Implication

In vitro study reveals higher cytotoxicity of imidazolium ionic liquids than conventional solvents in human HeLa cells, highlighting risks of long alkyl chains.

Key Points

To evaluate the in vitro cytotoxicity of selected imidazolium ionic liquids on the human tumor cell line HeLa.
Assessed cytotoxicity across various 1-n-butyl-3-methylimidazolium entities paired with different anions using human HeLa cells in vitro.
Tested the effect of varying alkyl chain lengths, from ethyl to n-decyl, on cell toxicity.
Compared effect concentrations (EC50) of the ionic liquids directly to standard organic solvents, including dichloromethane, toluene, and xylene.
Cytotoxicity of 1-n-butyl-3-methylimidazolium depended strongly on the counter-anion, with tetrafluoroborate producing the lowest EC50 values.
Extending alkyl chain length to an n-decyl chain increased hydrophobicity and reduced EC50 by an order of magnitude compared to the n-butyl group, whereas methyl elongation to ethyl or n-hexyl had no direct effect.
Imidazolium ionic liquids exhibited lower effect concentrations in HeLa cells than conventional organic solvents like dichloromethane, toluene, and xylene.
