| | Inhibitory Effect on SARS-COV-2 Infection |
| Description: | In order to confirm the inhibitory effect of the novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one derivatives against SARS-COV-2 infection, the Vero cell line was cultured for 24 hours, dosed with example compounds at ten concentrations ranging from 0.1 micro M (micro gram) to 50 micro M, and infected with the SARS-COV-2 provided from the Korea Centers for Disease Control and Prevention (KCDC). Specifically, the Vero cells were seeded at 1.2×104 per well into a 384-well tissue culture plate. On the next day, the compound at a concentration of 50 micro M was serially diluted two-fold to prepare compounds at ten concentrations and treated with Vero cells. Soon after, the cells treated with the compound were infected with SARS-COV-2 (COVID 19) and cultured at 37° C. for 24 hours. Then, the cells were fixed and permeabilized. After that, the cells were treated with anti-SARS-COV-2 Nucleocapsid (N) primary antibody and then stained by treatment with Alexa Fluor 488-conjugated IgG secondary antibody and Hoechst 33342. Fluorescent expression was obtained using an Operetta large image analyzer (Perkin Elmer). |
