This process gives rise to potential environmental concerns that must be addressed. In recent years, there has been significant interest in the role of TCEP in the development of hyperuricemia (HUA). However, the specific mechanisms by which TCEP contributes to this condition remain to be fully elucidated. In this study, we have employed a combination of network toxicology and in vitro experiments to investigate the potential effects of TCEP on HUA and its mechanism of action. Through systematic analysis of GeneCards, OMIM, Swiss Target Prediction, and CHEMBL databases, a total of 242 TCEP-induced HUA targets were identified. Utilizing the STRING and DAVID databases further elucidated the core targets and associated signaling pathways of TCEP in relation to HUA. The molecular docking assay results demonstrated that TCEP exhibits binding activity with the selected targets. In vitro, our findings revealed that TCEP exacerbates HUA by amplifying the inflammatory response and upregulating the mRNA expression levels of GLUT9 and URAT1. The present study provides a new perspective and theoretical basis for the in-depth understanding of the molecular mechanism of TCEP affecting HUA, and helps to further understand the pathogenesis of HUA and the role of environmental factors.","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144607827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mice with CCl4-mediated liver fibrosis were administered TA treatment for 6 weeks. Histopathological alterations in liver tissues were evaluated, and serum markers of hepatic injury, as well as the hepatic profibrotic gene and protein levels were detected. Transforming growth factor-β1 (TGF-β1) was adopted for inducing LX-2 cells. Following a 24-h TA intervention, we assessed pro-fibrotic gene and protein activation, proliferation and levels of TGF-β1-activated LX-2 cells. miR-155 and FOXO3 expressions were quantified in mice liver tissues and cells. The targeting relation of miR-155 with FOXO3 was verified. After regulating miR-155 and FOXO3 expression, the function of TA in cell activation, proliferation, and collagen accumulation was evaluated. The results indicated that TA treatment markedly alleviated CCl4-mediated mouse liver injury, inhibited collagen fiber deposition, and downregulated the hepatic pro-fibrotic gene and protein levels. Additionally, TA treatment suppressed TGF-β1-induced cell activation and proliferation, thus significantly reducing pro-fibrotic marker levels within cells. Furthermore, treatment with TA down-regulated miR-155 and up-regulated FOXO3 within CCl4-induced liver tissues as well as TGF-β1-induced cells. However, miR-155 overexpression or FOXO3 silencing partially mitigated the inhibition of TA against TGF-β1-mediated activation, proliferation, and fibrosis in cells. In conclusion, TA inhibits the activation of hepatic stellate cell (HSC) via miR-155/FOXO3 axis, thereby exerting its anti-hepatic fibrosis effect.","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1-13"},"PeriodicalIF":2.1,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144599699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study leverages integrated in silico approaches, encompassing ensemble docking, molecular dynamics (MD) simulations, dynamic unbinding (DUck), and ADMET predictions, to identify novel saquinavir-related antiviral inhibitors targeting the catalytic dyad and oxyanion-hole loop of the SARS-CoV-2 main protease (Mpro). From a library of 33 saquinavir-related analogs, ensemble docking identified three high-affinity ligands (ΔG ≤ -9.8 kcal/mol). Subsequent MD simulations revealed stable Mpro-ligand complexes and significant structural perturbations within the catalytic dyad (His41-Cys145, ΔDdyad >1.0 Å) and the oxyanion-hole (Gly143-Ser144-Cys145, Δθoxy >5°). DUck simulations elucidated a stepwise dissociation mechanism, identifying key hotspot residues critical for ligand binding. Compounds CHEMBL3706523 and CHEMBL3706524 emerged as promising candidates, exhibiting robust interactions and slower dissociation rates (WQB >6 kcal/mol). These ligands stabilized the receptor and induced conformational changes that may hinder substrate binding, suggesting a potential 'block cluster' mechanism for inhibition.

In both acute and repeated subacute toxicity test, no AAL-related behavioral abnormalities or changes in mortality, food intake, body weight were observed up to a dosage of 2000 mg/kg, indicating that the median lethal dose of AAL is higher than 2000 mg/kg. In subacute toxicity tests, no significant changes in hematological and biochemical parameters, urinalysis results, and histopathological variables were observed. Therefore, the no-observed-adverse-effect level (NOAEL) of orally administered AAL was estimated to be 2000 mg/kg/day in male and female rats. We also examined the effect of AAL on the inflammatory reaction in lipopolysaccharide (LPS)-stimulated BV-2 cells. AAL treatment significantly inhibited the LPS-stimulated increases in the levels of nitric oxide (NO) and inflammatory cytokines, implying that AAL has an anti-inflammatory effect. Quality control analysis revealed that two marker compounds, rutin and isoquercitrin, were present at 27.570 and 4.322 mg/g, respectively, in a freeze-dried AAL sample and were completely eluted within 27 min.

This study is mainly aimed to assess the cardiotoxicity of xanthatin in vivo using zebrafish larva and in vitro using cardiomyocytes H9C2. The cardiotoxicity in zebrafish was assessed by the pericardial edema, blood flow dynamics, SV-BA distance, and sub-intestinal vein. The apoptosis was determined by AO staining, the blood red cell reduction and distribution was detected by O-dianisidine staining, histopathological evaluations were detected by HE staining. The anti-proliferative and pro-apoptotic activities in H9C2 cells were assessed by EdU staining and Hoechst 33342/PI double staining. The in vivo results showed that xanthatin caused cardiac malformations and dysfunctions, including decreased heart rate, reduced red blood cell count, hemodynamics, stroke volume, increased SV-BA distance and sub-intestinal vein congestion. Furthermore, apoptosis occurred in the heart of the zebrafish after xanthatin exposure. Additionally, cat, Mn-sod, chop, perk, and hspa5 related to oxidative stress and ERS also changed by xanthatin. Apoptotic genes caspase3 and caspase9 were also increased. Moreover, the in vitro results showed that xanthatin had proapoptotic and antiproliferative effects.

Knowing the pharmacokinetic and pharmacodynamic (PK/PD) parameters of L-Asp as well as its relationship with the development of AE is an important strategy in the search to improve the efficacy and safety of the treatment. Seventy-four children with ALL that were being treated with L-Asp, were included. One to three blood samples were randomly obtained from each patient, at times from 0 to 30 hours, until completing a total of 211 samples. The L-Asp activity and the Asparagine (Asp) concentration were quantified, in addition, the presence of anti-L-Asp antibodies (Anb) was determined. A population PK/PD model of L-Asp was developed to determine the association of covariates with PK/PD parameters. The presence of Anb was associated with the increase in L-Asp clearance (CL) and with the decrease of volume of distribution 1 (V1). On the other hand, female sex was significantly associated with the increase of V1, while the age from 1 to 6 years was significantly associated with the increase of V1. The presence of Anb as well as the female sex were related to the increase IC50 (concentration-needed to deplete-50% of Asp). Patients who presented Asp depletion before the first 24 hours after administration presented pancreatitis, this could be a risk marker. Significant results were found in this study, use of these results may contribute to the safe and effective use of L-Asp.","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"743-757"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142460504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
