    Peptide Source:

    Human coronavirus OC43 (HCoV-OC43) : 31631

    Source Description:Peptide OC43-HR2P was derived from the HR2 domain of HCoV-OC43. EK0-1 was the optimized form of OC43-HR2P.
    Against Virus:

    Human coronavirus 229E (HCoV-229E) : 11137

    Inhibition Value Type:IC50
    Inhibitory Effect:0.30 ± 0.05
    Inhibitory Unit:µM
    Target Domain Name:HR1 domain of HCoV-229E
    Assay:Cell-cell fusion
    Assay Description:The inhibitory activity of a test peptide on HCoV S-mediated cell-cell fusion was determined. Briefly, effector cells (293 T/S/GFP) and target cells (Huh-7 cells) were cocultured in the presence or absence of a test peptide at the indicated concentrations for fusion. After counting the fused and unfused cells, the percentage of cell-cell fusion was calculated, as described above. The percent inhibition of cell-cell fusion was calculated using the following formula as described : [1 − (E − N)/(P − N)] × 100%. “E” represents the percentage of cell-cell fusion in the experimental group. “P” represents the percentage of cell-cell fusion in the positive control group, where 293 T/HCoV S/EGFP cells were used as effector cells, to which only PBS was added. “N” is the percentage of cell-cell fusion in negative control group, where 293 T/EGFP cells were used as effector cells. The IC50 was calculated using the CalcuSyn software provided by T. C. Chou. Samples were tested in triplicate, and all those experiments were repeated twice.
