ABSTRACT: We
performed density functional theory (DFT) calculations for ribonucleotides and
active triphosphate metabolites of candidate drugs against Coronavirus disease
2019 (Covid-19). Frontier orbitals (highest occupied molecular orbital and
lowest unoccupied molecular orbital)
at optimized structure of each molecule were obtained. T-705RTP (active triphosphate
metabolite of favipiravir) and cytidine triphosphate (CTP) have similar shapes
of frontier orbitals. We also obtained similar shapes of frontier orbitals
among dihydroxy GS-441524 triphosphate (GS-441524 is an active triphosphate
metabolite of remdesivir) and adenosine triphosphate (ATP). From a theoretical viewpoint, we suggest T-705RTP is a CTP analogue
and dihydroxy GS-441524 triphosphate is an ATP analogue.
