Enantiospecific analysis: applications in bioanalysis and metabolism

Area of Science:

• Pharmaceutical Chemistry
• Analytical Chemistry
• Biotechnology

Background:

• Enantiospecific analysis is vital for drug development, ensuring the efficacy and safety of chiral drugs.
• Chromatographic techniques, including chiral derivatizing agents and chiral stationary phases, are standard methods for separating enantiomers.
• Limitations of current chromatographic methods necessitate exploration of alternative analytical approaches.

Purpose of the Study:

• To compare the advantages and limitations of chiral derivatizing agents versus chiral stationary phases in chromatographic enantiospecific analysis.
• To evaluate the potential of biosensors as a novel tool for enantiospecific analysis.
• To present preliminary findings on an enantioselective biosensor for (S)-warfarin detection.

Main Methods:

• Comparative analysis of two chromatographic approaches: chiral derivatizing agents and chiral stationary phases.
• Application of these methods to representative chiral compounds: 2-arylpropionic acids (ibuprofen, tiaprofenic acid) and chiral N-oxides.
• Development and preliminary testing of an enantioselective biosensor.

Main Results:

• Established the strengths and weaknesses of both chiral derivatizing agents and chiral stationary phases for specific compound classes.
• Demonstrated the feasibility of using chromatographic techniques for analyzing target enantiomers.
• Showcased initial promising results for an enantioselective biosensor, indicating its potential utility.

Conclusions:

• Chromatographic methods remain essential but have inherent limitations in enantiospecific analysis.
• Biosensors offer a promising alternative or complementary technology for future enantiospecific drug analysis.
• Further development of enantioselective biosensors could significantly impact drug development and quality control.
