The quant. anal. of multiple indexes remains an important quality evaluation method of traditional Chinese medicine (TCM) herbal formulas. The Chinese Pharmacopoeia 2015 only stipulates the content of a single component, specnuezhenide, in Erzhiwan composed of the Fructus Ligustri Lucidi (FLL) powder and aqueous extracts of Herba Ecliptae (HE). To generalize the intrinsic quality of Erzhiwan, a novel C30-HPLC method with good precision, accuracy, and reproducibility was developed for the simultaneous determination of six compounds, including two isomers, and then an analytic hierarchy process was further applied to integrate and discriminate the quality of four samples prepared via different methods. The results of the anal. were in agreement with the antioxidant tests in vitro. This comprehensive strategy could provide a reference and suggestions for the improvement of the quality evaluation method of TCM herbal formulas. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Related Products of 524-12-9).

Multiwalled carbon nanotube based screen printed sensor was fabricated and utilized for the cyclic voltammetric (CV) study of a phytoconstituent wedelolactone (WDL). The analyte system was studied with Britton Robinson buffer as the supporting electrolyte. Square wave voltammetry (SWV) technique was performed for the optimization of the pH, where the pH (2.5) of the system was optimized for further investigation of the analyte system. Multiwalled carbon nanotube modified screen printed electrode (M-SPE) offered high sensitivity towards WDL as compared to the bare screen printed electrode (SPE). Voltammetric studies with M-SPE revealed the oxidation of WDL with two oxidation peaks (a1 and a2) with Ea1 = 0.08V and Ea2 =0.5 V with scan rate varying from 10-120 mV/s and exhibits diffusion-controlled process.

And the article was included in Chemicke Listy in 2016.Category: benzofurans The following contents are mentioned in the article:

All the three types of natural dyes under investigation – direct, vat and mordant – were extracted by a solvent mixture containing methanol, dichloromethane, and formic acid in a ratio of 70:25:5. For the identification, highresoln. mass spectrometry (HR-LC-MS) was used. The best results were achieved using neg. electrospray ionization. In medieval textiles exploration from the New Town of Prague, dyestuffs from madder, woad, crimson coccids, weld, buckthorn, brazilwood, and tannins from oak galls were found. HR-LC-MS analyses confirmed the usage of various combinations of dyestuffs leading to the formation of new types of colors. The most frequent combinations were the fusion of red madder with blue woad, as well as combinations of madder with yellow weld and madder with crimson coccids.

Formulation of wedelolactone enriched extract with enhanced potential to inhibit cytokines in experimental arthritis was written by Atre, B. N.;Arulmozhi, S.;Sathiyanarayanan, L.;Dhapte-Pawar, V. V.;Mahadik, K. R.. And the article was included in International Journal of Research in Pharmaceutical Sciences in 2021.Application In Synthesis of 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one The following contents are mentioned in the article:

Eclipta alba Linn. (Asteraceae) is traditionally claimed and reported to possess antarthritic and anti-inflammatory activity. Wedelolactone, an active constituent of Eclipta alba Linn responsible for its therapeutic effectiveness, is poorly water soluble and less bioavailable. Hence in the present study, we proposed a SNEDDS formulation of wedelolactone rich extracts of Eclipta alba Linn. (EAF) and evaluated its effect in Freund’s complete adjuvant (FCA) induced arthritis in rats. EAF reduced increase in paw volume and hyperalgesia in 50, 100 and 200 mg/kg doses significantly. It restored all cytokines (Tumor Necrosis Factor- α , Interleukin-1β and Interleukin-6); hematol. and biochem. parameters altered due to FCA induction. The histopathol. further supported the potential of EAF in arresting the progress of the disease. It protected cartilage destruction and exudation of inflammatory cells dose dependently. In conclusion, the EAF exhibited potent antarthritic potential due to the increased bioavailability of wedelolactone and other constituents. The mechanism of action is mainly mediated through inhibition of cytokines, anti-inflammatory and antioxidant potential of wedelolactone.

Wedelolactone mitigates UVB induced oxidative stress, inflammation and early tumor promotion events in murine skin: plausible role of NFkB pathway was written by Ali, Farrah;Khan, Bilal Azhar;Sultana, Sarwat. And the article was included in European Journal of Pharmacology in 2016.Category: benzofurans The following contents are mentioned in the article:

UVB (Ultra-violet B) radiation is one of the major etiol. factors in various dermal pathol. viz. dermatitis, actinic folliculitis, solar urticaria, psoriasis and cancer among many others. UVB causes toxic manifestation in tissues by inciting inflammatory and tumor promoting events. We have designed this study to assess the anti-inflammatory and anti-tumor promotion effect of Wedelolactone (WDL) a specific IKK inhibitor. Results indicate significant restoration of anti-oxidative enzymes due to WDL treatments. We also found that WDL was effective in mitigating inflammatory markers consisting of MPO (myeloperoxidase), Mast cells trafficking, Langerhans cells suppression and COX 2 expression up regulation due to UVB exposure. We also deduce that WDL presented a promising intervention in attenuating early tumor promotion events caused by UVB exposure as indicated by the results of ODC (Ornithine Decarboxylase), Thymidine assay, Vimentin and VEGF (Vascular-endothelial growth factor) expression. This study was able to provide substantial cues for the therapeutic ability of Wedelolactone against inflammatory and tumor promoting events in murine skin depicting plausible role of NFkB pathway.

Wedelolactone targets EZH2-mediated histone H3K27 methylation in mantle cell lymphoma was written by Romanchikova, Nadezhda;Trapencieris, Peteris. And the article was included in Anticancer Research in 2019.Synthetic Route of C16H10O7 The following contents are mentioned in the article:

Background/Aim: Enhancer of zeste homolog 2 (EZH2), the catalytic subunit of polycomb repressive complex 2 (PRC2), possesses histone N-methyltransferase (HMT) activity and plays an essential role in cancer initiation and development. The aim of the present study was to investigate the potential of Wedelolactone (WL) to inhibit the methylation activity of EZH2. Materials and Methods: The mantle cell lymphoma (MCL) cell line, Mino, was treated with WL, while untreated cells were used as control. HMT activity and EZH2 amount were measured in nuclear extracts from WL-treated and control Mino cells. Results: WL was found to target EZH2-mediated histone H3K27 methylation. Along with the inhibition of H3K27 methylation in vitro (IC50 = 0.3μM), WL suppressed HMT activity in Mino cells with an IC50 value of 3.2μM. We detected a reduced amount of EZH2 in Mino cells treated with WL, compared to untreated control cells. Conclusion: This is the first study to show that WL induces inhibition of H3K27 methylation via EZH2 modulation and decreases cell proliferation in MCL, in vitro. WL is proposed as a promising agent and a novel epigenetic approach in MCL investigation and treatment.
