Abstract:
Aims: In this work, some new chromeno[4',3'-b]pyrano[6,5-d]pyrimidines,3-amino and
3-methyl-5-aryl-4-imino-5(H)-chromeno[4',3'-b]pyrano[6,5-d]pyrimidine-6-ones derivatives were
synthesized.
Background: Chromenopyrimidines have attracted significant attention recently because of their
activities, such as antiviral and cytotoxic activity.
Objective: All synthesized compounds were characterized using IR, 1H-NMR, Mass Spectroscopy,
and elemental analysis data.
Methods: Molecular docking studies were carried out to determine the inhibitory action of studied
ligands against the Main Protease (6LU7, 6m03) of coronavirus (COVID-19). Moreover, the
Lipinski Rule parameters were calculated for the synthesized compounds.
Results: The result of the docking studies showed a significant inhibitory action against the Main
protease (Mpro) of SARS-CoV-2, and the binding energy (ΔG) values of the ligands against the
protein (6LU7, 6M03) are -7.8 to -9.9 Kcal/mole.
Conclusion: It may conclude that some ligands were likely to be considered lead-like against the
main protease of SARS-CoV-2.
