A new series of nucleoside derivatives was prepared from the reaction of 4-aminoantipyrene with different sugar moieties. In addition, ampyrone’s reaction with different aromatic aldehydes gave the corresponding Schiff base derivatives, which were also synthesized. Both molecular docking and in vitro antiviral activities at different concentrations of different synthesized compounds against SARS-CoV-2 were screened. All newly synthesized compounds were characterized on the basis of IR,  1 H NMR and  13 C NMR spectral data and physical data. The compounds were screened for potential cytotoxic activities. The molecular docking analysis showed that compounds 6b, 6e, 6c, 6f and 6d exhibited relatively higher binding energies (−8.1, −8.1, −8.3, −8.4 and −8.7 kcal/mol, respectively) compared to all the other compounds. However, the different compounds did not show any promising in vitro antiviral activities against SARS-CoV-2.
