Abstract
The root Rhynchosia volubilis was widely used for contraception in folk medicine, although its molecular mechanism on antifertility has not yet been revealed. In human sperm, it was reported that the cation channel of sperm, an indispensable cation channel for the fertilization process, could be regulated by various steroid-like compounds in plants. Interestingly, these nonphysiological ligands would also disturb the activation of the cation channel of sperm induced by progesterone. Therefore, this study aimed to explore whether the compounds in R. volubilis affect the physiological regulation of the cation channel of sperm. The bioguided isolation of the whole herb of R. volubilis has resulted in the novel discovery of five new prenylated isoflavonoids, rhynchones A - E (1: - 5: ), a new natural product, 5'-O-methylphaseolinisoflavan (6: ) (1H and 13C NMR data, Supporting Information), together with twelve known compounds (7: - 18: ). Their structures were established by extensive spectroscopic analyses and drawing a comparison with literature data, while their absolute configurations were determined by electronic circular dichroism calculations. The experiments of intracellular Ca2+ signals and patch clamping recordings showed that rhynchone A (1: ) significantly reduced cation channel of sperm activation by competing with progesterone. In conclusion, our findings indicat that rhynchone A might act as a contraceptive compound by impairing the activation of the cation channel of sperm and thus prevent fertilization.

Abstract
This study was conducted to further investigate bioactive molecules from Sophora tonkinensis that can inhibit proprotein convertase substilisin/kexin type 9 (PCSK9) expression. After interpreting NMR spectroscopic data and MS spectral data of all isolates, a new naturally occurring compound, 6-hydroxy-vitexin-2″-O-rhamnoside (7), was identified along with 30 known compounds. The calculation of the gauge-including atomic orbital (GAIO) and electronic circular dichroism (ECD) proposed the absolute configuration of 17 as (2S,3R)-methyl-2-(4-hydroxybenzyl)tartrate by comparing the calculated ECD with experimental data. All isolates were tested for their inhibitory effects on PCSK9 mRNA expression. Of the tested compounds, (+)-isolariciresinol (12) inhibited PCSK9 expression via downregulation of HNF1α and SREBPs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sophora Tonkinensis Gagnep. (STG) has been used as a folk medicine for the treatment of different cancers, especially for nasopharyngeal carcinoma, cervical cancer, liver cancer, stomach cancer, lung cancer and leukemia in China. However, the main chemical composition and anticancer mechanism of chloroform extract of STG (CESTG) were still not very clear. AIM OF STUDY This work was carried out to investigate the anticancer effects and mechanisms of chloroform extract of STG (CESTG) on NPC. METHODS Cultured NPC CNE1, CNE2 and Np69 cells were treated with CESTG. Cells were subjected to cell proliferation, colony-forming, migration and invasion assays. Cell cycle and apoptosis were measured by flow cytometry. Western blotting and morphological analysis were also performed. Tumor xenografts and drug treatments were made in BALB/c nude mice. The main compounds of CESTG was separated by HPLC. RESULTS CESTG inhibited cell viability, clonal growth and induced cell apoptosis in a dose-dependent manner by silencing the PI3K/AKT/mTOR signaling pathway, which is associated with upregulation of cleaved PARP, caspase 3/7/8/9, cleaved caspase 3/7/8/9, Bax and downregulation of PARP, P-PI3K, PI3K, P-AKT, AKT, P-mTOR, mTOR and Bcl-2. In addition, CESTG arrested cell cycle in the G1/S phase, correlating with decreased levels of cyclin D1/B1, CDK 4 and 6. CESTG decreased cell migration and invasion which correlated with decreased expression of β-catenin, vimentin and snail. CESTG significantly inhibited the tumor growth without toxicity. CONCLUSION The results presented here suggest that CESTG could be use as a potential source of NPC therapeutic drug.

Abstract
Sophora tonkinensis Gagnep. (ST) (Fabaceae) is distributed chiefly in south-central and southeast China and Vietnam. In traditional Chinese medicine theory, the root and rhizome of ST are toxic and mainly used in the treatment of pharyngeal and laryngeal diseases. Modern studies provide new insights into the pharmacological and toxicological aspects of ST. The pharmacological and toxicological properties of ST were reviewed in this paper based on the literature from Google Scholar and CNKI, and the bioinformatics platforms were applied to explore the pharmacological and toxicological potentials of ST. The results of the literature analysis showed that ST has hepatoprotective, immunomodulatory, and anticancer effects and produces obvious toxicity to the liver and nervous and cardiovascular system. The results of bioinformatics showed that the compounds from ST may be applied to the treatment of cancer and digestive and nervous system diseases and show the possibility to cause hematotoxicity, neurotoxicity, and immunotoxicity. The present review demonstrates that attention should be paid to the potential toxicity of ST in the treatment of diseases and provides the reference for the subsequent pharmacological toxicological studies on the mechanism and chemical basis of ST.

Abstract
Total flavonoids of S. tonkinensis showed obvious anticomplement activity after incubated with human intestinal bacteria. Eighteen flavonoids were identified from TFST and its metabolites by UPLC-ESI- LTQ/MS. Five glycosides were metabolized into three aglycones with more potent anticomplement activity.
Anticomplement activity played an important role in anti-inflammatory effects of traditional Chinese herbs. The total flavonoids of Sophora tonkinensis (TFST) were inactive on the complement system but showed obvious anticomplement activity after incubated with human intestinal bacteria in vitro. In order to discover the metabolic activation of TFST by intestinal flora, the constituents of TFST and its metabolites were identified by UPLC-ESI-LTQ/MS. Their anticomplement activities were evaluated through the classical and alternative pathway. As a result, eighteen flavonoids were identified, including seven flavonoid glycosides, five aglycones and six isoprenylated flavonoids. All the glycosides (daidzein-4′-glucoside-rhamnoside, sophorabioside, rutin, isoquercitrin, quercitrin, ononin, trifolirhizin) were metabolized into their corresponding aglycones in different extent by human intestinal bacteria, resulting in the contents of the five aglycones were highly increased in 24 h. However, no changes have occurred on the six isoprenylated flavonoids. Interestingly, three aglycones (quercetin, formononetin and maackiain) had significantly more potent anticomplement activities than their prototype glycosides. The results indicated that the enhancement of TFST anticomplement activity was attributed to the active aglycones, especially formononetin and quercetin, produced by human intestinal bacteria. These aglycones are likely to be among the potential active components of S. tonkinensis for its inhibiting inflammation effects.

Abstract
BACKGROUND The genus Sophora (Fabaceae) represents one of the important medicinal plant genera regarding its chemical constituents and outstanding pharmacological activities. PURPOSE In this review, we surveyed the latest findings on the bioactivities of different Sophora extracts and isolated phytochemicals during the past 8 years (2011-2019) updating the latest review article in 2011. The aim of this review is to focus on the molecular pharmacology of Sophora species to provide the rationale basis for the development of novel drugs. RESULTS Sophora and its bioactive compounds possess outstanding pharmacological properties, especially as anticancer and anti-inflammatory drugs, in addition to its antioxidant, antibacterial, antifungal and antiviral properties. CONCLUSION Based on their use in traditional medicine, Sophora species exert a plethora of cellular and molecular activities, which render them as attractive candidates for rationale drug development. Randomized, placebo-controlled clinical trials are required for further integration of Sophora-based phototherapies into conventional medicine.

Abstract
For the full development and utilization of Sophora tonkinensis Gagnep., this study was primarily intended to established a simple and efficient approach for the preparative purification of total flavonoids from S. tonkinensis by macroporous resin column chromatography (MRCC). The adsorption and desorption characteristics of the total flavonoids on ten macroporous resins were first studied, and AB-8 resin was chosen as the most suitable, and the adsorption data were best fitted to the pseudo-second-order kinetics model and Langmuir isotherm model. Furthermore, the technological parameters for the purification of the total flavonoids were optimized using column chromatography. After a sample one-step purification procedure, the content of the total flavonoids increased by about 4.76-fold from 12.14% to 57.82%, with a recovery yield of 84.93%. In addition, the comparative analysis of the flavonoid extracts before and after purification was performed by high-performance liquid chromatography coupled with photodiode-array detection (HPLC-PAD). The results showed that the contents of six major flavonoids in the purified product were all higher than before the purification. Therefore, the AB-8 MRCC established in this work was a promising method for the industrial-scale purification of the total flavonoids from S. tonkinensis.

Abstract
Neuroinflammation underlies many neuro-degenerative diseases. In this paper, we report the identification of a new pterocarpan-type anti-inflammatory compound named sophotokin isolated from Sophora tonkinensis. S. tonkinensis has been used traditionally for treatment of conditions related to inflammation. Our initial screening showed that sophotokin dose-dependently inhibits lipopolysaccharide (LPS)-stimulated production of NO, TNF-α, PGE2, and IL-1β in microglial cells. This antineuroinflammatory effect was associated with sophotokin's blockade of LPS-induced production of the inflammatory mediators iNOS and COX-2. Western blot and qPCR analysis demonstrated that sophotokin inhibits both the p38-MAPK and NF-κB signal pathways. Further studies revealed that sophotokin also suppresses the expression of cluster differentiation 14 (CD14) in the toll-like receptor 4 (TLR4) signaling pathway. Following down-regulation of MyD88 and TRAF6, sophotokin inhibits the activation of the NF-κB and MAPK signal pathways in LPS-induced BV-2 cells. In silico studies suggested that sophotokin could interact with PU.1-DNA complex through hydrogen binding at sites 1 and 2 of the complex, blocking the DNA binding. This suggests that PU.1 may be a potential target of sophotokin. Taken together, these results suggest that sophotokin may have therapeutic potential for diseases related to neuroinflammation. The mechanism of antineuroinflammatory effects involves inhibition of the TLR4 signal pathway at the sites of NF-κB and MAPK with PU.1 as a likely upstream target.

Abstract
Phytochemical analysis of the ethanolic extract of Maclura pomifera fruits yielded four new compounds (I-IV) along with eleven known compounds (V-XV). The crude extract exhibited significant activity towards cannabinoid receptors (CB1: 103.4% displacement; CB2: 68.8% displacement) and possibly allosteric interaction with δ and μ opioid receptors (-49.7 and -53.8% displacement, resp.). Compound I was found to be possibly allosteric for κ and μ opioid receptors (-88.4 and -27.2% displacement, resp.) and showed moderate activity (60.5% displacement) towards CB1 receptor. Compound II exhibited moderate activity towards cannabinoid receptors CB1 and CB2 (47.9 and 42.3% displacement, resp.). The known compounds (V-VIII) exhibited prominent activity towards cannabinoid receptors: pomiferin (V) (IC50 of 2.110 and 1.318 μM for CB1 and CB2, resp.), auriculasin (VI) (IC50 of 8.923 μM for CB1), warangalone (VII) (IC50 of 1.670 and 4.438 μM for CB1 and CB2, resp.), and osajin (VIII) (IC50 of 3.859 and 7.646 μM for CB1 and CB2, resp.). The isolated compounds were also tested for inhibition of human monoamine oxidase-A and monoamine oxidase-B enzymes activities, where all the tested compounds showed fewer inhibitory effects on MAO-A compared to MAO-B activities: auriculasin (VI) (IC50 of 1.91 and 45.98 μM for MAO-B and MAO-A, resp.).

[PMID: 25173460 DOI: 10.1016/j.fitote.2014.08.019] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2014] [Revised: 08/19/2014] [Accepted: 08/21/2014] [Indexed: 12/30/2022]
Abstract
Two novel 2-arylbenzofuran dimers, shandougenines A (1) and B (2), and two new polyisoprenylated flavanones 3 (shandougenine C) and 4 (shandougenine D) were isolated from the 95% EtOH extract of Sophora tonkinensis, together with 18 known compounds. Their structures were determined on the basis of spectral data interpretation and by comparing the spectral data with that reported previously for known compounds. Shandougenine A (1) is a unique dimeric 2-arylbenzofuran with a C-3C-5‴ bond linkage. Shandougenine B (2) is the first naturally occurring dimeric 2-arylbenzofuran with a novel C-3C-3″ bond linkage. Compound 1 showed moderate DPPH free radical scavenging capacity, whereas 2 has stronger DPPH free radical and ABTS cation radical scavenging capacity than Vc. Compounds 12, 19, and 20 showed parallel DPPH free radical scavenging capacity with Vc. Compounds 1, 3, 4, 19, 20, and 22 have parallel ABTS cation radical scavenging capacity to Vc. Compounds 1, 3, 4, and 18 showed slightly stronger superoxide anion radical scavenging capacity than the known flavanone luteolin. The antioxidant activities of shandougenines A (1) and B (2) indicated that compounds 1 and 2 may represent novel scaffolds for the development of new antioxidants.

Abstract
Two new isoflavone tetraglycosides ( 1 and 2) and six known compounds were isolated from the leaves of Sophora japonica. The new glycosides are genistein 7- O-beta- d-glucopyranoside-4'- O-(6'''- O-alpha- l-rhamnopyranosyl)-beta-sophoroside ( 1) and genistein 7- O-alpha- l-rhamnopyranoside-4'- O-(6'''- O-alpha- l-rhamnopyranosyl)-beta-sophoroside ( 2). The structures of compounds 1 and 2 were established primarily by NMR experiments and chemical methods, and they are the first reported naturally occurring isoflavone glycosides with four attached sugar residues.
