Objective To determine anti-viral activities of three Artocarpus species: Artocarpus altilis, Artocarpus camansi, and Artocarpus heterophyllus (A. heterophyllus) against Hepatitis C Virus (HCV). Methods Antiviral activities of the crude extracts were examined by cell culture method using Huh7it-1 cells and HCV genotype 2a strain JFH1. The mode of action for anti-HCV activities was determined by time-of-addition experiments. The effect on HCV RNA replication and HCV accumulation in cells were analyzed by quantitative reverse transcription-PCR and western blotting, respectively. Results The dichloromethane (DCM) extract of A. heterophyllus exhibited strong anti-HCV activity with an inhibitory concentration (IC
