(F and G) Additional dose-response curves were measured in primary human astrocytes for (F) EIDD-2749 and (G) GHP-88309 under the same MOI and assay conditions. (H) Summary of half-maximal inhibitory concentrations (IC 50 ) derived from the dose-response curves in (A–G). Each row indicates the respective compound, virus, calculated IC 50 , corresponding 95% confidence interval, and the cell type in which the assay was performed. IC 50 values were determined in GraphPad Prism by nonlinear regression of (inhibitor) vs. normalized response. All experiments were conducted in biological triplicate. Error bars depict standard deviation.

    VTA cells were infected with nanoluciferase-expressing SARS-CoV-2 WT or AA at 37°C at an MOI of 0.1 for 1hr after which input was removed, monolayers were washed and then exposed to a dose response of <t>5-fluorouracil</t> <t>(5-FU),</t> <t>β-d-N4-Hydroxycytidine</t> (NHC, EIDD-1931) or GS-441524 in Infection Media. Concurrently, non-infected cells were treated similarly to determine cytotoxicity. After 24hr, viral replication was assessed by NanoGlo Luciferase Assay System (Promega) and cytotoxicity was determined by CellTiterGlo Assay (Promega). Each condition was evaluated in triplicate in two independent studies. Values were normalized to the uninfected and infected vehicle DMSO controls (0 and 100% infection, respectively). Data were fit using a four-parameter nonlinear regression analysis using GraphPad Prism. EC50 and CC50 (cytotoxic concentration at which 50% of cells are viable) values were then determined as the concentration reducing the signal by 50%.
