Anthracycline assay by high-pressure liquid chromatography
Journal of Pharmaceutical Sciences
|March 1, 1981
Summary
A new method accurately measures anthracycline drug levels in plasma using high-pressure liquid chromatography and fluorescence detection. This analysis aids in studying drug metabolism and evaluating the clinical effects of doxorubicin analogs.
Area of Science:
- Analytical Chemistry
- Pharmacology
- Biochemistry
Background:
- Anthracyclines are crucial chemotherapy agents, but their clinical efficacy is limited by complex pharmacokinetics.
- Accurate quantification of anthracyclines and their metabolites in biological matrices is essential for understanding their behavior in vivo.
Purpose of the Study:
- To develop and validate a general analytical method for determining anthracycline concentrations in plasma.
- To enable further studies on anthracycline metabolism and clinical pharmacology.
Main Methods:
- Plasma samples were extracted using an organic solvent.
- High-pressure liquid chromatography (HPLC) on an aminocyanosilica column was employed for separation.
- Quantification was achieved by measuring the endogenous fluorescence of anthracyclines with intact tetracyclic ring structures.
Main Results:
- The method demonstrated sensitivity limits of 5 ng/ml for doxorubicin, 1 ng/ml for carubicin, and 5 ng/ml for marcellomycin.
- The assay successfully separated anthracyclines from their metabolites.
Conclusions:
- A robust and sensitive HPLC-fluorescence method for anthracycline analysis in plasma has been established.
- This assay is suitable for investigating enzymatic reactions involving anthracyclines and for evaluating the clinical pharmacology of doxorubicin analogs.
