Özet

The severe acute respiratory syndrome SARS-CoV-2 is the causative agent of COVID-19. Preventing binding of SARS-CoV-2 Spike glycoprotein to human ACE2 enzyme and inhibition of MPRO enzyme are still attractive drug targets for treatment of COVID-19 infection. Boron atom-containing compounds show anticancer, antibacterial, antiviral, antifungal, antiparasitic, anti-inflammatory, antituberculosis, anti-dermatophytic and anti-fertility activities. In the current study, the ADMET properties of ligands were calculated by the aim of SwissADME and pkCSM pharmacokinetics web tools. The results revealed that the ligands meet drug-likeness properties. Furthermore, we have performed molecular docking study of boron containing dioxaborepine and oxadiazaborole derivatives to investigate binding properties of ligands against SARS-CoV-2 Spike glycoprotein/ACE2 complex and inhibition of MPRO enzyme. Through the ligands a derivative of dioxaborepine showed best binding score against SARS-CoV-2 Spike glycoprotein/ACE2 complex with a binding score of -8.93 kcal/mol and a oxadiazaborole derivative exhibited a binding score value of -8.36 kcal which is the best binding ligand to the MPRO enzyme binding site. The analysis of binding poses of ligands and ligand-residue interactions of the systems revealed that dioxaborepines and oxadiazaboroles could have block binding of Spike glycoprotein to human ACE2 enzyme and could have inhibition effects on MPRO enzyme. This is the first study that boron containing dioxaborepine and oxadiazaborole derivatives are used to define inhibition properties of molecules against SARS-CoV-2 Spike glycoprotein/ACE2 complex and/or Main Protease. Furthermore, the ADMET properties of these molecules were investigated as in silico. Analyses indicate that a dioxaborepine derivative, d4o coded ligand has best inhibition properties for SARS-CoV-2 Spike glycoprotein/ACE2 complex with a docking score of -8.93 kcal/mol and an oxadiazaborole derivative, ligand coded as o4e has best inhibition properties for MPRO.image
