    ) Human ACE2-A549 cells were grown to confluency and infected at an MOI of 0.1 in either DMEM with 2%FBS and 0.05mg/ml gentamicin, or in the same media containing 0.01µM, 0.1µM, 1µM or 10µM NHC by allowing virus to adsorb to cells in a volume of 100µl for one hour at 37°C, and then topping up to 500µl with the relevant media afterwards.
    suggested: None
    Results In order to find the appropriate concentration range of NHC in hACE2-A549 cells, to investigate the effect on viral biology, Cell-titer Glo Assay (Promega) were used to measure % ATP production in cells.
    suggested: None

    Primer-trimmed bam files were further analysed using DiversiTools (http://josephhughes.github.io/DiversiTools/) with the “-orfs” function to generate the ratio of amino acid change in the reads and coverage at each site of protein in comparison to the reference SARS-CoV-2 genome (MN908947.3).
    suggested: None
    The absolute IC50 values were calculated using GraphPad Prism 9, using a non-linear 4-parameter logistic regression in a dose-response curve.

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    However, in-vitro systems have several limitations in comparison to live models of infection, so results should be interpreted with care, although the mechanism of action will be intra-cellular. Use of molnupiravir in a Syrian hamster model infected with SARS-CoV-2 resulted in a drop in viral load and reduced lung pathology compared to controls Treatment 12 hours post-infection resulted in a protective effect 12 but not at 24 hours post- infection. Further work is required to delineate the true treatment window of the drug in humans with mild to moderate disease. Anti-viral drugs are best given early in infection to reduce viral load. In-vivo ferret models have shown that severity is linked to the size of the viral inoculum18. Therefore, molnupiravir likely acts to reduce disease by reducing viral load in patients, and potentially subsequently reducing transmission. 10,12. One of the main benefits of molnupiravir as opposed to remdesivir is that it can be administered orally. However, as was seen with the Influenza anti-viral, Tamiflu, resistance to anti-virals can develop rapidly develop resistance is necessary, though it is likely that any adaptation for resistance will correspond with a reduction in fitness as seen with remdesivir 20. Use of molnupiravir would likely be most beneficial if used in combination with another treatment, preferably targeting a different part of the viral life cycle as has been used with success for HIV treatment. Finally, molnupiravir has broad ...

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
