Synthesis, crystal structure elucidation, DFT analysis, drug-likeness and ADMET evaluation and molecular docking studies of triazole derivatives: Binary inhibition of spike protein and ACE2 receptor protein of COVID-19

Abstract

The recent incidence of terrible acute respiratory syndrome coronavirus 2 (SARS CoV-2) has presently experienced some noteworthy mutations since its discovery in 2019 in Wuhan, China. The present research work focuses on the synthesis of three triazole derivatives (BMTPP, BMTTP, and BMTIP) and their inhibition activities against SARS-Cov-2 spike and ACE2 receptor proteins. The crystal structure for BMTTP was determined by the SCXRD method and optimized geometrical parameters for the three triazole derivatives were obtained by DFT calculations. HOMO-LUMO, Global reactive descriptors [GRD], and Molecular electrostatic potential (MEP) investigations exposed that all three compounds have biological properties. The drug-likeness ability of the synthesized compounds was examined using Molinspiration and a pre-ADMET online Server. Further, to explore the binding nature of three synthesized compounds with SARS-Cov-2 spike proteins/ACE2 receptor molecular docking studies were executed. The outcomes we obtained from molecular docking simulation studies suggest that the synthesized triazole derivatives may be well utilized as curing medicines against COVID-19. Ultimately, animal tests and precise clinical tests are required to prove the potent nature of these compounds against COVID-19. Finally, the present outcomes must be proved to utilize in-vitro and in-vivo antiviral methods.
