Glutathione (GSH) conjugation of the separate enantiomers of five 2-bromocarboxylic acids and some of their urea derivatives by rat liver GSH transferases (GSTs) was studied. The liver cytosolic fraction conjugated all compounds, except for (R)-2-bromoisovaleric acid, with a variable degree

The glutathione (GSH) conjugation of (R)-and (S)-alpha-bromoisovaleric acid (BI) in the rat in vivo, and its stereoselectivity, have been characterized. After administration of racemic [1-14C]BI two radioactive metabolites were found in bile: only one of the possible diastereomeric BI-GSH conjugates
