The RMSD profiles in Fig. 10A,B point out that cymaroside + amentoflavone maintains steady deviation values between 2.5 to three.2 Å, suggesting constant binding. In distinction, chlorpyrifos reveals larger RMSD fluctuations starting from 3.0 to 4.5 Å, indicative of a much less steady binding configuration throughout the enzyme’s energetic web site. Determine 10C demonstrates that residues throughout the binding web site interacting with cymaroside + amentoflavone exhibit RMSF values between 1.2 to 1.8 Å, reflecting decreased flexibility and a extra inflexible binding conformation. Conversely, chlorpyrifos-bound complexes show larger RMSF values (1.5 to 2.5 Å), indicating elevated residue mobility and probably destabilizing interactions. Interplay power evaluation in Fig. 10E reveals that cymaroside + amentoflavone varieties stronger Lennard–Jones and Coulombic interactions (−150 to −180 kJ/mol) in comparison with chlorpyrifos (−100 to −130 kJ/mol), suggesting a extra energetically beneficial and steady binding. Determine 10F reveals that cymaroside + amentoflavone constantly varieties 2 to 4 steady hydrogen bonds with distances of two.8 to three.2 Å, whereas chlorpyrifos varieties fewer and fewer constant hydrogen bonds with longer distances (3.2 to three.6 Å). Cymaroside + amentoflavone demonstrates enhanced binding stability, decreased flexibility, stronger interplay energies, and extra steady hydrogen bonding with COX1 in comparison with chlorpyrifos. These findings recommend that cymaroside + amentoflavone varieties a simpler and steady ligand–protein complicated.

Determine 11C,D illustrate that the RMSF values for receptor residues interacting with cymaroside + amentoflavone stay between 0.5–1.5 Å, indicating restricted flexibility and a extra inflexible binding conformation. Conversely, chlorpyrifos induces larger RMSF values exceeding 2 Å in sure areas, suggesting elevated native flexibility and probably much less steady binding interactions. Determine 11E reveals that cymaroside + amentoflavone varieties stronger Lennard–Jones and Coulomb interactions inside atomic distances (1–3 Å) in comparison with chlorpyrifos, which reveals weaker interplay profiles. Determine 11F highlights that cymaroside + amentoflavone constantly varieties extra frequent and steady hydrogen bonds inside an optimum distance vary (1.5–2.5 Å), whereas chlorpyrifos varieties fewer and extra transient hydrogen bonds with longer distances, indicating weaker interplay stability. Cymaroside + amentoflavone reveals superior binding stability, decreased receptor flexibility, stronger interplay energies, and extra steady hydrogen bonding with the ORs in comparison with chlorpyrifos. These outcomes recommend that cymaroside + amentoflavone is a simpler and steady ligand for focusing on the ORs.
Throughout all studied proteins: AGI, CEHs, CSPs, COX1, and the Ors, various ligand combos (chamazulene + robustoflavone, cynaroside + hinkoflavone, spathulenol + robustaflavone, and cymaroside + amentoflavone) constantly reveal superior binding stability, decreased flexibility, stronger interplay energies, and extra steady hydrogen bonding in comparison with the reference compound chlorpyrifos. These findings collectively spotlight the potential of those pure ligand combos as simpler and steady options to chlorpyrifos in modulating goal protein features. The improved binding traits of the choice ligand combos recommend their potential as viable substitutes or complementary brokers to chlorpyrifos, notably in purposes requiring steady and particular protein interactions.
