Structural aspects of molnupiravir complexed with the RNA SARS-CoV-2 virus have been recently resolved inside RNA-dependent polymerase (RdRp), demonstrating interactions purine nucleosides. However, preference to interact one nucleoside over another has not clearly investigated. Herein, complexation in its active form guanosine and adenosine was compared, using sundry density functional theory calculations. The plausible tautomeric structures drug complex guanosine/adenosine were minutely scrutinized. relative energy findings outlined favorability amino-molnupiravir···keto-amino-guanosine imino-molnupiravir···amino-adenosine optimized complexes. According interaction (Eint) binding (Ebind) values, higher preferential base-pairing recognized Eint/Ebind values -31.16/-21.81 -13.93/-12.83 kcal/mol, respectively. This could be interpreted by presence three two hydrogen bonds within former latter complexes, Observable changes electronic properties global indices reactivity studied complexes also confirmed from quantum atoms molecules noncovalent index support partially covalent nature investigated interactions. For both thermodynamic parameters spontaneous, exothermic, nonrandom states inspected Inspecting solvent effect on more observable amelioration water medium compared gas one. These results would a durable ground for forthcoming studies concerned

The nucleoside analog β-D-N4-hydroxycytidine is the active metabolite of prodrug molnupiravir and accepted as an efficient drug against COVID-19. Molnupiravir targets RNA-dependent RNA polymerase (RdRp) enzyme, which responsible for replicating viral genome during replication process certain types viruses. It works by disrupting normal function RdRp causing it to make mistakes genome. These can prevent from being transcribed, converted into a complementary DNA template, translated, or functional protein. By these crucial steps in process, effectively inhibit virus reduce its ability cause disease. This review article sheds light on impact SARS-CoV-2 variants concern, such delta, omicron, hybrid/recombinant variants. detailed mechanism molecular interactions using docking dynamics have also been covered. safety tolerability patients with comorbidities emphasized.
