinal plants used against various inflammation and inflammatory-related conditions by Aboriginal people. Out of those 78 species, we have included only 45 species whose crude extracts or isolated pure compounds showed anti-inflammatory properties. Upon investigating compounds isolated from 40 species (for five species, only crude extracts were studied), 83 compounds were associated with various anti-inflammatory properties. Alphitolic acid, Betulinic acid, Malabaric acid, and Hispidulin reduced proinflammatory cytokines and cyclooxygenase enzymes (COX-1 and 2) with IC50 values ranging from 11.5 to 46.9 uM. Other promising anti-inflammatory compounds are Brevilin A (from Centipeda minima), Eupalestin, and 5′-methoxy nobiletin (from Ageratum conyzoides), Calophyllolide (from Calophyllum inophyllum), and Brusatol (from Brucea javanica). D. polyandra is one example of an Aboriginal medicinal plant from which a novel anti-inflammatory benzoyl ester clerodane diterpenoid compound was obtained (compound name not disclosed), and it is in the development of topical medicines for inflammatory skin diseases. Medicinal plants in the tropics and those associated with indigenous knowledge of Aboriginal people could be a potential alternative source of novel anti-inflammatory therapeutics.

Abstract
Inflammatory diseases are considered major threats to human health worldwide. In Bangladesh, a number of medicinal plants have been used in traditional medicine from time immemorial in the treatment of diverse diseases, including inflammatory disorders. This assignment aims at providing the status of the medicinal plants of Bangladesh which are traditionally used in the management of inflammatory disorders and are investigated for their anti-inflammatory prospects using different preclinical studies and future research directions. The information of medicinal plants assembled in this review was obtained from a literature search of electronic databases such as Google Scholar, PubMed, Scopus, Web of Science and ScienceDirect up to December, 2020 from publications on plants investigated for their anti-inflammatory activities, in which the place of plant sample collection was identified as Bangladesh. Keywords for primary searches were “anti-inflammatory,” “Bangladeshi,” and “medicinal plants.” Criteria followed to include plant species were plants that showed significant anti-inflammatory activities in 1) two or more sets of experiments in a single report, 2) same or different sets of experiments in two or more reports, and, 3) plants which are traditionally used in the treatment of inflammation and inflammatory disorders. In this study, 48 species of medicinal plants have been reviewed which have been used in traditional healing practices to manage inflammatory disorders in Bangladesh. The mechanistic pathways of the in vivo and in vitro study models used for the evaluation of anti-inflammatory properties of plant samples have been discussed. Selected plants were described in further detail for their habitat, anti-inflammatory studies conducted in countries other than Bangladesh, and anti-inflammatory active constituents isolated from these plants if any. Medicinal plants of Bangladesh have immense significance for anti-inflammatory activity and have potential to contribute toward the discovery and development of novel therapeutic approaches to combat diseases associated with inflammation. However, the plants reviewed in this article had chiefly undergone preliminary screening and require substantial investigations including identification of active molecules, understanding the mechanism of action, and evaluation for safety and efficacy to be followed by the formulation of safe and effective drug products.

Abstract
INTRODUCTION The ethnobotanical survey of the South-western Satpuda ranges has continued for decades. However, very few disease-specific surveys and their pharmacological validation have been published. The present study aimed to identify, document, and pharmacologically validate the tribal knowledge on anti-inflammatory medicinal plants. METHODS The field survey was conducted over a year from July 2015 to June 2016, scattered in the South-Western region of Satpuda Ranges. Documentation and identification of the medicinal herbs used often in the treatment of inflammatory conditions. Two plants, namely Eulophia herbacea Lindl., and Grewia flavescens A. Juss. were commonly used for inflammatory conditions. Phytopharmacological validation was done using carrageenan induced inflammation and CFA-induced arthritis. RESULTS The current investigation identified 32 plants from 22 different families as anti-inflammatory plants. G. flavescens exhibited substantial antiarthritic action in complete Freund's adjuvant-induced arthritis in rats, and E. herbacea showed powerful anti-inflammatory activity in carrageenan-induced rat paw edema model. This activity might be attributed to the presence of gallic acid, quercetin, β-sitosterol and lupeol. CONCLUSION The research reveals that selected plants had anti-inflammatory properties in both acute and chronic inflammation. Further studies to highlight the exact mechanism of action of these plants are warranted.

Traditional knowledge of medicinal plants on Gau Island, Fiji: differences between sixteen villages with unique characteristics of cultural value. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2021; 17:58. [PMID: 34635130 PMCID: PMC8507187 DOI: 10.1186/s13002-021-00481-w] [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: 02/28/2021] [Accepted: 09/13/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Traditional resource management (TRM) systems develop depending on local conditions, such as climate, culture, and environment. Most studies have focused on the TRM system itself, excluding the people who manage the system, and the relationship between the system and the people. The use of resources and people is intimately linked through the practice of TRM systems on Gau Island and this relationship needs to be understood to advance sustainable resource use. METHODS A survey was conducted on the use of medicinal plants on Gau Island, Fiji. Interviews were conducted from September 2013 to January 2015 with knowledgeable members of each community. The types of plants, prescriptions, and health problems were documented, and social and ecological factors affecting the sustainability of TRM of medicinal plants used in each of the 16 villages were statistically analysed by linear regression analysis. RESULTS A total of 58 medicinal plants used on a daily basis to treat 27 health problems were identified on Gau. Two medicinal plants, Botebotekoro (Ageratum conyzoides) and Totodro (Centella asiatica), were used in all districts to treat various health problems. There were contrasts between the villages in the medical lore and prescriptions, and villages often used different traditional treatments than others for the same ailment; therefore, the status and knowledge of medicinal plants have developed distinctly in each village. Geographical and social factors have been suggested as possible reasons for the differences in regional resource utilisation among villages. Statistical analysis of the relationship between the state of TRM and social and ecological factors suggest that community solidarity has a positive impact on the sustainable practice of TRM. This study showed that traditional practices simultaneously contribute to the conservation of the natural environment and the binding of communities. CONCLUSIONS The results highlight the importance of understanding how TRM systems can contribute to the conservation of the natural environment. Cultural activities are essential to raise community solidarity, which has led to the sustainable use of natural resources. This suggests that merely documenting the use of medicinal plants is not enough to ensure that the skills and knowledge are passed down to the next generation.

Abstract
The flavonoids in Ageratum conyzoides L. have been used in traditional medicine due to its anti-inflammatory and antibacterial properties. However, the specific mechanism of its antibacterial effect, and the potential therapeutic effect on vaginitis have not been well explained. The growth curves of E. coli, S. aurues, and P. aeruginosa after treatment with flavonoids were measured. The influences of flavonoids on the conductivity of bacterial culture medium and exudation of bacterial nucleic acid were also detected. Transcriptomics analysis was applied to analyze the potential mechanism of flavonoids. Flavonoids significantly suppressed the growth curves of E. coli, S. aurues, and P. aeruginosa, and increased the conductivity of bacteria and nucleic acid exudation. Transcriptomics analysis indicated that flavonoids could suppress bacteria by affecting the transcription and metabolism pathways. The obvious therapeutic effect of flavonoids on bacterial vaginitis was also observed. This study systematically analyzed the bacteriostatic mechanism of flavonoids, which should be helpful to develop new drugs based on the bacteriostatic effect of flavonoids.

Abstract
In this work, the bioaccessibility of polymethoxyflavones (PMFs) loaded in high internal phase emulsions (HIPE, ϕoil = 0.82) stabilized by whey protein isolate (WPI)-low methoxy pectin (LMP) complexes was evaluated using in vitro lipolysis and dynamic in vitro intestinal digestion studies. PMFs loaded HIPE was prepared by using aqueous dispersion of pre-formed biopolymeric complexes (WPI-LMP, 2:1 ratio) as the external phase and medium chain triglycerides oil (containing PMFs extracted from citrus peel) as the dispersed phase. The in vitro lipolysis study revealed that PMFs in HIPE became bioaccessible much higher than PMFs in medium chain triacylglycerols oil (MCT oil). In addition, by simulating the entire human gastrointestinal (GI) tract, the GI model TIM-1 demonstrated a 5- and 2-fold increase in the total bioaccessibility for two major PMFs encapsulated in HIPE, i.e. tangeretin (TAN) and nobiletin (NOB), respectively, as opposed to PMFs in MCT oil. Together these results from the digestion study showed that the incorporation of a high amount of PMFs into the viscoelastic matrix of HIPE could represent an innovative and effective way to design an oral delivery system. Such a system could be used to control and to improve the delivery of lipophilic bioactive compounds within the different compartments of the digestive tract, especially the human upper GI tract.

Marcetia taxifolia is a neotropical plant present in South America and it has been evaluated in several biological models due to the presence of active metabolites. Nevertheless, there is a limited quantity of studies related to the antiviral activity of the compounds present in this genus. In our work, the antiviral effect of the compounds isolated from the aerial parts of Marcetia taxifolia was evaluated against Hepatitis B virus (HBV), Herpes Simplex Virus type 1 (HSV-1), and Poliovirus type 1 (PV-1). The cytopathic effect and viral quantification by qPCR were determined as indicative of antiviral activity. Our data show that myricetin rhamnoside (MyrG), myricetin-3-α-O-ramnosil (1→6)-α-galactoside (MyrGG), 5,3'-dihydroxy-3,6,7,8,4'-pentamethoxyflavone (PMF), 5-hydroxy-3,6,7,3',4'pentamethoxyflavone (PMF-OH) had antiviral activity without cytotoxic effects. The methoxyflavones PMF and PMF-OH were the most active compounds, showing an antiviral effect against all the evaluated viruses. Computational studies showed that these compounds could interact with the Reverse Transcriptase. Altogether, these results suggest that the flavonoids (related to myricetin and methoxyflavones) are the main antiviral compounds present in the aerial parts of Marcetia taxifolia. Furthermore, our results showed that the methoxyflavones have a broad antiviral activity, which represents an opportunity to evaluate these flavonoids as lead molecules to develop new antiviral compounds.

Abstract
Polymethoxylavones (PMFs) are known to exhibit significant anti-inflammatory and neuroprotective properties. Nicotiana plumbaginifolia, an annual Bangladeshi herb, is rich in polymethoxyflavones that possess significant analgesic and anxiolytic activities. The present study aimed to determine the antinociceptive and neuropharmacological activities of polyoxygenated flavonoids namely- 3,3′,5,6,7,8-hexamethoxy-4′,5′-methylenedioxyflavone (1), 3,3′,4′,5′,5,6,7,8-octamethoxyflavone (exoticin) (2), 6,7,4′,5′-dimethylenedioxy-3,5,3′-trimethoxyflavone (3), and 3,3′,4′,5,5′,8-hexamethoxy-6,7-methylenedioxyflavone (4), isolated and identified from N. plumbaginifolia. Antinociceptive activity was assessed using the acetic-acid induced writhing, hot plate, tail immersion, formalin and carrageenan-induced paw edema tests, whereas neuropharmacological effects were evaluated in the hole cross, open field and elevated plus maze test. Oral treatment of compounds 1, 3, and 4 (12.5–25 mg/kg b.w.) exhibited dose-dependent and significant (p < 0.01) antinociceptive activity in the acetic-acid, formalin, carrageenan, and thermal (hot plate)-induced pain models. The association of ATP-sensitive K+ channel and opioid systems in their antinociceptive effect was obvious from the antagonist effect of glibenclamide and naloxone, respectively. These findings suggested central and peripheral antinociceptive activities of the compounds. Compound 1, 3, and 4 (12.5 mg/kg b.w.) demonstrated significant (p < 0.05) anxiolytic-like activity in the elevated plus-maze test, while the involvement of GABAA receptor in the action of compound 3 and 4 was evident from the reversal effects of flumazenil. In addition, compounds 1 and 4 (12.5–25 mg/kg b.w) exhibited anxiolytic activity without altering the locomotor responses. The present study suggested that the polymethoxyflavones (1–4) from N. Plumbaginifolia could be considered as suitable candidates for the development of analgesic and anxiolytic agents.

Abstract
A double-blind, randomized, placebo-controlled clinical trial assessed the efficacy and safety of Ageratum conyzoides in treating benign prostatic hypertrophy (BPH). In this study, 109 men with medically diagnosed BPH, aged 41-76 years, were administered the investigational product, A. conyzoides extract at a dose of 250 mg/d or placebo, q.d. for 12 weeks. The primary outcome measures were the International Prostate Symptom Score (IPSS), daily urinary frequency and safety evaluations. The secondary outcome measures were testosterone, dihydrotestosterone, oestradiol, sex hormone binding globulin (SHBG), Dehydroepiandrosterone sulfate (DHEA-S) and cortisol levels, and prostate specific antigen (PSA), lipids, blood glucose, the Aging Male's Symptom (AMS) Score and sexual function assessed by Derogatis Interview for Sexual Functioning-Self Report (DISF-SR). The effect of A. conyzoides L extract on gene expression of 5-alpha-reductase in human prostate cells was also investigated to elucidate a potential mechanism of action. The clinical study, showed a significant reduction in total IPSS score (p < 0.01) and day- and night-time urinary frequency (P < 0.01) over time after treatment with A. conyzoides. Steroid hormones, SHBG, PSA levels, lipids, and blood glucose remained within healthy reference range in both groups. There were no changes in AMS or DISF-SR in either group. Gene arrays demonstrated that A. conyzoides extract was effective in reducing the expression of mRNA coding for 5-alpha-reductase types 2 and 1 in human prostate epithelial cells. The overall results indicate that A. conyzoides may be an effective treatment for reducing symptoms of BPH in healthy men, in part, through inhibition of 5-alpha-reductase enzyme activity. © 2017 BioFactors, 43(6):789-800, 2017.

Abstract
Natural components continue to be an important source for the discovery and development of novel anticancer agents. Polymethoxyflavones are a class of flavonoids found in citrus fruits and medicinal plants used in traditional medicine. In the present study, the anticancer activity of the well-known nobiletin (5,6,7,8,3′,4′-hexamethoxyflavone) was compared against its less studied structural isomer 5,6,7,3′,4′,5′-hexamethoxyflavone. These compounds were evaluated on the Hs578T triple-negative breast cancer cell line and its more migratory subclone Hs578Ts(i)8. 5,6,7,3′,4′,5′-hexamethoxyflavone was found to be less toxic than nobiletin, while a similar growth inhibitory effect was observed after 72 h. Additionally, 5,6,7,3′,4′,5′-hexamethoxyflavone arrested the cell cycle in the G2/M phase, while no effect was observed on apoptosis or the migratory behavior of these cells. Furthermore, mechanistic studies revealed that the growth inhibition was concomitant with reduced phosphorylation levels of signaling molecules in the MAPK and Akt pathways as well as cell cycle regulators, involved in regulating cell proliferation, survival and cell cycle. In summary, the present study is the first to report on the anticancer activities of 5,6,7,3′,4′,5′-hexamethoxyflavone and to provide evidence that this flavone could have a greater potential than nobiletin for prevention or treatment of triple-negative breast cancer.

Abstract
Pterodon genus fruits are commercially available at the Brazilian medicinal market used in folk medicine due to their anti-inflammatory, analgesic, and anti-rheumatic effects. Previous studies demonstrated that furanditerpenes possessing vouacapan skeleton, isolated from Pterodon genus, possess expressive antinociceptive activities, with promising moiety for the development of new analgesic products. The antinociceptive properties of compounds 6α,7β-6α-hidroxivouacapan-7β-17β-lactone (HVL) and 6α-oxovouacapan-7β-17β-lactone (OVL), semi-synthetic analogues of furanditerpenes previously reported as analgesic agents were evaluated on animal experimental models (Spindola et al., 2010, 2011). The chemical-induced pain methods used in the present work, demonstrated for the first time that both compounds HVL and OVL have potential as important templates for the development of chronic pain control drugs. The main findings of this work were that both compounds were: effective in the writhing test; reduced paw edema in the carrageenan test; effective in the inflammatory phase of the formalin test corroborating their activity against inflammatory pain conditions; effective on reducing pain through the stimulation of vanilloid receptors sensible to capsaicin (an important pathway for chronic pain maintenance); reduced the pain stimulus caused by PGE2 injection (a pathway involved in chronic pain hypersensitivity); effective on decreasing mechanical allodynia in the CFA-model, demonstrating their potential use against chronic pain disorders.
