Isolation, characterization and pharmacological potentials of methanol extract of Cassia fistula leaves: Evidenced from mice model along with molecular docking analysis. Heliyon 2024; 10:e28460. [PMID: 38590868 PMCID: PMC10999937 DOI: 10.1016/j.heliyon.2024.e28460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 03/17/2024] [Accepted: 03/19/2024] [Indexed: 04/10/2024] Open
Abstract
The purpose of the current investigation was to conduct a detailed analysis of the chemical components and medicinal properties of the methanolic crude extract derived from the leaves of Cassia fistula. This analysis was carried out using both experimental (in vivo) and computational (in silico) methods. Eleven chemicals were chromatographically isolated using GC-MS/MS, which utilizes a library of NIST and Wiley 2020 versions. FTIR analysis of the extract was performed to identify the functional group of the compounds. The glucose-lowering capacity, analgesic, and anti-diarrheal activities of methanolic crude extract were analyzed utilizing a well-known oral glucose tolerance test, tail immersion method, writhing assay, and castor oil-induced diarrheal mice methods, respectively. After 60 min, 120 min, and 180 min of loading the drugs, a significant reduction of blood glucose levels was examined (p < 0.05) in all the extracts of this plant (200 mg/kg, 400 mg/kg and 600 mg/kg) utilized in this research at a time-dependent manner. Similarly, all the crude extracts showed significant (p < 0.05) effects against pain centrally and peripherally compared to the standard drug morphine (2 mg/kg bw) and diclofenac sodium (50 mg/kg bw). Moreover, the methanol extract (400 mg/kg bw) manifested anti-diarrheal efficacy by inhibiting 72.0 % of the diarrheal episode in mice compared to the standard drug loperamide (inhibition = 80.0%). The results of the computational investigations corroborated existing in-vivo findings. Greater or close to equivalent binding affinity to the active binding sites of kappa opioid receptor, glucose transporter 3 (GLUT 3), and cyclooxygenase 2 was indicative of the potential anti-diarrheal, hypoglycemic, and analgesic characteristics of the isolated compounds (COX-2). Moreover, anticancer and antimicrobial potentiality was also found impressive through evaluation of binding affinity with epidermal growth factor receptor (EGFR) and dihydrofolate reductase (DHFR) receptors. Results from this study indicated that C. fistula might be a beneficial natural resource for treating diarrhea, hyperglycemia, and pain. However, additional research is required to conduct a comprehensive phytochemical screening and establish precise action mechanisms of the crude extract or the plant-derived compounds.

Abstract
Pain is associated with many health problems and a reduced quality of life and has been a common reason for seeking medical attention. Several therapeutics are available on the market, although side effects, physical dependence, and abuse limit their use. As the process of pain transmission and modulation is regulated by different peripheral and central mechanisms and neurotransmitters, 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 due to their chemical structural variety and different analgesic mechanisms. Numerous studies suggested that some chemicals from medicinal plants could be alternative options for pain relief and management. Previously, we conducted a literature search aimed at identifying natural products interacting either directly or indirectly with opioid receptors. In this review, instead, we have made an excursus including active ingredients derived from plants whose mechanism of action appears from the literature to be other than the modulation of the opioid system. These substances could, either by themselves or through synthetic and/or semi-synthetic derivatives, be investigated in order to improve their pharmacokinetic characteristics and could represent a valid alternative to the opioid approach to pain therapy. They could also be the basis for the study of new mechanisms of action in the approach to this complex and disabling pathology.

Abstract
Background: Treatment effect of current pharmacotherapies for migraine is unsatisfying. Discovering new anti-migraine natural products and nutraceuticals from large collections of Chinese medicine classical literature may assist to address this gap.Methods: We conducted a comprehensive search in the Encyclopedia of Traditional Chinese Medicine (version 5.0) to obtain migraine-related citations, then screened and scored these citations to identify clinical management of migraine using oral herbal medicine in history. Information of formulae, herbs and symptoms were further extracted. After standardisation, these data were analysed using frequency analysis and the Apriori algorithm. Anti-migraine effects and mechanisms of actions of the main herbs and formula were summarised.Results: Among 614 eligible citations, the most frequently used formula was chuan xiong cha tiao san (CXCTS), and the most frequently used herb was chuan xiong. Dietary medicinal herbs including gan cao, bai zhi, bo he, tian ma and sheng jiang were identified. Strong associations were constructed among the herb ingredients of CXCTS formula. Symptoms of chronic duration and unilateral headache were closely related with herbs of chuan xiong, gan cao, fang feng, qiang huo and cha. Symptoms of vomiting and nausea were specifically related to herbs of sheng jiang and ban xia.Conclusion: The herb ingredients of CXCTS which presented anti-migraine effects with reliable evidence of anti-migraine actions can be selected as potential drug discovery candidates, while dietary medicinal herbs including sheng jiang, bo he, cha, bai zhi, tian ma, and gan cao can be further explored as nutraceuticals for migraine.

AVICENNA JOURNAL OF PHYTOMEDICINE 2021; 11:494-504. [PMID: 34745921 PMCID: PMC8554284 DOI: 10.22038/ajp.2021.18038] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 03/22/2021] [Accepted: 04/04/2021] [Indexed: 11/06/2022]
Abstract
Objective: Several species of Pinus have shown anti-nociceptive and anti-inflammatory properties. This study was aimed to evaluate anti-nociceptive and anti-inflammatory effects of hydroalcoholic extract of bark and essential oil of leaves of P. eldarica in animal models. Materials and Methods: Hydroalcoholic extract of bark and essential oil of leaves of P. eldarica were prepared and phenolic content and essential oil composition were analyzed using Folin-Ciocalteu method and GC/MS, respectively. Anti-nociceptive effect was assessed using acetic acid, formalin and hot plate tests in male Swiss mice (25-30 g) and for evaluation of anti-inflammatory activity, carrageenan test in male Wistar rats (180-200 g) and croton oil-induced ear edema in male mice, were used. Involvement of opioid, α2-adrenergic, 5-HT3 receptors and adenosine triphosphate (ATP)-dependent K+ channels in pain relief was tested using naloxone, ondansetron, yohimbine and glibenclamide. Results: The total phenolic content of the extract in terms of gallic acid equivalent was 404.9±7.7 mg/g of the extract powder. P. eldarica hydroalcoholic extract (200 and 400 mg/kg) and essential oil (100 and 200 µl/kg) significantly (all, p<0.001) decreased pain behavior in acetic acid and formalin tests but not in hot plate test. The extract and essential oil suppressed edema in carrageenan and croton tests. Glibenclamide partially reversed the anti-nociceptive effect of hydroalcoholic extract while the other antagonists were ineffective. Conclusion: Hydroalcoholic extract of bark and essential oil of leaves of P. eldarica significantly decreased acute and chronic pain as well as inflammation. ATP-dependent K+ channels mediate a part of the observed anti-nociceptive effect.

Abstract
Purpose: This study aims to assess the influence of superficial heat and Biofreeze on pain,
mouth opening (mm), and quality of life in patients with masticatory myofascial
pain syndrome (MPS). Materials and methods: 52 patients with MPS were included in the study. They were randomly divided into
two groups. Patients in the Biofreeze group (n = 26) applied 3.5% menthol gel to the
masseter and temporal muscles twice a day for seven days, while the other group
applied superficial heat. Baseline, 7th, and 21st days of VAS, mouth opening (mm),
and Oral Health Impact Profile-14 (OHIP-14) scores of the patients were evaluated
statistically. Results: The mouth opening increased by 4.27 ± 3.80 mm in the Biofreeze group and 2.58
± 2.16 mm in the superficial heat group. In each group, a significant decrease in
VAS and OHIP-14 scores was observed on the 7th day compared to the baseline
values (p<0.001). There was no statistically significant difference between the two
applications on myofascial pain, mouth opening (mm), and OHIP-14 total score
variables. The favorable effects of both applications on these parameters were
limited to the duration of use. Conclusion: Biofreeze and superficial heat in MPS were found to increase the quality of life, but
the limited effectiveness of these applications underlines the importance of the
underlying factors.

Abstract
Anacardic acid (AA), a compound extracted from cashew nut liquid, exhibits numerous pharmacological activities. The aim of the current investigation was to assess the anti-inflammatory, antinociceptive, and antioxidant activities of AA in mouse models. For this, Swiss albino mice were pretreated with AA (10, 25, 50 mg/kg, intraperitoneally, ip) 30 min prior to the administration of carrageenan, as well as 25 mg/kg of prostaglandin E2, dextran, histamine, and compound 48/80. The antinociceptive activity was evaluated by formalin, abdominal, and hot plate tests, using antagonist of opioid receptors (naloxene, 3 mg/kg, ip) to identify antinociceptive mechanisms. Results from this study revealed that AA at 25 mg/kg inhibits carrageenan-induced edema. In addition, AA at 25 mg/kg reduced edema and leukocyte and neutrophilic migration to the intraperitoneal cavity, diminished myeloperoxidase activity and malondialdehyde concentration, and increased the levels of reduced glutathione. In nociceptive tests, it also decreased licking, abdominal writhing, and latency to thermal stimulation, possibly via interaction with opioid receptors. Taken together, these results indicate that AA exhibits anti-inflammatory and antinociceptive actions and also reduces oxidative stress in acute experimental models, suggesting AA as a promising compound in the pharmaceutical arena.

Abstract
Medicinal plants from traditional chinese medicine are used increasingly worldwide for their benefits to health and quality of life for the relevant clinical symptoms related to pain. Among them, Salvia miltiorrhiza Bunge is traditionally used in asian countries as antioxidant, anticancer, anti-inflammatory and analgesic agent. In this context, several evidences support the hypothesis that some tanshinones, in particular cryptotanshinone (CRY), extracted from the roots (Danshen) of this plant exhibit analgesic actions. However, it is surprisingly noted that no pharmacological studies have been carried out to explore the possible analgesic action of this compound in terms of modulation of peripheral and/or central pain. Therefore, in the present study, by using peripheral and central pain models of nociception, such as tail flick and hot plate test, the analgesic effect of CRY in mice was evaluated. Successively, by the aim of a computational approach, we have evaluated the interaction mode of this diterpenoid on opioid and cannabinoid system. Finally, CRY was dosed in mice serum by an HPLC method validated according to European Medicines Agency guidelines validation rules. Here, we report that CRY displayed anti-nociceptive activity on both hot plate and tail flick test, with a prominent long-lasting peripheral analgesic effect. These evidences were indirectly confirmed after the daily administration of the tanshinone for 7 and 14 days. In addition, the analgesic effect of CRY was reverted by naloxone and cannabinoid antagonists and amplified by arginine administration. These findings were finally supported by HPLC and docking studies, that revealed a noteworthy presence of CRY on mice serum 1 h after its intraperitoneal administration and a possible interaction of tested compound on μ and k receptors. Taken together, these results provide a new line of evidences showing that CRY can produce analgesia against various phenotypes of nociception with a mechanism that seems to be related to an agonistic activity on opioid system.

Abstract
Alternate forms of drug crystals display different physicochemical properties. These include stability, dissolution rate, bioavailability and solubility, which can affect pharmacokinetics and pharmacodynamics. It is therefore important to compare the crystal forms of cedrol to obtain optimal anti-inflammatory and analgesic effects. This study, for the first time, obtained and reports three novel forms (I-III) of cedrol polymorphs. The three forms of cedrol were recrystallized from seven organic solvents by slow cooling or volatilization and identified by thermal analysis, fourier transform infrared spectroscopy, scanning electron microscopy and powder X-ray diffraction analysis. Form I originated from acetone and cyclohexane. Form II was obtained from ethanol, ethyl acetate, acetonitrile and n-hexane. Form III was recrystallized from methanol. The anti-inflammatory and analgesic activities of the three crystalline forms were evaluated by acetic acid induced writhing in mice, the hot plate method, carrageenan induced mouse paw edema models, Xylene-induced mouse ear edema models and cotton pellet-induced mouse granuloma models. Experimental results revealed that the highest performance was achieved from Form I. These findings are of great significance during the early research study of cedrol polymorphs.

[PMID: 31091507 PMCID: PMC6549587 DOI: 10.3344/kjp.2019.32.2.87] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Revised: 02/28/2019] [Accepted: 03/05/2019] [Indexed: 12/16/2022] Open
Abstract
Background This study was performed in order to examine the effect of intrathecal sec-O-glucosylhamaudol (SOG), an extract from the root of the Peucedanum japonicum Thunb., on incisional pain in a rat model. Methods The intrathecal catheter was inserted in male Sprague-Dawley rats (n = 55). The postoperative pain model was made and paw withdrawal thresholds (PWTs) were evaluated. Rats were randomly treated with a vehicle (70% dimethyl sulfoxide) and SOG (10 μg, 30 μg, 100 μg, and 300 μg) intrathecally, and PWT was observed for four hours. Dose-responsiveness and ED50 values were calculated. Naloxone was administered 10 min prior to treatment of SOG 300 μg in order to assess the involvement of SOG with an opioid receptor. The protein levels of the δ-opioid receptor, κ-opioid receptor, and μ-opioid receptor (MOR) were analyzed by Western blotting of the spinal cord. Results Intrathecal SOG significantly increased PWT in a dose-dependent manner. Maximum effects were achieved at a dose of 300 μg at 60 min after SOG administration, and the maximal possible effect was 85.35% at that time. The medial effective dose of intrathecal SOG was 191.3 μg (95% confidence interval, 102.3–357.8). The antinociceptive effects of SOG (300 μg) were significantly reverted until 60 min by naloxone. The protein levels of MOR were decreased by administration of SOG. Conclusions Intrathecal SOG showed a significant antinociceptive effect on the postoperative pain model and reverted by naloxone. The expression of MOR were changed by SOG. The effects of SOG seem to involve the MOR.

Abstract
WHAT IS KNOWN AND OBJECTIVE Menthol has been used as a non-opioid pain reliever since ancient times. A modern understanding of its molecular mechanism of action could form the basis for generating targets for discovery of novel non-opioid analgesic drugs. METHODS The PubMed database was queried using search words related to menthol, pain and analgesia. The results were limited to relevant preclinical studies and clinical trials and reviews published in English during the past 5 years, which yielded 31 reports. The bibliographies of these articles were sources of additional supporting articles. RESULTS Menthol is a selective activator of transient receptor potential melastatin-8 (TRPM8) channels and is also a vasoactive compound. As a topical agent, it acts as a counter-irritant by imparting a cooling effect and by initially stimulating nociceptors and then desensitizing them. Topically applied menthol may also activate central analgesic pathways. At high concentrations, menthol may generate cold allodynia. WHAT IS NEW AND CONCLUSIONS Recent elucidation of TRPM8 channels has provided a molecular basis for understanding the molecular action of menthol and its ability to produce both a cooling sensation and reduction in pain associated with a wide variety of pain(ful) conditions. The more modern mechanistic understanding of menthol and its pharmacologic mechanism of action may lead to an expanded role for this substance in the search for replacements for opioid analgesics, particularly those that can be applied topically.

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
Previous pharmacological and phytochemical studies showed that, Combretum fragrans F. HOFFM (Combretaceae) is a Cameroonian medicinal plant possessing numerous therapeutic virtues and rich in various active secondary metabolites. In this study, we investigate in vivo anti-nociceptive and anti-inflammatory activity and, in vitro anticancer, anti-TNFα, ROS and NO-inhibitory activities of Combretum A and Combretin B, two triterpenes cycloartane-type isolated from the leaves of Combretum fragrans. The effect on ROS, TNF-α and NO production, anticancer activity and cytotoxicity assay were done using chemiluminescence technique, ELISA kit, colorimetric method, MCF-7 cells and MTT assay, respectively. Antinociceptive and anti-inflammatory activities were estimated using a model of acetic acid, formalin and carrageenan. Combretin A and Combretin B significantly (p < 0.001) inhibited extracellular ROS production. These compounds also significantly (p < 0.001) reduced TNF-α and NO production. Moreover, these compounds decreased cell viability of MCF-7 cell lines. For acetic acid- or formalin-induced pain, as well as carrageenan-induced acute inflammation, Combretin A and Combretin B exhibited significant (p < 0.001) anti-nociceptive and anti-inflammatory activities. Anti-nociceptive, anti-inflammatory and anticancer potential associated with inhibitory effects on ROS, TNFα and NO production in this study show that, Combretin A and Combretin B could be considered as the promising chemotherapeutic agents in breast cancer treatment and inflammatory disease.

Abstract
Aristolochia trilobata L. is an aromatic plant, popularly known as "mil-homens", and its essential oil (EO) is generally used to treat colic, diarrhea and dysentery disorders. We evaluated the antinociceptive effect of A. trilobata stem EO and of its major compound, the (R)-(-)-6-methyl-5-hepten-2-yl acetate (sulcatyl acetate: SA), using acetic acid (0.85%)-induced writhing response and formalin-induced (20 μL of 1%) nociceptive behavior in mice. We also evaluated the EO and SA effect on motor coordination, using the rota-rod apparatus. EO (25, 50 and 100 mg/kg) or SA (25 and 50 mg/kg) reduced nociceptive behavior in the writhing test (p<0.001). EO (100 mg/kg) and SA (25 and 50 mg/kg) decreased the nociception on the first phase of the formalin test (p<0.05). On the second phase, EO (25: p<0.01; 50: p<0.05 and 100 mg/kg: p<0.001) and SA (25 and 50 mg/kg; p<0.001) reduced the nociceptive response induced by formalin. EO and SA were not able to cause changes in the motor coordination of animals. Together, our results suggest that EO has an analgesic profile and SA seems to be one of the active compounds in this effect.

Abstract
BACKGROUND The root of Peucedanum japonicum Thunb., a perennial herb found in Japan, the Philippines, China, and Korea, is used as an analgesic. In a previous study, sec-O-glucosylhamaudol (SOG) showed an analgesic effect. This study was performed to examine the antinociceptive effect of intrathecal SOG in the formalin test. METHODS Male Sprague-Dawley rats were implanted with an intrathecal catheter. Rats were randomly treated with a vehicle and SOG (10 µg, 30 µg, 60 µg, and 100 µg) before formalin injection. Five percent formalin was injected into the hind-paw, and a biphasic reaction followed, consisting of flinching and licking behaviors (phase 1, 0-10 min; phase 2, 10-60 min). Naloxone was injected 10 min before administration of SOG 100 µg to evaluate the involvement of SOG with an opioid receptor. Dose-responsiveness and ED50 values were calculated. RESULTS Intrathecal SOG showed a significant reduction of the flinching responses at both phases in a dose-dependent manner. Significant effects were showed from the dose of 30 µg and maximum effects were achieved at a dose of 100 µg in both phases. The ED50 value (95% confidence intervals) of intrathecal SOG was 30.3 (25.8-35.5) µg during phase 1, and 48.0 (41.4-55.7) during phase 2. The antinociceptive effects of SOG (100 µg) were significantly reverted at both phases of the formalin test by naloxone. CONCLUSIONS These results demonstrate that intrathecal SOG has a very strong antinociceptive effect in the formalin test and it seems the effect is related to an opioid receptor.

Abstract
BACKGROUND This study aims to evaluate the scientific basis of traditional application of Persicaria orientalis for reducing pain and inflammation. METHODS An in vitro method was performed to investigate the presence of the anti-inflammatory activity of methanolic crude extract of P. orientalis. In addition, an in vivo study was conducted in which the hot-plate and tail immersion methods were applied to explore the acute effect of P. orientalis on analgesia. The potency to inhibit chronic inflammation in mice was justified by the carrageenan-induced paw edema and formalin-induced edema methods. For all in vivo testing in animal models (albino mice and rats), plant extract was given via the oral route at doses of 250 mg/kg and 500 mg/kg. RESULTS The methanolic extract of P. orientalis produced a significant (p<0.001) inhibition of analgesia with a prolongation of pain response time by 61.80% at 500 mg/kg. The extract also exhibited a potential anti-inflammatory (56.99%) effect, which was also statistically significant (p<0.001). The present study suggests that the methanolic extract of P. orientalis has potential anti-inflammatory as well as analgesic activity and this extract is effective in the treatment of both acute and chronic pain. CONCLUSIONS Our current study revealed pharmacological properties of the methanolic extract of P. orientalis and also gave a solid scientific platform against its traditional use. The protecting ability of P. orientalis against inflammatory stimuli may be due to phenolic or flavonoid compounds which we have found through phytochemical analysis.

Abstract
BACKGROUND There is a paucity of data regarding the microbial constituents of tobacco products and their impacts on public health. Moreover, there has been no comparative characterization performed on the bacterial microbiota associated with the addition of menthol, an additive that has been used by tobacco manufacturers for nearly a century. To address this knowledge gap, we conducted bacterial community profiling on tobacco from user- and custom-mentholated/non-mentholated cigarette pairs, as well as a commercially-mentholated product. Total genomic DNA was extracted using a multi-step enzymatic and mechanical lysis protocol followed by PCR amplification of the V3-V4 hypervariable regions of the 16S rRNA gene from five cigarette products (18 cigarettes per product for a total of 90 samples): Camel Crush, user-mentholated Camel Crush, Camel Kings, custom-mentholated Camel Kings, and Newport Menthols. Sequencing was performed on the Illumina MiSeq platform and sequences were processed using the Quantitative Insights Into Microbial Ecology (QIIME) software package. RESULTS In all products, Pseudomonas was the most abundant genera and included Pseudomonas oryzihabitans and Pseudomonas putida, regardless of mentholation status. However, further comparative analysis of the five products revealed significant differences in the bacterial compositions across products. Bacterial community richness was higher among non-mentholated products compared to those that were mentholated, particularly those that were custom-mentholated. In addition, mentholation appeared to be correlated with a reduction in potential human bacterial pathogens and an increase in bacterial species resistant to harsh environmental conditions. CONCLUSIONS Taken together, these data provide preliminary evidence that the mentholation of commercially available cigarettes can impact the bacterial community of these products.

Shikimic acid inhibits LPS-induced cellular pro-inflammatory cytokines and attenuates mechanical hyperalgesia in mice. Int Immunopharmacol 2016; 39:97-105. [PMID: 27454847 DOI: 10.1016/j.intimp.2016.07.016] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2016] [Revised: 06/28/2016] [Accepted: 07/16/2016] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND AIMS Shikimic acid (SA) is present in a wide variety of plants and microorganisms used in traditional and folk medicine and also is an essential starting material for the synthesis of the antiviral drug Oseltamivir (Tamiflu®). Some pharmacological actions observed in SA-enriched products include antioxidant and anti-inflammatory activities. Here, we investigated the anti-inflammatory and antinociceptive actions of isolated SA. METHODS RAW 264.7 macrophage cells were treated with bacterial LPS (1μg/mL) and the effect of SA on the modulation of cell viability, nitric oxide (NO) production, TNF-α, and IL-1β content and MAPK (ERK1/2 and p38) activation was evaluated. Besides, the anti-hyperalgesic actions of SA on in vivo model of mechanical hyperalgesia induced by carrageenan (CG), dopamine (DA), TNF-α and prostaglandin (PGE2) were assessed. RESULTS In RAW 264.7 cells, SA suppressed LPS-induced decrease in cell viability and nitrite accumulation to control values and inhibited up-regulation of TNF-α (65%) and IL-1β (39%). These effects may be mediated at least in part by inhibition of LPS-induced ERK 1/2 (22%) and p38 (17%) phosphorylation. In mice, SA at 50, 100, and 200mg/kg decreased formalin-induced nociceptive behavior (around 50%) and inhibited the inflammatory nociception induced by TNF-α and PGE2 (50 to 75% each). Moreover, SA (100 and 200mg/kg) significantly attenuated the mechanical hyperalgesia induced by CG and DA (25 to 40% each). CONCLUSIONS These results indicate that SA presents anti-inflammatory actions with potential for development of drugs to treat pro-inflammatory and painful conditions.

Abstract
Geraniol (GER) is a monoterpene alcohol with various biochemical and pharmacological properties present in the essential oil of more than 160 species of herbs (especially the Cymbopogon genus). In this study, we evaluated the antinociceptive activity of GER in behavioural and electrophysiological in vitro experimental models of nociception using male Swiss mice. GER (12.5, 25 or 50 mg/kg i.p. and 50 or 200 mg/kg p.o.) reduced the number of writhes induced by acetic acid. The opioid antagonist naloxone (5 mg/kg s.c.) administered in mice subsequently treated with GER (25 mg/kg i.p.) did not reverse such antinociceptive activity, suggesting a non-opioid pathway for the mechanism of action. GER (12.5, 25 and 50 mg/kg i.p.) reduced paw licking time in the second phase of the formalin test. Also, in the glutamate test, GER when administered 50 mg/kg i.p. reduced paw licking time, probably modulating glutamatergic neurotransmission. GER blocked reversibly components of the compound action potential (CAP) recorded in isolated sciatic nerve in a concentration- and drug exposure time-dependent manner: 1 mM to 120 min. for the first component and 0.6 mM to 90 min. for the second component. The IC50 was calculated for the peak-to-peak amplitude (PPA) at 0.48 ± 0.04 mM. The conduction velocity was also reduced by exposure to GER starting from the concentration of 0.3 mM for both components of the CAP. In conclusion, it is suggested that GER has antinociceptive activity, especially in pain related to inflammation, and in part related to reduced peripheral nerve excitability.

Scientific investigation of crude alkaloids from medicinal plants for the management of pain. Altern Ther Health Med 2016; 16:178. [PMID: 27296395 PMCID: PMC4906632 DOI: 10.1186/s12906-016-1157-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2015] [Accepted: 06/03/2016] [Indexed: 11/10/2022]
Abstract
BACKGROUND Tissue damage is associated with pain, which is an alarming sign. Aspirin and morphine have been widely used in recent decades for management of pain. Medicinal herbs have been in use for treatment of different diseases for centuries. Many of these herbs possess analgesic activity with relatively less incidences of adverse effects. The strong positive correlation of alkaloids in medicinal plants for analgesic activity persuades an intention to determine possible analgesic activity of total alkaloids extracted from the selected medicinal plants using animal models to answer its possible mechanisms. METHODS Crude alkaloids from selected medicinal plants (Woodfordia fruticosa, Adhatoda vasica, Chenopodium ambrosioides, Vitex negundo, Peganum harmala and Broussonetia papyrifera) were extracted as per reported literature. The test crude alkaloids were screened foracute toxicity study. Writhings induced by acetic acid, tail immersion method and formalin-induced nociception assay procedures were used for possible analgesic effects of the crude alkaloids. RESULTS Crude alkaloids were safe up to dose of 1250 mg/kg body weight in mice. The alkaloids significantly reduced the abdominal constrictions, and increased the time for paw licking response in both phases with a significant raise in latency time in nociception models (P ≤ 0.05). Moreover, the antinociceptive response was significantly attenuated by pretreatment with naloxone suggesting involvement of the opioid receptors for possible antinociceptive action. CONCLUSIONS Crude alkaloids of Woodfordia fruticosa and Peganum harmala showed prominent analgesic potentials through inhibition of peripheral as well as central nervous system mechanisms. Further work is required for isolation of the pharmacologically active constituents.

Abstract
CONTEXT Pain corresponds to the most frequent reason for visits to physicians, and its control by conventional drugs is accompanied by several side effects, making treatment difficult. For this reason, new chemical entities derived from natural products still hold great promise for the future of drug discovery to pain treatment. OBJECTIVE The objective of this study was to evaluate the antinociceptive and anti-inflammatory profiles of p-cymene (PC), a monocyclic monoterpene, and its possible mechanisms of action. MATERIALS AND METHODS Mice treated acutely with PC (25, 50, or 100 mg/kg, i.p.) were screened for carrageenan-induced hyperalgesia and the inflammatory components of its cascade (30-180 min), carrageenan-induced pleurisy (4 h), and tail-flick test (1-8 h). Also, we observed the PC effect on the generation of nitric oxide by macrophages and the activation of neurons in the periaqueductal gray (PAG) by immunofluorescence. RESULTS PC reduced (p < 0.001) the hyperalgesia induced by carrageenan, TNF-α, dopamine, and PGE2. PC decrease total leukocyte migration (100 mg/kg: p < 0.01), neutrophils (50 and 100 mg/kg: p < 0.05 and 0.001), and TNF-α (25, 50, and 100 mg/kg: p < 0.01, 0.05, and 0.001, respectively), besides reducing NO production (p < 0.05) in vitro. PC produced antinociceptive effect in tail-flick test (p < 0.05), which was antagonized by naloxone, naltrindole, nor-BNI, and CTOP, and increased (p < 0.001) the number of c-Fos-immunoreactive neurons in PAG. DISCUSSION AND CONCLUSION These results provide information about the anti-hyperalgesic and anti-inflammatory properties of PC suggesting a possible involvement of the opioid system and modulating some pro-inflammatory cytokines.

Abstract
OBJECTIVES The aim of the study was to investigate the anti-inflammatory, antioxidant and antinociceptive actions of PFPe, a polysaccharide fraction isolated from the dried fruit of the Passiflora edulis. METHODS Animals were pretreated with PFPe (0.3, 1 or 3 mg/kg, i.p.) 1 h before induction of paw oedema by carrageenan, histamine, serotonin, compound 48/80 or prostaglandin E2 (PGE2). Neutrophil migration and vascular permeability were measured after carrageenan injection into the peritoneum, and the action of the PFPe on the tumour necrosis factor-alpha, interleukin-1 beta (IL-1β), myeloperoxidase (MPO), glutathione (GSH) and malondialdehyde (MDA) levels was also evaluated. To assay nociception, we examined acetic acid-induced writhing, formalin-induced paw licking and response latency in the hot plate test. KEY FINDINGS Pretreatment with PFPe significantly inhibited carrageenan-induced paw oedema. PFPe also reduced paw oedema induced by compound 48/80, histamine, serotonin, and PGE2 and compound 48/80-induced vascular permeability. In addition, PFPe significantly reduced the MPO activity, MDA and GSH concentrations, and IL-1β level. In the nociception tests, PFPe reduced acetic acid-induced writhing and formalin-induced paw licking and did not increase the response latency time. CONCLUSIONS Our results suggest that PFPe administration reduces the inflammatory response by modulation of the liberation or synthesis of histamine and serotonin, by reduction of neutrophil migration, IL-1β levels, and oxidative stress and nociception.

Abstract
The present work reports the anti-inflammatory and antinociceptive activities of the ethanol extract obtained from the stem bark of Sterculia striata A. St.-Hil. & Naudin (Ss-EtOH) in the experimental models of edema induced by carrageenan, dextran, or histamin and nociception induced by chemical stimuli, such as acetic acid, formalin, capsaicin, or glutamate. The Ss-EtOH (50 mg/kg) promoted a marked inhibition on the hind paw edema induced by carrageenan or dextran (30% and 73%, respectively). Besides, Ss-EtOH (25 mg/kg) exhibited a slight activity (30%) on the hind paw edema induced by histamin. The Ss-EtOH (12.5 and 25 mg/kg) showed the antinociceptive activity on chemical stimuli induced by acetic acid (65.59% and 38.37%, respectively), formalin, in the initial (35.08% and 31.5%, respectively) and late phases (44.09% and 83.57%, respectively), capsaicin (43.77% and 51.31%, respectively), or glutamate (36.6% and 52.12%, respectively). Regarding the possible mechanism involved in the antinociceptive effect, Ss-EtOH (12.5 mg/kg) showed a decrease in the antinociceptive effect (65.8%) in the acetic acid model after pretreatment with naloxone. Thus, opioid mechanisms might be underlying this response.

Abstract
BACKGROUND Current pain management is limited, in particular, with regard to chronic pain. In an attempt to discover novel analgesics, we combined the approach developed to characterize traditional Chinese medicine (TCM), as part of the "herbalome" project, with the reverse pharmacology approach aimed at discovering new endogenous transmitters and hormones. RESULTS In a plant used for centuries for its analgesic properties, we identify a compound, dehydrocorybulbine (DHCB), that is effective at alleviating thermally induced acute pain. We synthesize DHCB and show that it displays moderate dopamine receptor antagonist activities. By using selective pharmacological compounds and dopamine receptor knockout (KO) mice, we show that DHCB antinociceptive effect is primarily due to its interaction with D2 receptors, at least at low doses. We further show that DHCB is effective against inflammatory pain and injury-induced neuropathic pain and furthermore causes no antinociceptive tolerance. CONCLUSIONS Our study casts DHCB as a different type of analgesic compound and as a promising lead in pain management.

Abstract
Background. In folk medicine, extra virgin olive oil (EVOO) is used as a remedy for a variety of diseases. This study investigates the in vivo antinociceptive, anti-inflammatory, and anti-cancer effects of EVOO on mice and rats. Materials and Methods. In this experimental study, using the acetic acid-induced writhing and formalin tests in mice, the analgesic effect of EVOO was evaluated. Acetylsalicylic acid and morphine were used as standard drugs, respectively. The anti-inflammatory activity was investigated by means of the carrageenan-induced paw edema model in rats using acetylsalicylic acid and dexamethasone as standard drugs. Last, the xenograft model in athymic mice was used to evaluate the anticancer effect in vivo. Results. EVOO significantly decreased acetic acid-induced abdominal writhes and reduces acute and inflammatory pain in the two phases of the formalin test. It has also a better effect than Dexamethasone in the anti-inflammatory test. Finally, the intraperitoneal administration of EVOO affects the growth of HCT 116 tumours xenografted in athymic mice. Conclusion. EVOO has a significant analgesic, anti-inflammatory, and anticancer properties. However, further detailed studies are required to determine the active component responsible for these effects and mechanism pathway.

Abstract
A variety of active constituents with wide range of pharmacological actions have been reported with Centella asiatica. The present study was undertaken to assess analgesic and anti-inflammatory properties of its leaf extracts. Dried leaves were defatted with petroleum ether and extracted with chloroform and methanol. Both chloroform and methanol extracts were evaluated for analgesic activity through tail clip, tail flick, tail immersion, and writhing assay tests at doses of 50, 100, and 200 mg/kg using Swiss albino mice. On the other hand, anti-inflammatory assay was performed by carrageenan induced paw edema of methanol extract at 100 and 200 mg doses in Wistar albino rat. Dextropropoxyphene and indomethacin were employed as a standard for analgesic and anti-inflammatory studies, respectively. Our present study demonstrated that Centella asiatica bears significant analgesic and anti-inflammatory activities in those models.

Abstract
CONTEXT Since the beginning of civilization, herbal medicines have been an important source for human beings to treat their ailments. Despite the large number of synthetic remedies available in the market, the use of plants is seen as a great challenge in the search for new substances endowed with therapeutic properties. One example is Dioclea grandiflora Mart. ex Benth. (Leguminosae) employed in traditional medicine to treat prostate disorders and kidney stones. OBJECTIVES This work presents a brief overview of D. grandiflora, including a description of the plant, its chemical composition and pharmacological properties. METHODS This review gathers information available in the scientific literature compiled from databases such as Science Direct, PubMed, Dr. Dukes Phytochemical and Ethnobotany, Missouri Botanical Garden and The International Plant Names Index. RESULTS The information found in the literature showed that flavonoids are the major constituents of D. grandiflora that account for most of the pharmacological properties so far disclosed. Several studies have revealed that D. grandiflora possesses antinociceptive, cardiovascular, antioxidant and anti-inflammatory activities. CONCLUSION Research shows that D. grandiflora is a potential source of compounds pertaining medicinal applications. It provides an interesting subject in the search for new drugs of natural origin.

Abstract
Introduction Toddalia asiatica is a commonly used medicinal plant in East Africa for the management of pain and inflammatory conditions. The present study investigated the antinociceptive and the anti-inflammatory effects of T. asiatica in Swiss albino mice. Methods The antinociceptive and the anti-inflammatory effects of T. asiatica were investigated using formalin-induced pain test and the carrageenin-induced oedema paw. The extract solvent (vehicle), aspirin and indomethacin were employed as negative and positive controls respectively. Eight mice were used in each experiment. Results In the early phase of the formalin test, the 100mg/kg dose showed no significant antinociceptive activity while the 200mg/kg showed significant (p < 0.01) antinociceptive activity. The 100 mg/kg dose showed highly significant antinociceptive activity (p < 0.001) in the late phase of the formalin test while the 200mg/kg dose showed no significant antinociceptive activity. A reduction in carragenin induced acute inflammation paw oedema was significant (p < 0.01) following administration of 100mg/kg dose but not with the 200mg/kg dose. Conclusion The present study therefore lends support to the anecdotal evidence for use of T. asiatica in the management of painful and inflammatory conditions.

Abstract
The Chir Pine, Pinus roxburghii, named after William Roxburgh, is a pine native to the Himalaya. Pinus roxburghii Sarg. (Pinaceae) is traditionally used for several medicinal purposes in India. As the oil of the plant is extensively used in number of herbal preparation for curing inflammatory disorders, the present study was undertaken to assess analgesic and anti-inflammatory activities of its bark extract. Dried and crushed leaves of Pinus roxburghii Sarg. were defatted with petroleum ether and then extracted with alcohol. The alcoholic extract at the doses of 100 mg/kg, 300 mg/kg, and 500 mg/kg body weight was subjected to evaluation of analgesic and anti-inflammatory activities in experimental animal models. Analgesic activity was evaluated by acetic acid-induced writhing and tail immersion tests in Swiss albino mice; acute and chronic anti-inflammatory activity was evaluated by carrageenan-induced paw oedema and cotton pellet granuloma in Wistar albino rats. Diclofenac sodium and indomethacin were employed as reference drugs for analgesic and anti-inflammatory studies, respectively. In the present study, the alcoholic bark extract of Pinus roxburghii Sarg. demonstrated significant analgesic and anti-inflammatory activities in the tested models.

Abstract
Verticinone, an isosteroidal alkaloid separated from Bulbus Fritillaria (Chinese name "Bei-mu"), was evaluated for its analgesic activities in murine models of inflammatory and neuropathic pain. It was shown that oral administarion of verticinone could significantly inhibit acetic acid-induced writhing response in a dose-dependent way, and the writhing inhibition of 3 mg/kg verticinone was 66.2%, which was approximately higher than that of 200 mg/kg aspirin. In the formalin test, a high dose of (3 mg/kg) verticinone could inhibit the nociceptive response of both phases, but the lower dose (1.5 mg/kg) could only inhibit the second phase response, which suggested that verticinone might exert its analgesic effect through both central and peripheral mechanisms. In addition, in formalin and acetic acid tests, the spontaneous locomotive activities of the mice treated with verticinone were transiently greatly decreased when compared with the vehicle group. In the rat model of paclitaxel induced neuropathic pain, in contrast to the declined analgesic effect of morphine after repeated administration with the same dose, a relatively constant analgesic effect of verticinone was observed. These investigations suggested that verticinone could exert a good antinociceptive effect on inflammatory pain and cancer-related neuropathic pain probably through both peripheral and central mechanisms, and it might be partly involved with some sedation effects. Verticinone is expected to become a potentially novel sedative-analgesic agent without producing tolerance and dependence, but further studies are still urgently needed to elucidate the precise mechanisms and activities of it.

Abstract
The hydroalcoholic extract of Areca catechu L. (ANE) nut was screened for its analgesic, anti-inflammatory and in vitro antioxidant potential. Three doses of ANE (250, 500 and 1000 mg/kg orally) were tested for analgesic and anti-inflammatory activities. Evaluation of analgesic activity of ANE was performed using hot plate and formalin test in mice. ANE showed maximum increase in hot plate reaction time (56.27%, p<0.01), while reduced the duration of licking/biting behaviors in first (39.45%, p<0.05) and second (92.71%, p<0.01) phases of the formalin test indicating significant analgesic activity. ANE reduced the paw edema considerably (86.79% inhibition after 24h, p<0.01) in dose-dependent manner compared to carrageenan-induced rat. In addition, in vitro antioxidant activity of ANE was investigated by total phenolic content (TPC) and hydrogen peroxide assay. The IC(50) observed in hydrogen peroxide assay was 83.14 μg/ml and TPC 120.56±21.09 mg QE/g. Altogether, these results suggest that the hydroalcoholic extract of Areca catechu could be considered as a potential analgesic, anti-inflammatory and antioxidant agent.

Abstract
The science of ethnobotany is reviewed in light of its multi-disciplinary contributions to natural product research for the development of pharmaceuticals and pharmacological tools. Some of the issues reviewed involve ethical and cultural perspectives of healthcare and medicinal plants. While these are not usually part of the discussion of pharmacology, cultural concerns potentially provide both challenges and insight for field and laboratory researchers. Plant evolutionary issues are also considered as they relate to development of plant chemistry and accessing this through ethnobotanical methods. The discussion includes presentation of a range of CNS-active medicinal plants that have been recently examined in the field, laboratory and/or clinic. Each of these plants is used to illustrate one or more aspects about the valuable roles of ethnobotany in pharmacological research. We conclude with consideration of mutually beneficial future collaborations between field ethnobotanists and pharmacologists.

Abstract
Background: Traditional and current opioid pharmacology is fundamentally based on interactions between opioid receptors and compounds isolated from natural sources. Adverse effects associated with opioids have led to the search for compounds with diminished side effects. Discussion: Recent discoveries of non-nitrogenous and structurally diverse alkaloids as novel opioid ligands have led to renewed interest in the development of novel chemotypes for opioid receptors. Conclusion: The strong history of natural products as opioid receptor ligands suggests that nature is one of the most promising for the identification of novel opioids. This review highlights the vast potential of investigating natural products as novel probes of opioid receptors.

Abstract
Pawhuskin A is an isoprenylated stilbene that was isolated from Dalea purpurea and reported to have affinity for the opioid receptor in vitro. It has been synthesized through a convergent sequence that joins a prenylated aldehyde with a geranylated phosphonate in a stereoselective Horner-Wadsworth-Emmons condensation to afford the target E olefin isomer. This synthesis confirms the structure assigned to the natural product and establishes a route that may be used to explore its biological activity and to prepare more active analogues.

Abstract
Protection of salvinorin B as standard alkoxyalkyl ethers yielded highly potent kappa opioid receptor agonists. Ethoxymethyl ether 6 is among the most potent and selective kappa agonists reported to date. Fluoroethoxymethyl ether 11 is the first potent, selective fluorinated kappa ligand, with potential use in MRI and PET studies. Further enlargement of the alkoxy group, alkylation of the acetal carbon, or heteroatom substitution all reduced activity. These protecting groups may prove useful in related work not only by enabling the use of harsher synthetic conditions, but potentially by optimizing the potency of the products.

Abstract
The vanilloid receptor-1 (VR1 or TRPV1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role as an integrator of multiple pain-producing stimuli. From a high-throughput screening assay, measuring calcium uptake in TRPV1-expressing cells, we identified an N-aryl trans-cinnamide (AMG9810, compound 9) that acts as a potent TRPV1 antagonist. We have demonstrated the antihyperalgesic properties of 9 in vivo and have also reported the discovery of novel, orally bioavailable cinnamides derived from this lead. Herein, we expand our investigations and describe the synthesis and biological evaluation of a series of conformationally constrained analogues of the s-cis conformer of compound 9. These investigations resulted in the identification of 4-amino- and 4-oxopyrimidine cores as suitable isosteric replacements for the trans-acrylamide moiety. The best examples from this series, pyrimidines 79 and 74, were orally bioavailable and exhibited potent antagonism of both rat (IC50 = 4.5 and 0.6 nM, respectively) and human TRPV1 (IC50 = 7.4 and 3.7 nM, respectively). In addition, compound 74 was shown to be efficacious at blocking a TRPV1-mediated physiological response in vivo in the capsaicin-induced hypothermia model in rats; however, it was ineffective at preventing thermal hyperalgesia induced by complete Freund's adjuvant in rats.
