HOMO orbitals were found to localize strongly on the ligands, reducing conductance by ∼67–76 % relative to 102d. Classical molecular dynamics and MM/GBSA binding‐energy analyses were used to explore potential relationships between ligand binding strength, orbital localization, and transport suppression. Within the statistical uncertainty of the free‐energy estimates, the calculations support a qualitative trend in which configurations with stronger enthalpic stabilization tend to exhibit enhanced HOMO localization and reduced conductance. However, the absence of a simple one-to-one correlation indicates that electronic transport is governed more by the specific binding mode and the resulting orbital redistribution than by the magnitude of binding affinity alone. These results therefore suggest a complex interplay between binding thermodynamics and quantum conductance, highlighting the dual role of ligand intercalation in stabilizing DNA while modulating its electronic delocalization.</div></div>","PeriodicalId":16361,"journal":{"name":"Journal of molecular graphics & modelling","volume":"143 ","pages":"Article 109263"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145827801","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}

Density Functional Theory (DFT) and Generalized Gradient Approximation (GGA-1/2) were used for this purpose. The Perdew-Burke-Ernzerhof (PBE) method was used to calculate the exchange-correlation energy. Results demonstrated that hydrogenation of AΨGNRBs causes a band gap of about 0.73 eV with slight changes due to the varied length of the nanoribbon (NRB), but with a constant value of 0.7366 in repetitions from 4 to 10. They are utilized in the fields of optoelectronics, photonics, LEDs, lasers, sensors, and photonic devices. This NRB is a non-magnetic N-type semiconductor. It is used in transistors, and quantum devices that require precise electronic (rather than spintronic) control. However, ZΨGNRBs with changing the length and a repetition number from 1 to 10 are non-magnetic conductors, and edge hydrogenation does not cause a band gap. These nanostructures are compatible with conventional electronic (non-spintronic) devices. The formation energy of hydrogen-passivated AΨGNRBs and ZΨGNRBs is lower than that of the non-passivated counterparts, indicating greater stability of the passivated NRBs. Moreover, the formation energy of AΨGNRBs from 1 to 10 repetitions is lower than that of ZΨGNRBs. This significant reduction in the formation energy indicates greater stability and a more optimal structure of AΨGNRBs compared to ZΨGNRBs.

The study employed molecular docking investigation to screen 222 derivatives against ERK2. The findings shortlisted 10 compounds based on the binding affinity score. 3/10 were further selected as the top 3 hits. The top 3 hits are Dicumarol (−9.7 kcal/mol), 2, 3, 9, 10-Tetrahydroxyberbine (−8.8 kcal/mol), and Nafenopin (−8.3 kcal/mol). The AZD0364 (−9.8 kcal/mol) was used as a reference/control in the present study. The compounds were further assessed for pharmacokinetics feature prediction; hence, all the compounds met the Lipinski Rule 5 parameters with no violations observed. The molecular dynamics (MD) simulation trajectory for the ERK2-ligand complexes yielded satisfactory results, characterized by a strong interaction and intermolecular conformational stability. The mean root mean square deviation (RMSD) noted for the top 3 complexes was <2 Å. The post-MD simulation analysis was performed to enhance and validate the efficacy of the complexes.

Although protonation in acidic environments alters the effectiveness of both chemicals, DFT simulations show that they both efficiently decrease corrosion.

The strong interactions between metals and inhibitors have been explained by finding reactive areas on oxygen, nitrogen, and sulfur atoms by molecular electrostatic potential studies and Fukui indices.
