Abstract excerpt
Two nitroxyl spin label (NSL) compounds that are used experimentally as in vivo contrast enhancers in magnetic resonance (MR) imaging were tested for acute toxicity in rats and for genotoxic effects in cell cultures. These compounds, 2,2,5,5-tetramethyl-1-pyrrolidinyl-oxy-3-carboxylic acid (PCA)...
