dc.description.abstractHerein, we explored the synergistic effect of ionic liquids as anticancer and antibacterial agents to avoid available combination therapies. We synthesized an API-based ionic liquid (IL) designated as [Pro-pip]SAL to meet our objec tives. This compound features a cationic moiety derived from procaine and 1,3-benzodioxole, tagged with a salicylate salt as the anionic counterpart. Molecular docking studies showed that interaction is polar involving H-bonding and van der Waal forces. Spectroscopic studies were carried out to validate the results of computational studies for the binding interaction mechanism of [Pro-pip]SAL IL with bovine serum albumin (BSA). The UV–visible spectra showed an increase in absorbance intensity with bathochromic shift, and fluorescence spectra showed static quenching with bathochromic shift revealing that polar interaction played an important role in the interaction between Pro-pip]SAL IL with BSA. CD spectra showed no significant change in the secondary structure of BSA. The antibacterial study revealed that IL showed significant activity against Staphylococcus aureus (gram-positive) bacteria and no effect was observed on E. coli (gram-negative) bacteria. Cytotoxicity study on Vero cell line (non-cancerous cell line; kidney epithelium cells of African green monkey) showed IC50 values 207.95 ± 1.25 μM. Cytotoxicity analysis of [Pro-pip] SAL IL on A549 cell lines revealed antiproliferative properties with an IC50 value of 54.55 ± 0.22 μM. This study interpreted that Pro-pip]SAL IL could be used as an anticancer and antibacterial drug, warranting further exploration and development in these therapeutic areas.
