Round 1

Reviewer 1 Report

The manuscript presented by Guo et al. describes that Suramin can be a drug candidate due to its ability to inhibit the interactions between NTDs of SARS-CoV-2  nucleocapsid protein and RNA. The manuscript is well written and scientifically sound. However, I have few concerns for authors which will be provided in the authors sections to make the manuscript better. I endorse the publication of this manuscript. 

1. Did Authors check the potency of Suramin in preventing SARS-CoV-2 infection? Any details would be interesting in this regard.

2. What is Suramin and what is its source? Can you provide a structure of this molecule that will be helpful for readers?

3. Is Suramin only specific for SARS-CoV-2 or can be used against other coronaviruses?

4. Which part of SARS-CoV-2 genome did you take the 16-mer RNA sequence and why only this sequence combination? Provide a reasoning.

5. In line, 104-107. How do you know the residue positions? Do you have a three dimensional structure? If yes, then why didn't you consider determining the structure of the NTDs and Suramin complex by NMR?

Reviewer 2 Report

The work exerted is so appreciated. A nice idea was discussed here. I was really impressed by it. Some little points need to be addressed before acceptance. So, a minor revision may be required to improve the manuscript.

1-      A reference drug is highly recommended (if Possible) to be included in the conducted in vitro and in silico investigations.

2-      The manuscript should include a separate section for “Conclusion”.
