Wedelolactone is a coumarin ether with significant hepatoprotective effects. However, there are few pharmacokinetic studies of wedelolactone, which will affect the studies of its efficacy and potential toxicity. In this study, a selective ultra-performance liquid chromatog. (UPLC) method was developed to confirm the pharmacokinetic parameters of wedelolactone in rat plasma. The chromatog. separation was carried out on a Kromasil C18 UPLC column (250 × 4.6 mm; 5.0 mum) by gradient mobile phase of methanol-water containing 0.5% acetic acid (volume/volume). Perfect linearity was obtained and the samples were stable under different conditions. The intra-day and inter-day precisions (relative standard deviation, %) were within 3.81% and accuracies (relative error, %) ranged from -4.01% to 7.12%. The extraction recoveries in rat plasma ranged from 95.98% to 108.93%. This rapid method was successfully applied in the pharmacokinetic study of wedelolactone in rat plasma. Following the oral administration of 5.00 mg/kg wedelolactone, the wedelolactone was rapidly absorbed. Pharmacokinetic parameters were used to quant. describe the dynamic changes of wedelolactone in vivo, providing a theor. basis for pharmacol. research on drugs and preclin. medication. The study of wedelolactone can provide a theor. basis and quick anal. for the study of other traditional Chinese medicine. 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).

Caspase-1 Specific Light-Up Probe with Aggregation-Induced Emission Characteristics for Inhibitor Screening of Coumarin-Originated Natural Products was written by Lin, Hao;Yang, Haitao;Huang, Shuai;Wang, Fujia;Wang, Dong-Mei;Liu, Bin;Tang, Yi-Da;Zhang, Chong-Jing.

Caspase-1 is a key player in pyroptosis and inflammation. Caspase-1 inhibition is found to be beneficial to various diseases. Coumarin-originated natural products have an anti-inflammation function, but their direct inhibition effect to caspase-1 remains unexplored. To evaluate their interactions, the widely used com. coumarin-based probe (Ac-YVAD-AMC) is not suitable, as the background signal from coumarin-originated natural products could interfere with the screening results. Therefore, fluorescent probes using a large Stokes shift could help solve this problem. In this work, we chose the fluorophore of tetraphenylethylene-thiophene (TPETH) with aggregation-induced emission characteristics and a large Stokes shift of about 200 nm to develop a mol. probe. Bioconjugation between TPETH and hydrophilic peptides (DDYVADC) through a thiol-ene reaction generated a light-up probe, C1-P3. The probe has little background signal in aqueous media and exerts a fluorescent turn-on effect in the presence of caspase-1. Moreover, when evaluating the inhibition potency of coumarin-originated natural products, the new probe could generate a true and objective result but not for the com. probe (Ac-YVAD-AMC), which is evidenced by HPLC anal. The quick light-up response and accurate screening results make C1-P3 very useful in fundamental study and inhibitor screening toward caspase-1. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Formula: C16H10O7).

Wedelolactone improves the renal injury induced by lipopolysaccharide in HK-2 cells by upregulation of protein tyrosine phosphatase non-receptor type 2 was written by Zhi, Deyuan;Zhang, Meng;Lin, Jin;Liu, Pei;Wang, Yajun;Duan, Meili. And the article was included in Journal of International Medical Research in 2021.Synthetic Route of C16H10O7 The following contents are mentioned in the article:

To explore the effects of wedelolactone (WEL) on sepsis-induced renal injury in the human renal proximal tubular epithelial cell line HK-2. HK-2 cells were stimulated by 1μg/mL lipopolysaccharide (LPS) to trigger renal injury in vitro. HK-2 cells were pretreated with or without WEL (0.1, 1 and 10μM) before LPS stimulation. Protein and mRNA analyses were performed using enzyme-linked immunosorbent assays, Western blot anal. and quant. reverse transcription-polymerase chain reaction. The MTT assay and flow cytometry were used to measure cell viability and the rate of cell apoptosis. Protein tyrosine phosphatase non-receptor type 2 (PTPN2) knockdown was induced by the transection of HK-2 cells with short hairpin RNA. Cell viability was significantly increased in a dose-dependent manner by WEL in LPS-induced HK-2 cells. WEL also decreased the levels of four inflammatory cytokines and cell apoptosis in LPS-induced HK-2 cells. The level of PTPN2 was increased after WEL treatment. PTPN2 knockdown partly abolished the inhibitory effects of WEL on cell apoptosis, the levels of inflammatory cytokines and on p38 mitogen-activated protein kinase/nuclear factor-kappaB signalling in LPS-induced HK-2 cells. WEL improved renal injury by suppressing inflammation and cell apoptosis through upregulating PTPN2 in HK-2 cells. PTPN2 might be used as a potential therapeutic target for LPS-induced sepsis.

Autophagy flux contributes to regulation of components of Eclipta prostrata L. on cigarette smoking-induced injury of bronchial epithelial cells was written by Ding, Shumin;Hou, Xuefeng;Wang, Gang;Qiu, Huihui;Liu, Ying;Zhou, Yuanli;Du, Mei;Tan, Xiaobin;Song, Jie;Wei, Yingjie;Shu, Luan;Li, Zhiyong;Feng, Liang;Jia, Xiaobin. And the article was included in Frontiers in Pharmacology in 2018.Electric Literature of C16H10O7 The following contents are mentioned in the article:

Excessive autophagy plays a crucial role in cigarette smoking extract (CSE)-induced inflammation response and oxidative damage of respiratory epithelial cells. The components from Eclipta prostrata L. (CCE) have been shown to be beneficial for CSE-induced epithelial cells injury. However, whether its protection on CSE-stress injury is related to its regulation on autophagy remains still unclear. In this study, CCE, containing mainly wedelolactone of 45.88% and demethylwedelolactone of 23.74%, could improve significantly 10% CSE-induced cell viability of normal human bronchial epithelial (NHBE) cells using CCK-8 kit. We revealed that CCE could remarkably increase autophagic factors Beclin-1, Atg5, ATF4 proteins expression levels and the transformation of LC3-I to LC3-II. Addnl., CCE up-regulated significantly p-p16 and p-p21 phosphorylation levels whereas down-regulated p-p53 in NHBE cells. The changes of typical autolysosom and representative autophagosome in the presence of CCE or/and autophagy inhibitor chloroquine (CQ) were also observed by transmission electron microscopy. These data demonstrated that CCE reduced CSE-induced autophagy flux activation in NHBE cells. The blockade of CCE on autophagy flux contributes to its protection against CSE-induced NHBE cells damage, and CCE is promising to be combination therapeutic mols. to excessive autophagic damage in respiratory diseases.

Food & Function published new progress about 56317-21-6. 56317-21-6 belongs to benzofurans, auxiliary class Metabolic Enzyme,PDE,Natural product, name is 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol, and the molecular formula is C7H3Cl2F3O2S, Product Details of C14H10O4.

Zhou, Siqi published the artcileA chondroprotective effect of moracin on IL-1β-induced primary rat chondrocytes and an osteoarthritis rat model through Nrf2/HO-1 and NF-κB axes, Product Details of C14H10O4, the publication is Food & Function (2020), 11(9), 7935-7945, database is CAplus and MEDLINE.

Osteoarthritis (OA) is a common joint disease characterized by cartilage degeneration and inflammation. Although moracin is known to play a role in anti-inflammation and anti-oxidation in several inflammatory diseases, its anti-inflammatory effect on OA remains largely unknown. Therefore, in order to explore the role of moracin in OA, we investigated the anti-inflammatory effect of moracin on interleukin (IL)-β-induced rat chondrocytes in vitro and surgically induced OA rat models in vivo. Rat chondrocytes were pretreated using moracin (0, 5, 10, 15μmol L-1) and then stimulated with IL-β (10 ng ml-1). Results showed that moracin reduced the expression of IL-1β-induced nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX)-2 in both rat chondrocytes and cell culture supernatants. Besides, IL-1β-induced degradation of aggrecan and collage II, and the high expression of matrix metalloproteinase-13 (MMP-13) and a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS)-5 were also reversed by moracin. Moreover, moracin inhibited the translocation of p65 from the cytoplasm to nucleus induced by IL-1β and activated the Nrf2/HO-1 signaling pathway in chondrocytes. In OA rat models, moracin prevented cartilage of rats from destruction. All these findings above indicated that moracin could be a potentially effective drug for treating OA.

Six stilbene derivatives isolated from Mulberry leaves including Kuwanon X, Mulberrofuran C, Mulberrofuran G, Moracin C, Moracin M 3′-O-b-glucopyranoside and Moracin M were found to have antiviral effects against herpes simplex virus type 1 and 2 (HSV-1 and HSV-2) at different potencies except for Mulberrofuran G. Kuwanon X exhibited the greatest activity against HSV-1 15577 and clin. strains and HSV-2 strain 333 with IC50 values of 2.2, 1.5 and 2.5μg/mL, resp. Further study revealed that Kuwanon X did not inactivate cell-free HSV-1 particles, but inhibited cellular adsorption and penetration of HSV-1 viral particles. Following viral penetration, Kuwanon X reduced the expression of HSV-1 IE and L genes, and decreased the synthesis of HSV-1 DNA. Furthermore, it was demonstrated that Kuwanon X inhibited the HSV-1-induced nuclear factor (NF)-κB activation through blocking the nuclear translocation and DNA binding of NF-κB. These results suggest that Kuwanon X exerts anti-HSV activity through multiple modes and could be a potential candidate for the therapy of HSV infection.

Ben-David, O. published the artcileSimple Absorption Optical Fiber pH Sensor Based on Doped Sol-Gel Cladding Material, Category: benzofurans, the publication is Chemistry of Materials (1997), 9(11), 2255-2257, database is CAplus.

The construction and the operation properties of an organically doped sol-gel cladded optical fiber pH sensor, is described. The SiO2-entrapped indicator in the absorption-based device was α-naphtholphthalein, pumped with a continuous wave He-Ne 633 nm laser. The transmitted signal through the sensing fiber yields a response in the range pH = 4-11, where signal level doubled itself from base to acid. The dynamic range is high with a 100% change between these pH values, allowing pH determination in ∼0.2 pH units accuracy, better than the current status of analogous fluorescent based sensors. The high dynamic range apparently cannot be fully explained by simple evanescent field considerations. The design and setup are attractive because of the simplicity and very low cost. The probe is easily prepared under regular room conditions by simple decladding of the fiber and sol-gel recoating; the optical fiber probe is easily replaceable; the optical setup is trivial and involves inexpensive common parts, in particular the light source which can be a simple red diode laser.
