[PMID: 38754799 DOI: 10.1016/j.phytochem.2024.114144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 05/13/2024] [Accepted: 05/14/2024] [Indexed: 05/18/2024]
Abstract
Nine previously undescribed iridoids, ptehosides A-I (1-9), together with 12 known ones (10-21), were isolated from Pterocephalus hookeri (C.B. Clarke) Höeck. Their structures were elucidated using various spectroscopic methods including HR-ESI-MS, NMR, UV, IR and CD, etc. The cytotoxic activities of all isolates were evaluated using MTT method in three human cancer cell lines (Caco2, Huh-7, and SW982). As result, compound 9 exhibited substantial inhibitory activity on Caco2, Huh-7, and SW982 cells with IC50 values of 1.17 ± 0.05, 1.15 ± 0.05 and 1.14 ± 0.04 μM, respectively. A preliminary mechanism study showed that 9 arrested the cell cycle of SW982 cells in the G0/G1 phase and induced apoptosis by upregulating Bax expression and downregulating Bcl-2 expression.

Abstract
Pterocephali Herba (PH), the dried whole plant of Pterocephalus hookeri, is a Tibetan medicine commonly used to treat rheumatoid arthritis (RA). Iridoids, triterpenoids, flavonoids and phenylpropanoids are the major groups of bioactive constituents from PH. However, only ursolic acid and oleanolic acid, two unspecific triterpenoid components, are used as markers for the quality control of PH in Chinese Pharmacopoeia. Herein, an UPLC-TQ-MS/MS integrating SIR and MRM mode method for simultaneously quantifying 18 components, i.e., 9 iridoids, 3 triterpenoids, 3 phenylpropanoids, 2 flavonoids and quinic acid, in PH was developed and validated, and was used to evaluate 10 batches of PH samples from different origins. Hierarchical cluster analysis (HCA) was used to show the clustering of PH samples, while spearman correlation analysis was adopted to evaluate the correlation between ursolic acid/oleanolic acid and other quantified components. It was found that the established method was sensitive, precise, and accurate enough for the simultaneous quantification of 18 analytes in PH samples. Significant differences were found among the contents of 18 components in PH samples, no apparent clustering of the quality of PH samples was found to be related to its origins, and the contents of ursolic acid/oleanolic acid were only significantly correlated to the content of sylvestroside I, dipsanoside B, dipsanoside A in PH. Our results suggested that the newly established multi-components quantitative method is an improved approach for quality evaluation of PH samples. Furthermore, the holistic quality was inconsistent among PH samples, and ursolic acid/oleanolic acid alone could not indicate the holistic quality variation trend of PH.

'Pterocephalodes hookeri-Onosma hookeri' decoction protects against LPS-induced pulmonary inflammation via inhibiting TLR4/ NF-κB signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116918. [PMID: 37453619 DOI: 10.1016/j.jep.2023.116918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/11/2023] [Accepted: 07/12/2023] [Indexed: 07/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As the second-largest traditional medical system in China, Tibetan medicine has a long history and abundant resources. To promote the development of the Tibetan medicine industry, it is essential to study the pharmacological activities of Tibetan medicine based on its traditional usage methods. AIM OF THE STUDY Pneumonia has been a worldwide health problem with high morbidity and mortality rates, especially in the context of the COVID-19 epidemic. Given the unique advantages of traditional Tibetan medicine in treating pulmonary diseases, further research is warranted to develop potential anti-pneumonia drugs. MATERIALS AND METHODS In our study, the potential combined decoction from traditional Tibetan medicine was determined by the data mining method. The antioxidant activity in vitro, anti-inflammatory effects on the macrophage cell model, as well as the anti-pulmonary inflammation effects on the LPS-induced mice model, have been explored to investigate the potential anti-pneumonia role of the decoction. Additionally, we conducted network pharmacology analysis to identify the potential targets against pneumonia, which were further confirmed by western blot assays. RESULTS Following the combination therapy of Pterocephalodes hookeri (C.B.Clarke) V.Mayer & Ehrend. and Onosma hookeri var. longiflora (Duthie) A.V.Duthie ex Stapf ('P-O'), the clearance of DPPH radical and the total reducing power were all improved, as well as alleviated the toxicity. On the in vitro level, 'P-O' pre-treatment reduced the secretion of NO, TNF-α, IL-6, and IL-1β in LPS-stimulated RAW264.7 cells, while promoting the concentration of IL-10. Meanwhile, on the in vivo level, the 'P-O' pre-treating also could alleviate LPS-induced pulmonary inflammation by reducing the pulmonary edema and leakage of the lung microvascular, improving the pathological change of lung tissue and regulating the cytokines content in bronchoalveolar lavage fluid (BALF). Furthermore, network pharmacology analysis revealed that the mechanism of 'P-O' in treating pneumonia in a multi-component, multi-target, and multi-pathway network, with the TLR4/NF-κB signaling pathway playing a crucial role, as demonstrated by the western blot assay results. CONCLUSION In summary, the combination therapy of 'P-O' exhibited good antioxidant activity and anti-inflammatory activity in vitro, as well as a therapeutic effect against pulmonary inflammation in vivo. These findings provide evidence for the clinical application of 'P-O' and offer new approaches for treating pneumonia.

Abstract
Rheumatoid arthritis (RA) is a severe inflammatory autoimmune disease characterized by the failed spontaneous resolution of inflammation. The induction of immune regulation and resolution of inflammatory pathways are effective in alleviating inflammation in RA. As the oldest medical system in the world, traditional Tibetan medicine (TTM) has a long history of preventing and treating RA. This review provides a comprehensive overview of medicinal plants with anti-RA activity in the TTM system, using classic books of Tibetan medicine, modern research literature, and drug standards. A total of 27 species have been found to be effective in treating RA, including Tinospora sinensis (Lour.) Merr., Terminalia chehula Retz., P. hookeri (C. B. Clarke) Hock.), and Aconitum pendulum Busch. Alkaloids, flavonoids, polyphenols, and terpenoids have turned out to be the major bioactive components for RA treatment. The inhibition of pro-inflammatory cytokine expression by mediating the NF-κB, MAPK, and JAK/STAT pathways is the core mechanism in RA treatment. In conclusion, this review provides key information and research perspectives for further research on the anti-RA effects of TTM.

Abstract
Four new secoiridoid-iridoid heterodimers, pterocenoids E -H ( 1 - 4 ), together with a known analogue ( 5 ), were separated from the whole plants of Pterocephalus hookeri . Their structures were characterized by detailed spectroscopic analyses and NMR comparison with reported data for known analogues. Pterocenoid E ( 1 ) represents the first bis-iridoid example incorporating a rare trans -fused monomeric unit , and the C(8) configuration in 5 was corrected to be reversed to the original assignment. Among all the isolates, compound 5 not only showed moderate inhibition against the nitric oxide production (IC 50 = 36.0 ± 4.3 mM ) but also dose-dependently suppressed the secretion of an important pro-inflammatory cytokine TNF-a, in lipopolysaccharide-induced RAW264.7 cells.

Abstract
Lyme disease (LD) is a tick-borne bacterial disease that is caused by Borrelia burgdorferi. Although acute LD is treated with antibiotics, it can develop into relapsing chronic form caused by latent forms of B. burgdorferi. This leads to the search for phytochemicals against resistant LD. Therefore, this study aimed to evaluate the activity of Dipsacus fullonum L. leaves extract (DE) and its fractions against stationary phase B. burgdorferi in vitro. DE showed high activity against stationary phase B. burgdorferi (residual viability 19.8 ± 4.7%); however, it exhibited a noticeable cytotoxicity on NIH cells (viability 20.2 ± 5.2%). The iridoid-glycoside fraction showed a remarkable anti-Borrelia effect and reduced cytotoxicity. The iridoid-glycoside fraction was, therefore, further purified and showed to contain two main bioactives—sylvestrosides III and IV, that showed a considerable anti-Borrelia activity being the least toxic to murine fibroblast NIH/3T3 cells. Moreover, the concentration of sylvestrosides was about 15% of DE, endorsing the feasibility of purification of the compounds from D. fullonum L. leaves.

Targeted Separation of COX-2 Inhibitor from Pterocephalus hookeri Using Preparative High-Performance Liquid Chromatography Directed by the Affinity Solid-Phase Extraction HPLC System. Molecules 2021; 26:molecules26237395.

Abstract
Pterocephalus hookeri, as a kind of popular traditional Tibetan medicine, is reputed to treat inflammatory related diseases. In the present work, a cyclooxygenase-2 functionalized affinity solid-phase extraction HPLC system was developed and combined with preparative-HPLC for rapidly screening and separating cyclooxygenase-2 ligand from P. hookeri extracts. Firstly, ligands of cyclooxygenase-2 were screened from extracts by affinity solid-phase extraction HPLC system. Then directed by the screening results, the recognized potential active compounds were targeted separated. As a result, the major cyclooxygenase-2 inhibitor of P. hookeri was obtained with a purity of >95%, which was identified as sylvestroside I. To test the accuracy of this method, the anti-inflammatory activity of sylvestroside I was inspected in lipopolysaccharide-induced RAW 264.7 cells. The results show that sylvestroside I significantly suppressed the release of prostaglandin E2 with dose-dependent, which was in good agreement with the screening result of the affinity solid-phase method. This method of integration of screening and targeted separation proved to be very efficient for the recognition and isolation of cyclooxygenase-2 inhibitors from natural products.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lantana canescens is popularly known in Brazil as "cidreirinha" or "chumbinho-branco". It is found in Pantanal biome and its flowers and leaves are used in traditional medicine to treat pain and inflammation. Information about this species is limited to the activity of isolated essential oils. Studies with different extracts, composition, and biological properties are still scarce. AIM OF THIS STUDY The objective of this study was to evaluate the anti-inflammatory and anti-hyperalgesic activity of the hydroethanolic extract of L. canescens aerial parts. MATERIALS AND METHODS The hydroethanolic extract L. canescens aerial parts (HELc) was analyzed using HPLC-DAD-EM. Male and female Swiss mice weighing 18-25 g were used in the in vivo assays. Acute toxicity was assessed (2000 mg/kg); anti-inflammatory activity through paw edema, mast cell degranulation and peritonitis, and anti-hyperalgesic activity through abdominal writhing assays induced by acetic acid and formalin sensitization, were evaluated using the doses of 3, 30 and 300 mg/kg. RESULTS The phytochemical characterization of HELc confirmed the presence of glycosylated iridoids (theveside, theviridoside), verbascosides and flavonoids. The HELc did not present toxicity in the evaluated dose. HELc reduced formation of paw edema, degranulation of peritoneal mast cells and infiltration of polymorphonuclear cells into the animals peritoneal cavity. In addition, HELc decreased the number of abdominal writhing induced by acetic acid and the time of paw licking in the evaluation of formalin sensitization. CONCLUSIONS These results confirm the anti-inflammatory and anti-hyperalgesic effects of hydroethanolic extract of L. canescens, validating the use of this plant in folk medicine.

Abstract
Pterocephalus hookeri, a classical Tibetan herb, is mainly used to treat rheumatoid arthritis (RA) and contains various constituents potentially with cyclooxygenase-2 (COX-2) selective inhibition. A novel strategy for screening and target separating COX-2 inhibitors from the extracts of P. hookeri based on affinity solid-phase extraction (ASPE) column combined with preparative high-performance liquid chromatography (pre-HPLC) was successfully developed. The potential COX-2 inhibitors of P. hookeri were screened and recognized by the ASPE-HPLC system, which strategy is to analyze the compounds isolated by the ASPE column. Then, the active compounds were targeted separated by pre-HPLC according to real-time chromatograms. The control drugs celecoxib and glipizide were analyzed to verify the specificity and accuracy of the developed method. As a result, two pure compounds with COX-2 binding affinities were successfully separated from P. hookeri. They were characterized as swertisin and scopoletin using 1H- and 13C NMR spectroscopy, and the in vitro COX-2 inhibitory activities were verified. Compounds with COX-2 inhibitory activities could be screened and targeted separated from crude extracts by this strategy, which indicated that the proposed method was feasible, robust and effective for rapid separation of COX-2 inhibitors from natural products.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 85:153548. [PMID: 33831690 DOI: 10.1016/j.phymed.2021.153548] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 01/30/2021] [Accepted: 03/12/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Pterocephalus hookeri (C. B. Clarke) Höeck, a Tibetan medicine widely used for treatment of rheumatoid arthritis, was recorded in Chinese Pharmacopoeia (2020 version) with slight toxicity. The liver injury was observed in mice with administration of n-butanol extract (BUE) in our previously study. However, the toxic components and the mechanism were still unrevealed. PURPOSE The present study was aimed to isolate and structural elucidate of the toxic compound pterocephin A (PA), as well as evaluate its liver toxicity and investigate its mechanism. METHODS PA was isolated from the BUE of P. hookeri. Its structure was determined by analysis of HRMS, NMR and ECD data. L-02 cellular viability, LDH, ALT, AST, ROS, intracellular Ca2+ and the fluidity of cell membrane were assessed by multifunctional microplate reader. The PI staining, cell membrane permeability assessment, and mitochondrial fluorescence staining analysis were determined through the fluorescence microscope. Liver samples for mice were assessed by pathological and immunohistochemistry analysis. Expression levels of indicated proteins were measured by western blotting assays. RESULTS PA was determined as a previously undescribed oleanolane-type triterpenoid saponin. In vitro study revealed PA significantly induced hepatotoxicity by inhibition of L-02 cell growth, abnormally elevation of ALT and AST. Mechanically, PA induced the damage of cell membrane, fragmentation of mitochondria, and subsequently increase of intracellular Ca2+ and ROS levels, which trigged by necroptosis with the activation of RIP1 and NF-κB signaling pathways. In vivo study confirmed PA could induce liver injury in mice with observation of the body weight loss, increasing of serum ALT and AST, and the histopathological changes in liver tissues. CONCLUSION Our present study indicated that PA was an undescribed toxic constituent in P. hookeri to induce liver injury in mice by activation of necroptosis and inflammation. And the findings are of great significance for the clinical use safely of this herb.

Abstract
Pterocephalus hookeri (C. B. Clarke) Höeck is a member of the Dipsacaceae family and has been used in traditional Tibetan medicine for thousands of years. P. hookeri clears heat, detoxifies, stops dysentery, eliminates distemper, dispels wind, and relieves stagnation and is mainly prescribed for heat syndrome, dysentery, arthritis, and plague. Approximately 93 chemical compounds have been isolated and identified from P. hookeri, including iridoid glycosides, lignan and triterpenoids. Meanwhile, modern pharmacological studies have shown that P. hookeri has anti-inflammatory, anti-rheumatoid arthritis, analgesic, anticancer, and neuroprotection activities. However, studies on the in vivo pharmacokinetics and mechanism of action, discovery of quality markers, and qualitative and quantitative analysis are still insufficient. Hence, this paper provides a comprehensive review of the ethnic medicine, phytochemistry, pharmacology, and toxicology of P. hookeri to increase the understanding of the medicinal value of P. hookeri. Pterocephalus hookeri (C. B. Clarke) Höeck has been used in traditional Tibetan medicine for thousands of years. The existing research results of P. hookeri are summarized, and will provide a basis for the further development of new drugs.![]()

Abstract
The Chinese herbal medicine, Huzhen Tongfeng Formula (HZTF), derived from traditional Chinese medicine (TCM) practice, has recognized therapeutic benefits for gouty arthritis (GA). HZTF is currently in the late stage of approval process as a new anti-GA drug application. However, the underlying mechanism of HZTF as an antigout medication is unclear. In this study, we combined network pharmacology and experimental validation approaches to elucidate the mechanism of action of HZTF. First, the relative drug-disease target networks were constructed and analyzed for pathway enrichment. Potential pathways were then validated by in vitro and in vivo experiments. We found that 34 compounds from HZTF matched 181 potential drug targets. Topology analysis revealed 77 core targets of HZTF, which were highly related to gout, following screening of KEGG pathway enrichment. Further analysis demonstrated that the arachidonic acid metabolic pathway was the most relevant pathway involved in the mechanism of HZTF. Validation experiments showed that HZTF significantly inhibited the inflammatory cell infiltration into gouty joints, improved the swelling of affected joints, and increased the pain threshold. HZTF significantly reduced the transcription and production of various cytokines and inflammatory mediators in vitro. In particular, cyclooxygenase (COX)-1, COX-2, and 5-lipoxygenase were simultaneously downregulated. In conclusion, our study suggests that the antigout mechanism of HZTF is associated with the inhibition of the arachidonic acid pathway, resulting in the suppression of inflammatory cytokines and mediators. These findings extend our understanding of the pharmacological action of HZTF, rationalizing the application HZTF as an effective herbal therapy for GA.

Abstract
Iridoids are a class of active compounds that widely exist in the plant kingdom. In recent years, with advances in phytochemical research, many compounds with novel structure and outstanding activity have been identified. Iridoid compounds have been confirmed to mainly exist as the prototype and aglycone and Ι and II metabolites, by biological transformation. These metabolites have been shown to have neuroprotective, hepatoprotective, anti-inflammatory, antitumor, hypoglycemic, and hypolipidemic activities. This review summarizes the new structures and activities of iridoids identified locally and globally, and explains their pharmacokinetics from the aspects of absorption, distribution, metabolism, and excretion according to the differences in their structures, thus providing a theoretical basis for further rational development and utilization of iridoids and their metabolites.

Abstract
Glucocorticoids have been confirmed to be effective in the treatment of a variety of inflammatory diseases. However, their application encounters limitations in terms of tissue distribution and bioavailability in vivo. To address these key issues, we designed and developed a nanopreparation by using egg yolk lecithin/sodium glycocholate (EYL/SGC) and utilize such mixed micelles (MMs) to encapsulate dexamethasone palmitate (DMP) for the treatment of rheumatoid arthritis (RA). The prepared DMP-MMs had an average particle size of 49.18 ± 0.43 nm and were compared with an emulsion-based dexamethasone palmitate. Pharmacokinetic and in vivo fluorescence imaging showed that mixed micelles had higher bioavailability and targeting efficiency in inflammatory sites. An arthritis rat model was established via induction by Complete Freund's Adjuvant (CFA), followed by the efficacy studies by the observations of paw volume, histology, spleen index, pro-inflammatory cytokines, and CT images. It was confirmed that intravenous injection of DMP-MMs exhibited advantages in alleviating joint inflammation compared with the emulsion system. Composed of pharmaceutical adjuvants only, the nanoscale mixed micelles seem a promising carrier system for the RA treatment with lipophilic drugs.

Abstract
Pterocephalus hookeri was used as a traditional Chinese medicine for the treatment of rheumatoid arthritis. Sweroside was a main iridoid isolated from P. hookeri. The present study aimed to investigate the anti-inflammatory effect mechanism of sweroside. In RAW264.7 cells induced by lipopolysaccharide (LPS), the abnormal proliferation, the NO content increase, and the downregulated Sirtuin1 (SIRT1) expression were observed. Sweroside could alleviate the inflammation by inhibiting cell proliferation through arresting the cell cycle at the G0/G1 phase, by suppressing pro-inflammatory cytokines and by promoting anti-inflammatory cytokines in LPS-induced RAW264.7 cells. Further mechanism research indicated that sweroside could activate the SIRT1, then suppress the nuclear factor-kappa B (NF-κB) and promote the Forkhead transcription factor O1 (FOXO1) signaling pathways. The present study indicated that sweroside may be the main anti-inflammatory constituent of P. hookeri and a promising candidate for anti-inflammation therapy.

Abstract
Around 70-80% of drugs used in traditional Tibetan medicine (TTM) come from Qinghai Tibet Plateau, the majority of which are plants. The biological and medicinal culture diversity on Qinghai Tibet Plateau are amazing and constitute a less tapped resource for innovative drug research and development. Meanwhile, the problem of the exhausting Tibetan medicine resources is worrying. Here, the latest awareness, as well as the gaps of the traditional Tibetan medicinal plant issues in drug development and clinical usage of TTM compounds, was systematically reviewed and highlighted. The TTM resource studies should be enhanced within the context of deeper and more extensive investigations of molecular biology and genomics of TTM plants, phytometabolites and metabolomics and ethnopharmacology-based bioactivity, thus enabling the sustainable conservation and exploitation of Tibetan medicinal resource.

Abstract
The genus Scabiosa (family Caprifoliaceae) is considered large (618 scientific plant names of species) although only 62 have accepted Latin binominal names. The majority of the Scabiosa species are widely distributed in the Mediterranean region and some Scabiosa species are used in traditional medicine systems. For instance, Scabiosa columbaria L. is used traditionally against diphtheria while S. comosa Fisch. Ex Roem. and Schult. is used in Mongolian and Tibetan traditional medical settings to treat liver diseases. The richness of Scabiosa species in secondary metabolites such as iridoids, flavonoids and pentacyclic triterpenoids may contribute to its use in folk medicine. Details on the most recent and relevant pharmacological in vivo studies on the bioactive secondary metabolites isolated from Scabiosa species will be summarized and thoroughly discussed.
