Abstract
Cenobamate, which is a voltage-gated sodium channel (VGSC) blocker, finds its full application in several anti-epileptic medications. This manuscript tries to look at the structure and other physicochemical properties of this compound with electronic structure methods and molecular mechanics tools. Density functional theory was used to optimise the ground-state geometry of the molecule using dispersion-corrected omega-B97XD functional using aug-cc-pVDZ basis sets, from which frontier molecular orbitals were studied. This study gave a myriad of information about the electronic properties and descriptors that are well enough to predict the bioactivity of the molecule. Electronic excitations between different energy levels, resulting from the interaction between the electrons and electromagnetic radiation, were analysed using time-dependent density functional theory with CAM-B3LYP functional. Numerous parameters like Fukui, ALIE and MESP provided an ample amount of information about the reactivity preferences of the molecule. Molecular docking studies predicted the biological activity of the molecule and its possible use as an anti-depressant. As it was found to show biological activity, its liquid-state behaviour in different solvents was mapped using molecular dynamics simulations.
