Summary:
The preparation of pure individual enantiomers represents a topical problem from the standpoint
of efficacy and safety of drugs. This paper continues in the prececding review of the blockers of
β-adrenergic receptors as a group of chiral drugs, which is concerned with different pharmacodynamic,
pharmacokinetic, and toxicological effects of individual enantiomers of this group. The review
paper pays attention to the problems of enantioseparation of this group of chiral drugs, listing
individual examples of the methods of enantioseparation, such as crystallization, biocatalysis,
chromatographic methods (HPLC, GC, TLC), capillary electrophoresis, and the method of nuclear
magnetic resonance (NMR). The individual methods of enantioseparation including enantioseparation
in biological material (urine, serum) are illustrated on examples on β-blockers used in clinical
practice (e.g., propranolol, atenolol, metoprolol) as well as potential agents of this group of drugs.
Key words:
β-blockers – enantioselective biocatalysis – crystallization –
chromatographic separation – capillary electrophoresis
– nuclear magnetic resonance
