Abstract
BACKGROUND Phillyrin, the major lignin compound of Forsythia suspense (Thunb.) Vahl, has been shown the effects of anti-inflammatory and antioxidant. Our study was aimed to explore the protective effect of phillyrin on glomerular mesangial cells (HBZY-1) and the potential mechanism. METHODS Cell viability, cytokine production, levels of reactive oxygen radicals (ROS), glutathione (GSH), malondialdehyde (MDA), and superoxide dismutase (SOD), as well as autophagy and apoptosis levels were determined to verify the mechanism of phillyrin on HBZY-1 cells. RESULTS Our result indicated that phillyrin significantly inhibited HG-induced HBZY-1 proliferation by inhibiting Bcl-2 expression and upregulating Bad, cleaved caspase-3, and -9 expression. Also, phillyrin suppressed HG-induced mesangial extracellular matrix accumulation by inhibiting the expression of fibronectin and transforming growth factor-β1. Further, phillyrin inhibited oxidative stress and inflammation by decreasing ROS, MDA, TNF-α, IL-1β, and IL-6 contents and increasing SOD and GSH expression. Phillyrin also promoted autophagy by increasing LC3-II/LC3-I ratio and down-regulating p62 expression. Furthermore, WB assay showed that phillyrin inhibited oxidative stress caused by HG via activating Nrf2 signaling pathway, while attenuated proliferation and inflammation in HBZY-1 cells through inactivating PI3K/Akt/mTOR and NF-κB pathways. CONCLUSION All results showed that phillyrin might be a promising therapeutic agent for the treatment of DN.

Abstract
OBJECTIVES Prolonged exposure to chronic hypertension places the heart under excessive strain, resulting in myocardial remodeling. Phillyrin, derived from the natural plant Forsythia suspensa, has been found to possess cardioprotective properties. The objective of this study is to investigate the role and mechanism of phillyrin in hypertension-induced myocardial remodeling in mice. METHODS We constructed a mouse model of salt-sensitive hypertension. The mice were treated with varying doses of phillyrin, and their blood pressure, cardiac function, cardiac hypertrophy, fibrosis, inflammation, and other conditions were assessed. KEY FINDINGS Our research findings demonstrated that phillyrin has the potential to lower blood pressure, enhance cardiac function, and mitigate cardiac hypertrophy, fibrosis, and inflammatory responses in deoxycorticosterone acetate-salt hypertension mice. In hypertensive mice, there was an elevated expression of endothelin1 (ET-1) in heart tissue, which can be reduced by phillyrin. Additionally, phillyrin effectively reduced the hypertrophy of H9c2 cells induced by ET-1 stimulation. CONCLUSIONS Our research highlights the therapeutic capabilities of phillyrin in the treatment of myocardial remodeling through the reduction of ET-1 signaling. These results contribute to the advancement of novel applications for phillyrin and establish a solid conceptual basis for future investigations in this area.

Abstract
Forsythia suspensa (Thunb.) has been widely used in traditional medicines in Asia. According to the 2020 edition of Chinese Pharmacopoeia, phillyrin is the main active ingredient in F. suspensa, which is effective in clearing heat, reducing swelling, and dispersing nodules. F. suspensa leaf is a non-toxic substance and it can be used to make a health tea. Here, we combine elicitors and transcriptomics to investigate the inducible biosynthesis of the phillyrin from the F. suspensa. After the fruits and leaves of F. suspensa were treated with different concentrations of methyl jasmonate (MeJA), the content of phillyrin in the fruits reached a peak at 200 µM MeJA for 12 h, but which was decreased in leaves. To analyze the differences in key enzyme genes involved in the phillyrin biosynthesis, we sequenced the transcriptome of F. suspensa leaves and fruits treated with 200 µM MeJA for 12 h. We hypothesized that nine genes related to coniferin synthesis including: F. suspensa UDP-glycosyltransferase (FsUGT); F. suspensa 4-coumarate coenzyme CoA ligase (Fs4CL); and F. suspensa Caffeoyl-CoA O-methyltransferase (FsCCoAOMT) etc. The qRT-PCR analysis of genes related to phillyrin biosynthesis was consistent with RNA-seq analysis. We also investigated the dynamic changes of genes in F. suspensa leaves and fruits at different time points after 200 µM MeJA treatment, which laid the foundation for further study of the molecular mechanisms regulating the biosynthesis of phillyrin.

The Taste-Masking Mechanism of Chitosan at the Molecular Level on Bitter Drugs of Alkaloids and Flavonoid Glycosides from Traditional Chinese Medicine. Molecules 2022; 27:7455.

Abstract
Taste masking of traditional Chinese medicines (TCMs) containing multiple bitter components remains an important challenge. In this study, berberine (BER) in alkaloids and phillyrin (PHI) in flavonoid glycosides, which are common bitter components in traditional Chinese medicines, were selected as model drugs. Chitosan (CS) was used to mask their unfriendly taste. Firstly, from the molecular level, we explained the taste-masking mechanism of CS on those two bitter components in detail. Based on those taste-masking mechanisms, the bitter taste of a mixture of BER and PHI was easily masked by CS in this work. The physicochemical characterization results showed the taste-masking compounds formed by CS with BER (named as BER/CS) and PHI (named as PHI/CS) were uneven in appearance. The drug binding efficiency of BER/CS and PHI/CS was 50.15 ± 2.63% and 67.10 ± 2.52%, respectively. The results of DSC, XRD, FTIR and molecular simulation further indicated that CS mainly masks the bitter taste by disturbing the binding site of bitter drugs and bitter receptors in the oral cavity via forming hydrogen bonds between its hydroxyl or amine groups and the nucleophilic groups of BER and PHI. The taste-masking evaluation results by the electronic tongue test confirmed the excellent taste-masking effects on alkaloids, flavonoid glycosides or a mixture of the two kinds of bitter components. The in vitro release as well as in vivo pharmacokinetic results suggested that the taste-masked compounds in this work could achieve rapid drug release in the gastric acid environment and did not influence the in vivo pharmacokinetic results of the drug. The taste-masking method in this work may have potential for the taste masking of traditional Chinese medicine compounds containing multiple bitter components.

Abstract
The function of white adipose tissue as an energy reservoir is impaired in obesity, leading to lipid spillover and ectopic lipid deposition. Adipose tissue inflammation can reduce the efficacy of lipid storage in adipocytes by augmenting basal lipolysis through producing interleukin-6 (IL-6). Therefore, pharmacological compounds targeting adipose tissue inflammation or IL-6 signaling might have the potential to combat obesity. This study aims to investigate the impact of Phillyrin, which is frequently used for treating respiratory infections in clinics in China, on obesity-related metabolic dysfunctions. Firstly, a mouse model of diet-induced obesity is used to assess the pharmacological applications of Phillyrin on obesity in vivo. Secondly, ex vivo culture of adipose tissue explants is utilized to investigate actions of Phillyrin on IL-6-linked basal lipolysis. Thirdly, a mouse model of IL-6 injection into visceral adipose tissue is explored to confirm the anti-basal lipolytic effect of Phillyrin against IL-6 in vivo. The results show that Phillyrin treatment reduces circulating level of glycerol, decreases hepatic steatosis and improves insulin sensitivity in obese mice. Meanwhile, Phillyrin attenuates obesity-related inflammation and IL-6 production in adipose tissue in obese mice. Furthermore, Phillyrin treatment results in resistance to IL-6-induced basal lipolysis in adipose tissue through suppressing expression of adipose triglyceride lipase (ATGL) both in vivo and in vitro. Collectively, these findings suggest that Phillyrin can restrain lipid efflux from inflamed adipose tissue in obesity by inhibiting IL-6-initiated basal lipolysis and ATGL expression, and thus is a potential candidate in the treatment of obesity-associated complications.

Abstract
Phillyrin is an effective lignan glycoside extracted from a traditional Chinese medicine Forsythia suspensa (Thunb.) Vahl (Oleaceae). It mainly exists in the roots, stems, leaves and fruits of the plant, with the highest content in the leaves. In terms of its medicinal application, there are a large number of experimental data proving its pharmacological effects in vitro and in animal models, such as anti-inflammatory, anti-obesity, anti-tumor, etc. Furthermore, pharmacokinetic experiments have also shown phillyrin's high effectiveness and low toxicity. Despite more than one thousand studies in the literature on phillyrin retrievable from Web of Science, PubMed, and CNKI, few reviews on its pharmacological activities have been presented conclusively. In this paper, we aimed to summarize the pharmacological and pharmacokinetic characteristics of phillyrin from the current literature, focusing on its anti-inflammatory, anti-aging, antiviral, antibacterial, hepatoprotective and anti-cancer effects, hoping to come up with new insights for its application as well as future studies.

Abstract
This study explored the role and potential molecular mechanism of phillyrin in cerebral ischemia/reperfusion (I/R) injury. The rat middle cerebral artery occlusion (MCAO)/R model was constructed, and cerebral infarction volume, brain water content, and neurological score were measured. Neuron morphological structures in brain tissues and primary neuron apoptosis were detected using hematoxylin and eosin (H&E) staining and Hoechst 33258 staining, respectively. In MCAO/R rats, phillyrin markedly reduced cerebral infarction volume, neurological score, and brain water content and inhibited neuron apoptosis. In vitro experiments showed that phillyrin remarkably increased viability and decreased lactate dehydrogenase (LDH) release of H2O2-injured neurons. Moreover, phillyrin remarkably downregulated the proportion of apoptosis-related protein B-associated X (Bax)/B-cell lymphoma protein 2 (Bcl-2) and reduced procaspase-3, phospho-Akt (p-Akt-1), and phosphorylation-mammalian target of rapamycin (p-mTOR) levels in H2O2-injured neurons. Furthermore, phosphatidylinositol-3 kinase (PI3K) inhibitor ZSTK474 weakened the effects of phillyrin on p-mTOR, p-Akt-1, characteristic proteins of autophagy 3-II (LC3-II) and beclin-1 levels, and H2O2-induced neuronal apoptosis and autophagy. Taken together, phillyrin alleviates I/R injury by inhibiting neuronal cell apoptosis and autophagy pathway, which may provide a new treatment strategy for cerebral I/R injury.

Abstract
Background: The risk of co-epidemic between COVID-19 and influenza is very high, so it is urgent to find a treatment strategy for the co-infection. Previous studies have shown that phillyrin can not only inhibit the replication of the two viruses, but also has a good anti-inflammatory effect, which is expected to become a candidate compound against COVID-19 and influenza. Objective: To explore the possibility of phillyrin as a candidate compound for the treatment of COVID-19 and influenza co-infection and to speculate its potential regulatory mechanism. Methods: We used a series of bioinformatics network pharmacology methods to understand and characterize the pharmacological targets, biological functions, and therapeutic mechanisms of phillyrin in COVID-19 and influenza co-infection and discover its therapeutic potential. Results: We revealed potential targets, biological processes, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, and upstream pathway activity of phillyrin against COVID-19 and influenza co-infection. We constructed protein-protein interaction (PPI) network and identified 50 hub genes, such as MMP9, IL-2, VEGFA, AKT, and HIF-1A. Furthermore, our findings indicated that the treatment of phillyrin for COVID-19 and influenza co-infection was associated with immune balance and regulation of hypoxia-cytokine storm, including HIF-1 signaling pathway, PI3K-Akt signaling pathway, Ras signaling pathway, and T cell receptor signaling pathway. Conclusion: For the first time, we uncovered the potential targets and biological pathways of phillyrin for COVID-19 and influenza co-infection. These findings should solve the urgent problem of co-infection of COVID-19 and influenza that the world will face in the future, but clinical drug trials are needed for verification in the future.

Abstract
Background: Phillyrin (Phi) is the main polyphenolic compound found in Forsythia suspensa. Recent studies have revealed that Phi has potent antioxidative and anti-inflammatory effects. However, whether Phi could relieve blood-brain barrier (BBB) damage following traumatic brain injury (TBI) remains unknown. Materials and Methods: Lipopolysaccharide (LPS) was used to activate primary microglia, which were then treated with different doses of Phi or the peroxisome proliferator-activated receptor-gamma (PPARγ) antagonist (GW9662). CCK-8 assay was used for evaluating cell viability, and the cytokines (including IL-1β, IL-6, TNFα, IL-4, IL-10, and TGFβ), microglial phenotypic markers (iNOS, COX2, and CD86 for "M1" polarization; Arg1, Ym1, and CD206 for "M2" polarization), PPARγ, and NF-κB were determined by RT-PCR, Western blot, or cellular immunofluorescence. Primary cultured mouse brain microvascular endothelial cells (BMECs) were stimulated by the condition medium (CM) from microglia. The cell viability, angiogenesis, and tight junction of BMECs were determined via CCK-8 assay, tube formation assay, and Western blot (for detecting MMP3, MMP9, ZO1, claudin-5, and occludin). Furthermore, the mouse TBI model was constructed and treated with Phi and/or GW9662. The BBB integrity was evaluated by H&E staining, Evans blue staining, and tissue immunofluorescence. Results: Phi markedly restrained the pro-inflammatory ("M1" state) cytokines and promoted anti-inflammatory ("M2" polarization) cytokines in LPS-mediated microglia. Phi mitigated "M1" polarization and promoted "M2" polarization of microglia via enhancing PPARγ and inhibiting the NF-κB pathway. The PPARγ antagonist GW9662 significantly repressed Phi-mediated anti-inflammatory effects. Meanwhile, Phi enhanced the viability, tube formation ability, and cell junction of BMECs. In the TBI mouse model, Phi promoted "M2" polarization, whereas it repressed the "M1" polarization of microglia. In addition, Phi reduced TBI-mediated BBB damage. However, the protective effects of Phi were reversed mainly by GW9662 treatment. Conclusion: Phi prevents BBB damage via inhibiting the neuroinflammation of microglia through the PPARγ/NF-κB pathway, which provides a potential therapeutic drug against TBI.

Abstract
The aim of this study was to identify the optimal extraction conditions for leaves of Osmanthus fragrans var. aurantiacus. Inhibitory effects of various extracts on NO production were compared. Antioxidant evaluations for total phenol and flavonoid contents were carried out using various extracts of O. fragrans var. aurantiacus leaves obtained under optimal extraction conditions that showed the greatest effect on NO production. The optimal method for extracting O. fragrans var. aurantiacus leaves resulted in an extract named OP OFLE. OP OFLE showed DPPH and ABTS radical scavenging activities in a concentration-dependent manner. Phillyrin (PH) was isolated as a major compound from OP OFLE by HPLC/DAD analysis. OP OFLE and PH reduced inducible nitric oxide (iNOS) and cyclooxygenase (COX)-2 protein expression and downregulated proinflammatory cytokines such as interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor (TNF)-α in LPS-stimulated RAW 264.7 and HT-29 cells. To determine the signal pathway involved in the inhibition of NO production, a Western blot analysis was performed. Results showed that OP OFLE decreased phosphorylation of extracellular regulated kinase (pERK) 1/2 and the expression of nuclear factor-kappa B (NF-κB). Our results suggest that extracts of O. fragrans var. aurantiacus leaves and its major components have biological activities such as antioxidative and anti-inflammatory properties.

Abstract
Forsythia fruit (Forsythia suspensa Vahl (Oleaceae)) is a common component of Kampo medicines for treating the common cold, influenza, and allergies. The main polyphenolic compounds in the leaves of F. suspensa are pinoresinol β-d-glucoside, phillyrin and forsythiaside, and their levels are higher in the leaves of the plant than in the fruit. It is known that polyphenolic compounds stimulate lipid catabolism in the liver and suppress dyslipidemia, thereby attenuating diet-induced obesity and polyphenolic anti-oxidants might attenuate obesity in animals consuming high-fat diets. Recently, phillyrin was reported as a novel cyclic AMP phosphodiesterase 4 (PDE4) inhibitor derived from forsythia fruit. It was expected that the leaves of F. suspensa might display anti-obesity effects and serve as a health food material. In this review, we summarized our studies on the biological effects of forsythia leaves containing phillyrin and other polyphenolic compounds, particularly against obesity, atopic dermatitis, and influenza A virus infection, and its potential as a phytoestrogen.

Abstract
Damage to the integrity of heparin sulfate (HS) in the endothelial glycocalyx is an important factor of glomerular filtration barrier dysfunction, which is the basic pathological feature of acute kidney injury (AKI). AKI is a common clinical critical illness with few drugs options offering effective treatment. Phillyrin (Phil), the main pharmacological component of Forsythia suspensa, possesses a wide range of pharmacological activities. However, the effects of Phil on lipopolysaccharide (LPS)-induced AKI have yet to be reported. The aim of the present study is to analyze the effects of Phil on HS damage and inflammatory signaling pathways in LPS-induced AKI. Results revealed that Phil reduces pathological changes and improves renal function in LPS-induced AKI. Further analysis indicated that Phil effectively protects against glycocalyx HS degradation in LPS-stimulated EA.hy926 cells in vitro and LPS-induced AKI mice in vivo. The protective effect of Phil on HS damage may be associated with the isolate's ability to suppress the production of reactive oxygen species, and decrease expression levels of cathepsin L and heparanase in vitro and in vivo. In addition, ELISA and Western blot results revealed that Phil inhibits the activation of the NF-κB and MAPK signaling pathways and decreases the levels of inflammatory cytokines (IL-1β, IL-6, and TNF-α) in LPS-induced ARDS mice. In general, protection against endothelial glycocalyx HS damage and inhibition of inflammatory responses by Phil may be used as treatment targets for LPS-induced AKI.

Abstract
Cardiac fibrosis (CF) greatly influences the therapeutic effects of heart diseases and remains an urgent challenge in clinical therapy. Till now, only a few methods are used to find potential anti-CF drugs effectively. This study aimed to construct a gene functional module to represent the core pathological process of CF and screen antifibrotic agents capable of decreasing the expression of the gene functional module. First, three CF marker genes Postn, Ddr2, and Pdgfra were selected to identify the corresponding highest coexpressed genes in the genome-based transcriptional profiles of human hearts. Both the marker genes and the coexpressed genes formed the CF-related gene functional module. Second, the correlation of the module with the CF process was measured in a collection of gene expression profiles of heart diseases to evaluate the participation of the functional module in heart diseases. Third, the anti-CF effects of phillyrin were predicted by the enrichment analysis of the module in the phillyrin-induced transcriptional profile. Finally, the myocardial infarction animal model was used to validate the cardioprotective and anti-CF effects of phillyrin experimentally. The results showed that phillyrin was a novel antifibrotic agent in heart diseases.

Abstract
As the sole cell type responsible for bone resorption, osteoclasts play a pivotal role in a variety of lytic bone diseases. Suppression of osteoclast formation and activation has been proposed as an effective protective therapy for new bone. In this study, we reported for the first time that phillyrin (Phil), an active ingredient extracted from forsythia, significantly inhibited RANKL-induced osteoclastogenesis and bone resorption in vitro and protected against lipopolysaccharide-induced osteolysis in vivo. Further molecular investigations demonstrated that Phil effectively blocked RANKL-induced activations of c-Jun N-terminal kinase and extracellular signal-regulated kinase, which suppressed the expression of c-Fos and nuclear factor of activated T-cells cytoplasmic 1. Taken together, these data suggested that Phil might be a potential antiosteoclastogenesis agent for treating osteoclast-related bone lytic diseases.

Abstract
In the present study, we evaluated the antibacterial and anti-quorum sensing qualities of phillyrin. The minimum inhibitory concentration (MIC) of phillyrin with regard to
Pseudomonas aeruginosa is 0.5 mg/ml. The production of virulence factors—such as rhamnolipid (>78.69%), pyocyanin (>85.94%), and elastase
(>89.95%)—that affect the pathogenicity of the P. aeruginosa strain PAO1 apparently declined in the presence of 0.25 mg/ml phillyrin. Biofilm formation
decreased by 84.48%. In a Caenorhabditis elegans–Pseudomonas aeruginosa infection model, diseased worms lived longer (63.33%) in a phillyrin-containing medium than in a
drug-free medium, and the drug did not directly kill the pathogen. Therefore, the present work suggests that phillyrin has potential as an antimicrobial agent for the control of infectious
pathogens.
