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

Biochemical pharmacology, 38(22), 3957-3962 (1989-11-15)
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
J M Te Koppele et al.
The Biochemical journal, 252(1), 137-142 (1988-05-15)
The stereoselectivity of purified rat GSH transferases towards alpha-bromoisovaleric acid (BI) and its amide derivative alpha-bromoisovalerylurea (BIU) was investigated. GSH transferase 2-2 was the only enzyme to catalyse the conjugation of BI and was selective for the (S)-enantiomer. The conjugation
