In this study, we report that the diastereoselective course of the Norrish-Yang reaction of imidazolidinone derivatives is reversed by the addition of tetrabutylammonium salts (TBAX). 1H NMR experiments suggested that cation-π interactions between TBA+ and the substrate control the reactive conformation of this latter species. In the course of this study, we found that unexpected compounds with 6/7/5- and 6/6/5-fused tricyclic systems containing an aromatic ring were also formed in the presence and absence of TBAX, respectively. Furthermore, we report the formation of an unexpected fused tetracyclic compound, the framework structure of which resembles that of a tetraquinane, when a substrate with 2-benzoylethyl side chains on both nitrogen atoms of the imidazolidinones is used.","PeriodicalId":57,"journal":{"name":"Journal of Organic Chemistry","volume":"77 1","pages":""},"PeriodicalIF":4.354,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, by developing a data-driven bottom-up coarse-grained model using discrete molecular dynamics simulations, we found proteins in the condensates of TDP-43 forming a dynamic network of fluctuating sizes. While dominated by peptides engaged with a small number of peptides connected by a low number of interpeptide contacts, the condensates also contained peptides with large numbers of connections, serving as hubs of a small-world network. Importantly, peptides in these high-contact states were intertwined to form oligomers that were stable for relatively long periods inside the weakly connected network. These oligomers were likely the aggregation intermediates toward nucleation of amyloid fibrils. Therefore, this transferable coarse-grained model may serve as a powerful tool for unraveling the inner workings of LLPS and amyloid aggregation.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"9 1","pages":"7797-7806"},"PeriodicalIF":6.475,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated these associations and examined the mediating role of maternal and neonatal thyroid hormones in a Chinese birth cohort consisting of 501 mother-child pairs. We found that exposure to 2-hydroxy-benzothiazole (2-OH-BTH) in early pregnancy was inversely associated with childhood body mass index (BMI) (β = -0.041, 95% CI: -0.077, -0.005). Both tolyl-triazole (TTR) (β = -1.35%, 95% CI: -2.45%, -0.24%) and 2-OH-BTH (β = -1.15%, 95% CI: -1.79%, -0.50%) were inversely associated with maternal free thyroxine (FT4) in early pregnancy, which mediated 23.53% of the inverse associations between 2-OH-BTH exposure and childhood BMI. Additionally, third-trimester exposure to 1-hydroxy-benzotriazole, xylyl-triazole, TTR, and 2-OH-BTH was positively linked to neonatal thyroid-stimulating hormone levels. These findings suggest that prenatal exposure to BTs, particularly 2-OH-BTH, may impair early childhood growth by disrupting thyroid hormone homeostasis. Our results add new epidemiological evidence to the growing concern about BTs and underscore the importance of considering thyroid disruption as a mechanistic link between environmental exposures and developmental outcomes. This highlights the need for greater public health attention and regulatory measures targeting these emerging contaminants.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"16 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
