ABSTRACT A novel synthetic reaction was used to produce a piperidine derivative, specifically N′-(1-benzylpiperidin-4-ylidene)furan-2-carbohydrazide (BPFC). The structure of the synthesised compound was confirmed through FT-IR, 1H-NMR and 13C-NMR spectral analysis. DFT calculations were performed to optimise structural parameters and investigate Natural Bond Orbital (NBO) analysis, Frontier Molecular Orbitals (FMOs), Molecular Electrostatic Potentials, Mulliken Charge Analysis, and Non-linear Optical properties. The predicted chemical shift values align well with the expected results. The antioxidant properties of the newly synthesised compound were assessed using DPPH, ABTS, and H2O2 radical scavenging assays. Molecular docking studies were also carried out to explore the binding mechanism of the compound with COVID-19-related proteins, particularly 6WCF and 6LU7. Additionally, the synthesised compound was assessed for drug-likeness and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) properties, revealing favourable pharmacokinetic profiles without any signs of toxicity.
