WebMay 4, 2009 · To complicate matters, chiral selection can be short-circuited and efficacy and toxicity data misinterpreted if a drug undergoes chiral inversion—the conversion of one enantiomer into its opposite (e.g., Fig. 7B) (Ali et al., 2007; Wsol et al., 2004). In vivo, this normally occurs with the assistance of an enzyme catalyst.
