Wedelolactone, an anti-inflammatory botanical, interrupts c-Myc oncogenic signaling and synergizes with enzalutamide to induce apoptosis in prostate cancer cells was written by Sarveswaran, Sivalokanathan;Ghosh, Ritisha;Parikh, Rujul;Ghosh, Jagadananda.

The c-Myc gene encodes an oncoprotein transcription factor that is frequently upregulated in almost all cancer types and is the subject of intense investigation for management of cancer because of its pleiotropic effects controlling a spectrum of cellular functions. However, due of its nonenzymic nature, development of suitable strategies to block its protein-protein or protein-DNA interaction is challenging. Thus, c-Myc has been recognized as an elusive mol. target for cancer control, and various approaches are in development to inhibit c-Myc transcriptional activity. We observed that wedelolactone (WDL), an anti-inflammatory botanical compound, severely downregulates the expression of c-Myc mRNA in prostate cancer cells. Moreover, WDL dramatically decreases the protein level, nuclear accumulation, DNA-binding, and transcriptional activities of c-Myc. c-Myc is a transforming oncogene widely expressed in prostate cancer cells and is critical for maintaining their transformed phenotype. Interestingly, WDL was found to strongly affect the viability of Myc-activated prostate cancer cells and completely block their invasion as well as soft agar colony formation in vitro. WDL was also found to downregulate c-Myc in vivo in nude mice xenografts. Moreover, WDL synergizes with enzalutamide to decrease the viability of androgen-sensitive prostate cancer cells via induction of apoptosis. These findings reveal a novel anticancer mechanism of the natural compound WDL, and suggest that the oncogenic function of c-Myc in prostate cancer cells can be effectively downregulated by WDL for the development of a new therapeutic strategy against Myc-driven prostate cancer.

The mechanism of Arhalofenate in alleviating hyperuricemia-Activating PPARγ thereby reducing caspase-1 activity was written by Wang, Guihong;Zuo, Ting;Li, Ran. And the article was included in Drug Development Research in 2020.Product Details of 524-12-9 The following contents are mentioned in the article:

Hyperuricemia (HUA) is an important risk factor for renal diseases and contributes to gout. Arhalofenate (Arha) has been proved to have uricosuric activity as an inhibitor of URAT1, organic anion transporter 4 (OAT4) and OAT10. However, the effects of Arha on HUA remain unknown. The objective of this study was to investigate whether Arha could alleviate HUA and uncovered the underlying mechanism in vitro. HK-2 cells were exposed to uric acid (UA) to simulate HUA in vitro. Then cells were treated with Arha, caspase-1 inhibitor Belnacasan (Beln), caspase-11 inhibitor Wedelolactone (Wede) and PPARγ inhibitor Mifobate, resp. The alteration of cell proliferation, inflammation, pyroptosis and expression of related proteins were detected. Results showed that UA exposure inhibited cell viability and increased IL-1β and IL-18 generation in a concentration dependent manner. Meanwhile, UA activated the cleavage of gasdermin D (GSDMD), enhanced the protein expression of URAT1, OAT4, TLR4, caspase-1, and caspase-11 and reduced PPARγ expression. While the presence of Arha or Beln enhanced cell viability and inhibited cleavage of GSDMD. Wede slightly increased cell viability but failed to prevent GSDMD cleavage. The expression of related proteins except caspase-11 was also recovered by Arha. Beln and Wede partially rescued related proteins level except PPARγ compared with model group. Besides, the co-treatment of Mifobate blunted the effects of Arha on cell viability and expression of GSDMD, TLR4, and caspase-1. In conclusion, Arha inhibited UA transport as well as preventing inflammation and pyroptosis via activating PPARγ thereby blocking caspase-1 activation of HUA in vitro.

Anti-cancer effects of wedelolactone: interactions with copper and subcellular localization was written by Kucirkova, Tereza;Stiborek, Marek;Ducka, Monika;Navratilova, Jarmila;Bogdanovic Pristov, Jelena;Popovic-Bijelic, Ana;Vojvodic, Snezana;Preisler, Jan;Kanicky, Viktor;Smarda, Jan;Spasojevic, Ivan;Benes, Petr. And the article was included in Metallomics in 2018.Application of 524-12-9 The following contents are mentioned in the article:

Wedelactone (WL), a plant polyphenolic derivative of coumestan, represents a promising anti-cancer agent. The underlying mechanisms of its action are not fully understood and appear to involve interplay with copper ions. This study examined coordination and redox interactions of WL with Cu²⁺ in phosphate buffer (pH 7), and in two breast cancer cell lines. EPR, UV-Vis and fluorescence spectroscopy showed that WL and Cu²⁺ build a coordination complex with 2 : 1 stoichiometry and distorted tetrahedral geometry. WL showed strong fluorescence that was quenched by Cu²⁺. The sequestration of the intracellular copper pool with neocuproine led to a significant drop in the cytotoxic effects of WL, whereas the co-application of Cu²⁺ and WL and the formation of an extracellular complex suppressed both the cytotoxic effects of WL and copper loading. Fluorescence microscopy showed that WL is mainly localized in the cytosol and significantly less in the nuclei. WL fluorescence was stronger in cells pretreated with neocuproine, implying that the complex of WL and Cu²⁺ is formed inside the cells. WL caused a two-fold increase in the lysosomal level of copper as well as copper-dependent lysosome membrane permeabilization. On the other hand, the protective effects of overexpression of thioredoxin 1 imply that WL exerts the main oxidative impact inside the nucleus. The interactions of WL with copper may be essential for therapeutic performance and selectivity against cancer cells, taking into account that a number of cancer types, including breast cancer, exhibit increased intratumoral copper levels or altered copper distribution. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Application of 524-12-9).

Wedelolactone alleviates acute pancreatitis and associated lung injury via GPX4 mediated suppression of pyroptosis and ferroptosis was written by Fan, Rong;Sui, Jidong;Dong, Xuepeng;Jing, Biao;Gao, Zhenming. And the article was included in Free Radical Biology & Medicine 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:

Acute pancreatitis (AP) is an inflammatory disorder associated with multiple organ failure. Pyroptosis and ferroptosis are two newly recognized cell death, and whether pyroptosis and ferroptosis are involved in AP remain largely elusive. The nature compound Wedelolactone (Wed) exhibits strong anti-inflammatory and antioxidant activities, the present study aims to investigate the effect of Wed on AP and unravel whether Wed could protect against AP and relevant lung injury against pyroptosis and ferroptosis. Our results showed that the pyroptosis inhibitor disulfiram or ferroptosis inhibitor ferrostatin-1 significantly alleviated AP and associated lung injury in the taurocholate or caerulein-induced murine AP model. Administration with Wed ameliorated AP and lung injury as evidenced by improved pathol. injuries, reduced serum pancreatic digestive enzymes, and proinflammatory cytokines. The in vivo and in vitro data demonstrated that Wed broadly inhibited caspase1/caspase11 activation, reduced mature interleukin-1β (IL-1β) and N-terminal domain of gasdermin D (GSDMD-N) level. The oxidative stress and lipid peroxidation were also suppressed along with the up-regulation of the ferroptosis antagonism marker glutathione peroxidase-4 (GPX4) in Wed treatment group. Wed promoted the transcriptional activity and the selenium sensitivity of GPX4. Moreover, the protective effects of Wed in caerulein-stimulated pancreatic acinar cells were markedly abrogated by the down-regulation of GPX4. Collectively, our data suggest that pyroptosis and ferroptosis play crucial roles in AP. Wed mitigated AP and associated lung injury via GPX4 mediated suppression of pyroptosis and ferroptosis.

AIMS AND OBJECTIVE: Wedelolactone and demethylwedelolactone are the two major coumarin constituents of Herba Ecliptae. The objective of this work was to develop and validate a sensitive, rapid, and robust UPLC-MS/MS method for the simultaneous quantification of wedelolactone and demethylwedelolactone in rat plasma. MATERIALS AND METHODS: Wedelolactone and demethylwedelolactone were extracted from rat plasma by protein precipitation with acetonitrile. Electrospray ionization in negative mode and selected reaction monitoring (SRM) were used for wedelolactone and demethylwedelolactone at the transitions m/z 312.8â†?98.0 and m/z 299.1â†?70.6, respectively. Chromatographic separation was conducted on a Venusil C₁₈ column (50 mm × 2.1 mm, 5 μm) with isocratic elution of acetonitrile-0.1% formic acid in water (55:45, v/v) at a flow rate of 0.3 mL/min. A linear range was observed over the concentration range of 0.25-100 ng/mL for wedelolactone and demethylwedelolactone. RESULTS: They reached their maximum plasma concentrations (C_max, 74.9±13.4 ng/mL for wedelolactone and 41.3±9.57 ng/mL for demethylwedelolactone) at the peak time (T_max) of 0.633 h and 0.800 h, respectively. The AUC_0-t value of wedelolactone (260.8±141.8 ng h/mL) was higher than that of demethylwedelolactone (127.4±52.7 ng h/mL) by approximately 2-fold, whereas the terminal elimination half-life (t_1/2) of wedelolactone (2.20±0.59 h) showed the approximately same as that of demethylwedelolactone (2.08±0.69 h). CONCLUSION: Based on full validation according to US FDA guidelines, this UPLC-MS/MS method was successfully applied to a pharmacokinetic study in rats.

A practical and reliable method for in vitro tetraploidization of Sphagneticola calendulacea (L.) Pruski [synonym Wedelia chinensis (Osbeck) Merrill] has been established to enhance the production of wedelolactone. Shoot tip and nodal explants from in vitro-grown culture (2n = 50) were exposed to the antimitotic chem., i.e., colchicine, at various concentrations (0, 0.025, 0.05, 0.1, 0.3, and 0.5%; w/v) for 12, 24, 36, 48, and 60 h. The treated explants were then incubated and proliferated on Murashige and Skoog (MS) medium fortified with 0.2 mg l^-1 thidiazuron and 0.05 mg l^-1 naphthalene acetic acid, followed by root induction in 1.0 mg l^-1 indole-3 acetic acid enriched 1/2MS medium. Treatment of shoot tips with 0.05% colchicine for 24 h supported the maximum rate of survival (63.33%) of explants as well as tetraploid induction (42.93%). Morphol., stomatal, and cytol. characteristics along with the secondary metabolite content of the in vitro tetraploids were compared to that of diploids. The recovered tetraploid plants possessed superior plant height, stem diameter, leaf size, root number, and increased length and width of stomata but decreased stomatal frequency. The tetraploid plants demonstrated twice the chromosome number (2n = 4x = 100) than the diploids as confirmed through cytol., spectrophotometry and flow cytometry. High-performance thin-layer chromatog. showed a significant enhancement in the wedelolactone content of tetraploid plants (541.48μg g^-1 of dried sample) in comparison to diploid plants (325.43μg g^-1 of dried sample), signifying the prospective of this technique for the trade value improvement.

Objectives : Wedelolactone exhibits regulatory effects on some inflammatory diseases. However, the anti-inflammatory mechanism of wedelolactone has not been entirely unravelled. Therefore, the present study focuses on investigating the mechanism of wedelolactone on NLRP3 inflammasome in macrophages and its influence on MSU-induced inflammation. Materials and Methods : BMDM, J774A.1 and PMA-differentiated THP-1 macrophages were primed with LPS and then stimulated with ATP or nigericin or MSU crystal in the presence or absence of wedelolactone. The cell lysates and supernatants were collected to detect NLRP3 inflammasome components such as NLRP3, ASC and caspase 1, as well as pyroptosis and IL-1β production In addition, the anti-inflammatory effects of wedelolactone on MSU-induced peritonitis and arthritis mice were also evaluated. Results : We found that wedelolactone broadly inhibited NLRP3 inflammasome activation and pyroptosis and IL-1β secretion. Wedelolactone also block ASC oligomerization and speck formation. The inhibitory effects of wedelolactone were abrogated by PKA inhibitor H89, which also attenuated wedelolactone-enhanced Ser/Thr phosphorylation of NLRP3 at PKA-specific sites. Importantly, wedelolactone could abate MSU-induced IL-1β production and neutrophils migration into peritoneal cavity, and reduced caspase 1 (p20) and IL-1β expression in the joint tissue of MSU-induced arthritis. Conclusion : Our results indicate that wedelolactone promotes the Ser/Thr phosphorylation of NLRP3 to inhibit inflammasome activation and pyroptosis partly through potentiating PKA signalling, thus identifying its potential use for treating MSU-induced peritonitis and gouty arthritis.

Olive oil polyphenols, which possess cytoprotective activities like anti-oxidant and anti-inflammatory effects, could modulate osteoblast functions. The aim of this study is to elucidate the effects and the underlying mechanisms of hydroxytyrosol and oleuropein on the tumor necrosis factor-α (TNF-α)-induced macrophage colony-stimulating factor (M-CSF) and interleukin-6 (IL-6) synthesis in osteoblasts. Osteoblast-like MC3T3-E1 cells were pretreated with hydroxytyrosol, oleuropein, deguelin, PD98059 or wedelolactone, and then stimulated by TNF-α. The levels of M-CSF and IL-6 in the conditioned medium were determined with ELISA. The mRNA expression levels of M-CSF or IL-6 were determined with real-time RT-PCR. The phosphorylation levels of Akt, p44/p42 mitogen-activated protein (MAP) kinase or NF-κB in the cell lysates were determined with Western blot anal. Hydroxytyrosol and oleuropein attenuated the TNF-α-stimulated M-CSF release. Deguelin, an inhibitor of Akt, significantly suppressed the TNF-α-stimulated M-CSF release, which failed to be affected by the MEK1/2 inhibitor PD98059 or the IκB inhibitor wedelolactone. Hydroxytyrosol and oleuropein suppressed the TNF-α-induced phosphorylation of Akt and p44/p42 MAP kinase. Hydroxytyrosol and oleuropein attenuated the TNF-α-stimulated IL-6 release. Hydroxytyrosol suppressed the TNF-α-induced mRNA expressions of M-CSF and IL-6. Hydroxytyrosol or oleuropein failed to affect the cell viability. Our present findings strongly suggest that olive oil polyphenols hydroxytyrosol and oleuropein down-regulates TNF-α signaling at the points upstream of Akt and p44/p42 MAP kinase in osteoblasts, leading to the attenuation of M-CSF and IL-6 synthesis.

Environmental pollutant N-N’ethylnitrosourea-induced leukemic NLRP3 inflammasome activation and its amelioration by Eclipta prostrata and its active compound wedelolactone was written by Bhattacharyya, Subhashree;Law, Sujata. And the article was included in Environmental Toxicology in 2022.Reference of 524-12-9 The following contents are mentioned in the article:

Environmental exposure of N-nitroso compounds (NOCs) from various sources like tobacco smoke, pesticides, smoked meat, and rubber manufacturing industries has been an alarming cause of carcinogenesis. Neonatal exposure to the carcinogenic N-N’ethylnitrosourea (ENU), a NOC has been established to cause leukemogenesis. Our world is constantly battling against cancer with consistent investigations of new anti-cancer therapeutics. Plant derived compounds have grasped worldwide attention of researchers for their promising anti-cancer potentials. Eclipta prostrata is one such ayurvedic herb, renowned for its anti-inflammatory properties. Currently, it has been explored in various cancer cell lines to establish its anti-cancer effect, but rarely in in-vivo cancer models. Wedelolactone (WDL), the major coumestan of E. prostrata is recognized as an inhibitor of IKK, a master regulator of the NF-kB inflammatory pathway. As persistent inflammation and activated inflammasome contribute to leukemogenesis, we tried to observe anti-leukemogenic efficacy of E. prostrata and its active compound WDL on the marrow cells of ENU induced exptl. leukemic mice. Treatment groups were administered an oral gavage at a dose of 1200 mg/kg and 50 mg/kg b.w of crude extract and WDL resp. for 4 wk. Various parameters like hemogram, survivability, cytol. and histol. investigations, migration assay, cell culture, flowcytometry and confocal microscopy were taken into consideration pre- and post-treatment. Interestingly, the plant concoction portrayed maximum effects in comparison to WDL alone. The study suggests E. prostrata and WDL as vital complementary adjuncts for anti-inflammasome mechanism in ENU-induced leukemia.
