<p><i>In silico</i> docking study
showed that hydroxychloroquine drug interactions with SARS-CoV2 show a higher
binding affinity with spike glycoprotein and PLPRO protein compared to protein
envelopes that could be ladder for potential targeting and synthesizing of
another aniviral drug. <i>In silico</i>
methods used in this study, the efficacy of a wide variety of repositioned
and/or novel drug candidates could also be tested prior to clinical evaluation.</p>
