Inhibition of CVB3-induced CPE by jiadifenoic acids C. Confluent Vero cultures were inoculated with 100 TCID₅₀ CVB3 (Nancy). After 1 h of adsorption at 37 °C, the monolayers were washed with PBS and incubated at 37 °C in the maintenance medium (MEM plus 2% FBS) with or without various concentrations of jiadifenoic acids C. The morphological changes in Vero cells were observed until the CPE of the control group cells reached 4.
