New lignan glycosides from Justicia secunda Vahl (Acanthaceae) with antimicrobial and antiparasitic properties

Three new lignan glucosides, namely, justisecundosides A (1), B (2a), and C (2b), were isolated from the whole plant of Justicia secunda together with seven known compounds (3−9). Their structures were established based on a comprehensive analysis of HR-ESI-MS, IR, UV, and CD, in conjunction with their 1D and 2D-NMR data. A putative biogenetic pathway of compounds 1−2a,b from coniferyl alcohol was proposed. In addition, the antimicrobial activities of the extract, fractions, and some isolated compounds were assessed against multiresistant bacterial and fungal strains. Furthermore, the antiplasmodial, antileishmanial, and antitrypanosomal activities were assessed against the sensitive (3D7) and multidrug-resistant (Dd2) strains of P. falciparum, promastigote and bloodstream forms of L. donovani, and Trypanosoma brucei, respectively. Compound 4 exhibited moderate antibacterial activity against Staphylococcus aureus SA RN 46003 with a MIC value of 62.5 μg/mL. Besides, compound 6 demonstrated a very good activity against sensitive (IC50Pf3D7: 0.81 μg/mL) and multidrug-resistant (IC50PfDd2: 14.61 μg/mL) strains of P. falciparum while compound 4 displayed good antitrypanosomal activity (IC50: 1.19 μg/mL). Also, compound 1 was the most active on the promastigote form of L. donovani with an IC50 of 13.02 μg/mL.

Lignan glucosides from Gentiana macrophylla with potential anti-arthritis and hepatoprotective activities

Ten lignans, including six previously undescribed phenolic ester glycosyl lignans (1–6), were isolated from a well-known traditional Chinese medicine, Qin-Jiao, which is the dry root of Gentiana macrophylla Pall. (Gentianaceae). Their structures were determined by spectroscopic and chemical methods, especially 2D NMR techniques. Quantum chemical calculations of theoretical ECD spectra allowed the determination of their absolute configurations. Refer to its traditional applications for the treatment of rheumatic arthralgia and hepatopathy, these compounds were evaluated on a TNF-α induced MH7A human synoviocyte inflammation model and a D-GalN induced AML12 hepatocyte injury model. Compounds 1, 2, 5, and 6 significantly reduced the release of proinflammatory cytokine IL-1β in MH7A cells at 15 μM and they also could strongly protect AML12 cells against D-GalN injury at 30 μM. Flow cytometry and Western blot analysis showed that compound 5 ameliorated D-GalN induced AML12 cell apoptosis by upregulating the expression of anti-apoptotic Bcl-2 protein and down-regulating the expression of pro-apoptotic Bax protein.

Optimizing conditions for the recovery of lignans from sesame cake using three green extraction methods: Microwave-, ultrasound- and accelerated-assisted solvent extraction

Lignans, a group of polyphenolic low molecular weight bioactive compounds with health benefits, are major constituents of sesame cake (SC), a by-product derived from sesame oil processing. The utilization of this by-product in the food or nutraceutical industries could explore its valorization route in compliance with sustainability and circular economy principles. This study aimed to investigate the impact of different environmental-friendly processing approaches such as ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE) and accelerated solvent extraction (ASE) for lignans extraction from SC using central composite design (CCD) with response surface methodology (RSM). Sesaminol triglucoside (SETRI) and sesaminol diglucoside (SEDI) were identified and quantified as the major lignan glucosides in SC. Ethanol/water mixture was selected as ‘green’ solvent for all extraction methods. The influence of ethanol concentration (X1), extraction time (X2), temperature (X3) and solid-to-solvent (SS) ratio or solid weight (X4) on extraction yield (EY), SETRI and SEDI contents for each technique was examined. The developed models exhibited a high degree of desirability (> 0.72) with determined optimal levels of extraction parameters as follows: X1 = 71%, X2 = 10 min, X3 = 50 °C, X4 = 1.50 g/20 mL for UAE; X1 = 80%, X2 = 5 min, X3 = 50 °C, X4 = 0.85 g/20 mL for MAE; X1 = 80%, X2 = 20 min, X3 = 65 °C, X4 = 2 g for ASE. Under these optimal conditions, the experimental values for EY, SETRI and SEDI contents in SC extracts were: 8.28%, 105.98 mg/g and 16.93 mg/g, respectively for UAE; 8.75%, 105.41 mg/g and 18.76 mg/g, respectively for MAE; 9.34%, 108.00 mg/g and 18.34 mg/g, respectively for ASE. The ANOVA analysis from the RSM were fitted with quadratic models yielding acceptable R2 (> 0.87), adjusted R2 (> 0.77), predicted R2 (> 0.74), and nonsignificant lack-of-fit (p > 0.05) values. Ethanol concentration and solid-to-solvent ratio were the most influencing factors affecting lignans extraction. Although ASE was found as the most suitable method for extracting lignans from SC, from an industrial viewpoint, UAE could be a more affordable technique due to advances in ultrasonic processing devices for large scale applications.

The structures of all compounds were elucidated by extensive spectroscopic data analysis(UV, IR, HR-ESI-MS, ECD and NMR) as(-)-4-epi-lyoniresinol-9'-O-α-L-rhamnopyranoside(1),(+)-lyoniresinol-3α-O-α-L-rhamnopyranoside(2),(+)-5'-methoxyisolariciresinol-9'-O-α-L-rhamnopyranoside(3),(-)-lyoniresinol-3α-O-β-D-glucopyranoside(4),(+)-lyoniresinol-3α-O-β-D-glucopyranoside(5),(-)-4-epi-lyoniresinol-9'-O-β-D-glucopyransoide(6), racemiside(7), neociwujiaphenol(8),(+)-syringaresinol(9), and homohesperitin(10). Among them, compound 1 was a new aryltetralin-type lignan. All the isolated lignans were tested for antioxidant activities in Fe~(2+)-cysteine induced rat liver microsomal lipid peroxidation in vitro, and compounds 8 and 9 showed antioxidant activities on the formation of malondiadehyde(MDA) in rat liver microsomes at 1×10~(-5) mol·L~(-1), with significant inhibitory rates of 75.20% and 91.12%, respectively.

In vitro cytotoxic activity-guided isolation studies on the underground parts of Valeriana speluncaria Boiss.

Two unreported neolignans, speluncarins A (1) and B (2) together with seven known compounds (3–8, 13) were isolated from the underground parts of Valeriana speluncaria Boiss through cytotoxic activity-guided fractionation method. The crude extract, subextracts, main fractions and isolates were evaluated for their in vitro cytotoxic activities against MCF-7 and U87 cancer cell lines as well as HUVEC cell line by MTS assay. Although the crude EtOH extract, CHCl3 and EtOAc subextracts as well as some fractions exhibited remarkable cytotoxic effect against tested cancer cell lines, the purified compounds did not demonstrate promising activity in the tested concentrations. Besides these studies, five known lignan glucosides (8–12) were obtained from the inactive n-BuOH subextract. The structures of the isolates were elucidated by extensive 1D and 2D NMR spectroscopy and HR-MS analysis. This is the first phytochemical and bioactivity study on V. speluncaria, an endemic species to Turkey.

Glycosylated coumarins, flavonoids, lignans and phenylpropanoids from Wikstroemia nutans and their biological activities.

The new structure including its absolute configuration was elucidated based on a combination of 1D and 2D NMR, UV, IR, HRESIMS spectroscopic data, as well as chemical transformation. Compounds 1–17 were first isolated from the plant species W. nutans, while compounds 1–3, 8, and 11 were reported from the genus Wikstroemia for the first time. All co-isolates were evaluated for their in vitro inhibitory effects on nitric oxide (NO) production induced by lipopolysaccharide (LPS) in murine RAW264.7 macrophage cells. The antibacterial activity of the selected compounds was also tested. Our work enriches the structure diversity of the secondary metabolites from the genus Wikstroemia.

Distribution of lignans and lignan mono/diglucosides within Ginkgo biloba L. stem

To investigate the biosynthetic pathways and regulatory mechanisms of lignans in plants, the actual distributions of lignans and lignan glucosides in flash-frozen stems of Ginkgo biloba L. (Ginkgoaceae) were studied using cryo time-of-flight secondary ion mass spectrometry coupled with scanning electron microscopy (cryo-TOF-SIMS/SEM). Four lignans and four lignan glucosides were successfully characterized. Quantitative HPLC measurements were conducted on serial tangential sections of freeze-fixed ginkgo stem to determine the amount and approximate distribution of lignan and lignan glucosides. (−)-Olivil 4,4′-di-O-β-d-glucopyranoside (olivil DG) was the most abundant lignan glucoside in ginkgo and was distributed mainly in the phloem, ray parenchyma cells, and pith. The comparative accumulation of olivil DG revealed its possible transport pathways and storage sites in ginkgo. Although not all relevant enzymes have been identified, understanding the distributions of lignan and lignan glucosides in ginkgo stems provides significant insight into their biological functions.

Tetrahydronaphthalene lignan glucoside from Crataeva nurvala: Apoptotic induction, antimigration, and in silico analysis

Background: Crataeva nurvala is an important plant having wide application in Ayurveda and Siddha. It is extensively used in formulations for patients suffering from benign prostatic hyperplasia. Objective: Isolation, characterization, and evaluation of cytotoxic activity of bioactive fraction of C. nurvala and identification of molecular target prediction by suitable method. Materials and Methods: Gravity column chromatography followed by HPLC of the bioactive n-butanol fraction afforded compound 1. Besides cell proliferation, apoptotic index and cell migration were studied to determine the efficacy of the compound against cancer cells. Results: The cell cycle analysis revealed that the compound 1 showing apoptosis inducing property through G2/M arrest and mitotic inhibition. Besides, clonogenic assay and wound healing assay demonstrated that the compound could decrease the ability of colony formation and cell migration in a significant way. However, limited availability of the compound impelled us to undertake in silico studies to predictprobable protein targets. This resulted in the identification of IGF1R with highest docking score of −10.0 in preference to four other protein targets (EGFR, AKT1, AKT2, and BCL2) of receptor tyrosine kinase domain (RTKs). As insulin receptor R (Insulin receptor) of tyrosine kinase domain maintains high resemblance with IGF1R, molecular docking was also conducted on the same target. The insignificant docking score suggested specificity of the compound toward IGF1R. Conclusion: The study concluded that; (+)-lyoniresino1-2a-0-β-D-glucopyranoside is a promising apoptosis inducing agent. Molecular modeling of the compound against five crucial protein targets of RTKs suggested that IGF1R could be the probable protein target for the compound.

Simultaneous Separation of Eight Lignans in Forsythia suspensa by β-Cyclodextrin-Modified Capillary Zone Electrophoresis.

The aim of the study was to develop an alternative capillary zone electrophoresis (CZE) for simultaneous determination of phillyrin (1), phillygenin (2), epipinoresinol-4-O-β-glucoside (3), pinoresinol-4-O-β-glucoside (4), lariciresinol (5), pinoresinol (6), isolariciresinol (7) and vladinol D (8) in Forsythia suspensa. The structural types of lignans 1–8 could be attributed to bisepoxylignans (1–4 and 6), monoepoxylignans (5 and 8) and cyclolignan (7). The major difficulties in the CZE separation of 1–8 could be summarization as the simultaneous presence of free lignans (1, 2 and 5–8) and lignan glucosides (3 and 4) and simultaneous occurrence of two pairs of isomers (3 and 4 as well as 5 and 7). Without the addition of β-CD and methanol, the resolution of these analytes was quite poor. However, in this study, compounds 1–8 were excellently separated from each other within 15 min under optimized conditions with a borax running buffer (40 mM borax, pH 10.30) containing 2 mM β-CD and 5% methanol (v/v) at the voltage of 20 kV, temperature of 35 °C and detection wavelength of 234 nm. Validation of the method included tests of linearity, precision, repeatability, stability and accuracy. In addition, the method offered inherent advantages such as lower analytical cost, no need of specific columns and use of small amounts of organic solvents and reagents. Finally, this green and economic CZE was successfully applied for the determination of these bioactive components 1–8 in F. suspensa fruits and its commercial extracts.
