[PMID: 37178648 DOI: 10.1016/j.bioorg.2023.106604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/06/2023] [Accepted: 05/05/2023] [Indexed: 05/15/2023]
Abstract
Traditional Chinese medicine is the main source of natural products due to its remarkable clinical efficacy. Syringa oblata Lindl (S. oblata) was widely used because of its extensive biological activities. However, to explore the antioxidant components of S. oblata against tyrosinase, the experiments of antioxidation in vitro were employed. At the same time, the determination of TPC was also use to assess the antioxidant ability of CE, MC, EA and WA fractions and the liver protective activity of the EA fraction was evaluated by mice in vivo. Next, UF-LC-MS technology was performed to screen and identify the efficient tyrosinase inhibitors in S. oblata. The results showed that alashinol (G), dihydrocubebin, syripinin E and secoisolariciresinol were characterized as potential tyrosinase ligands and their RBA values were 2.35, 1.97, 1.91 and 1.61, respectively. Moreover, these four ligands can effectively dock with tyrosinase molecules, with binding energies (BEs) ranging from 0.74 to -0.73 kcal/mol. In addition, tyrosinase inhibition experiment was employed to evaluate the tyrosinase inhibition activities of four potential ligands, the result showed that compound 12 (alashinol G, IC50 = 0.91 ± 0.20 mM) showed the strongest activity to tyrosinase, followed by secoisolariciresinol (IC50 = 0.99 ± 0.07 mM), dihydrocubebin (IC50 = 1.04 ± 0.30 mM) and syripinin E (IC50 = 1.28 ± 0.23 mM), respectively. The results demonstrate that S. oblata might have excellent antioxidant activity, and UF-LC-MS technique is a effective means to filter out tyrosinase inhibitors from natural products.

Abstract
The study aimed to determine the content of phenolic compounds (phenolic acids and flavonoids) and organic acids in dried flowers and water infusions of non-oxidised and oxidised flowers from four lilac cultivars. The diversity in the total phenolic and flavonoid content was in the flowers (18.35-67.14 and 2.03-2.65 mg g-1 DW, respectively) and infusions (14.72-47.78 and 0.20-1.84 mg per 100 mL infusion, respectively) depending the flower colour and form (oxidised and non-oxidised). Phenolic compounds and organic acids were susceptible to oxidation. Compared to infusions, flowers had more phenolic compounds and organic acids. The highest content of most phenolic compounds was confirmed for non-oxidised purple flowers (up to 7825.9 µg g-1 DW for chlorogenic acid) while in infusions for non-oxidised white flowers (up to 667.1 µg per 100 mL infusions for vanillic acid). The phenolic profile of the infusions was less diverse than that of flowers. The scavenging ability ranged from 52 to 87%. The highest organic acid content in flowers was for oxidised blue and purple flowers (2528.1 and 2479.0 µg g-1 DW, respectively) while in infusions the highest organic acid content was for oxidised purple flowers (550.1 µg per 100 mL infusions).

Gender differences pharmacokinetics, bioavailability, hepatic metabolism and metabolism studies of Pinnatifolone A, a sesquiterpenoid compound, in rats by LC-MS/MS and UHPLC-Q-TOF-MS/MS. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 109:154544. [PMID: 36610155 DOI: 10.1016/j.phymed.2022.154544] [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: 09/04/2022] [Revised: 10/19/2022] [Accepted: 11/07/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND Pinnatifolone A is a typical sesquiterpenoid and the primary active ingredient of Syringa oblata Lindl., has potent anti-inflammatory activity. However, Pinnatifolone A pharmacokinetic and metabolites analysis investigations in male and female rats, as well as its in vitro stability in male and female rat liver microsomes, have not been evaluated and compared. PURPOSE To investigate preclinical pharmacokinetic and metabolite in both genders, confirm gender differences, and provide usable information for the development of clinical applications. METHODS A quick, precise, and sensitive LC-MS/MS method was created and effectively used to determine the pharmacokinetics of oral (140 mg/kg) and intravenous (6.3 mg/kg) Pinnatifolone A in male and female rats, in vitro Pinnatifolone A elimination studies in male and female rat liver microsomes. Following that, a UHPLC-Q-TOF-MS/MS technique was established to identify the metabolic profiles of Pinnatifolone A obtained from rat plasma and excreta. RESULTS In the current study, we established for the first time an LC-MS/MS method for the quantitation of Pinnatifolone A with acceptable linearity and selectivity, recovery and matrix effect, accuracy and precision. The absolute oral bioavailability of Pinnatifolone A was approximately 30.36% in female rats, the clearance (CL) was 20.99±3.33 l/h/kg in female rats and 472.37±437.31 l/h/kg in male rats. This difference in rat genders may pertain to the sex-specific expression of hepatic enzymes as demonstrated in the metabolic stability evaluation in the present research; the male rats exhibited higher CLint(mic) (158.83±9.57 μl/min/mg protein) than female rats (76.47±7.90 μl/min/mg protein) liver microsomes, indicating higher Pinnatifolone A clearance in male rats. Twenty-four metabolites were detected and identified in female and male rats; N-acetylcysteine conjugation metabolite was the most abundant metabolites in both rat feces and urine. Furthermore, male and female rats had significantly different levels of the N-acetylcysteine conjugation metabolite. Hydrogenation metabolite was particular to female rats both in rat fecal and urine. Glucuronide conjugation metabolite was the predominant metabolite in rat plasma, and its amount in female rats was double that of male rats. CONCLUSIONS The present research is the first to report the preclinical pharmacokinetics and metabolites of Pinnatifolone A in male and female rats, confirming the gender-based differences. The findings provide a comprehensive overview for further understanding of the pharmacokinetic and metabolic characteristics of Pinnatifolone A and serve as a guide for its future development and utilization.

Abstract
The heartwood of Syringa oblata Lindl. (SO) is one of Mongolian folk medicines to treat insomnia and pain, while its pharmacological evaluation and underlying mechanism remain unclear. In this study, the sedative effect of ethanol extract of SO (ESO) was evaluated with the locomotor activity test and the threshold dose of pentobarbital sodium-induced sleep test in mice, and the hot plate test, acetic acid-induced writhing test, and formalin test in mice were used to evaluate its analgesic effect. The underlying mechanism of ESO analgesia was explored by RT-PCR and western blot analysis, which is associated with the regulation of the NF-κB signaling pathway. Besides, the main constituents of ESO were characterized by LC/MS data analysis and comparison with isolated pure compounds. The current findings brought evidence for clinical application and further pharmacological and phytochemical studies on SO.

Abstract
Syringa oblata is a high ornamental value tree owing to its elegant colors, unique aromas and wide adaptability, however, studies on the molecular mechanism underlying the formation of its ornamental traits are still lacking. Here, we presented a chromosome-scale genome assembly of S. oblata and the final genome size was 1.11 Gb with a contig N50 of 4.75 Mb, anchored on 23 chromosomes and was a better reference for S. oblata transcriptome assembly. Further by integrating transcriptomic and metabolic data, it was concluded that F3H, F3'H, 4CL and PAL, especially the F3'H, were important candidates involved in the formation of floral color differences among S. oblata individuals. Genome-wide identification and analysis revealed that the TPS-b subfamily was the most abundant subfamily of TPS family in S. oblata, which together with the CYP76 family genes determined the formation of the major floral volatiles of S. oblata. Overall, our results provide an important reference for mechanistic studies on the main ornamental traits and molecular breeding in S. oblata.

A chromosome-level genome of Syringa oblata provides new insights into chromosome formation in Oleaceae and evolutionary history of lilacs. THE PLANT JOURNAL : FOR CELL AND MOLECULAR BIOLOGY 2022; 111:836-848. [PMID: 35673966 DOI: 10.1111/tpj.15858] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 05/30/2022] [Accepted: 06/06/2022] [Indexed: 06/15/2023]
Abstract
Lilacs (Syringa L.), a group of well-known ornamental and aromatic woody plants, have long been used for gardening, essential oils and medicine purposes in East Asia and Europe. The lack of knowledge about the complete genome of Syringa not only hampers effort to better understand its evolutionary history, but also prevents genome-based functional gene mining that can help in the variety improvement and medicine development. Here, a chromosome-level genome of Syringa oblata is presented, which has a size of 1.12 Gb including 53 944 protein coding genes. Synteny analysis revealed that a recent duplication event and parallel evolution of two subgenomes formed the current karyotype. Evolutionary analysis, transcriptomics and metabolic profiling showed that segment and tandem duplications contributed to scent formation in the woody aromatic species. Moreover, phylogenetic analysis indicated that S. oblata shared a common ancestor with Osmanthus fragrans and Olea europaea approximately 27.61 million years ago (Mya). Biogeographic reconstruction based on a resequenced data set of 26 species suggested that Syringa originated in the northern part of East Asia during the Miocene (approximately 14.73 Mya) and that the five Syringa groups initially formed before the Late Miocene (approximately 9.97 Mya). Furthermore, multidirectional dispersals accompanied by gene introgression among Syringa species from Northern China during the Miocene were detected by biogeographic reconstruction. Taken together, the results showed that complex gene introgression, which occurred during speciation history, greatly contributed to Syringa diversity.

Abstract
Mailiupian (MLP) is a new patent functional food that consists of Crataegi Fructus, Notoginseng Radix, and Ginkgo Folium, which was reported to be active in improving the microcirculation based on formulation screening. However, whether it is effective in inhibiting thrombus and its mechanism has not been evaluated. Therefore, in the present study, the models of arterial thrombosis induced by FeCl3 and the models of APE by ADP were established to evaluate the antithrombosis effect of MLP. Results showed that MLP markedly reduced the weight and size of wet thrombosis in FeCl3 -induced rats and decreased the recovery time from symptoms of APE mice. MLP was proved to prolong APTT, PT, TT and improve the levels of t-PA and 6-keto-PGF1α significantly, meanwhile, PAI-1 and TXB2 were reduced apparently. By comparing tail bleeding time, MLP showed antithrombotic effects, but without the risk of bleeding, taking aspirin as a control. PRACTICAL APPLICATIONS: Our experiments proved that MLP, a new patent health food, acted on both coagulation and fibrinolytic systems and the platelet aggregation to play antithrombosis roles, providing a theoretical basis for applications of MLP in preventing or curing thrombosis diseases.

Abstract
Syringopicroside is a kind of iridoid monomer compound isolated from Syringa oblata exhibiting a potent effect against hepatitis B virus (HBV). The therapeutic effect and safety of syringopicroside-loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles (SYR-NP) were studied on the model of HBV-infected ducklings and on cultured HepG2.2.15 cells. HBV DNA in ducklings was assessed by fluorescence quantitative PCR. In HepG2.2.15 cells, the content of HBsAg and HBeAg were assayed. Acute toxicity of SYR-NP was studied in ICR mice in 12 h and 7 days after SYR-NP administration. The serum levels of HBV DNA in ducklings treated with SYR-NP in a high dose was significantly lower than in the control. In HepG2.2.15 cells treated with different doses of SYR-NP, the concentrations of HBsAg and HBeAg were significantly below the control. Acute toxicity test showed high safety of SYR-NP. Thus, SYR-NP can inhibit replication of HBV DNA and protect the liver tissue.

All the compounds except compound 2 were identified from A. persica flowers for the first time. The compounds were investigated for their coagulation activity by activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), and bibrinogen (FIB) in vitro. The results of coagulation activity showed that rutin (2), caffeic acid (4), kaempferol-3-O-neohesperidoside (6), kaempferol-3-O-α-L-rhamnoside (11), and kaempferol-3-O-β-D-galactoside (12) exhibited significant procoagulant activity, while chlorogenic acid butyl ester (1) possessed anticoagulant activity in vitro.

Abstract
The ethyl acetate extract of Amygdalus persica L. flowers (family Rosaceae) was fractionated by silica gel and Sephadex LH-20 column chromatography, and, after recrystallization, oleanolic acid (1), ursolic acid (2), quercetin (3), kaempferol (4), hesperetin (5), naringenin (6), and kaempferol-3- O-glucoside (7) were isolated. Their identities were elucidated by spectral techniques and from their physicochemical properties. Compounds 3-7 were identified from A. persica flowers for the first time. All the compounds were evaluated for their procoagulant activity by determining their activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), and fibrinogen (FIB) in vitro. The coagulation activity results showed that oleanolic acid and ursolic acid could significantly prolong APTT and TT; quercetin could significantly shorten PT and TT; kaempferol and hesperetin could significantly shorten APTT, PT, and TT; and naringenin could significantly shorten APTT, PT, and TT and decrease the content of FIB compared with the blank group. All of the above revealed that quercetin, kaempferol, hesperetin and naringenin possessed significant procoagulant activity, while ursolic acid had anticoagulant activity in vitro.

Abstract
Schefflera heptaphylla (L.) Frodin, are commonly used in anti-inflammatory, analgesic, traumatic bleeding and hemostasisas. In this paper, the coagulation effect of the ethanol extract (Set), ethyl acetate phase (Sea) and n-butanol phase (Sbu) was evaluated by prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen content (FIB) assays in vitro. Then, Three main lupanine triterpenes (compounds A-C) were isolated and identified from Sea and Sbu by a bioassay-guided method and their structure were identified as 3α-Hydroxy-lup-20(29)-ene-23, 28-dioic acid, betulinic acid 3-O-sulfate and 3α-Hydroxy-lup-20(29)-ene-23, 28-dioic acid 28-O-(α-l-rhamnopyranosyl(1→4)-O-β-d-glucopyranosyl(1→6))-β-d-glucopyranoside) by spectroscopic data analysis. Among of them, compound B was confirmed to have significant coagulant effect in vitro. Furthermore, the pro-coagulation mechanism of S. heptaphylla extracts and compound B were investigated by measuring whole blood viscosity (WBV), plasma viscosity (PV), erythrocyte sedimentetion rate (ESR), pack cell volume (PCV), APTT, PT, TT, and FIB in vivo. Meanwhile, the levels of thromboxane B2 (TXB2), 6-keto prostaglandin F1α (6-keto-PGF1α), endothelial nitric oxide synthase (eNOS) and (endothelin-1) ET-1 were detected. The bleeding time (BT) was tested by tail bleeding method, which proved the traumatic bleeding and hemostasis activities of S. heptaphylla. The pharmacology experiments showed that the Set, Sea, Sbu and compound B has significant pro-coagulation effect. In addition, compound B might be the main constituent of pro-coagulation in S. heptaphylla These results could support the fact that S. heptaphylla could be used traditionally to cure traumatic bleeding, and the pro-coagulation effects were associated with the regulation of vascular endothelium active substance and hemorheology parameters.
