- Arsenic-containing lipids (arsenolipids) are natural products of marine organisms such as fish, invertebrates, and algae, many of which are important seafoods. A major group of arsenolipids, namely, the arsenic-containing hydrocarbons (AsHC), have recently been shown to be cytotoxic to human liver and bladder cells, a result that has stimulated interest in the chemistry and toxicology of these compounds. In this study, elemental laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) and molecular matrix-assisted laser desorption/ionization (MALDI-)MS were used to image and quantify the uptake of an AsHC in the model organism Drosophila melanogaster. Using these two complementary methods, both an enrichment of arsenic and the presence of the AsHC in the brain were revealed, indicating that the intact arsenolipid had crossed the blood-brain barrier. Simultaneous acquisition of quantitative elemental concentrations and molecular distributions could allow new insight into organ-specific enrichment and possibleArsenic-containing lipids (arsenolipids) are natural products of marine organisms such as fish, invertebrates, and algae, many of which are important seafoods.
