Unveiling the anticancer potential: Exploring 4-fluoro benzoic acid and piperazine through spectroscopic, X-ray diffraction, DFT and molecular docking analysis

The crystalline substance formed from piperazine and 4-fluorobenzoic acid (PZ-PFBA) was successfully synthesized. This synthesis involved the transfer of protons between the selected acid and base, resulting in the formation of distinct crystalline salt. The SCXRD analysis conforms the salt crystallized in a monoclinic crystal system with a P 21/c space group and lattice parameters are a = 13.0688(14) & Aring;, b = 8.2686(8) & Aring;, and c = 8.2552 (9) & Aring;. Hirshfeld surface analysis, a technique for quantifying molecular interactions, was employed to investigate the prepared crystalline salt. Additionally, the salt was subjected to further examination using FT-IR, 1H NMR, 13C NMR, and SCXRD studies. The crystalline salt has major and established biological actions that inhibit the human lung cancer cell line A549. In vitro, and Insilico anticancer tests show that PZ-PFBA has better efficacy against the human cervical cancer cell line (HeLa) and in bioinformatics analysis. PZ-PFBA demonstrated more efficacy in reducing pathogenic strains compared to its parent reactants.
