Abstract:

The aim of this study was to investigate the stereoselective effects of a popular pharmaceutical and personal care product component ibuprofen (IBU) on adult zebrafish using sphingolipidomics. Sphingolipidomics is an effective method developed to determine sphingolipids present in biological samples using ultra-high performance liquid chromatography-triple quadrupole linear ion trap mass spectrometry. Using this method, 46 sphingolipids in adult zebrafish brain samples were quantified after rac-/R-(-)-/S-(+)-IBU exposure, and the biomarkers were selected using chemometric approaches, including principal component analysis and orthogonal partial least squares discrimination analysis. Besides, combined with the results of the Duncan post hoc test and Dunnett post hoc comparison, sphingolipidomic perturbations were found to be induced after exposure to ibuprofen at environmental concentrations, and enantiomers of ibuprofen had stereoselective effects on zebrafish. This study may provide a new insight on the influence of ibuprofen on aquatic organisms.

Key words: enantiomers, ibuprofen, lipidomics, sphingolipid, ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS), zebrafish
