Sažetak

Copanlisib is a pan phosphatidylinositol 3-kinase (PI3K) inhibitor approved for follicular lymphoma. In this paper, we present the data of development and validation of a high-performance liquid chromatography (HPLC) method for the quantitation of copanlisib in mice plasma as per the FDA regulatory guideline. The method involves the extraction of copanlisib along with internal standard (IS, enasidenib) from mice plasma (100 µL) using ethyl acetate as an extraction solvent. The chromatographic resolution of copanlisib and the IS was achieved on a Hypersil Gold C18 column maintained at 40 °C using a binary gradient mobile phase [10 mM ammonium formate (pH 4.0) and acetonitrile]. The flow-rate was 0.8 mL/min. For the detection of copanlisib and the IS, the photo-diode array detector was set at λmax 310 nm. Copanlisib and the IS eluted at 6.60 and 7.80 min, respectively with a total run time of 10 min. The calibration curve was linear over a concentration range of 50 to 5000 ng/mL for copanlisib (r2 0.998). The results of intra- and inter-day accuracy and precision studies were within the acceptable limits. Copanlisib was stable on bench-top, in auto-sampler, up to three freeze/thaw cycle and long-term storage at -80 °C. The application of the validated method was shown in a mice pharmacokinetic study.
