Abstract
Bacteria have developed a tolerance due to the overuse of antibiotics. Even though thyme essential oils have antibacterial properties, their utilization is restricted because of their instability. To overcome these limitations, one strategy is to interact the oils with other molecules. This research delved into the effective role of B12N12 in attaching thymol and carvacrol oils as a nanocarrier in drug delivery using density functional calculations (DFT) in both gas and solvent phases. Thymol and carvacrol oils have been found to interact with B12N12 through oxygen atoms, resulting in adsorption energies (Ead) of –12.49 and –12.39 kcal/mol on the nanocage, respectively. The adsorption and solvation energy values, along with notable alterations in the polarity of the complexes, indicated the potential of the B12N12 nanocage as an effective delivery carrier for the oils. The analysis of the quantum theory of atoms in molecules (QTAIM), the electron localization function (ELF), localized orbital locator (LOL), and density of states (DOS) showed that the nature of the interaction between the oils and the nanocage is non-covalent, which is beneficial for the release of the oils in drug delivery. The quantum molecular descriptors (QMDs) and the vibrational frequency calculations indicated that the complexes are stable. Moreover, Mulliken population analysis (MPA), molecular electrostatic potential (MEP), UV-Vis spectra, and thermodynamic parameters for the molecules were calculated. In silico molecular docking, 4WUB and 3VSL receptors were used to investigate thymol, carvacrol, thymol/B12N12, and carvacrol/B12N12 compounds inhibitor properties. The molecular docking analysis showed that the thymol/B12N12 and carvacrol/B12N12 compounds have the free negative binding energy values and low Ki (inhibition constant) values. This suggests that these compounds are more suitable for interacting with the 4WUB and 3VSL receptor targets compared to the Thymol and Carvacrol oils.
