   The cells were further incubated with a rabbit polyclonal antibody against a SARS-CoV nucleocapsid protein (Cambridgebio, USA) as primary antibody at a dilution of 1:200 for 2 h, followed by incubation with the secondary Alexa 488-labeled goat anti-rabbit antibody (Beyotime, China) at a dilution of 1:500.	SARS-CoV nucleocapsid protein suggested: (Creative Diagnostics Cat# DMAB8869, RRID:AB_2392503) anti-rabbit suggested: None

   The blot was probed with the antibody against the viral nucleocapsid protein (Cambridgebio, USA) and the horseradish peroxidase-conjugated Goat Anti-Rabbit IgG (Abcam, USA) as the primary and the secondary antibodies, respectively.	Anti-Rabbit IgG suggested: None

   Indirect immunofluorescence assay: Vero E6 cells were treated with CVL218 at 5 µM, 15 µM and 25 µM, respectively, following the same procedure of “full-time” treatment.	Vero E6 suggested: RRID:CVCL_XD71)

   Pharmacokinetics and toxicity study: Sprague-Dawley rats were purchased from Shanghai Laboratory Animal Center, China.	Sprague-Dawley suggested: RRID:RGD_70508)
   Software and Algorithms
   Sentences	Resources
   The virus target-drug interaction network was constructed from the integrated data from DrugBank (version 5.1.0) [17], ChEMBL (release 26) [54], TTD (last update 11 Nov, 2019) [55], IUPHAR BPS (release 13, Nov, 2019) [56], BindindDB [57] and GHDDI (https://ghddi-ailab.github.io/Targeting2019-nCoV/CoV_Experiment_Data/), with a cut-off threshold of IC50/EC50/Ki/Kd <10 µM.	DrugBank suggested: (DrugBank, RRID:SCR_002700) ChEMBL suggested: (ChEMBL, RRID:SCR_014042)
   The human protein-protein interaction network and the virus protein-human protein interaction network were constructed from the integrated data from BioGRID (release 3.5.181) [58], HuRI [59], Instruct [60], MINT (2012 update) [61], PINA (V2.0) [62], SignaLink (V2.0) [63] and innatedb [64].	BioGRID suggested: (BioGrid Australia, RRID:SCR_006334) MINT suggested: (MINT, RRID:SCR_001523) SignaLink suggested: (SignaLink, RRID:SCR_003569)
   Noted that we collected additional protein sequences of SARS-CoV-2 from UniProt [66] and added them into the corresponding networks for the final prediction.	UniProt suggested: (UniProtKB, RRID:SCR_004426)
   The training corpus we used was curated automatically from nearly 20 million PubMed (http://www.pubmed.gov) abstracts by a distant supervision technique [75].	PubMed suggested: (PubMed, RRID:SCR_004846)
   We used the connectivity map (CMap) [5], which contains the cellular gene expression profiles under the perturbation of 2428 well annotated reference compounds, to measure the associations of gene expression patterns between SARS-CoV infected patients and the reference compound-perturbed cells.	CMap suggested: (CMAP, RRID:SCR_009034)
   The dose-response curves were plotted according to viral RNA copies and the drug concentrations using GraphPad Prism (GraphPad Software, USA). 4.9.	GraphPad Prism suggested: (GraphPad Prism, RRID:SCR_002798)
   The plasma concentration-time data were analyzed using a non-compartmental method (Phoenix, version 1.3, USA) to derive the pharmacokinetic parameters. 4.14.	Phoenix suggested: (Phoenix, RRID:SCR_003163)
   The figures were prepared using GraphPad Prism (GraphPad Software, USA).	GraphPad suggested: (GraphPad Prism, RRID:SCR_002798)
   The statistical significance was calculated by SPSS (ver.12), and two values were considered significantly different if the p-value is < 0.05. 4.17.	SPSS suggested: (SPSS, RRID:SCR_002865)
   The AutoGrid program was used to generate a grid map with 60×60×60 points spaced equally at 0.375 Å for evaluating the binding energies between the protein and the ligands.	AutoGrid suggested: (Autogrid, RRID:SCR_015982)

   Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).
