The joint research team published new evidence that Saquinavir and Lopinavir can suppress SARS-CoV-2. Both drugs can inhibit the activity of NSP16 methyltransferase, thereby suppressing the function and replication of the virus.

Methods

· We have built three large-scale drug screening libraries. The first library uses DrugBank, which contains 8,506 small molecular drugs. The second uses the 2.24 million lead-like small molecular compounds in the ZINC database. The third uses the 160 million small molecular drugs of UniChem.

· The structure of the SARS-CoV-2 NSP16 protein we used was derived from protein homology modeling and molecular dynamics simulation.

· With the help of the HUAWEI CLOUD AI Ascend cluster service and the EIHealth drug R&D platform, we completed large-scale virtual screening of the NSP16 target protein in the DrugBank screening library within 20 minutes. The following shows the result.

· The screening results of other target proteins will be released later.
