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.

Wedelolactone protects against cisplatin-induced nephrotoxicity in mice via inhibition of organic cation transporter 2 was written by Wang, Guangju;Bi, Yajuan;Xiong, Hui;Bo, Tongwei;Han, Lifeng;Zhou, Lijun;Zhang, Chunze;Zhang, Youcai. And the article was included in Human & Experimental Toxicology in 2021.COA of Formula: C16H10O7 The following contents are mentioned in the article:

The balance of cisplatin uptake and efflux, mediated mainly by organic cation transporter 2 (OCT2) and multidrug and toxin extrusion 1 (MATE1), resp., determines the renal accumulation and nephrotoxicity of cisplatin. Using transporter-mediated cellular uptake assay, we identified wedelolactone (WEL), a medicinal plant-derived natural compound, is a competitive inhibitor of OCT2 and a noncompetitive inhibitor of MATE1. Wedelolactone showed a selectivity to inhibit OCT2 rather than MATE1. Cytotoxicity studies revealed that wedelolactone alleviated cisplatin-induced cytotoxicity in OCT2-overexpressing HEK293 cells, whereas it did not alter the cytotoxicity of cisplatin in various cancer cell lines. Addnl., wedelolactone altered cisplatin pharmacokinetics, reduced kidney accumulation of cisplatin, and ameliorated cisplatin-induced acute kidney injury in the Institute of Cancer Research mice. In conclusion, these findings suggest a translational potential of WEL as a natural therapy for preventing cisplatin-induced nephrotoxicity and highlight the need for drug-drug interaction investigations of WEL with other treatments which are substrates of OCT2 and/or MATE1.

Wedelolactone is known to have biol. activities such as anti-inflammation hepatitis, anti-hepatotoxic activity, and trypsin inhibitory effect. However, up to date, there has not been any deep study on the role of wedelolactone for zymosan-induced signaling pathways in the process of regulating the excessive inflammatory responses in host. Here, we demonstrated that wedelolactone plays an essential role for regulation of zymosan-induced inflammatory responses in murine bone marrow-derived macrophages (BMDMs). The zymosan-mediated secretion of tumor necrosis factor-α (TNF)-α, interleukin (IL)-6, and IL12p40 but not IL-10 in BMDMs was significantly inhibited by pre-treatment with wedelolactone (30 μg/mL, P < 0.001). Furthermore, zymosan-induced supreoxide generation, NADPH oxidase (P < 0.001), phosphorylation of p47phox in BMDMs were significantly reduced by pre-treatment of wedelolactone (30 μg/mL). Collectively, these data indicated that wedelolactone reduced zymosan-induced inflammatory responses. Moreover, in-vivo wedelolactone (30 mg/kg) was significantly rescued from zymosan-induced shock through inhibition of systemic inflammatory cytokine levels.

Altered glucose-6-phosphate dehydrogenase (G6PD) status is influential in many cellular pathophysiol. processes and diseases, making G6PD a potential target for cancer therapy. However, the available G6PD inhibitors are very limited and restricted. Here we developed a reducing equivalent NADP (NADPH) absorption photometry assay based on enzyme kinetics to characterize G6PD activity. In this way, we performed a high-throughput screening (HTS) to an in house library. And then we identified compound named Wedelolactone inhibiting G6PD strongly in a non-competitive, reversible way. In addition, we did the surface Plasmon Resonance (SPR) assay and indicated the KD between Wedelolactone and G6PD protein was 3.64μM. Furthermore, our basic colony formation assay showed the inhibitory effect of Wedelolactone on the proliferation of ovarian cancer cells (IC50 âˆ?10μM). Thus, we provided a high-throughput screening assay to quickly and efficiently discover G6PD inhibitors, and identified Wedelolactone as a G6PD inhibitor, implying that Wedelolactone suppresses ovarian cancer partly through targeting G6PD.
