Degree-Based Graph Invariants of some Chemical Structures for the Treatment of Corona Virus by Shahid Amin, Haidar Ali, M. A. Rehman, Abd Allah A. Mousa, Mulugeta Andualem

“…A topological index (TI) is a mathematical function that assigns a numerical value to a (molecular) graph and predicts many physical, chemical, biological, thermodynamical, and structural features of that network. In this work, we will calculate a new topological index namely, atom-bond connectivity (ABC) index, Geometrically Arithmetic (GA) index, Sombor index, Multiplicative Sambor index, and its reduced version for the molecular graph of remdesivir (GS-5734), chloroquine, hydroxychloroquine, theaflavin, ritonavir, and arbidol. …”
