Abstract
Osteomeles subrotunda is a rare and endangered plant species with extremely small populations. In our study, we sequenced the complete chloroplast (CP) genome of O. subrotunda and described its structural organization, and performed comparative genomic analyses with other Rosaceae CP genomes. The plastome of O. subrotunda was 159,902 bp in length with 36.6% GC content and contained a pair of inverted repeats of 26,367 bp which separated a large single-copy region of 87,933 bp and a small single-copy region of 19,235 bp. The CP genome included 130 genes, of which 85 were protein-coding genes, 37 were transfer RNAs, and eight were ribosomal RNAs. Two genes, rps19 and ycf1, which are located at the borders of IRB/SSC and IRB/LSC, were presumed to be pseudogenes. A total of 61 SSRs were detected, of which, 59 loci were mono-nucleotide repeats, and two were di-nucleotide repeats. The phylogenic analysis indicated that the 14 Rosaceae species were divided into three groups, among which O. subrotunda grouped with P. rupicola, E. japonica, P. pashia, C. japonica, S. torminalis, and M. florentina, and it was found to be a sister clade to C. japonica. Our newly sequenced CP genome of O. subrotunda will provide essential data for further studies on population genetics and biodiversity.

Molecules 2020; 25:E2605. [PMID: 32503323 PMCID: PMC7321095 DOI: 10.3390/molecules25112605] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 05/28/2020] [Accepted: 05/31/2020] [Indexed: 01/06/2023] Open
Abstract
The accumulation and formation of advanced glycation end products (AGEs) are related to diabetes and age-related disease. Osteomeles schwerinae C. K. Schneid. (Rosaceae, OSSC) is used traditionally for the treatment of various diseases in Asia. Previous studies have shown that OSSC elicits preventive effects in an in vivo model of diabetes. This study was to evaluate the antiapoptotic effects of dried leaves and twigs of OSSC extract and its major compounds in ARPE-19 cells-spontaneously arising human retinal pigment epithelial cells-under diabetic conditions. To examine the effects of an OSSC extract and its active compounds (acetylvitexin, hyperoside and quercitrin) on apoptosis in methylglyoxal (MG, the active precursor in the formation of AGEs)-treated ARPE-19 cells and the mechanism by which these effects occur, apoptosis was measured using flow cytometry analysis. Protein expression levels of phospho-p53 (p-p53), Bax and Bcl-2 were determined by western blot analyses. The OSSC extract inhibited apoptosis in MG-treated ARPE-19 cells in a dose-dependent manner. The major compounds also reduced the rate of apoptosis. Both the extract and major compounds also inhibited the expression of p-p53 and Bax and increased the levels of Bcl-2 that had been previously reduced by MG treatment. The OSSC extract (0.1 μg/mL) and its major compounds (0.01 μM) attenuated apoptosis in ARPE-19 cells under toxic diabetic conditions by downregulating of expression of p-p53 and Bax. OSSC may serve as an alternative therapy to retard the development of diabetic retinopathy.

Improvement in Diabetic Retinopathy through Protection against Retinal Apoptosis in Spontaneously Diabetic Torii Rats Mediated by Ethanol Extract of Osteomeles schwerinae C.K. Schneid. Nutrients 2019; 11:nu11030546.

Abstract
Retinal apoptosis plays a critical role in the progression of diabetic retinopathy (DR), a common diabetic complication. Currently, the tight control of blood glucose levels is the standard approach to prevent or delay the progression of DR. However, prevalence of DR among diabetic patients remains high. Focusing on natural nutrients or herbal medicines that can prevent or delay the onset of diabetic complications, we administered an ethanol extract of the aerial portion of Osteomeles schwerinae (OSSCE), a Chinese herbal medicine, over a period of 17 weeks to spontaneously diabetic Torii (SDT) rats. OSSCE was found to ameliorate retinal apoptosis through the regulation of advanced glycation end product (AGE) accumulation, oxidative stress, and mitochondrial function via the inhibition of NF-κB activity, in turn, through the downregulation of PKCδ, P47phox, and ERK1/2. We further demonstrated in 25 mM glucose-treated human retinal microvascular endothelial cells (HRMECs) that hyperoside (3-O-galactoside-quercetin), quercitrin (3-O-rhamnoside-quercetin), and 2″-O-acetylvitexin (8-C-(2″-O-acetyl-glucoside)-apigenin) were the active components of OSSCE that mediated its pharmacological action. Our results provide evidence that OSSCE is a powerful agent that may directly mediate a delay in the development or disease improvement in patients of DR.

Abstract
Mesangial cell proliferation contributes to the development of glomerulosclerosis in diabetic nephropathy. This study was aimed at determining whether Osteomeles schwerinae (OSSC) extract can ameliorate renal damage in Spontaneously Diabetic Torii (SDT) rats. OSSC extract (100 and 250 mg/kg/day) was administered to the SDT rats through oral gavage for 17 weeks. At the end of the experiment, glucose, HbA1c, and albuminuria were measured. In addition, the levels of mesangial proliferation-related proteins were determined by western blotting and immunohistochemistry. Our results show that albuminuria, accumulation of the extracellular matrix (ECM), and renal expansion were markedly restored by OSSC extract administration. The OSSC treatment also inhibited α-smooth muscle actin and transforming growth factor-β1 protein expression. In addition, OSSC and its bioactive compounds hyperoside and quercitrin inhibited the platelet-derived growth factor-BB (PDGF-BB)/platelet-derived growth factor-B receptor (PDGFR-β) ligand binding in an in vitro assay. Taken together, these results indicate that OSSC inhibits ECM accumulation and mesangial proliferation of the glomeruli in SDT rats through inhibition of the interaction between PDGF-BB and PDGFR-β. OSSC has ameliorating effects on the initiation and progression of diabetes complications and can be used for the treatment of early diabetic renal dysfunction.

Abstract
The beneficial effects of liquorice in treating chills, colds, and coughs have been fully discussed in Ayurveda, as well as in the texts of ancient Egyptians, Greeks, and Romans. The plant has been prescribed for dropsy during the period of famous Hippocrates. The reason being that it was quite helpful as thirst-quenching drugs (Biondi et al. in J Nat Prod 68:1099–1102, 2005; Mamedov and Egamberdieva in Herbals and human health-phytochemistry. Springer Nature Publishers, 41 pp, 2017). No doubt, the clinical use of liquorice in modern medicine started around 1930; Pedanios Dioscorides of Anazarba (Adana), first century AD-Father of Pharmacists, mentions that it is highly effective in the treatment of stomach and intestinal ulcers. In Ayurveda, people in ancient Hindu culture have used it for improving sexual vigor.

Abstract
BACKGROUND Osteomeles schwerinae C. K. Schneid. (Rosaceae, OSSC) is a medicinal plant traditionally used to treat various diseases in Asia. The chemical constituents of OSSC have an inhibitory effect on aldose reductase activity, which has been implicated in the pathogenesis of diabetic complications. However, the protective effects of the pharmacological activity and potential mechanisms in diabetic nephropathy are still not known. OBJECTIVE In the present study, OSSC extracts and major compounds were examined for their effects on binding to the receptors of advanced glycation end products (RAGE) and on transforming growth factor-beta1 (TGF-β1) expression-related signal mechanisms in mouse glomerular mesangial cells (GMCs). MATERIALS AND METHODS A simple, rapid and efficient method was developed for the simultaneous determination of the marker compounds in the ethanol extract of the leaves and twigs of OSSC using HPLC-diode array detector (DAD). In this study, we determined the effects of OSSC extract and hyperoside on AGE and RAGE binding, and studied the mechanism of OSSC extract effects on AGE-bovine serum albumin (BSA)-treated GMCs. GMCs overexpressing human RAGE were cultured in AGE-BSA labeled with Alexa 488, and OSSC extract. AGE/RAGE binding were measured using fluorescence (excitation 485 nm/emission 528 nm). TGF-β1 protein expression levels were determined by western blot analyses. RESULTS OSSC extracts of leaves and twigs inhibited on AGE/RAGE binding and TGF-β1 protein expression in a dose-dependent manner in GMCs. Furthermore, OSSC extracts reduced the effects on AGE-BSA-induced reactive oxidative species (ROS) formation and nuclear translocalization of transcription factor NF-κB. OSSC extracts inhibited phosphorylation of extracellular signal-regulated protein kinases1/2 (ERK1/2), p38 mitogen-activated protein kinases (p38MAPK), and IκB. Hyperoside also inhibited AGE/RAGE binding and ROS formation, and reduced TGF-β1 expression and IkB phosphorylation. CONCLUSIONS OSSC extracts and hyperoside may attenuate AGE/RAGE binding and expression of TGF-β1 by downregulating of pERK1/2, p38MAPK and IκB phosphorylations in GMCs under diabetic condition and retard the development of diabetic complications such as diabetic nephropathy.

Abstract
In the pathophysiology of diabetic retinopathy (DR), advanced glycation end products (AGEs) and vascular endothelial growth factor (VEGF) are thought to have important roles. It is known that VEGF causes a breakdown of the blood‑retinal barrier (BRB) and retinal neovascularization; however, how AGEs affect the retina has largely remained elusive. OSSC1E‑K19 is a novel phytochemical component of Osteomeles schwerinae. The objective of the present study was to evaluate the protective effects of OSSC1E‑K19 on retinal vascular injury in AGE‑modified rat serum albumin (AGE-RSA)-induced retinopathy. AGE-RSA-injected rat eyes were used investigate the protective effects of OSSC1E‑K19 on BRB breakdown. Intravitreal injection of OSSC1E-K19 prevented AGE-RSA-induced BRB breakdown and decreased retinal VEGF expression in retinal vessels. In addition, OSSC1E-K19 inhibited the loss of occludin, a significant tight junction protein. These results supported the potential therapeutic utility of OSSC1E-K19 for retinal vascular permeability diseases.

Abstract
Three new phenolic biphenyl derivatives (1-3) and one new lignan glycoside (4) were isolated from the leaves and twigs of Osteomeles schwerinae. The structures of the new compounds were established by spectroscopic data interpretation. The inhibitory effects of 1-4 on rat lens aldose reductase in vitro were examined, and compounds 1-3 markedly inhibited the enzyme with IC50 values of 3.8 to 13.8 μM. In addition, the effects of these isolates on the dilation of hyaloid-retinal vessels induced by high glucose (HG) in zebrafish larvae were investigated. Compound 1 was the most effective in reducing HG-induced dilation of hyaloid-retinal vessels.

Abstract
Advanced glycation end products (AGEs) are involved in the development of diabetic complications such as diabetic retinopathy. 5'-methoxybiphenyl-3,4,3'-triol (referred to as K24) was isolated using bioactivity-guided fractionation of Osteomeles schwerinae C. K. Schneid. and identified as a potent AGE inhibitor. To identify the protective effect of K24 on disruption of the blood-retinal barrier, AGE-RSA was intravitreally injected into rat eyes. K24 had an inhibitory effect on AGE-RSA-induced retinal vascular leakage by suppressing the expression of vascular endothelial growth factor (VEGF) and decreasing the loss of occludin. In addition, we examined whether K24 has a preventive effect against retinal pathogenic angiogenesis in an oxygen-induced retinopathy (OIR) mouse model. K24 significantly reduced the retinal non-perfused area and neovascular tufts in the OIR mice. These data indicate that K24 could serve as an innovative pharmaceutical agent to prevent blood-retinal barrier breakage and retinal pathogenic angiogenesis through an anti-VEGF mechanism.

Abstract
High-speed countercurrent chromatography (HSCCC) was successfully applied to the isolation and purification of four flavonoids from Herba Salviae Plbeiae using stepwise and dual-mode elution with a pair of two-phase solvent systems. The systems composed of n-hexane-chloroform-methanol-water (0.5 : 4 : 3 : 2, v/v/v/v) and chloroform-methanol-water (4 : 3 : 2, v/v/v). Analytical HSCCC was used for the preliminary selection of a suitable system, and a linear scale-step procedure was performed at a preparative grade. Hispidulin (91 mg), nepetin (148 mg), homoplantaginin (405 mg) and nepetin-7-glucoside (192 mg) could be obtained from 1,500-mg crude sample in a one-step separation, with purities >95% as determined by high-performance liquid chromatography. Their chemical structures were identified by (1)H nuclear magnetic resonance (NMR) and (13)C NMR.

Abstract
Glycyrrhiza uralensis (or licorice) is a widely used Oriental herbal medicine from which the phenylflavonoids dehydroglyasperin C (DGC), dehydroglyasperin D (DGD), and isoangustone A (IsoA) are derived. The purpose of the present study was to evaluate the antioxidant properties of DGC, DGD, and IsoA. The three compounds showed strong ferric reducing activities and effectively scavenged DPPH, ABTS+, and singlet oxygen radicals. Among the three compounds tested, DGC showed the highest free radical scavenging capacity in human hepatoma HepG2 cells as assessed by oxidant-sensitive fluorescent dyes dichlorofluorescein diacetate and dihydroethidium bromide. In addition, all three compounds effectively suppressed lipid peroxidation in rat tissues as well as H2O2-induced ROS production in hepatoma cells. This study demonstrates that among the three phenylflavonoids isolated from licorice, DGC possesses the most potent antioxidant activity, suggesting it has protective effects against chronic diseases caused by reactive oxygen species as well as potential as an antioxidant food additive.

Abstract
Countercurrent Chromatography (CCC) provides the natural product chemist with a high-resolution separatory method, which is uniquely applicable to sensitive (unstable) compounds and which allows virtually quantitative recovery of the load sample. Different instruments use different means of retaining a stationary liquid phase. The solvent system (SS) can be chosen to optimize the separatory power and the number of systems available is limitless. Several examples are provided to illustrate the power of the method and to guide the chemist in choice of an appropriate SS.

Abstract
This study employed the online HPLC-2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS)(+) bioassay to rapidly determine the antioxidant compounds occurring in the crude extract of Alnus japonica. The negative peaks of the ABTS(+) radical scavenging detection system, which indicated the presence of antioxidant activity, were monitored by measuring the decrease in absorbance at 734 nm. The ABTS(+)-based antioxidant activity profile showed that three negative peaks exhibited antioxidant activity. High-speed counter-current chromatography (HSCCC) was used for preparative scale separation of the three active peaks from the extract. The purity of the isolated compounds was analyzed by HPLC and their structures were identified by (1)H- and (13)C-nuclear magnetic resonance spectrometry (NMR), heteronuclear multiple bond correlation (HMBC), and heteronuclear single quantum correlation (HSQC). Two solvent systems composed of n-hexane/ethylacetate/methanol/water (4:6:4:6, v/v) and of ethyl acetate/methanol/water (1:0.1:1, v/v) were performed in high-speed counter-current chromatography. Consequently, a total of 527 mg of hirsutanonol 5-O-β-D-glucopyranoside, 80.04 mg of 3-deoxohirsutenonol 5-O-β-D-glucopyranoside, and 91.0 mg of hirsutenone were obtained with purity of 94.7, 90.5, and 98.6%, respectively.

Screening and characterization of natural antioxidants in four Glycyrrhiza species by liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry. J Chromatogr A 2011; 1218:8181-91.

Abstract
Licorice, derived from the dried roots and rhizomes of several species of genus Glycyrrhiza L. (Leguminosae family), has been traditionally used in herbal medicine for over 4000 years. In recent years, the interest in antioxidative constituents in licorice has greatly increased. In this work, a new method based on 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) spiking test combined with HPLC coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (Q-TOF MS/MS) analysis was developed to screen and identify the antioxidants in licorice. The results of the method validation indicated that the developed method was reliable and repeatable. Compared with DPPH on-line method, the HPLC-Q-TOF MS/MS method combined with DPPH spiking test offered much higher sensitivity and resolution. Using this method, 35 radical scavengers were screened from four Glycyrrhiza species (G. inflata, G. glabra, G. pallidiflora and G. uralensis), and 21 of them were unambiguously or tentatively identified by HPLC-Q-TOF MS/MS. Among the 21 identified flavonoids, 10 compounds had been reported to possess antioxidative activities in the previous studies, and the radical scavenging activities of the other 11 compounds were reported for the first time. The effects of six purified flavonoids on DPPH radical and lipid peroxidation were evaluated for validation of the developed method. The results indicated that HPLC-Q-TOF MS/MS coupled with DPPH treatment is an efficient and powerful method to discover the potential antioxidative compounds from the complex natural product mixtures. In this study, the identified components with free radical scavenging activity, would help to explain the therapeutic benefit of licorice in the treatment of human disease associated with oxidative stress.
