Abstract
The herb Sophora flavescens displays anti-inflammatory activity and can provide a source of antipsoriatic medications. We aimed to evaluate whether S. flavescens extracts and compounds can relieve psoriasiform inflammation. The ability of flavonoids (maackiain, sophoraflavanone G, leachianone A) and alkaloids (matrine, oxymatrine) isolated from S. flavescens to inhibit production of cytokine/chemokines was examined in keratinocytes and macrophages. Physicochemical properties and skin absorption were determined by in silico molecular modeling and the in vitro permeation test (IVPT) to establish the structure-permeation relationship (SPR). The ethyl acetate extract exhibited higher inhibition of interleukin (IL)-6, IL-8, and CXCL1 production in tumor necrosis factor-α-stimulated keratinocytes compared to the ethanol and water extracts. The flavonoids demonstrated higher cytokine/chemokine inhibition than alkaloids, with the prenylated flavanones (sophoraflavanone G, leachianone A) led to the highest suppression. Flavonoids exerted anti-inflammatory effects via the extracellular signal-regulated kinase, p38, activator protein-1, and nuclear factor-κB signaling pathways. In the IVPT, prenylation of the flavanone skeleton significantly promoted skin absorption from 0.01 to 0.22 nmol/mg (sophoraflavanone G vs. eriodictyol). Further methoxylation of a prenylated flavanone (leachianone A) elevated skin absorption to 2.65 nmol/mg. Topical leachianone A reduced the epidermal thickness in IMQ-treated mice by 47%, and inhibited cutaneous scaling and cytokine/chemokine overexpression at comparable levels to a commercial betamethasone product. Thus, prenylation and methoxylation of S. flavescens flavanones may enable the design of novel antipsoriatic agents.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sophora flavescens Ait.-Angelica sinensis(Oliv.) Diels drug pairing (SA) is a transformed drug pairing from Shengui pill, a traditional Chinese medicine prescription in the ninth volume of Traditional Chinese Medicine classic "Gu Jin Yi Jian", which is famous for clearing heat, moistening dryness, and promoting blood circulation. It is commonly used in the treatment of eczema, a skin condition that causes itching and inflammation. Despite its widespread use, there is still limited research on the mechanism of how SA treats eczema. This paper aims to fill this gap by conducting animal experiments to uncover the mechanism behind SA's therapeutic effects on eczema. Our findings provide a solid foundation for the clinical use of this TCM prescription. AIM OF THE STUDY The basic purpose of this study is to clarify the therapeutic mechanism of Sophora flavescens-Angelica sinensis (SA) in the treatment and control of eczema. MATERIALS AND METHODS The chemical compositions of SA were analyzed using HPLC-Q-Orbitrap-MS. In vivo, a mouse model of eczema was created, and the serum levels of TNF-α and IL-1β were quantified using an enzyme-linked immunosorbent assay (ELISA). Hematoxylin and eosin (HE) staining was performed to assess the pathological state of the mouse skin, and immunohistochemical technique (IHC) was employed to estimate the contents of TNF-α, TLR4, and NF-κB semi-quantitatively. The expression levels of TLR4, MyD88, and NF-κB mRNA were determined through real-time quantitative polymerase chain reaction (qRT-PCR). Western Blotting was utilized to identify the protein levels of TLR4, MyD88, and NF-κB in mouse skin tissue. RESULTS SA identified 18 active chemicals, some of which were shown in vivo to inhibit the TLR4/MyD88/NF-κB signaling pathway while reducing serum levels of TNF-α and IL-1β, making them ideal agents for the treatment of eczema. CONCLUSIONS SA's anti-inflammatory properties are attributed to its ability to reduce serum levels of TNF-α and IL-1β, likewise inhibit the TLR4/MyD88/NF-κB signaling pathway.

Abstract
Active ingredient of Sophora flavescens is reported to promote non-rapid eye movement (NREM) sleep. However, the role of Sophora flavescens alcohol extract in insomnia is elusive, which is addressed in this study, together with the exploration on its potential mechanism. An insomnia model of rats was established by para-chlorophenylalanine induction and further treated with SFAE or Zaoren Anshen capsule (ZRAS; positive control drug). Sleep quality and sleep architecture of rats were evaluated by the sleep test, electroencephalogram and electromyogram. The levels of monoamine neurotransmitters in rat hypothalamus were determined using ELISA, and the transduction of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/brain-derived neurotrophic factor (BDNF) signaling in the brain tissues of rats was examined by Western blot. SFAE and ZRAS increased the sleeping time and decreased the sleep latency of insomnia rats. SFAE reduced waking time and increased NREM and REM time, while changing power density of wakefulness, NREM sleep, and REM sleep in insomnia rats. SFAE and ZRAS upregulated levels of 5-hydroxytryptamine and 5-hydroxyindoleacetic acid, and downregulated those of norepinephrine and dopamine in insomnia rats. Besides, SFAE and ZRAS elevated BDNF expression as well as the ratios of phosphorylated (p)-PI3K/PI3K and p-AKT/AKT. The role of SFAE in insomnia model rats was similar with that of ZRAS. SFAE reduces insomnia and enhances the PI3K/AKT/BDNF signaling transduction in insomnia model rats, which can function as a drug candidate for insomnia.

Abstract
Sophora flavescens is a medicinal herb distributed widely in Japan and it has been used to treat various diseases and symptoms. To explore its pharmacological use, we examined the estrogenic activity of four prenylated flavonoids, namely kurarinone, kushenols A and I, and sophoraflavanone G, which are characterized by the lavandulyl group at position 8 of ring A, but have variations in the hydroxyl group at positions 3 (ring C), 5 (ring A) and 4' (ring B). These prenylated flavonoids were examined via cell proliferation assays using sulforhodamine B, Western blotting, and RT-PCR, corresponding to cell, protein, and transcription assays, respectively, based on estrogen action mechanisms. All the assays employed here found weak but clear estrogenic activities for the prenylated flavonoids examined. Furthermore, the activities were inhibited by an estrogen receptor antagonist, suggesting that the activities were likely being mediated by the estrogen receptors. However, there were differences in the activity, attributable to the hydroxyl group at position 4', which is absent in kushenol A. While the estrogenic activity of kurarinone and sophoraflavanone G has been reported before, to the best of our knowledge, there are no such reports on kushenols A and I. Therefore, this study represents the first report of their estrogenic activity.

Abstract
Sophora flavescens belongs to Sophora genus of Leguminosae. Its roots are used as a traditional Chinese medicine. In our study on Sophora flavescens roots, 3 new and 19 known alkaloids have been found, including 8 aloperine-type and 14 matrine-type alkaloids. The planar configurations of these compounds were determined by the spectral data, and the absolute configurations of new compounds 1, 2 and 4 were determined by pyridine solvent effect, ECD and snatzke methods, respectively. All compounds were tested for their inhibitory activity on MCF-7 cell growth, and compound 12 exhibited certain inhibitory effects on the growth of MCF-7 cells after 24 h of treatment at a concentration of 20 μM, with inhibition rates of 31.28%. Through target screening and molecular docking, human Rho GTPase activating protein 5 variant and human arachidonate 12-lipoxygenase (12S-type) might be important targets for compound 12 to exert anti-tumor activity.

Abstract
Streptococcosis disease caused by Streptococcus agalactiae (Group B Streptococcus, GBS) results in a huge economic loss of tilapia culture. It is urgent to find new antimicrobial agents against streptococcosis. In this study, 20 medicinal plants were evaluated in vitro and in vivo to obtain medicinal plants and potential bioactive compounds against GBS infection. The results showed that the ethanol extracts of 20 medicinal plants had low or no antibacterial properties in vitro, with a minimal inhibitory concentration ≥256 mg/L. Interestingly, in vivo tests showed that 7 medicinal plants could significantly inhibit GBS infection in tilapia, and Sophora flavescens (SF) had the strongest anti-GBS activity in tilapia, reaching 92.68%. SF could significantly reduce the bacterial loads of GBS in different tissues (liver, spleen and brain) of tilapia after treated with different tested concentrations (12.5, 25.0, 50.0 and 100.0 mg/kg) for 24 h. Moreover, 50 mg/kg SF could significantly improve the survival rate of GBS-infected tilapia by inhibiting GBS replication. Furthermore, the expression of antioxidant gene cat, immune-related gene c-type lysozyme and anti-inflammatory cytokine il-10 in liver tissue of GBS-infected tilapia significantly increased after treated with SF for 24 h. Meanwhile, SF significantly reduced the expression of immune-related gene myd88 and pro-inflammatory cytokines il-8 and il-1β in liver tissue of GBS-infected tilapia. The negative and positive models of UPLC-QE-MS, respectively, identified 27 and 57 components of SF. The major components of SF extract in the negative model were α, α-trehalose, DL-malic acid, D- (-)-fructose and xanthohumol, while in the positive model were oxymatrine, formononetin, (-)-maackiain and xanthohumol. Interestingly, oxymatrine and xanthohumol could significantly inhibit GBS infection in tilapia. Taken together, these results suggest that SF can inhibit GBS infection in tilapia, and it has potential for the development of anti-GBS agents.

Abstract
Matrine is an active ingredient in traditional Chinese medicine that has been shown to be effective in treating bone disorders. The anti-osteoarthritis (OA) effects of matrine were assessed using both in in vitro and in vivo systems, and the mechanisms underlying the effects were investigated by focusing on the activity of miR-29b-3p/PGRN axis. The miR was chosen as potential target for matrine after chondrocytes were treated with both IL-1? and matrine. Changes in cell viability, cell apoptosis, inflammation, and miR-29b-3p/PGRN axis were detected. In vitro assays results were validated using collagen-induced arthritis (CIA) rat models. Incubation with IL-1? reduced cell viability, induced cell apoptosis, and inhibited production of cytokines in chondrocytes, which was associated with the up-regulation of miR-29b-3p and down-regulation of PGRN. In CIA rats, matrine reduced bone destruction and weight loss in a dose-dependent manner. Matrine also reduced the systemic levels of cytokines. At the molecular level, matrine inhibited the expression of miR-29b-3p while increasing the expression of PGRN. The findings outlined in the current study showed that matrine exerted its anti-OA effects by modulating the miR-29b-3p/PGRN axis.

Abstract
The genus Sophora (Fabaceae) includes medicinal plants that have been used in East Asian countries since antiquity. Sophora flavescens is a perennial herb indigenous to China, India, Japan, Korea, and Russia. Its dried roots have antioxidant, anti-inflammatory, antibacterial, apoptosis-modulating, and antitumor efficacy. The congeneric S. koreensis is endemic to Korea and its genome is less than half the size of that of S. flavescens. Nevertheless, this discrepancy can be used to assemble and validate the S. flavescens genome. A comparative genomic study of the two genomes can disclose the recent evolutionary divergence of the polymorphic phenotypic profiles of these species. Here, we used the PacBio sequencing platform to sequence and assemble the S. koreensis and S. flavescens genomes. We inferred that it was mainly small-scale duplication that occurred in S. flavescens. A KEGG analysis revealed pathways that might regulate the pharmacologically important secondary metabolites in S. flavescens and S. koreensis. The genome assemblies of Sophora spp. could be used in comparative genomics and data mining for various plant natural products.

Abstract
The objective was to investigate the potential cardiac arrhythmia-related target proteins and molecular mechanisms underlying the anti-arrhythmic effects of Sophora flavescens using network pharmacology and molecular docking. The bioactive ingredients and related target proteins of S flavescens obtained from the Traditional Chinese medicine systems pharmacology data platform, and gene names for target proteins were obtained from the UniProt database. Arrhythmia-related genes were identified by screening GeneCards and Online Mendelian inheritance in man databases. A Venn diagram was used to identify the key arrhythmia-related genes that are potentially targeted by the bioactive ingredients of S flavescens. Furthermore, CytoScape 3.7.2 software was used to construct an "ingredient-target" network diagram and the "drug-ingredient-target-disease" network diagram. We performed gene ontology and Kyoto encyclopedia of genes and genomes enrichment analysis in the Metascape database and performed the docking analysis using CB-Dock software. We identified 45 main bioactive ingredients, from S flavescens and 66 arrhythmia-related target proteins. Gene ontology and Kyoto encyclopedia of genes and genomes pathway enrichment analysis showed that these targets were related to the chemical carcinogenesis-receptor activation signaling pathway, lipid and atherosclerosis signaling pathway, and fluid shear stress and atherosclerosis signaling pathway. Molecular docking showed that the target protein had good binding power with the main active components of the compound of S flavescens. Our study demonstrated the synergistic effects of multiple bioactive components of S flavescens on multiple arrhythmia-related target proteins and identified potential therapeutic mechanisms underlying the anti-arrhythmic effects of S flavescens, providing new clinical ideas for arrhythmia treatment.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Sophora flavescens Aiton, was a crucial source of Traditional Chinese Medicine (TCM) that has benefited human health for hundreds of years. Alkaloids and flavonoids were the major bioactive constituents from S. flavescens, which had been widely used for liver disease treatment in China. However, the liver-protective components of flavonoids from S. flavescens and their mechanism of action were not clear. AIM OF THE STUDY This work aimed to evaluate the in vitro hepatoprotective activities of 35 flavonoids from S. flavescens and screen active compounds. Furthermore, it was conducted to demonstrate the hepatoprotective effects of a new active compound (kurarinol A, 1) was isolated by authors and the ethyl acetate (EtOAc) extract form S. flavescens against carbon tetrachloride (CCl4)-induced hepatic injury in Kunming (KM) mice, meanwhile revealed the potential mechanism. MATERIALS AND METHODS The 35 flavonoids from S. flavescens were co-incubated with HepG2 cells and treated with 0.35% CCl4 for 6 h cell viability was measured by (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt) (MTS) assay. Then, in vivo animal experiments, the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in the serum were analyzed, the degree of hepatic injury was examined using hematoxylin-eosin (H&E) staining, the mRNA expression of Superoxide Dismutase 2 (SOD2), Nuclear factor E2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), Interleukin 6 (IL-6), Tumor Necrosis Factor-α (TNF-α), interleukin-1β (IL-1β), and the protein levels of nuclear factor-kappa B p65/p-p65 (NF-κB p65/p-p65), toll-like receptor 2 (TLR2), IL-1β and cyclooxygenase-2 (COX2) in hepatic tissues were detected. RESULTS The lavandulyl flavonoid (kurarinol A, 1) and the EtOAc extract from S. flavescens showed protective effects on CCl4-injured HepG2 cells, increasing cell viability from 24.5% to 61.3% and 91.8%, respectively. What's more, we found that treatment with kurarinol A (1) and the EtOAc extract lead to a significant reduction in hepatotoxicity in response to acute CCl4 exposure. Compared with the model group, experimental results exhibited kurarinol A (10 mg/kg, i.p.) and the EtOAc extract (300 mg/kg, i.p.) could decrease the levels of AST, ALT, ALP and tissue damage. Further mechanistic investigations revealed that up-regulated the mRNA expression of SOD2, Nrf2, OH-1 and down-regulated the IL-1β in liver tissues, respectively. Additionally, Western blot analyses elucidated that inhibition of IL-1β, TLR2, COX-2, NF-κB (p65/p-p65) via TLR2/NF-κB signaling pathway by kurarinol A and the EtOAc extract contribute to its hepatoprotective activity. CONCLUSION These findings demonstrated that the novel compound (kurarinol A, 1) possessed notable hepatoprotective activity against CCl4. It was confirmed that kurarinol A had a certain effect on mice with liver damage induced by CCl4, and its mechanism could be include inhibiting inflammation and reducing of oxidative stress reaction by regulating expression of related genes and proteins. Thus, kurarinol A could as a novel active agent that contributes to the hepatoprotective activity of S. flavescens for the treatment of live injury.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sophora flavescens Aiton (Family: Leguminosae), an herbal plant, has been used in East Asian home remedies for centuries for treating ulcers, skin burns, fevers, and inflammatory disorders. In addition, the dried root of S. flavescens was also applied for antipyretic, analgesic, antihelmintic, and stomachic uses. AIM OF STUDY Nonetheless, how this plant can show various pharmacological activities including anti-inflammatory responses was not fully elucidated. In this study, therefore, we aimed to investigate the curative effects of S. flavescens on inflammation and its molecular mechanism. MATERIALS AND METHODS For reaching this aim, various in vitro and in vivo experimental models with LPS-treated RAW264.7 cells, HCl/EtOH-induced gastric ulcer, and LPS-triggered lung injury conditions were employed and anti-inflammatory activity of S. flavescens methanol extract (Sf-ME) was also tested. Fingerprinting profile of Sf-ME was identified via LC-MS analysis. Its anti-inflammatory molecular mechanism was also examined by immunoblotting analysis. RESULTS Nitric oxide production and mRNA expression levels of iNOS, COX-2, IL-1β, and TNF-α were decreased. Additionally, phosphorylation of Src in the signaling cascade was decreased, and activities of the transcriptional factor NF-κB were reduced as determined by a luciferase reporter assay. Moreover, in vivo, gastritis and lung injury lesions were attenuated by Sf-ME. CONCLUSION Taken together, these findings suggest that Sf-ME could be a potential anti-inflammatory therapeutic agent via suppression of Src kinase activity and regulation of IL-1β secretion.

Abstract
The phytochemical investigation of the roots of the traditional Chinese medicinal plant Sophora flavescens led to the isolation of two novel prenylflavonoids with an unusual cyclohexyl substituent instead of the common aromatic ring B, named 4',4'-dimethoxy-sophvein (17) and sophvein-4'-one (18), and 34 known compounds (1-16, 19-36). The structures of these chemical compounds were determined by spectroscopic techniques, including 1D-, 2D-NMR, and HRESIMS data. Furthermore, evaluations of nitric oxide (NO) production inhibitory activity against lipopolysaccharide (LPS)-treated RAW264.7 cells indicated that some compounds exhibited obvious inhibition effects, with IC50 ranged from 4.6 ± 1.1 to 14.4 ± 0.4 μM. Moreover, additional research demonstrated that some compounds inhibited the growth of HepG2 cells, with an IC50 ranging from 0.46 ± 0.1 to 48.6 ± 0.8 μM. These results suggest that flavonoid derivatives from the roots of S. flavescens can be used as a latent source of antiproliferative or anti-inflammatory agents.

Abstract
Bradyrhizobium arachidis strain CCBAU 051107 could differentiate into swollen and nonswollen bacteroids in determinate root nodules of peanut (Arachis hypogaea) and indeterminate nodules of Sophora flavescens, respectively, with different N2 fixation efficiencies. To reveal the mechanism of bacteroid differentiation and symbiosis efficiency in association with different hosts, morphologies, transcriptomes, and nitrogen fixation efficiencies of the root nodules induced by strain CCBAU 051107 on these two plants were compared. Our results indicated that the nitrogenase activity of peanut nodules was 3 times higher than that of S. flavescens nodules, demonstrating the effects of rhizobium-host interaction on symbiotic effectiveness. With transcriptome comparisons, genes involved in biological nitrogen fixation (BNF) and energy metabolism were upregulated, while those involved in DNA replication, bacterial chemotaxis, and flagellar assembly were significantly downregulated in both types of bacteroids compared with those in free-living cells. However, expression levels of genes involved in BNF, the tricarboxylic acid (TCA) cycle, the pentose phosphate pathway, hydrogenase synthesis, poly-β-hydroxybutyrate (PHB) degradation, and peptidoglycan biosynthesis were significantly greater in the swollen bacteroids of peanut than those in the nonswollen bacteroids of S. flavescens, while contrasting situations were found in expression of genes involved in urea degradation, PHB synthesis, and nitrogen assimilation. Especially higher expression of ureABEF and aspB genes in bacteroids of S. flavescens might imply that the BNF product and nitrogen transport pathway were different from those in peanut. Our study revealed the first differences in bacteroid differentiation and metabolism of these two hosts and will be helpful for us to explore higher-efficiency symbiosis between rhizobia and legumes. IMPORTANCE Rhizobial differentiation into bacteroids in leguminous nodules attracts scientists to investigate its different aspects. The development of bacteroids in the nodule of the important oil crop peanut was first investigated and compared to the status in the nodule of the extremely promiscuous medicinal legume Sophora flavescens by using just a single rhizobial strain of Bradyrhizobium arachidis, CCBAU 051107. This strain differentiates into swollen bacteroids in peanut nodules and nonswollen bacteroids in S. flavescens nodules. The N2-fixing efficiency of the peanut nodules is three times higher than that of S. flavescens. By comparing the transcriptomes of their bacteroids, we found that they have similar gene expression spectra, such as nitrogen fixation and motivity, but different spectra in terms of urease activity and peptidoglycan biosynthesis. Those altered levels of gene expression might be related to their functions and differentiation in respective nodules. Our studies provided novel insight into the rhizobial differentiation and metabolic alteration in different hosts.

Abstract
Pests cause substantial damage to human environments; therefore, studying insecticidal mechanisms is crucial for improving pest control. However, the use of chemical pesticides can cause irreversible secondary damage. In this study, we used network pharmacology to investigate the effect of Sophora flavescens Alt., as a biological pest control agent, on glucose-6-phosphate 1-dehydrogenase, thymidylate synthase, and a translocation protein in aphids. The stability and reliability of target proteins was analyzed using molecular docking and molecular dynamic simulations. Enzyme activity assays validated the feasibility of network pharmacology to obtain actionable targets. We used interdisciplinary integration to study pest control and network pharmacology to identify how Sophora flavescens Alt. resists aphid attacks. The results show that the use of network pharmacology can increase the accuracy and specificity of our predictions for the molecules targeted by insecticides. This approach will facilitate improved, environmentally friendly pest control development in the future.
