The rapid and economical determination of ACM in food products poses a major challenge for food safety. This research intended to fabricate a simple, selective, and cost-effective polymeric-coated graphite sensor. This potentiometric sensor is suitable for direct and in situ ACM analysis in food products without tedious sample pretreatment procedures. The sensor was successfully developed based on the ion association complex of the ACM cation with sodium tetraphenylborate (TPB) anion as an ion exchange site, using dibutyl phthalate (DBP) as a plasticizer. The sensor demonstrated a fast, stable, selective, and linear Nernstian response (57.45 mV/decade) over a wide concentration range from 1 × 10<sup>−7</sup> to 1 × 10<sup>−1</sup> M of ACM, with a detection limit of 1 × 10<sup>−8</sup> M. The sensor’s selectivity behavior, response time, lifetime, pH working range, and fundamental validation parameters were assessed. Compared to a published chromatographic method, the developed sensor operated effectively to determine the ACM content in several food products. Greenness and whiteness were also assessed for the developed sensor, confirming that it is an excellent green and cost-effective option. Furthermore, the developed sensor was compared statistically with recently published ACM sensors to ensure optimal performance.</p></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01501-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This protein is essential for the regulation of cell growth, differentiation, programed cell death, and survival. This regulation is achieved through the release of intramolecular autoinhibition and the modulation of several signaling pathways, including the signaling cascade of Ras-MAPK. Mutations in SHP2 are frequently associated with human malignancies and neurodevelopmental disorders (NDDs). Specifically, a germline mutation (E76D) in SHP2 is linked to neurodevelopmental disorders, such as Noonan syndrome, while somatic mutations (E76G and E76A) and altered SHP2 expression are implicated in several forms of leukemia. These mutations disrupt the closed conformation, which normally keeps SHP2 in an inactive, auto-inhibited state, thereby enhancing phosphatase activity and activating SHP2, leading to a gain-of-function effect. However, the structural and functional implications of these disease-related mutants are not well elucidated. Therefore, in this study, we investigate the structural mechanisms underlying three distinct gain-of-function SHP2 mutations (E76D, E76G, and E76A) through the application of molecular dynamics (MD) simulations, focusing on how a single amino acid mutation at the same position result in different disease phenotypes, either cause cancer or NDDs. Notably, Patients with Noonan Syndrome have an increased risk of developing cancer, suggesting a potential link between these diseases and their mutations. MD simulation was employed to elucidate this mechanism, examining four distinct states: Apo-state (E76), M1-state (E76D), M2-state (E76G), and M3-state (E76A). The dynamics and conformational changes of SHP2 in both its Apo-state and mutant states (M1, M2, and M3) were compared. Our findings indicate that both cancer-related and NDD-related mutations destabilize the N-SH2 and PTP interface, facilitating SHP2 activation. However, the cancer-associated mutations induce more severe disruption at the N-SH2 and PTP interface than the NDD mutations. Additionally, dynamic analyses revealed that mutations at the interface (M1, M2, and M3) not only alter the native folded conformation of SHP2 but also significantly enhance the C-distance between the N-SH2 and PTP domains. Overall, this study provides a comprehensive understanding of the structural dynamics of SHP2 at the atomic level, revealing how mutations disrupt its auto-inhibition and increase PTP activity, providing valuable insights into the molecular mechanisms driving both cancer and neurodevelopmental disorders.</p></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01494-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antibacterial testing revealed that 2-(2,4-dichlorophenyl)benzo[<i>d</i>]imidazo[2,1-<i>b</i>]thiazole-7-sulfonamide displayed significant activity against Gram-positive bacteria, with MICs as low as 6.25 µg/mL for <i>Staphylococcus aureus</i> and <i>Bacillus subtilis</i>. The molecular docking and DFT analyses provided insights into the binding interactions and electronic structures of these compounds, with halogen substitutions enhancing biological activity due to increased electron-withdrawing effects. MESP studies showed a distinct electron density distribution, supporting the observed bioactivity. For antitubercular activity, compounds <b>5b</b>, <b>5d</b>, and <b>5h</b> demonstrated potent binding affinities (−6.2 to −5.9 kcal/mol) against the DprE1 enzyme. Compound <b>5f</b> showed remarkable antibacterial efficacy, with a docking score of −7.9 kcal/mol against 2,2-dialkylglycine decarboxylase The DFT analysis revealed that <b>5a</b>, with a methoxy substituent, had the highest reactivity (ΔE = 3.86 eV), while halogenated derivatives, such as <b>5f</b>, exhibited increased chemical stability (ΔE = 4.24 eV). ADME studies showed that <b>5f</b> having favorable lipophilicity and enzyme inhibition. These findings suggested that these derivatives could serve as potential candidates for further drug development against bacterial and mycobacterial infections.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01405-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most potent derivative with IC<sub>50</sub> values of 12.84 ± 0.84 and 10.90 ± 0.84 µM against MCF-7 and SW480 cell lines was comparable to Cisplatin and Erlotinib as positive controls. Cell cycle analysis showed that the most active compound could arrest at S phase in MCF-7 breast cancer cells. The apoptosis assay demonstrated the induction of apoptosis in the MCF-7 cell line, too. Molecular docking results showed better accommodation of the most active compound through hydrogen bonding interaction in the binding site of EGFR enzyme. Molecular dynamics simulations for the potent analogue demonstrated well binding stability compared to the less active analogue, with a lower RMSD, Rg and more interactions with the original active site residues. DFT calculations were performed on the active and inactive compounds, using Gaussian 09 at the M06-2X/6–31 + G(d) theoretical level. ADME (Absorption, Distribution, Metabolism, and Excretion) properties showed that most of the compounds are in acceptable range of Lipiniski rule. These findings underscore the potential of the synthesized compounds as potent cytotoxic inhibitors and provide insights for developing effective treatments for cancer therapy.</p></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01492-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
