By the help of the High Throughput Core Facility of the Genome Center of the Academia Sinica, potential drugs with activity are screened out,the P3 laboratory conducts the antiviral cell experiment of the drug to accurately determine the effect of inhibiting the virus. In addition, the production process of the antiviral drug "Remdesivir" is improved,innovative preparation methods are proposed, which greatly increase the yield of "Remdesivir"effectively reduce the manufacturing cost.

We propose an AI dynamics drug repurposing platform applicate on COVID-19. This platform analyzed a large number of structures of SARS-CoV, MERS,cross-species coronavirus 3CL protease-ligand complexes to construct uncovering six flexible active site conformationspharmacophore clusters for SARS-CoV-2 3CL protease screening all FDA drugsfound four inhibitors within three months. Among them, JM206 had even demonstrated ten times better efficacy than Remdesivir in-vitro assayalso show the effect on the in-vivo hamster model to alleviate the symptoms caused by COVID-19.
