Metabolism:
Many enzymes exhibit stereoselectivity, a preference for one or the other enantiomeric form:
In the case of drug-metabolizing enzymes, stereoselectivity may result in a difference in the duration of action of one enantiomer compared to the other.
Structure Activity Relationships:
Understanding the relationship between drug structures and biological activities forms the basis of rational drug design.
Computer-enhanced molecular modeling and information concerning three-dimensional receptor structure may combine to improve the effectiveness of rational drug design approaches.
