Binding analysis of SARS coronavirus main proteinase with HIV, psychotic and parasite drugs 2004-05-15 .txt text/plain 1566 87 58 To allow structure-based design of drugs directed at SARS-CoV main proteinase, we predicted its binding pockets and affinities with existing HIV, psychotic and parasite drugs (lopinavir, ritonavir, niclosamide and promazine), which show signs of inhibiting the replication of SARS-CoV. Except four drugs (lopinavir, ritonavir, niclosamide and promazine), we also conducted the docking studies of two other molecules, PNU and UC2, for their molecular formulas are close to those of niclosamide and promazine, respectively (Fig. 2) , and they both are the inhibitors of HIV-1 reverse transcriptase. Figure 3 displays the overall structures of docking for four drugs (lopinavir, ritonavir, niclosamide and promazine) and two inhibitors (PNU and UC2) to SARS-CoV main proteinase. Thus, the four drugs and two inhibitors studied here can basically bind to the active site of SARS-CoV main proteinase, a cleft between domains I and II. ./cache/cord-336605-d4loia11.txt ./txt/cord-336605-d4loia11.txt
