Figure Lengend Snippet: (a) Infection kinetics of RV-C15a-mGL in HeLa-CDHR3 C529Y mono29 cells at different MOIs and time points. Data are presented as mean ± SD (n=3). Selected MOI for antiviral assay is highlighted in green. (b) Pilot RV-C15a-mGL antiviral assay with reference compounds BF738735, Pirodavir, and Rupintrivir. Compounds were tested in 8-point dose-response assays starting at 1 µM. Assay plates were fixed at 3 dpi and analyzed by HCI. One representative plate is shown. Each point on the inhibition curves represents an individual replicate. Two operators performed the assay independently (total n=4). VC, virus control. CC, cell control. (c) Virus yield reduction assay with Rupintrivir and Vapendavir. Viral RNA in supernatants was quantified at 72 hpi. Data are mean ± SD (n=3). (d, e) Proof-of-concept inter-operator assay reproducibility across >300 plates containing pre-spotted reference compounds in assays with RV-A16, RV-B14, and RV-C15a-mGL. (f) Representative images of RV-C11a-mGL and RV-C41a-mGL infection and antiviral assays with Rupintrivir (n=3).
Article Snippet: Rupintrivir (Sigma-Aldrich PZ0315), BF738735 (MedChemExpress HY-U00426), Pirodavir (Sigma-Aldrich SML1818), and Vapendavir (Cayman 30546) were prepared as 10 mM DMSO stocks.
