Wedelolactone inhibits human cytomegalovirus replication by targeting distinct steps of the viral replication cycle was written by Svrlanska, Adriana;Ruhland, Anna;Marschall, Manfred;Reuter, Nina;Stamminger, Thomas. And the article was included in Antiviral Research in 2020.Recommanded Product: 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one The following contents are mentioned in the article:

Wedelolactone (WDL) is a coumestan present in the plants Eclipta prostrata and Wedelia calendulacea which are used for treatment of a multitude of health problems in traditional medicine. It has previously been shown that WDL exerts antiviral activity against human immunodeficiency virus and hepatitis C virus. In this study, we investigated the effect of WDL on lytic human cytomegalovirus (HCMV) infection. We demonstrate a strong interference with HCMV replication as analyzed in multi-round replication settings. A more detailed anal. of the underlying mechanisms revealed that WDL acts at two distinct steps of the viral replication cycle. During immediate early (IE) times, we observe an inhibition of IE1/IE2 expression. Although WDL was reported to interfere with NF-κB signaling our results suggest the existence of addnl. mechanisms that impede viral IE expression. During later time points of infection, WDL induced a disruption of the interaction between EZH2 and EED, components of the virus-supportive polycomb repressive complex 2 (PRC2). Thereby, the stability of the PRC2 complex as well as the related complex PRC1 was disturbed leading to diminished viral DNA synthesis. Taken together, we identify WDL as a potent agent against HCMV which interferes at two distinct steps of viral replication. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Recommanded Product: 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one).

Isoflavones are polyphenolic compounds and a class of phytoestrogens naturally present in plants belongs to legume family and also quantified in fruits, vegetables and beverages.Soybean is rich source of isoflavones. Their chem. structure is similar to endogenously available female reproductive hormonal substance estradiol, and cellular targets are estrogen receptors. After bind to the estrogen receptors isoflavones exert estrogenic and antiestrogenic action based upon circulatory levels of estradiol. Cardiovascular diseases are leading cause of death in most of the developing countries and they may occur due to the structural and functional changes in either cardiac muscle or smooth muscle of the vasculature and both. Common cardiac diseases are heart attack, coronary heart disease, hyperlipidemia, angina pectoris, hypertension. Many epidemiol. studies data revealing that consumption of soy protein and soy enriched diet correlate with preventive chances of cardiovascular disease. The United States Food and Drug Administration (USFDA) and other countries declared that everyday consumption of food enriched soy along with low fat may decrease the risk of cardiovascular disease. In this review we attempt the mechanism based cardioprotection of isoflavones in different cardiovascular diseases.

An assessment of dose-dependent UV-B sensitivity in Eclipta alba: Biochemical traits, antioxidative properties, and wedelolactone yield was written by Rai, Kshama;Agrawal, Shashi Bhushan. And the article was included in Environmental Science and Pollution Research in 2021.Name: 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one The following contents are mentioned in the article:

The UV-B-induced signals play a crucial role in improving the analeptic values of medicinally important plants. Eclipta alba L. (Hassak), commonly known as False Daisy, holds supreme stature with its pharmaceutical association in treating various ailments, particularly in Ayurvedic medicine. The present study aimed to evaluate the response of E. alba plants exposed to ambient (AT) and two different supplemental UV-B doses (eUV-B, ambient ±7.2 kJ m-2 day-1), i.e., intermittent (IT) and continuous (CT) UV-B treatment for 130 and 240 h resp. Antioxidative activities and medicinally important compounds (wedelolactone) were measured in different plants parts at three growth stages. Under both the eUV-B treatments, the photosynthetic pigments were adversely affected (along with reductions in protein content) with a concomitant increase in secondary metabolites. Substantial variations in enzymic antioxidants and non-enzymic compounds showed the adaptive resilience strategies of plants against eUV-B. The wedelolactone content increased in leaves but compromised in stem and roots under IT. The results concluded that IT UV-B exposure led to the improvement of plant growth and the yield of wedelolactone compared to CT, suggesting its ameliorative role in improving the test plant’s medicinal value.

IKKα regulates human keratinocyte migration through surveillance of the redox environment was written by Lisse, Thomas S.;Rieger, Sandra. And the article was included in Journal of Cell Science in 2017.Application of 524-12-9 The following contents are mentioned in the article:

Although the functions of H2O2 in epidermal wound repair are conserved throughout evolution, the underlying signaling mechanisms are largely unknown. In this study we used human keratinocytes (HEK001) to investigate H2O2-dependent wound repair mechanisms. Scratch wounding led to H2O2 production in two or three cell layers at the wound margin within âˆ?0 min and subsequent cysteine modification of proteins via sulfenylation. Intriguingly, exogenous H2O2 treatment resulted in preferential sulfenylation of keratinocytes that adopted a migratory phenotype and detached from neighboring cells, suggesting that one of the primary functions of H2O2 is to stimulate signaling factors involved in cell migration. Based on previous findings that revealed epidermal growth factor receptor (EGFR) involvement in H2O2-dependent cell migration, we analyzed oxidation of a candidate upstream target, the inhibitor of κB kinase α (IKKα; encoded by CHUK), as a mechanism of action. We show that IKKα is sulfenylated at a conserved cysteine residue in the kinase domain, which correlates with de-repression of EGF promoter activity and increased EGF expression. Thus, this indicates that IKKα promotes migration through dynamic interactions with the EGF promoter depending on the redox state within cells.

Enhancement of skin anti-inflammatory activities of Eclipta prostrata L. from the ultrasonic extraction process was written by Lee, Hyeon Yong. And the article was included in Applied Sciences in 2017.Electric Literature of C16H10O7 The following contents are mentioned in the article:

This work first showed that the skin anti-inflammatory activities of Eclipta prostrata L. (E. prostrata L.)n be increased through an ultrasonic extraction process at a frequency of 120 kHz with 70% ethanol at 40 °C for 6 h. The extract from the ultrasound extraction (UE) contained 378.6 mg/100 g of wedelolactone (a major bioactive substance in E. prostrata L.), compared with the 172.9 mg/100 g from a conventional extraction process with 70% ethanol at 80 °C for 12 h (EE). The UE showed less than 10% of low cytotoxicity against normal fibroblast cells, and also exhibited much higher antioxidant activities than that from the EE when treating with 0.3 mg/mL of the extracts It was proved that the high antioxidant activities of the UE were closely correlated with the enhancement of skin anti-inflammatory activities by effectively suppressing the production of tumor necrosis factor-alpha and interleukin-6 from macrophages. The production of prostaglandin E2 from human skin cells was also greatly reduced, compared with the EE for all ranges of the treatments. These results strongly indicate that the various biol. activities of E. prostrata L. can be improved by a simple ultrasound extraction process because of the high elution of bioactive substances even at a low temperature This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Electric Literature of C16H10O7).

Wedelolactone acts as proteasome inhibitor in breast cancer cells was written by Nehybova, Tereza;Smarda, Jan;Daniel, Lukas;Stiborek, Marek;Kanicky, Viktor;Spasojevic, Ivan;Preisler, Jan;Damborsky, Jiri;Benes, Petr. And the article was included in International Journal of Molecular Sciences in 2017.Computed Properties of C16H10O7 The following contents are mentioned in the article:

Wedelolactone is a multi-target natural plant coumestan exhibiting cytotoxicity towards cancer cells. Although several mol. targets of wedelolactone have been recognized, the mol. mechanism of its cytotoxicity has not yet been elucidated. In this study, we show that wedelolactone acts as an inhibitor of chymotrypsin-like, trypsin-like, and caspase-like activities of proteasome in breast cancer cells. The proteasome inhibitory effect of wedelolactone was documented by (i) reduced cleavage of fluorogenic proteasome substrates; (ii) accumulation of polyubiquitinated proteins and proteins with rapid turnover in tumor cells; and (iii) mol. docking of wedelolactone into the active sites of proteasome catalytic subunits. Inhibition of proteasome by wedelolactone was independent on its ability to induce reactive oxygen species production by redox cycling with copper ions, suggesting that wedelolactone acts as copper-independent proteasome inhibitor. We conclude that the cytotoxicity of wedelolactone to breast cancer cells is partially mediated by targeting proteasomal protein degradation pathway. Understanding the structural basis for inhibitory mode of wedelolactone might help to open up new avenues for design of novel compounds efficiently inhibiting cancer cells.

High-Throughput Screening at the Membrane Interface Reveals Inhibitors of Amyloid-β was written by Cox, Sarah J.;Lam, Brian;Prasad, Ajay;Marietta, Hannah A.;Stander, Nicholas V.;Joel, Joseph G.;Sahoo, Bikash R.;Guo, Fucheng;Stoddard, Andrea K.;Ivanova, Magdalena I.;Ramamoorthy, Ayyalusamy. And the article was included in Biochemistry in 2020.Formula: C16H10O7 The following contents are mentioned in the article:

Aggregation and the formation of oligomeric intermediates of amyloid-β (Aβ) at the membrane interface of neuronal cells are implicated in the cellular toxicity and pathol. of Alzheimer’s disease. Small mol. compounds have been shown to suppress amyloid aggregation and cellular toxicity, but often the presence of a lipid membrane negates their activity. A high-throughput screen of 1800 small mols. was performed to search for membrane active inhibitors, and 21 primary hits were discovered. Through the use of fluorescence-based assays, transmission electron microscopy, and dot blot assays, the initial 21 primary hits were narrowed down to five lead compounds NMR and CD experiments were used for further confirmation of amyloid inhibition at the membrane interface and to obtain insights into the secondary structure of amyloid-β, while size exclusion chromatog. was used to characterize the size of Aβ species. Lastly, dye-leakage assays allowed us to understand how the addition of the five lead compounds affected amyloid-β’s ability to permeate the lipid bilayer. These results provide insights into small mols. that stabilize small amyloid species in the presence of membranes for the development of tool compounds for deeper investigations of these transient species.

Honey is a traditional natural medicine constantly revisited as an anticancer agent administered alone and in combination. Chemotherapy with cytotoxic agents decrease the quality of life of patients. Hence, the need of studies on complementary and alternative medicine to improve therapeutic outcomes, as investigated here for honey. The human ovarian cancer model based on MTT tetrazolium salt colorimetric assay was used to determine cytotoxicity of three types of pot-honey produced by Ecuadorian stingless bees known with ethnic names “abeja de tierra”, “catiana” and “bunga negra” corresponding to Geotrigona leucogastra, Scaptotrigona sp and Melipona grandis. The honeys were characterized for their antioxidant activity measured with three methods, flavonoid, polyphenols and protein contents. The Melipona grandis pot-honey was the most active with IC₅₀ value of 0.15 mg mL^-1 for the A2780, and also in overcoming cisplatin resistance with a remarkably low IC₅₀ 0.05 mg mL^-1 for the A2780^cisR, and a resistance factor of 0.32. This pot-honey demonstrated a distinctive characteristic illustrated by a wide reduction of the IC₅₀ value in the cisplatin resistant A2780^cisR cell line.

Protective effects of wedelolactone on dextran sodium sulfate induced murine colitis partly through inhibiting the NLRP3 inflammasome activation via AMPK signaling was written by Wei, Wencheng;Ding, Meiling;Zhou, Kai;Xie, Haifeng;Zhang, Mian;Zhang, Chaofeng. And the article was included in Biomedicine & Pharmacotherapy in 2017.COA of Formula: C16H10O7 The following contents are mentioned in the article:

It has been reported that the ethanol extract of Wedelia chinensis attenuates murine colitis. Wedelolactone (WEL), a coumestane-type compound with many pharmacol. activities, was isolated from W. chinensis. The present study aims to investigate the beneficial effects and underlying mechanisms of WEL on ulcerative colitis. In a dextran sodium sulfate (DSS)-induced mouse model, oral administration of WEL (50 mg/kg) significantly attenuated pathol. colonic damage and inhibited inflammatory infiltration, myeloperoxidase and alk. phosphatase activities through MAPKs and NF-κB signaling pathways, while activating AMPK in colons treated with DSS. Further study revealed that WEL treatment dramatically inhibited NLRP3 inflammasome activation and caspase-1 phosphorylation to decrease IL-1β release in colons treated with DSS. In addition, WEL effectively regulates the disorder of skeleton proteins in colonic epithelial cells NCM460 exposed to TNF-α and protects the intestinal barrier function by activating AMPK in vivo. In summary, the AMPK-NLRP3-IL-1β signaling axis plays an important role in colitis following WEL treatments. These findings provide new insights into the pharmacol. actions of WEL as a potential therapeutic agent for colitis.
