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.

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.

1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds.

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. And the article was included in ACS Applied Materials & Interfaces in 2018.Formula: C16H10O7 The following contents are mentioned in the article:

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.

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.

Endocrine disrupters (EDs) form an interesting field of application attracting great attention in the recent years. They represent a number of exogenous substances interfering with the function of the endocrine system, including the interfering with developmental processes. In particular EDs are mentioned as substances requiring a more detailed control and specific authorization within REACH, the new European legislation on chems., together with other groups of chems. of particular concern. QSAR represents a challenging method to approach data gap which is foreseen by REACH. The aim of this study was to provide an insight into the use of QSAR models to address ED effects mediated through the estrogen receptor (ER). New predictive models were derived to assess estrogenicity for a very large and heterogeneous dataset of chem. compounds QSAR binary classifiers were developed based on different data mining techniques such as classification trees, decision forest, fuzzy logic, neural networks and support vector machines. The focus was given to multiple endpoints to better characterize the effects of EDs evaluating both binding (RBA) and transcriptional activity (RA). A possible combination of the models was also explored. A very good accuracy was reached for both RA and RBA models (higher than 80%).

The activity of 45 compounds against bloodstream forms of Trypanosoma cruzi was investigated. The aim was to consider new agents which might subsequently be assayed for chemoprophylaxis in donated blood. In a preliminary screening the drugs were assayed (50 to 1,000 μM at 29°C) and those active against bloodstream forms at concentrations below 600 μM were selected for further assays under blood-bank conditions (4°C/24 h). Three compounds isolated from natural sources and six synthetic agents were selected. The active compounds of plant origin included purpurin (I), a member of the trihydroxylated anthraquinone group, which is known to exhibit trypanocidal activity. Among the active synthetic compounds, five displayed a common structural feature in that they were potentially one-electron acceptors, via reductive functional groups. All five compounds form tricentered C or N intermediates, joined in a hypothetical Y radical pattern. It is possible that the trypanocidal mechanisms initiated by these compounds are similar to those found with crystal violet (II) , since this dye, which is already used in endemic areas for the treatment of banked blood, also conforms to this general Y structural pattern.
