Ganoderic acid B attenuates LPS-induced lung injury
Int Immunopharmacol 2020 Nov;88:106990.PMID:33182051DOI:10.1016/j.intimp.2020.106990.
Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is a serious respiratory disease, the mechanism is unclear. This paper revealed the mechanism of Ganoderic acid B (BB) on lipopolysaccharide-induced pneumonia in mice. Pneumonia model was induced by LPS in mice and A549 cells. Lung dry/wet weight (W/D) and myeloperoxidase (MPO) activity in lung were examined. Lung histopathological changes was observed by HE staining. Superoxide dismutase (SOD), malondialdehyde (MDA) and proinflammatory cytokines, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in mice and A549 cells were detected. Rho/NF-κB pathway in mice and A549 cells were examined by Western Blot. BB significantly reduced W/D and MPO activity, restored lung histopathological changes. BB also increased SOD, decreased MDA, TNF-α, IL-1β and IL-6 in mice and A549 cells. In addition, BB inhibited Rho/NF-κB pathway in mice and A549 cells. BB has protective effect on LPS-induced pneumonia in mice, and its mechanism is related to the regulation of Rho/NF-κB signaling pathway.
Ganoderic acid B's influence towards the therapeutic window of trifluoperazine (TFP)
Afr Health Sci 2015 Mar;15(1):146-9.PMID:25834543DOI:10.4314/ahs.v15i1.20.
Background: Ganoderic acid B is an important bioactive ingredient isolated from Ganoderma lucidum, and exhibits various pharmacological activities. Aims: To investigate the influence of Ganoderic acid B towards the therapeutic window of trifluoperazine (TFP). Methods: In vitro human liver microsomes (HLMs) incubation system was used to determine the inhibition of Ganoderic acid B towards the glucuronidation of trifluoperazine (TFP). Results: Ganoderic acid B exerted concentration-dependent inhibition towards the glucuronidation of TFP. Furthermore, Dixon plot was used to determine the inhibition type. The intersection point was located in the second quadrant in Dixon plot, indicating the competitive inhibition of Ganoderic acid B towards TFP glucuronidation. Through fitting the data using competitive nonlinear fitting equation, the inhibition kinetic parameter was calculated to be 56.7 uM. Conclusion: All this data indicated the potential influence of Ganoderic acid B-containing herbs towards therapeutic window of TFP. Given that the glucuronidation reaction of TFP is the probe reaction of UGT1A4, the data obtained from the present study also indicated the potential influence of Ganoderic acid-containing herbs towards the therapeutic window of drugs mainly undergoing UGT1A4-mediated metabolism.
Time-dependent dual beneficial modulation of interferon-γ, interleukin 5, and Treg cytokines in asthma patient peripheral blood mononuclear cells by Ganoderic acid B
Phytother Res 2022 Mar;36(3):1231-1240.PMID:35112740DOI:10.1002/ptr.7266.
Th2 cytokines play a dominant role in the pathogenesis of allergic asthma. Interferon gamma (IFN-γ), a Th1 cytokine, links to therapeutic mechanisms of allergic asthma. Interleukin (IL)-10, a regulatory cytokine, is involved in the induction of immune tolerance. We previously demonstrated that Anti-Asthma Simplified Herbal Medicine Intervention (ASHMI) suppressed Th2 and increased IFN-γ in patients with asthma and in animal models, but its bioactive compound is unknown. Ganoderic acid beta (GAB) was isolated from Ganoderma lucidum (one herb in ASHMI). Human peripheral blood mononuclear cells (PBMCs) from adult patients with asthma were cultured with GAB or dexamethasone (Dex) in the presence of environmental allergens. The cytokine levels of IL-10, IFN-γ, IL-5, transcription factors T-bet, Foxp-3, and GATA3 were measured. Following 3-day culture, GAB, but not Dex, significantly increased IL-10 and IFN-γ levels by allergic patients' PBMCs. Following 6-day treatment, GAB inhibited IL-5 production, but IL-10 and IFN-γ remained high. Dex suppressed production of all three cytokines. GAB suppressed GATA3 and maintained Foxp-3 and T-bet gene expression, while Dex significantly suppressed GATA3 and T-bet expression. GAB simultaneously increased IL-10, IFN-γ associated with induction of T-bet and Foxp3, while suppressing IL-5, which was associated with suppression of GATA3, demonstrating unique beneficial cytokine modulatory effect, which distinguishes from Dex's overall suppression.
Structural identification of the metabolites of Ganoderic acid B from Ganoderma lucidum in rats based on liquid chromatography coupled with electrospray ionization hybrid ion trap and time-of-flight mass spectrometry
Biomed Chromatogr 2013 Sep;27(9):1177-87.PMID:23723086DOI:10.1002/bmc.2924.
Ganoderic acid B (GAB), a representative triterpenoid in Ganoderma lucidum, possesses various pharmaceutical effects and has been used as a chemical marker in quality control of G. lucidum and related products. The metabolites of GAB in vivo after its oral administration to rats were investigated by liquid chromatography coupled with electrospray ionization hybrid ion trap and time-of-flight mass spectrometry. A total of 14 metabolites of GAB in rat plasma, bile and various organs were detected and identified by direct comparison with the authentic compounds and their characteristic mass fragmentation patterns. The results showed that oxidization and hydroxylation were the common metabolic pathways for GAB in rats. Moreover, some reduction metabolites of GAB were detected in rat kidney and stomach and glucuronidation only appeared in rat bile. This is the first report on the metabolites of GAB in vivo.
Pharmacokinetics of ganoderic acid D and its main metabolite by liquid chromatography-tandem mass spectrometry
J Chromatogr B Analyt Technol Biomed Life Sci 2013 Jul 1;930:1-6.PMID:23692850DOI:10.1016/j.jchromb.2013.04.015.
The present study aims to investigate the pharmacokinetics of ganoderic acid D (GD), a representative active triterpenoid from Ganoderma lucidum. A sensitive and selective liquid chromatography-tandem mass spectrometry method was developed for the simultaneous determination of the concentrations of GD and its main metabolite (Ganoderic acid B) in rat plasma. Following protein precipitation, the analytes were separated on a reversed-phase C18 column. Acetonitrile-water-acetic acid (40:60:0.01) was used at a flow-rate of 0.2ml/min. A triple quadrupole mass spectrometer equipped with an electrospray ionization source was used as the detector and was operated in the negative ion mode. Multiple reaction monitoring using the characteristic transitions was performed to quantify the analytes. The method had a lower limit of quantification of 8.19ng/ml for GD, and 8.59ng/ml for Ganoderic acid B (GB). The calibration curves were demonstrated to be linear over the concentration range of 8.19-4096ng/ml and 8.59-2149ng/ml, respectively. Variations within- and between-batch were less than 6.4% and 4.6%, respectively. The extraction recovery rates ranged from 98.8 to 105.2% and 100.7 to 113.6%, respectively. The validated method was successfully applied to the quantification of GD and GB concentrations in rat plasma after oral administration (or intravenous administration) of GD preparations at a dose of 15mg/kg. The data showed that the absolute bioavailability increased from 22% to 70% after the GD suspension was changed to GD loaded solid lipid nanoparticles. In the meantime, the Cmax increased from 107.2 to 1555.6ng/ml; the tmax changed from 2.0h to 0.3h. These results are very helpful in the further studies.
