Metal oxide nanocage as drug delivery systems for Favipiravir, as an effective drug for the treatment of COVID-19: a computational study

This paper is a summary of research that looks at the potential of fullerene-like (MO)(12) nanoclusters (NCs) in drug-carrying systems using density functional theory. Favipiravir/Zn(12)O(12) (− 34.80 kcal/mol), Favipiravir/Mg(12)O(12) (− 34.98 kcal/mol), and Favipiravir/Be(12)O(12) (− 30.22 kcal/mol) were rated in order of drug adsorption degrees. As a result, Favipiravir attachment to (MgO)(12) and (ZnO)(12) might be simple, increasing Favipiravir loading efficiency. In addition, the quantum theory of atoms in molecules (QTAIM) assessment was utilized to look at the interactions between molecules. The FMO, ESP, NBO, and E(ads) reactivity patterns were shown to be in excellent agreement with the QTAIM data. The electrostatic properties of the system with the biggest positive charge on the M atom and the largest E(ads) were shown to be the best. This system was shown to be the best attraction site for nucleophilic agents. The findings show that (MgO)(12) and (ZnO)(12) have great carrier potential and may be used in medication delivery.
