In this study, we propose a novel set of drug screening descriptors based on COSMO-RS σ-profiles, augmented by dipole moment and induced charge of the phosphorus atom, to evaluate the chemical similarity of the drugs with nucleotides, as RNA replication transcription initiation activators. A novel set of descriptors based on COSMO-RS σ-profiles and chemical thermodynamics is proposed and evaluated using PCA for the initial screening of a series of nucleotides and nucleotide-analog RdRp replication inhibitor drugs to help accelerate the discovery of COVID-19 treatments. The PCA results show that the novel σ-profile-based descriptor set I clearly correlates the leading COVID-19 drugs remdesivir and EIDD-2801 in monophosphate forms and highlights weaker correlations with drugs that have been reported to exhibit anti-SARS-CoV-2 activity. ./cache/cord-329318-eo8auo1f.txt ./txt/cord-329318-eo8auo1f.txt
