In this study, the [14]pyridine@[8]MCPP system formed by assembling [8]cycloparaphenylene ([8]MCPP) with [14]pyridine methylene-bridged nanobelts was investigated using density functional theory (DFT) calculations as a potential sensor for five amino acids: glycine (Gly), alanine (Ala), threonine (Thr), leucine (Leu), and aspartic acid (Asp). The sensing capabilities of the assembled structure were evaluated through various analyses, including frontier molecular orbital (FMO), density of states (DOS), quantum theory of atoms in molecules (QTAIM), non-covalent interactions (NCI), and electron density difference (EDD). The energy gap of the [14]pyridine@[8]MCPP assembly was influenced by the presence of amino acids, with the most significant change (−8.75 %) observed in the [14]pyridine@[8]MCPP/Asp complex. Furthermore, QTAIM and NCI analyses indicated that the interactions between AAs and the [14]pyridine@[8]MCPP assembly are primarily governed by van der Waals (vdW) forces. The short recovery times (3.47 × 10<sup>−10</sup> to 1.27 × 10<sup>−6</sup> s) and favorable sensor responses (0.09–0.17) of the [14]pyridine@[8]MCPP/AA complexes at 298 K suggest that this assembly could serve as an effective material for detecting amino acids. These findings underscore the potential of assembled nanostructures as valuable candidates for amino acid sensing applications.</div></div>","PeriodicalId":16361,"journal":{"name":"Journal of molecular graphics & modelling","volume":"138 ","pages":"Article 109056"},"PeriodicalIF":2.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lengthy process of drug discovery further makes this task exceedingly challenging. To enable a rapid stride in drug discovery, we focused on the drug repurposing strategy to identify new N-methyl-D-aspartate receptor (NMDAR) inhibitors from the pool of 1827 approved USFDA drugs. The high throughput virtual screening (HTVS) followed by molecular docking and molecular mechanics studies enabled us to identify two drugs, Ertugliflozin (Dock Score: −9.43 kcal/mol, MMGBSA: −104.50 kcal/mol) and Selpercatinib (Dock Score: 8.11 kcal/mol, MMGBSA: 83.62 kcal/mol), with a high affinity towards the NMDAR. The molecular dynamics analysis on these identified drugs led us to choose Ertugliflozin for its better stability as a lead for further studies. The corroboration of in silico findings led us to deduce that Ertugliflozin can inhibit NMDAR with an IC<sub>50</sub> of 613.19 nM. These results were confirmed by the anti-NMDAR ELISA-based analysis, which was further deduced via western blotting. The work is further supported by strong literature evidence that concludes the impact of antidiabetic molecules on AD progression, along with the evidence that Ertugliflozin possesses efficacy against AD with unequivocal evidence on the biological target and the mechanism. Further work, however, is required to establish this association in the in vivo or suitable model that could mimic the AD microenvironment as a part of future research.</div></div>","PeriodicalId":16361,"journal":{"name":"Journal of molecular graphics & modelling","volume":"138 ","pages":"Article 109036"},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
