Disclosed in the present invention are an anti-SARS-CoV-2 arylnaphthalene
lignan compound, and a preparation method therefor and the use thereof. Results show that ANL-1, ANL-2, and ANL-4 to ANL-7 have no
toxicity to Vero E6 cells, and ANL-3 has
low toxicity to Vero E6 cells. In a Vero E6
cell model, the
in vitro anti-SARS-CoV-2 activities of ANL-7 and ANL-2, in TI value, are respectively 19 times and 16 times that of remdesivir, and are higher than the in-vitro anti-SARS-CoV-2 activity of a market-available
drug. ANL-2 has a significant
inhibitory effect on
RNA-dependent RdRp activity of SARS-CoV-2, and ANL-2 also effectively limits the replication of various pathogenic coronaviruses in Caco2 cells or hamsters. It can be seen that the arylnaphthalene
lignan compound has a good anti-
coronavirus activity and can be used for treating and preventing SARS-CoV-2 infection or delaying the progress of SARS-CoV-2 infection in a patient.
