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.
