Abstract
A graphical index is a numeric value corresponding to a structurally invariant graph, and in molecular graph theory, these invariants are known as topological indices. In the field of Chemical and Medical Sciences, the topological indices are used to study the chemical, biological, medical, and pharmaceutical features of drugs. Concerning the previous deadly diseases, the COVID-19 pandemic has been considered the biggest life-threatening issue that modern medicines have ever tackled. COVID-19 is immedicable, and even the existing treatments are only helping a certain group of sufferers. Scientists have tested available antiviral agents and got a favorable impact on recovering from the pandemic. Some of these antiviral agents are remdesivir, chloroquine, hydroxychloroquine, theaflavin, and dexamethasone. Keeping given the importance of topological indices in the study of pharmaceutical and chemical drugs, in this paper, we calculate the reduced neighborhood topological indices and RNM-polynomial of some of the antiviral agents remdesivir, chloroquine, hydroxychloroquine, theaflavin, and dexamethasone. The results thus obtained may be useful for finding new medicine and vaccine for the treatment of COVID-19.
