The Biological Center of the Ministry of Science and Technology pointed out, at a press conference held on Feb. 15 by the Joint Defense and Control Mechanism of the State Council, that Chinese medical researchers have selected 5,000 drugs that may be effective from more than 70,000 drugs, and screened 100 drugs at the cell level to carry out in vitro tests. At present, they have focused on Chloroquine, Favipiravir and Remdesivir (Figure 1). A spokesman for the Biological Center of the Ministry of Science and Technology indicated that some drugs have shown good curative effects in clinical trials and stressed that Chloroquine, as a drug for sale, is safer.
