The nociception (NOP) receptor is structurally similar to the opioid receptor, but NOP is known to have a low affinity for the opioid receptor subtypes μ, δ, and κ. In previous studies, we synthesized peptides with a high affinity for opioid receptors and investigated their antidepressant-like effects in mice. However, we have not yet examined whether NOP-related analogs have antidepressant-like effects. Herein, we synthesized NOP analogs (peptide-1-peptide-8) by solid-phase peptide synthesis using the 9-fluorenylmethyloxycarbony (Fmoc) method with Acetyl-Arg-Tyr-Tyr-Arg-Ile-Arg-NH₂ (Ac-RYYRIR-NH₂) as the lead compound. We examined the affinities and antagonistic activities of the analogs for the NOP receptor using receptor-binding and mouse vas deferens assays, and their effects on the duration of immobile behavior in a tail suspension test. Peptide-6 showed a high affinity and antagonistic activity for the NOP receptor. The intracerebroventricular administration of peptide-6 in mice shortened the duration of immobile behavior, whereas the co-administration of NOP inhibited this effect. Moreover, intracerebroventricular administration of the selective NOP receptor antagonist J-113397 showed antidepressant-like effects in mice. These data suggest that peptide-6 exerts an antidepressant-like effect via inactivation of the central NOP receptor in mice and may represent a lead compound for the development of antidepressant drugs in the future.</p>","PeriodicalId":8955,"journal":{"name":"Biological & pharmaceutical bulletin","volume":"48 5","pages":"682-686"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141151","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}

However, because herbal medicines contain many components, their pharmacological effects have not been analyzed in detail. Risperidone and quetiapine are prescribed in severe cases; however, their side effects of oversedation are problematic. Tokishigyakukagoshuyushokyoto (TSGST) is a herbal medicine prescribed to improve blood circulation and relieve headaches, back pain, or chilblains associated with hemodynamic insufficiency. Interestingly, most of the individual components of TSGST are known to exert sedative or analgesic effects. In this study, we investigated whether TSGST ameliorates aggressive behavior induced by social isolation in mice. The mice were isolated for 5 or 6 weeks immediately after weaning and given TSGST via a water bottle during this period. Long-term administration of TSGST suppressed the onset of aggression induced by isolation rearing.

Despite these established effects, its potential in mitigating hepatic injury remains to be fully explored. The present investigation delineates the hepatoprotective efficacy of FR429 and unveils its underlying molecular mechanisms. Initially, of the tested compounds, 10 compounds (specifically, compounds 2, 4, 5, 6, 7, 8, 9, 12, 13, and 14) exhibited significant protective effects at a concentration of 10 μM, elevating HepG2 (human liver cancer cell) cell viability from 43.4 to 70% following carbon tetrachloride (CCl₄) exposure. Among them, compounds 2 (FR429, half-maximum effective concentration (EC₅₀) = 6.46 μM) and 6 (2\"-O-galloylquercitrin, EC₅₀ = 5.36 μM) demonstrated the highest cytoprotective activities. In the murine model, FR429 dramatically attenuated serum levels of alanine transaminase, aspartate transaminase, and alkaline phosphatase, indicative of its hepatoprotective potential. Histopathological evaluation further substantiated these findings, as FR429 noticeably mitigated CCl₄-induced hepatic lesions, involving necrosis, ballooning degeneration, and neutrophil infiltration. Transcriptomic analysis unveiled 178 differentially expressed genes in FR429-treated mice liver tissue, with significant alterations indicative of a hepatoprotective response. Mechanistic investigations revealed that FR429's hepatoprotective effects involve modulation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, evidenced by downregulation of toll-like receptor 2, phosphorylated PI3K, phosphorylated Akt, nuclear factor-kappa-B, interleukin-1 beta, and tumor necrosis factor-alpha expression. Furthermore, FR429 modulated the gene and protein expression levels of apoptotic markers (apoptotic protein (Bax) and B-lymphoblastoma-2 gene (Bcl2)), reinforcing its anti-hepatic damage efficacy. This study represents the first report establishing FR429 as an effective hepatoprotective compound, paving the way for further investigation into its therapeutic applications.</p>","PeriodicalId":8955,"journal":{"name":"Biological & pharmaceutical bulletin","volume":"48 4","pages":"372-382"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956800","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}

The aim of this study was to investigate the effects of APS on cognitive function in d-galactose (d-gal)-induced aging rats and explore the potential underlying molecular mechanisms. The rats were induced to age by intraperitoneal injection with 400 mg/kg/d d-gal for 8 weeks. Aging of rats was assessed through the Morris water maze test, step-down test, open field test, and grip strength test. Pathological changes in the hippocampal CA3 and CA1 regions were determined by Hematoxylin and eosin and Nissl staining. The superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), and total antioxidant capacity (T-AOC) in the serum were measured. Telomere length, dual oxidase 1 (Duox1), dual oxidase 2 (Duox2), peroxiredoxin 1 (Prdx1), p21, p16, p53, telomerase reverse transcriptase (TERT), phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), nicotinamide phosphoribosyl transferase (NAMPT), and sirtuin 1 (SIRT1) were detected via real-time PCR, Western blotting, and immunohistochemical staining. The results indicated that APS ameliorated the general status in d-gal-induced aging rats, mitigated neuronal degeneration in the CA3 and CA1 regions, reduced the oxidative stress levels, modulated senescence-related β-GAL and protein expression, and maintained telomere length. Furthermore, APS significantly reduced p53 expression and increased p-PI3K, p-AKT, NAMPT, SIRT1, and TERT expression. Therefore, d-gal-induced aging and cognitive impairment in rats can be prevented by APS, likely through regulation of the TERT/p53 signaling axis via the PI3K/Akt and NAMPT/SIRT1 signaling pathways.</p>","PeriodicalId":8955,"journal":{"name":"Biological & pharmaceutical bulletin","volume":"48 5","pages":"523-536"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143964600","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}

In a previous study, we synthesized 6-hydroxy-3'-propyl-[1,1'-biphenyl]-3-propanoic acid (6OHA) based on the structure of magnaldehyde B, a natural compound that our group identified as a retinoid X receptor (RXR) agonist. However, its potential effects on inflammation in microglial cells remain unexplored. In this study, we specifically focused on the early-phase inflammatory responses to lipopolysaccharide (LPS) and evaluated the inhibitory effects of 6OHA on BV-2 microglial cells following 2 h of LPS exposure. Similar to the existing RXR agonist bexarotene (Bex), 6OHA treatment (0.1 and 1 μM) resulted in a dose-dependent decrease in the mRNA levels of proinflammatory mediators, including interleukin-1β (Il1b), Il6, and inducible nitric oxide synthase. However, these effects on proinflammatory mediators were effectively abolished by the RXR antagonist UVI3003. Additionally, 6OHA promoted M2 microglia polarization after 24 h of treatment, as evidenced by the increased mRNA levels of the M2 marker genes arginase-1 (Arg1), C-C motif chemokine ligand 6 (Ccl6), Ccl17, and Ccl22. Notably, 6OHA induced a distinct set of M2 microglial markers compared with IL-4, a known M2 microglial inducer. Furthermore, the transcription of Arg1, a key M2 marker gene, is regulated by retinoic acid receptor/RXR heterodimers and the IL-4 signaling pathway. Collectively, 6OHA suppressed the early inflammatory responses to LPS and promoted M2 microglial polarization through a mechanism distinct from that of IL-4. Therefore, RXR agonists, including 6OHA and Bex, may exhibit dual anti-inflammatory effects and serve as novel modulators of neuroinflammation.</p>","PeriodicalId":8955,"journal":{"name":"Biological & pharmaceutical bulletin","volume":"48 4","pages":"440-449"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143965820","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, involving 152 adult patients with asthma, aimed to assess the influence of VDR and GC polymorphisms on asthma severity and its exacerbation. Gene polymorphisms previously associated with asthma risk were analyzed, and VDR mRNA expression levels were evaluated in peripheral blood mononuclear cells. The AA genotype of the VDR rs2228570 polymorphism was associated with an elevated risk of severe asthma compared to the AG/GG genotype (odds ratio, 3.20; 95% confidence interval [CI], 1.24-8.28).
