PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 98:153982. [PMID: 35168092 DOI: 10.1016/j.phymed.2022.153982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 01/22/2022] [Accepted: 02/06/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Our early studies performed on aged rats, ovariectomized (OVX) rats and diabetic mice, indicated the calciotropic role of Fructus Ligustri Lucidi (FLL), the fruit of Ligustrum lucidum Ait., in mediating calcium homeostasis which was partially attributed to its stimulation on renal calcium reabsorption. PURPOSE This study aimed to explicate the underlying molecular mechanism and explore the potential bioactive ingredients in FLL. STUDY DESIGN AND METHODS The OVX C57BL/6 J mice were orally administered with low (FL, 75 mg/kg), middle (FM, 225 mg/kg) or high (FH, 675 mg/kg) dose of extract of Fructus Ligustri Lucidi for 10 weeks. The biological properties of trabecular bone were measured by micro-CT and H&E staining. The molecular expression was assessed by immunoblotting and immunostaining. The potential active components were identified by cell membrane chromatography (CMC) and explored in renal tubular cells with Fluo-3/AM fluorescent staining to indicate intracellular calcium level. The male mice fed with high calcium diet (1.2% Ca) and orally treated with active components for 3 weeks. RESULTS Treatment of OVX mice with FLL extract suppressed the elevation in urinary calcium level (FH, 0.081 ± 0.012, vs. OVX, 0.189 ± 0.038 mg/mg), and increased bone mineral density (FH, 62.41 ± 2.57, vs. OVX, 43.72 ± 8.43 mg/ccm) and percentage of trabecular bone area. It also decreased circulating PTH level (FH, 66.69 ± 10.94, vs. OVX, 303.50 ± 26.56 pg/ml) and up-regulated TRPV5 expression in renal cortex of OVX mice as well as enhanced the expression of PTH receptor (PTH1R) and the ratio of p-PKA/PKA. The PKA inhibitor H89 abolished the induction of serum, prepared from rats treated with FLL extract, on PKA/TRPV5 signaling in renal tubular cells. The CMC identified phenol glycosides, including salidroside and oleuropein, which increased intracellular calcium content, promoted expression of PTH1R and TRPV5 and ratio of p-PKA/PKA as well as decreased calcium excretion in urine of mice fed with high calcium diet. CONCLUSION Salidroside and oleuropein are major ingredients contributing to the anti-hypercalciuria effects of FLL via acting on PTH1R/PKA/TRPV5 signaling in kidney. Further translational research would be required.

Abstract
Osteoarthritis (OA), an inflammatory response in chondrocytes, leads to extracellular matrix (ECM) degradation and cartilage destruction. Timosaponin B-II (TB-II) is the main bioactive component of Rhizoma Anemarrhenae with reported antioxidant and anti-inflammatory effects. This study investigated the anti-OA function and mechanism of TB-II on IL-1β-stimulated SW1353 cells and primary rat chondrocytes. We firstly screened the concentration of TB-II in SW1353 cells and primary rat chondrocytes using CCK-8 assay. Thereafter, SW1353 cells and chondrocytes were, respectively, pretreated with TB-II (20 and 40 μg/mL) and TB-II (10 and 30 μg/mL) for 24 h and then stimulated with interleukin 1β (IL-1β, 10 ng/mL) for another 24 hours. Results showed that TB-II suppressed the production of reactive oxygen species, the protein levels of inducible nitric oxide synthase and cyclooxygenase-2 in IL-1β-stimulated SW1353 cells and chondrocytes. IL-1β-induced high secretion levels of nitric oxide and prostaglandin 2, TNF-α, IL-6 and MCP-1 were down-regulated by TB-II treatment, indicating an anti-inflammatory effect of TB-II on OA in vitro condition. Moreover, TB-II weakened the mRNA and protein expression of (matrix metalloproteinase) MMPs including MMP-1, MMP-3, and MMP-13, indicating the protection of TB-II against ECM degradation. Mechanically, TB-II suppressed MAPKs and NF-κB pathways under IL-1β stimulation evidenced by the down-regulated protein expression of p-ERK, p-p38, p-JNK, p-p65 and the reduced translocation of p65 subunit to the nucleus. The present study demonstrated that TB-II might become a novel therapeutic agent for OA treatment through repressing IL-1β-stimulated inflammation, oxidative stress and ECM degradation via suppressing the MAPKs and NF-κB pathways.

Investigating interactions between chloroquine/hydroxychloroquine and their single enantiomers and angiotensin-converting enzyme 2 by a cell membrane chromatography method. J Sep Sci 2021; 45:456-467. [PMID: 34729910 PMCID: PMC8661882 DOI: 10.1002/jssc.202100570] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 10/27/2021] [Accepted: 10/27/2021] [Indexed: 12/28/2022]
Abstract
Chloroquine and hydroxychloroquine have been studied since the early clinical treatment of SARS‐CoV‐2 outbreak. Considering these two chiral drugs are currently in use as the racemate, high‐expression angiotensin‐converting enzyme 2 cell membrane chromatography was established for investigating the differences of two paired enantiomers binding to angiotensin‐converting enzyme 2 receptor. Molecular docking assay and detection of SARS‐CoV‐2 spike pseudotyped virus entry into angiotensin‐converting enzyme 2‐HEK293T cells were also conducted for further investigation. Results showed that each single enantiomer could bind well to angiotensin‐converting enzyme 2, but there were differences between the paired enantiomers and corresponding racemate in frontal analysis. R‐Chloroquine showed better angiotensin‐converting enzyme 2 receptor binding ability compared to S‐chloroquine/chloroquine (racemate). S‐Hydroxychloroquine showed better angiotensin‐converting enzyme 2 receptor binding ability than R‐hydroxychloroquine/hydroxychloroquine. Moreover, each single enantiomer was proved effective compared with the control group; compared with S‐chloroquine or the racemate, R‐chloroquine showed better inhibitory effects at the same concentration. As for hydroxychloroquine, R‐hydroxychloroquine showed better inhibitory effects than S‐hydroxychloroquine, but it slightly worse than the racemate. In conclusion, R‐chloroquine showed better angiotensin‐converting enzyme 2 receptor binding ability and inhibitory effects compared to S‐chloroquine/chloroquine (racemate). S‐Hydroxychloroquine showed better angiotensin‐converting enzyme 2 receptor binding ability than R‐hydroxychloroquine/hydroxychloroquine (racemate), while the effect of preventing SARS‐CoV‐2 pseudovirus from entering cells was weaker than R‐hydroxychloroquine/hydroxychloroquine (racemate).

Timosaponin BII improved osteoporosis caused by hyperglycemia through promoting autophagy of osteoblasts via suppressing the mTOR/NFκB signaling pathway. Free Radic Biol Med 2021; 171:112-123. [PMID: 33992678 DOI: 10.1016/j.freeradbiomed.2021.05.014] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 04/22/2021] [Accepted: 05/07/2021] [Indexed: 12/14/2022]
Abstract
Defective autophagy occurred in osteoblasts under stress induced by high glucose and played an essential role in the development of diabetic osteoporosis. Timosaponin BII, a steroidal saponin isolated from the rhizomes of Anemarrhena asphodeloides Bunge, possessed anti-osteoporosis properties. In this study, we investigated the efficacy and mechanism of timosaponin BII on diabetic osteoporosis. Timosaponin BII attenuated the deterioration in the microarchitecture of the tibias in diabetic rats. Furthermore, treatment with timosaponin BII dose-dependently reduced hyperglycemia-induced cell apoptosis in primary osteoblasts from rat calvaria. High glucose-exposed osteoblasts exhibited increased mitochondrial superoxide level, decreased mitochondrial membrane potential and impaired autophagic flux, which was attenuated by timosaponin BII, as evidenced by the upregulation of autophagosome numbers, LC3B puncta formation and Beclin1 expression. The antiapoptotic and antioxidative effect of timosaponin BII were repressed by the autophagy inhibitor 3-methyladenine and enhanced by the autophagy inducer rapamycin. Further studies showed that timosaponin BII suppressed the phosphorylation of mTOR and S6K, as well as the downstream factors NFκB and IκB, consequently activating autophagy and decreasing apoptosis. Of note, coincubation of timosaponin BII with MHY1485, a pharmacological activator of mTOR, diminished the protein expression of Bcl2 induced by timosaponin BII, which was in parallel with decreased autophagy and increased phosphorylation of NFκB and IκB. Overexpression of NFκB reduced timosaponin BII-evoked autophagy and promoted apoptosis. The in vivo results showed that oral administration of timosaponin BII downregulated the phosphorylation of mTOR and NFκB and upregulated Beclin1 expression in the proximal tibias of diabetic rats. These results suggested that timosaponin BII attenuated high glucose-induced oxidative stress and apoptosis through activating autophagy by inhibiting mTOR/NFκB signalling in osteoblasts.

Wang N, Xu P, Wang X, Yao W, Wang B, Wu Y, Shou D. Timosaponin AIII attenuates inflammatory injury in AGEs-induced osteoblast and alloxan-induced diabetic osteoporosis zebrafish by modulating the RAGE/MAPK signaling pathways. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2020; 75:153247. [PMID: 32502823 DOI: 10.1016/j.phymed.2020.153247] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 05/12/2020] [Accepted: 05/14/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Advanced glycation end products (AGEs) deposition causes inflammatory injury in osteoblasts and contributes to diabetic osteoporosis. The receptor for advanced glycation end product/mitogen-activated protein kinase pathway (RAGE/MAPK) signaling pathway is closely linked to the pathogenesis of diabetic osteoporosis. Timosaponin AIII, a steroidal saponin isolated from Anemarrhena asphodeloides Bunge (Asparagaceae), shows anti-inflammatory and anti-osteoporosis effects. PURPOSE The present study was aimed to investigate the therapeutic effects of timosaponin AIII on diabetic osteoporosis and whether its effect is dependent on protecting osteoblasts against AGEs-induced injury via RAGE/MAPK signaling suppression. METHODS An alloxan-induced diabetic osteoporosis zebrafish model was applied to investigate the effects of timosaponin AIII in vivo, and alendronate was used as a positive control. Moreover, related mechanisms were explored in primary rat osteoblasts. Molecular docking was applied to investigate the interactions between timosaponin AIII and RAGE. RESULTS Timosaponin AIII treatment reversed alloxan-induced reduction in the mineralized area of the larvae head skeleton, accompanied by a decreased level of triglyceride and total cholesterol in the zebrafish. Additionally, AGEs significantly influenced RAGE expression, alkaline phosphatase activity, interleukin 1β expression, interleukin 6 expression, and tumor necrosis factor-α expression, and increased cell apoptosis. Timosaponin AIII significantly downregulated AGEs-induced interleukin 1β, interleukin 6, and tumor necrosis factor-α levels, and upregulated alkaline phosphatase and osteocalcin levels. Timosaponin AIII also significantly reduced the expression of RAGE and had additive effects on downstream P38, extracellular signal-regulated kinase and c-Jun N-terminal kinase in AGEs-induced osteoblast. Molecular docking predicted that hydrogen and hydrophobic interactions occurred between timosaponin AIII and RAGE. CONCLUSION These data clarified that timosaponin AIII attenuates diabetic osteoporosis via a novel mechanism involved suppressing the RAGE/MAPK signaling pathway. Our finding highlights the potential value of timosaponin AIII as an anti-diabetic osteoporosis agent.

Abstract
Erxian decoction (EXD), a traditional Chinese medicine formula, has been used for treatment of osteoporosis for many years. The purpose of this study was to investigate the pharmacological effect of EXD in preventing osteoblast apoptosis and the underlying mechanism of prevention. Putative targets of EXD were predicted by network pharmacology, and functional and pathway enrichment analyses were also performed. Evaluations of bone mineral density, serum estradiol level, trabecular area fraction, serum calcium levels, and tumor necrosis factor (TNF)-α levels in ovariectomized rats, as well as cell proliferation assays, apoptosis assays, and western blotting in MC3T3-E1 osteoblasts were performed for further experimental validation. Ninety-three active ingredients in the EXD formula and 259 potential targets were identified. Functional and pathway enrichment analyses indicated that EXD significantly influenced the PI3K-Akt signaling pathway. In vivo experiments indicated that EXD treatment attenuated bone loss and decreased TNF-α levels in rats with osteoporosis. In vitro experiments showed that EXD treatment increased cell viability markedly and decreased levels of caspase-3 and the rate of apoptosis. It also promoted phosphorylation of Akt, nuclear translocation of transcription factor NF-erythroid 2-related factor (Nrf2), and hemeoxygenase-1 (HO-1) expression in TNF-α-induced MC3T3-E1 cells. Our results suggest that EXD exerted profound anti-osteoporosis effects, at least partially by reducing production of TNF-α and attenuating osteoblast apoptosis via Akt/Nrf2/HO-1 signaling pathway.

Abstract
The discovery of novel antimicrobials from animal species under pollution is an area untapped. Chinese red-headed centipede is one of the hardiest arthropod species commonly known for its therapeutic value in traditional Chinese medicine. Here we determined the antibacterial activity of haemolymph and tissue extracts of red-headed centipede, Scolopendra subspinipes against a panel of Gram-positive and Gram-negative bacteria. Lysates exhibited potent antibacterial activities against a broad range of bacteria tested. Chemical characterization of biologically active molecules was determined via liquid chromatography mass spectrometric analysis. From crude haemolymph extract, 12 compounds were identified including: (1) L-Homotyrosine, (2) 8-Acetoxy-4-acoren-3-one, (3) N-Undecylbenzenesulfonic acid, (4) 2-Dodecylbenzenesulfonic acid, (5) 3H-1,2-Dithiole-3-thione, (6) Acetylenedicarboxylate, (7) Albuterol, (8) Tetradecylamine, (9) Curcumenol, (10) 3-Butylidene-7-hydroxyphthalide, (11) Oleoyl Ethanolamide and (12) Docosanedioic acid. Antimicrobial activities of the identified compounds were reported against Gram-positive and Gram-negative bacteria, fungi, viruses and parasites, that possibly explain centipede's survival in harsh and polluted environments. Further research in characterization, molecular mechanism of action and in vivo testing of active molecules is needed for the development of novel antibacterials.

Abstract
Cell membrane chromatography is a promising technique for screening active components from complex matrices. Unfortunately, the large consumption of cells and low resolutions of analytes limit the applications of this method. Herein, we report polyether ether ketone tube as a novel cellular membrane carrier for cell membrane chromatography. Its inner surface is firstly coated by polyvinyl alcohol and then cell membranes are physically adsorbed onto the polyvinyl alcohol layer. To verify this approach, osteoclast and osteoblast micro-column were prepared and characterized by calcitonin and verapamil, respectively. Comparing with common cell membrane chromatographic column, the micro-cell membrane chromatographic columns showed about 1000-fold decrease of cell consumption and satisfactory retention behavior. The developed column was applied to screen potential active components from Cortex Phellodendri Chinensis. A total of 18 components in Cortex Phellodendri Chinensis extract were observed as having retention property of osteoclast micro-cell membrane chromatographic column, while 10 components retained on osteoblast micro-cell membrane chromatographic column. The results of in vitro assay showed that berberine, obacunoic acid and phellodendrine had an obvious inhibitory effect on osteoclast differentiation and function. Berberine and tetrahydropalmatine increased the osteoblast proliferations and mineralized nodules density. This cell membrane/polyvinyl alcohol column can be applied to various biological chromatography models.

Liu HJ, Liu XY, Jing DB. Icariin induces the growth, migration and osteoblastic differentiation of human periodontal ligament fibroblasts by inhibiting Toll-like receptor 4 and NF-κB p65 phosphorylation. Mol Med Rep 2018; 18:3325-3331. [PMID: 30066868 PMCID: PMC6102717 DOI: 10.3892/mmr.2018.9302] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2017] [Accepted: 06/19/2018] [Indexed: 02/07/2023] Open
Abstract
The proliferation, migration and differentiation capacities of human periodontal ligament fibroblasts (HPDLCs) are important for the treatment of periodontal diseases. The aim of the present study was to investigate whether icariin could promote these abilities in HPDLCs, and explore the cellular mechanisms therein. The results indicated that icarrin markedly blocked apoptosis, and increased the viability and migration of HPDLCs, particularly at the concentrations of 20 and 50 µM. In addition, icariin significantly promoted HPDLCs to synthesize extracellular matrix, which was reflected by the decreased expression of matrix matalloproteinase-1 and increased expression of tissue inhibitor of metalloproteinase-1. Furthermore, the levels of bone morphogenetic protein 2, collagen I, osteoprotegerin and alkaline phosphatase were markedly elevated by icariin, indicating that icariin was able to promote the osteogenic differentiation capability of HPDLCs. Icariin also inactivated the Toll-like receptor 4 (TLR)-4/nuclear factor (NF)-κB signaling pathway by suppressing the expression levels of TLR-4 and phosphorylated p65, and by blocking p65 nuclear translocation. These results suggested that icarrin increased the survival, migration and osteoblastic differentiation of HPDLCs by inhibiting the TLR-4/NF-κB signaling pathway.

Abstract
INTRODUCTION Cell membrane chromatography (CMC), as a highly selective type of affinity chromatography, has been demonstrated as an effective method to screen bioactive components acting on specific receptor from a complicated biological system. OBJECTIVE To review the recent research progress and the technical applications of these analytical methods using CMC combined with gas chromatography-mass spectrometry, (GC/MS) and liquid chromatography-mass spectrometry (LC/MS). METHODOLOGY In this review, we briefly introduce the CMC offline GC/MS, CMC online GC/MS, CMC offline LC/MS, and CMC online LC/MS system. And the practical application of these technologies is also enumerated. Then the future of these technologies and research methods were discussed. RESULTS Many bioactive components interacting with specific receptors have been screened and identified in traditional Chinese medicines. CONCLUSION CMC technique has been combined with GC/MS and HPLC/MS and these combined systems have been successfully used to screen bioactive components acting on specific receptors from a complicated biological system.
