Summary
This study shows how to detect three related drugs, daunorubicin, doxorubicin, and epirubicin, using their unique light emission properties. A new method allows for their simultaneous measurement in mixtures with high accuracy.
Area of Science:
- Analytical Chemistry
- Photochemistry
- Biomedical Analysis
Background:
- Anthracyclines like daunorubicin, doxorubicin, and epirubicin are crucial in cancer therapy.
- Accurate quantification of these drugs in mixtures is essential for effective treatment and monitoring.
- Existing analytical methods may face challenges in simultaneously differentiating and quantifying these similar compounds.
Purpose of the Study:
- To develop a novel method for the simultaneous quantification of daunorubicin, doxorubicin, and epirubicin.
- To utilize room temperature phosphorescence (RTP) properties of their Europium(III) complexes for analytical purposes.
- To demonstrate the efficacy of Kalman filtering for analyzing time-resolved RTP data of these complexes.
Main Methods:
- Complexation of daunorubicin, doxorubicin, and epirubicin with Europium(III) ions.
- Measurement of room temperature phosphorescence (RTP) spectra and decay rates.
- Application of Kalman filtering for analyzing time-resolved RTP data.
- Development of an RTP optosensing method for simultaneous determination.
Main Results:
- Europium(III) complexes of the three anthracyclines exhibit useful RTP.
- While RTP spectra overlap, phosphorescence decay rates are distinct for each complex.
- Simultaneous quantification of all three complexes was successfully demonstrated.
- Analytical errors were within an acceptable range of +/- 5%.
Conclusions:
- Time-resolved RTP analysis combined with Kalman filtering enables differentiation and quantification of similar anthracyclines.
- The proposed RTP optosensing method offers a viable approach for simultaneous determination of daunorubicin, doxorubicin, and epirubicin in mixtures.
- This technique holds promise for improved analytical strategies in pharmaceutical and clinical settings.
