Inactivation of viral infections by CHLA and PUG. Different viruses were treated with the test compounds for a long period (incubated for 1.5 – 3 h before titration; light gray bars) or short period (immediately diluted; dark gray bars) at 37°C before diluting it 50 – 100 fold to sub-therapeutic concentrations and subsequent analysis of infection on the respective host cells. (A) Schematics of the experiment (shown on the left) with the final virus concentration (PFU/well or MOI), long-term virus-drug incubation period (i), and the subsequent incubation time (ii) indicated for each virus in the table on the right. Analyses for (B) HCMV, (C) HCV, (D) DENV-2, (E) MV, and (F) RSV are indicated in each additional panel. Results are plotted against the DMSO negative control treatment for virus infection and the data shown are the means ± SEM from three independent experiments. See text for details.
