Contribution of Spathulenol to the anti-nociceptive effects of Psidium guineense
Nutr Neurosci 2022 Apr;25(4):812-822.PMID:32912110DOI:10.1080/1028415X.2020.1815330.
Objectives: Araçá-verdadeiro is the popular name of Psidium guineense (Myrtaceae), whose fruits and leaves are used in Brazilian folk medicine for treatment of inflammation and pain. The focus of the present research was an investigation of the anti-nociceptive, and anti-inflammatory effects of the essential oil from P. guineense (EOPG) leaves, and of Spathulenol. The anxiolytic and antidepressive effects associated with chronic pain were also investigated in models of acute or persistent nociception or/and inflammatory pain.Methods and Results: Oral treatment with EOPG (10-100 mg/kg) or Spathulenol (10 mg/kg) significantly inhibited formalin-induced nociceptive responses, both sensitivity to cold and edema. Oral treatment with EOPG (10 mg/kg) and Spathulenol (10 mg/kg) did not reduce locomotor activity (open field test). Local administration of Spathulenol (1000 µg/paw) significantly prevented formalin-induced nociceptive sensitivity to cold and paw edema, and carrageenan-induced mechanical hyperalgesia, paw edema and sensitivity to cold. In the Freund's complete adjuvant (CFA) model, oral treatment with EOPG (10 mg/kg) or Spathulenol (10 mg/kg) for 21 days significantly inhibited all analyzed parameters. The percentage maximal inhibition by Spathulenol was 76.00% (mechanical hyperalgesia), 71.90% (cold response), 85.00% (edema), 77.16% (myeloperoxidase activity), 97.72% (time in the closed arms in the elevated plus maze), and 49.00% (immobility time in the tail suspension test), in the CFA model. Models employed male Swiss mice, except for the CFA test, which employed C57bL6 male mice (n=6 /group).Conclusion: This study demonstrates that EOPG is an anti-nociceptive and anti-hyperalgesic agent, in acute and continuous treatment, and an anxiolytic and antidepressive agent when tested with the chronic pain experimental state.
Identification of Spathulenol in Salvia mirzayanii and the immunomodulatory effects
Phytother Res 2011 Apr;25(4):557-62.PMID:20857430DOI:10.1002/ptr.3289.
The methanol extract of Salvia mirzayanii has shown an immunomodulatory effect on peripheral blood lymphocytes. Bioassay-guided fractionation using a lymphocyte proliferation assay on Salvia mirzayanii was performed in order to purify and identify the active compounds. Fractionation of the methanol extract and purification of the components using normal column chromatography and preparative thin layer chromatography resulted in identification of the bioactive compound, Spathulenol, with an immunoinhibitory effect. Identification of this compound was performed by 1D and 2D NMR methods and HRMS. Treatment of activated lymphocytes with a concentrated fraction containing 62% of Spathulenol (SP) showed a decrease in the proliferation of lymphocytes with an IC(50) of 85.4 ± 11.08 µg/mL. Flow cytometry analysis using annexin V and propidium iodide staining of the stimulated peripheral blood lymphocytes in the presence of SP demonstrated a dose dependent increase in the percentage of apoptotic cells (IC(50) ; 77.2 ± 5.31 µg/mL). No significant increase in caspase 3 activity in a 20 h treatment of stimulated lymphocytes compared with the control was observed. In conclusion, this study identified the possible activity of Spathulenol as one of the immunomodulatory compounds present in Salvia mirzayanii. SP showed the capacity to inhibit proliferation in the lymphocytes and to induce apoptosis in these cells possibly through a caspase-3 independent pathway.
(+)-Isobicyclogermacrenal and Spathulenol from Aristolochia yunnanensis alleviate cardiac fibrosis by inhibiting transforming growth factor β/small mother against decapentaplegic signaling pathway
Phytother Res 2019 Jan;33(1):214-223.PMID:30375049DOI:10.1002/ptr.6219.
Cardiac fibrosis contributes to both systolic and diastolic dysfunction in many cardiac pathophysiologic conditions. Antifibrotic therapies are likely to be a crucial strategy in curbing many fibrosis-related cardiac diseases. In our previous study, an ethyl acetate extract of a traditional Chinese medicine Aristolochia yunnanensis Franch. was found to have a therapeutic effect on myocardial fibrosis in vitro and in vivo. However, the exact chemicals and their mechanisms responsible for the activity of the crude extract have not been illustrated yet. In the current study, 10 sesquiterpenoids (1-10) were isolated from the active extract, and their antifibrotic effects were systematically evaluated in transforming growth factor β 1 (TGFβ1)-stimulated cardiac fibroblasts and NIH3T3 fibrosis models. (+)-Isobicyclogermacrenal (1) and Spathulenol (2) were identified as the main active components, being more potent than the well-known natural antifibrotic agent oxymatrine. Compounds 1 and 2 could inhibit the TGFβ1-induced cardiac fibroblasts proliferation and suppress the expression of the fibrosis biomarkers fibronectin and α-smooth muscle actin via down-regulation of their mRNA levels. The mechanism study revealed that 1 and 2 could inhibit the phosphorylation of TGFβ type I receptor, leading to the decrease of the phosphorylation levels of downstream Smad2/3, then consequently blocking the nuclear translocation of Smad2/3 in the TGFβ/Smad signaling pathway. These findings suggest that 1 and 2 may serve as promising natural leads for the development of anticardiac fibrosis drugs.
Antioxidant, anti-inflammatory, antiproliferative and antimycobacterial activities of the essential oil of Psidium guineense Sw. and Spathulenol
J Ethnopharmacol 2018 Jan 10;210:351-358.PMID:28844678DOI:10.1016/j.jep.2017.08.030.
Ethnopharmacological relevance: Leaves from Psidium guineense Sw. are used in popular medicine for the treatment of inflammatory disease. However, there is no scientific evidence demonstrating this activity. Aim of the study: To evaluate the antioxidant, anti-inflammatory, antiproliferative and antimycobacterial activities of the essential oil of P. guineense and Spathulenol (a major constituent). The study was conducted in part to provide evidence supporting the ethnobotanical use of the leaves of this species. Material and methods: The essential oil (EOPG) was extracted from the leaves of P. guineense by hydrodistillation and analysed by gas chromatography-mass spectrometry (GC-MS). The major compound, Spathulenol (PG-1), was isolated in a chromatographic column and characterized by nuclear magnetic resonance (NMR). EOPG and PG-1 were evaluated in vitro for antioxidant activity by DPPH, ABTS and MDA methods; anti-inflammatory potential was assessed using two models, including pleurisy and oedema, in mice. The impact of EOPG and PG-1 on cell proliferation was determined via spectrophotometric quantification of the cellular protein content using a sulforhodamine B assay, and anti-Mycobacterium tuberculosis activity was determined using the REMA method. Results: A total of 38 components were identified from the EOPG, with the sesquiterpenic alcohol Spathulenol (PG-1) (80.7%) being the major constituent. EOPG and PG-1 exhibited the highest antioxidant activities in the DPPH and MDA system compared with reference standard, with IC50 values ranging from 26.13 to 85.60μg/mL. Oral administration of EOPG and PG-1 showed significant inhibition in the Cg-induced mice paw oedema and pleurisy model. The EOPG (GI50 = 0.89μg/mL) and PG-1 (GI50 = 49.30μg/mL) were particularly effective against the ovarian cancer cell line. Both showed moderate antimycobacterial activity. Conclusion: For the first time, this study demonstrated the antioxidant, anti-inflammatory, antiproliferative and antimycobacterial properties of the essential oil of P. guineense (leaves were collected in Dourados-MS) and Spathulenol, collaborating the etnhopharmacologycal use of this plant due to its an anti-inflammatory effect.
Biomimetic synthesis of (+)-ledene, (+)-viridiflorol, (-)-palustrol, (+)-spathulenol, and psiguadial A, C, and D via the platform terpene (+)-bicyclogermacrene
Chemistry 2014 Aug 18;20(34):10654-60.PMID:24867775DOI:10.1002/chem.201403082.
(+)-Bicyclogermacrene is a strained bicyclic and common sesquiterpene found in several essential oils. A short and good yielding synthesis of bicyclogermacrene proceeding in seven steps is reported. This terpene is used as key platform intermediate for a biomimetic access to several aromadendrene sesquiterpenoids, such as ledene, viridiflorol, palestrol, and Spathulenol. Furthermore, bicyclogermacrene is shown to be the terpene component in the synthesis of the meroterpenoids psiguadial A, C, and D.
