(Phyllanthaceae) Ethanolic Extract: Low Acute Oral Toxicity and Antinociceptive Activity. Pharmaceuticals (Basel) 2023; 16:ph16050689. [PMID: 37242472 DOI: 10.3390/ph16050689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 04/14/2023] [Accepted: 04/20/2023] [Indexed: 05/28/2023] Open
Abstract
Margaritaria nobilis L.f. (Phyllanthaceae), a native Brazilian tree occurring mainly in the Amazon, is used in folk medicine for the treatment of abscesses (bark) and cancer-like symptoms (leaves). The present study evaluates the safety of its acute oral administration and its effects on nociception and plasma leakage. The chemical constitution of the leaf's ethanolic extract is determined by ultra-performance liquid chromatography-high-resolution mass spectrometry (LC-MS. Its acute oral toxicity is evaluated in female rats at a dose of 2000 mg/kg, evaluating the occurrence of deaths and Hippocratic, behavioral, hematological, biochemical, and histopathological changes, as well as food and water consumption and weight gain. Antinociceptive activity is evaluated in male mice with acetic-acid-induced peritonitis (APT) and formalin (FT) tests. An open field (OF) test is performed to verify possible interferences in the animals' consciousness or locomotion. LC-MS analysis shows the presence of 44 compounds classified as phenolic acid derivatives, flavonoids and O-glycosylated derivatives, and hydrolyzable tannins. No deaths or significant behavioral, histological, or biochemical changes are observed in the toxicity assessment. In nociception tests, M. nobilis extract significantly reduces abdominal contortions in APT, demonstrating selectivity for inflammatory components (FT second phase), not interfering in neuropathic components (FT first phase) or consciousness and locomotion levels in OF. Additionally, M. nobilis extract inhibits plasma acetic-acid-induced leakage. These data demonstrate the low toxicity of M. nobilis ethanolic extract, as well as its effectiveness in modulating inflammatory nociception and plasma leakage, possibly related to the flavonoids and tannins present in its composition.

[PMID: 37151635 PMCID: PMC10161701 DOI: 10.1016/j.heliyon.2023.e15619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 04/13/2023] [Accepted: 04/18/2023] [Indexed: 05/09/2023] Open
Abstract
Background Lysionotin, a natural flavonoid extracted from Lysionotus pauciflorus Maxim (Gesneriaceae), has several pharmacological effects including anti-bacterial, anti-hypertensive and anti-inflammatory effects. However, its analgesic effect has not been investigated. This study aimed to assess the antinociceptive activity of lysionotin using chemically and thermally induced nociception in a mouse model. Methods The antinociceptive effects of various lysionotin doses (50, 100, 150, and 200 μg/kg) were assessed in mice using the acetic acid-induced writhing test, hot plate test, and formalin-induced paw licking assay. The effects were compared to those of mice treated with acetylsalicylic acid or morphine in the presence or absence of naloxone (an opioid receptor antagonist). Capsaicin- and glutamate-induced paw licking tests were also used to evaluate the involvement of the vanilloid and glutamatergic systems, respectively. Results Lysionotin produced significant dose-dependent inhibition of nociceptive behavior in the acetic acid-induced writhing test, showing 60% inhibition at a dose of 200 μg/kg. Lysionotin also caused a significant increase in the latency period in response to the hot plate test (76.4% at 200 μg/kg), and significantly inhibited both the neurogenic and inflammatory phases in the formalin-induced paw licking test. Naloxone significantly reverses the effect of lysionotin in both hot plate test and formalin-induced paw licking test. Moreover, lysionotin significantly inhibited the neurogenic nociception induced by intraplantar injections of glutamate and capsaicin (57% and 67.2%, respectively at a dose of 200 μg/kg). Thus, lysionotin exhibited peripheral and central antinociception through the modulation of vanilloid receptors, opioid receptors, and the glutamatergic system. Conclusion Lysionotin possesses antinociceptive activity on adult mice that is mediated through both central and peripheral pathways.

He L, Zhou Y, Wan G, Wang W, Zhang N, Yao L. Antinociceptive effects of flower extracts and the active fraction from Styrax japonicus. JOURNAL OF ETHNOPHARMACOLOGY 2022; 284:114779. [PMID: 34715297 DOI: 10.1016/j.jep.2021.114779] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 10/16/2021] [Accepted: 10/22/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Flowers from Styrax japonicus sieb. et Zucc. have been used as a Chinese folk medicine to alleviate pain such as toothache and sore throat. AIM OF THE STUDY To testify the analgesic effect of flowers from Styrax japonicus, analyze components of the active fraction, and investigate the mechanism of analgesia. MATERIALS AND METHODS Flower extracts were obtained by ethanol, petroleum ether and hydrodistillation extraction. Different fractions of ethanol extracts (EE) were isolated by silica gel column chromatography and preparative liquid chromatography. Analgesic effects of EE, petroleum ether extracts (PEE), hydrodistillation extracts (HDE), and fractions of EE were evaluated using hot plate, acetic acid-induced writhing and formalin tests on mice. Components of the active fraction 1 (F1) were determined by the ultrahigh-performance liquid chromatography Q extractive mass spectrometry (UHPLC-QE-MS). Anti-inflammatory and sedative effects involving analgesic mechanisms were evaluated by carrageenan induced hind paw oedema and pentobarbital sodium sleep tests, respectively. In addition, antagonists including naloxone hydrochloride (NXH), flumazenil (FM), SCH23390 (SCH) and WAY100635 (WAY) were used to investigate the possible mechanism of analgesia. Contents of neurotransmitters and relevant metabolites in different brain regions of mice were also quantified by the ultraperformance liquid chromatography with a fluorescence detector (UPLC-FLD). RESULTS EE rather than PEE and HDE at medium and high doses (150 mg/kg and 300 mg/kg) significantly prolonged the latency time of the response of mice to the thermal stimulation in the hot plate test. Moreover, EE significantly decreased number of writhes in the acetic acid-induced writhing test, and reduced licking time in both two phases of the formalin test in a dose-dependent manner. The F1 (50 mg/kg) showed effective antinociceptive responses in all mice models. However, fraction 2 (F2) and fraction 3 (F3) at 50 mg/kg performed no analgesic action. Kaempferol-3-O-rutinoside, isorhamnetin-3-O-rutinoside, pinoresinol-4-O-glucoside, forsythin and arctiin were identified from components of the F1. Furthermore, F1 (50 mg/kg) did not significantly affect hind paw oedema of mice induced by carrageenan but significantly shortened sleep latency and increased sleep duration in the pentobarbital sodium sleep test. In addition, the antinociceptive response of F1 was not affected by NXH in two mice models, but significantly blocked by FM and WAY in the hot plate test. In the formalin test, FM avoided the effect of F1 only in the first phase, while the analgesic activity of F1 was totally suppressed by WAY in both two phases. Otherwise, contents of 5-hydroxytryptamine (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) increased significantly in hippocampus and striatum of mice in the F1 group. CONCLUSION EE from flowers of Styrax japonicus, and F1, the active part isolated from EE, showed significant antinociceptive activities. The analgesic effect of F1 appeared to be related to the sedative effect, partially mediated by the GABAergic system, and highly involved in the serotonergic system. This was the first study confirming the analgesic effect of Styrax japonicus flower, which provided a candidate for the development of non-opioid analgesics.

Evaluation of analgesic, antiamnesic and antidiarrheal potentials of Medicago denticulata extract using animal model. Saudi J Biol Sci 2021; 28:6352-6358. [PMID: 34759754 PMCID: PMC8568719 DOI: 10.1016/j.sjbs.2021.06.095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 05/27/2021] [Accepted: 06/29/2021] [Indexed: 11/21/2022] Open
Abstract
The analgesic, antidiarrheal, and neuro-pharmacological potentials of Medicago denticulata leaves extract were screened in animal models. Potential analgesic response was noted (*P < 0.05, **P < 0.01, ***P < 0.001) in formalin, acetic acid and heat-induced pain models in a dose-dependent manner. Maximum activity by means of writhing inhibition was documented for Medicago denticulata at 300 mg/kg that was found to be 71.79% (17.43 ± 1.31). In first phase, the Medicago denticulata at a dose of 150 and 300 mg/kg showed analgesic activity and reduced the pain by 54.18% (18.39 ± 1.67) and 62.90% (14.89 ± 1.56), respectively. In second phase, the Medicago denticulata at a dose of 150 and 300 mg/kg showed analgesic activity and reduced the pain by 69.48% (19.78 ± 1.44) and 70.89% (18.86 ± 1.58), respectively. In hot plate method, the Medicago denticulata at a dose of 150 and 300 mg/kg showed the maximum response of 61.16% (8.47 ± 1.23) and 67.39% (10.09 ± 1.04), respectively at 60 min. Scopolamine significantly reduces spontaneous alteration in Y-maze model for antiamnesic activity. Medicago denticulata significantly increased the discrimination index in a dose-dependent manner using novel object recognition test (NORT) model. Exploration time in sec for the novel object was increased significantly (P < 0.001) by donepezil decreased for familiar one with a discrimination index (DI) of 62.18%. Medicago denticulata significantly increased the discrimination index by 60.86% and 57.24% at 300 and 150 mg/kg b.w, respectively. The lowest DI of 53.80% at 75 mg/kg was observed in comparison to the amnesic group. The Medicago denticulata significant decreased the elevated levels of acetylcholinesterase (AChE) and malondialdehyde (MDA and enhancing level of acetylcholine (ACh), superoxide dismutase (SOD) and catalase (CAT) acting as an antioxidant agent. Medicago denticulata reduced the total number of diarrheal feces to lesser extent at dose-dependent manner. From the study results, it is suggested that the Medicago denticulata extract possess good analgesic and antiamnesic activity however the antidiarrheal effects of plant were negligible. In the current study, the traditional use of the plant as a source of medicine has been validated.

Constituents of Chamaecrista diphylla (L.) Greene Leaves with Potent Antioxidant Capacity: A Feature-Based Molecular Network Dereplication Approach. Pharmaceutics 2021; 13:pharmaceutics13050681. [PMID: 34068527 PMCID: PMC8150882 DOI: 10.3390/pharmaceutics13050681] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 04/01/2021] [Accepted: 04/06/2021] [Indexed: 01/09/2023] Open
Abstract
Chamaecrista diphylla (L.) Greene (Fabaceae/Caesalpiniaceae) is a herbaceous plant that is widely distributed throughout the Americas. Plants from this genus have been used in traditional medicine as a laxative, to heal wounds, and to treat ulcers, snake and scorpion bites. In the present study, we investigated the chemical composition of Chamaecrista diphylla leaves through a mass spectrometry molecular network approach. The oxygen radical absorbance capacity (ORAC) for the ethanolic extract, enriched fractions and isolated compounds was assessed. Overall, thirty-five compounds were annotated for the first time in C. diphylla. Thirty-two of them were reported for the first time in the genus. The isolated compounds 9, 12, 24 and 33 showed an excellent antioxidant capacity, superior to the extract and enriched fractions. Bond dissociation energy calculations were performed to explain and sustain the antioxidant capacity found. According to our results, the leaves of C. diphylla represent a promising source of potent antioxidant compounds.
