    Inhibition Value Type:IC50
    Inhibitory Effect:0.025 ± 0.002
    Inhibitory Unit:µM
    Target Domain Name:HR2 domain of SARS-CoV
    Assay:Cell–cell fusion assay
    Assay Description:A dual-split-protein (DSP)-based cell-cell fusion assay was used to detect SARS-CoV-2 or SARS-CoV S protein-mediated cell-cell fusion activity and the inhibitory activity of the peptides, as described previously(PMID: 31619552). Briefly, a total of 1.5 × 10^4 293T cells (effector cells) were seeded in a 96-well plate and 1.5 × 10^5/ml 293T or 293T/ACE2 cells (target cells) were seeded in a 10-cm culture dish, and then the cells were incubated at 37°C. On the next day, the effector cells were cotransfected with an S protein-expressing and a DSP1–7 plasmid, the target cells were transfected with a DSP8–11 plasmid, and then the cells were incubated at 37°C. After 24 h, a serially 3-fold-diluted peptide was added to the effector cells and the cells were incubated for 1 h; the target cells were resuspended at 3 × 10^5/ml in prewarmed culture medium that contained EnduRen live cell substrate (Promega) at a final concentration of 17 ng/ml and incubated for 30 min. Then, 3 × 10^4 target cells were transferred to the effector cells and the mixture of cells was spun down to maximize cell-cell contact. After incubation for 2 h, luciferase activity was measured and IC50 values were calculated as described above.
