In silico study: Assessment of the inhibition of cyclo-oxygenase 2 by ibuprofen by validating molecular docking and cardiovascular effects reported during the COVID 19 pandemic

Abstract

Introduction The Covid 19 pandemic has put the cardiovascular risk incurred when using nonsteroidal anti-inflammatory drugs at the heart of the discussion. Based on the information currently available, WHO does not recommend the use of ibuprofen. the objective is to evaluate the inhibition of cyclo-oxygenase 2 by ibuprofen by validating molecular docking. Method The crystallographic structure of ibuprofen bound to cyclooxygenase-2 was obtained from the Protein Data Bank (PDB) at a resolution <3.00 Å. The receiver was visualized using Discovery Studio Visualizer version 2.5.5. It was efficiently prepared using AutoDock / Vina software. The 3D structure of Ligand (Ibuprofen) was downloaded from the Drugbak database (https://www.drugbank.ca/): Accession number DB01050 Results Molecular docking was chosen as the first-line discrimination of the ibuprofen-COX2 intercation for the in silico study of putative competitors. The complex formed by Ibuprofen-COX 2 from the experimental model gives a docking score (Affinity: -7.3 (kcal / mol) with a mean square deviation of (RMSD = 23.884). Conclusion The evaluation of the inhibition of cyclo-oxygenase 2 by ibuprofen was validated by molecular docking. Cardiovascular effects already reported in patients treated with traditional non-steroidal anti-inflammatory drugs and coxibs have been observed in patients with COVID 19. Molecular docking becomes an essential step in drug discovery to explore other drug targets
