Abstract
Objective: A unique liquid chromatography-mass spectrometry technique is essential for determining the concentration of asciminib in biological matrices, and its development is of the utmost importance. Methods: The samples that were processed were separated using a Reversed Phase-Phenomenex (100 mm x 4.6 mm, 5 µm) C18 analytical column. The column was equipped with an isocratic moveable phase that consisted of 0.1% (v/v) HCOOH and acetonitrile at a ratio of 18:82% (v/v). The flow rate of the phase was 0.70 ml/min. For asciminib, the multiple reaction monitoring mode was used at m/z 450.23/257.3, while for canagliflozin, it was used at m/z 445.13/267.31. Results: With a correlation coefficient of 0.9998, the method was linear for asciminib throughout the concentration range of 1.0-2100.00 ng/ml. Each day's accuracy percentage relative standard deviation was within 5.74%. For analytes at the low-quality control level, the mean matrix factors ranged from 96.34 to 104.85% with a % Coefficient of Variance (CV) of 4.21; at the high-quality control level, the range was from 94.62 to 103.88% with a %CV of 3.67. Conclusion: The method that has been developed has the potential to be used to examine the pharmacokinetics and toxicokinetics of asciminib in various biological samples for both forensic and clinical purposes.
