The human YTHDF3 is a widely documented m6A reader that recognizes and interacts with m6A through its YTH domain, where the <i>N</i>⁶-methyl group of m6A is tightly captured by an aromatic cage defined by the YTH tryptophan residue triad Trp438–Trp492–Trp497. Considering that the aromatic cage has only a limited size that can accommodate only small atoms and moieties, we herein attempted to investigate the substitution effects of halogen modification of m6A's <i>N</i>⁶-methyl group (<span></span>N⁶H<span></span>CH₃) on YTHDF3 YTH recognition and binding. The <i>N</i>⁶-methyl group possesses three chemically equivalent hydrogens; each of which can be substituted by four halogens (X₁, X₂ and X₃ = F, Cl, Br and I). An integrated in silico-in vitro (<i>iSiV</i>) strategy was employed to examine the structural, energetic, and affinity effects of halogen modification on the binding of m6A mononucleotide to YTHDF3 YTH domain by systematically substituting one or more of the three <i>N</i>⁶-methyl hydrogens of m6A with four halogens, totally resulting in 34 <i>N</i>⁶-halomethyladenosine analogs (xm6A), including 4 single-, 10 double-, and 20 triple-substituted xm6A. It is revealed that the halogen modification can create favorable halogen–π interactions with the π-electron-rich aromatic cage, thus conferring affinity and specificity to the binding of xm6A to YTHDF3 YTH domain. However, multiple substitutions with bulky halogen atoms such as I would cause unfavorable steric overlaps and clashes against the small aromatic cage, thus considerably impairing the binding potency of the resulting xm6A. The native m6A mononucleotide binds to YTH with a moderate affinity, which can be modestly or considerably improved by different single-halogen substitutions. The single Br-substitution and double Cl-Br-substitution were determined as the best candidates to improve xm6A binding affinity, which are good compromises between the favorable halogen–π interactions and unfavorable steric effects eliciting from the substitutions.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 9","pages":"974-984"},"PeriodicalIF":1.5,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is urgently required to develop a method of detection with rapid response time and low detection limits. HPQRB has great fluorescent properties; it has a low detection limit and rapid response time. In this article, the detection mechanism of fluorescent probe HPQRB for HSO₃⁻ and the excited-state intramolecular proton transfer (ESIPT) process have been unveiled by density functional theory (DFT) and time-dependent density functional theory (TD-DFT). HPQRB and HPQRB-HSO₃ both have planar structures in the ground state (S₀) and the first excited (S₁) state. Combining structural parameters and infrared vibrations, the hydrogen bond has been strengthened upon photoexcitation, providing the driving force for the ESIPT process. Orbital-weighted Fukui function and dual descriptor confirm that C₉ (shown in Figure 1) of HPQRB is the reaction site of HSO₃⁻ attacking. The calculated absorption and emission are consistent with the experiment, indicating that our calculations are reliable. By building potential energy curves (PECs), we find that the high reaction barrier from keto form to enol form in the S₁ state is the reason why HPQRB-HSO₃ only has one emission peak. Natural transition orbitals (NTOs) and hole–electron show that both HPQRB and HPQRB-HSO₃ are local excitation (LE) and exhibit ππ* properties. Compared with HPQRB, the conjugated structure of HPQRB-HSO₃ after Michael addition is disrupted, causing a weaker electron transfer after photoexcitation, which leads to the blue shift of the emission peaks.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 9","pages":"993-1001"},"PeriodicalIF":1.5,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to water and conventional organic solvents, the relatively high viscosity of ionic liquids offers a distinct advantage in controlling the modification process, as the reduced mass transfer leads to a slower and more manageable displacement rate. This control is crucial; excessive deposition of Pd or Pt on the Cu surface can result in diminished, rather than enhanced, electrochemical nitrate reduction activity. Cu surfaces modified with an appropriate amount of Pd or Pt exhibited improved electrochemical performance toward both nitrate (NO₃⁻) and nitrite (NO₂⁻) reduction. This enhancement is likely attributed to the increased porosity induced during the galvanic displacement process, as well as synergistic effects between Pd/Pt and Cu. Overall, galvanic displacement in ionic liquids represents a practical and effective strategy for the synthesis of Cu-based electrocatalysts for electrochemical nitrate reduction.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 9","pages":"1011-1018"},"PeriodicalIF":1.5,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jccs.70072","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
