This study aimed to investigate the neuroprotective potential of sabinene in an Aluminum chloride (AlCl<sub>3</sub>)-induced model of AD in male Wistar rats. Thirty male Wistar rats were randomly divided into six groups (<i>n</i> = 6 per group). Group I (control) received normal saline for 30 days. Groups II–V were administered only AlCl<sub>3</sub> (100 mg/kg, orally) for 20 consecutive days to induce AD-like pathology, which was confirmed through behavioral assessments. Following induction, Group II (AD control) received 1% Tween 80; Group III (standard treatment) was administered rivastigmine (2.5 mg/kg); while Groups IV–VI received sabinene at doses of 5, 10, and 20 mg/kg, respectively, for 10 days 1 h prior to AlCl<sub>3</sub>. Behavioral evaluations were conducted on days 0, 20, and 31. On the 31st day, animals were sacrificed for biochemical and molecular analyses. In silico molecular docking studies revealed that sabinene exhibited a higher binding affinity towards AD-related targets (BACE1, GSK-3β, TACE, and AChE) compared to rivastigmine. In vivo, sabinene treatment significantly mitigated oxidative stress, restored antioxidant enzyme activities, reduced pro-inflammatory cytokine levels, AChE, BACE1, and GSK3β expression, and ameliorated histopathological alterations in the rat brain. Thus, sabinene exerts potent neuroprotective and disease-modifying effects in AlCl<sub>3</sub>-induced AD via AchE, BACE-1, and GSK3β Modulation.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":719,"journal":{"name":"Neurochemical Research","volume":"50 5","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test for the contribution of the purine salvage pathway to synthesize new adenosine monophosphate (AMP) for ATP restoration, several purine nucleosides and purine bases as well as their combinations were applied.

By such treatments, 80% of the initial ATP content were restored within 40 min. The supporting effects of inosine and guanosine on ATP restoration were prevented by the presence of forodesine, demonstrating the contribution of purine nucleoside phosphorylase in the ATP restoration observed.

This research aims to investigate the role and mechanisms of DIZE in CI/RI. C57BL/6J mice were treated with DIZE via intracerebroventricular injection for a week and middle cerebral artery occlusion/reperfusion (MCAO/R) models were established.

Primary cultures of astrocytes were prepared and exposed to oxygen-glucose deprivation/reoxygenation (OGD/R) to simulate in vitro ischemia/reperfusion. The IL-1β, IL-6 and TNF-α levels were detected by qRT-PCR and ELISA. Oxidative stress and lipid peroxidation indicators were measured using commercial assay kits. Western blot and immunofluorescence staining were used to measure the related protein levels. We found that DIZE alleviated neuronal injury and suppressed both neuroinflammation and astrocyte reactive changes in MCAO/R mice. In vitro, DIZE inhibited the release of inflammatory factors in primary cultures of astrocytes subjected to OGD/R. Furthermore, DIZE inhibited endoplasmic reticulum stress-mediated IRE1α-NF-κB pathway, increased NRF2 levels and suppressed oxidative stress, which was consistently observed in vivo and in vitro.

Ligand-based and proteochemometric models were used to predict potential protein targets, followed by molecular docking using PyRx and Discovery Video Visualiser. To validate these findings, DMF and TMF (10/20/40 mg/kg) were administered to LPS-induced mice for 21 days. Morris Water Maze (MWM) and Open Field Test (OFT) were conducted to assess cognitive functions.

Molecular docking showed DMF formed strong binding interactions with GABRA1 and GABRG2 (9.40 kcal/mol), interacting with His102 and Tyr160.

Sleep loss also induces low-grade neuroinflammation characterized by glial reactivity and blood–brain barrier (BBB) dysfunction, as evidenced by BBB hyperpermeability and tight junction disassembly. Additionally, it raises molecules related to the senescence-associated secretory phenotype (SASP) in aged subjects, suggesting an increase in senescent cells. Here, we assessed the impact of sleep restriction on cellular senescence, neuroinflammation, and BBB function in the cerebral cortex and hippocampus of young male C57BL/6 mice. Sleep restriction induced a progressive increase in BBB permeability after 3, 5, and 10 days, along with a higher expression of the astroglial marker, the glial fibrillary acidic protein (GFAP), and the expression of the C3 complement component. The pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6) increased in a region-dependent form. Furthermore, the progressive increase of the senescence markers β-galactosidase and p21 observed in both brain regions was accompanied by a neurotoxic astroglial response. Our data suggest that sleep restriction promotes cellular senescence in the cerebral cortex and hippocampus of young mice.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":719,"journal":{"name":"Neurochemical Research","volume":"50 5","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11064-025-04510-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
