Abstract

Insights

A novel composite of layered double hydroxide (LDH) and metal-organic framework (MOF) efficiently extracts anti-cancer tyrosine kinase inhibitors (TKIs) from biological samples. This method offers a sensitive and rapid approach for bioanalytical monitoring.

Area of Science:

  • Analytical Chemistry
  • Materials Science
  • Pharmacology

Background:

  • Tyrosine kinase inhibitors (TKIs) require precise bioanalytical measurement in plasma and serum.
  • Efficient sample preparation is crucial to minimize matrix effects and enhance preconcentration for TKI analysis.
  • This study addresses the need for improved extraction and preconcentration techniques for TKIs.

Purpose of the Study:

  • To develop and validate a composite material for the extraction and preconcentration of specific TKIs.
  • To assess the efficacy of a layered double hydroxide (LDH) and metal-organic framework (MOF) composite for TKI analysis.
  • To provide a sensitive and efficient method for monitoring anti-cancer drugs in biological matrices.

Main Methods:

  • Synthesis of a composite material via in-situ growth of MIL-101(Cr)-NO2 MOF on a MgFe-LDH surface.
  • Extraction of sunitinib, imatinib, and dasatinib from plasma using the LDH/MOF composite under nitrogen blowing.
  • Analysis of extracted analytes using High-Performance Liquid Chromatography (HPLC) with a Photo Diode Array (PDA) detector.

Main Results:

  • The developed method achieved favorable extraction recoveries ranging from 66% to 74%.
  • Low limits of detection (LOD) and quantification (LOQ) were obtained (0.46-0.69 ng mL⁻¹ and 1.5-2.2 ng mL⁻¹, respectively).
  • The method demonstrated wide linear ranges (1.5-200 ng mL⁻¹) with high coefficients of determination (0.997-0.999) and good repeatability (RSD ≤ 6.6%).

Conclusions:

  • The LDH/MOF composite offers a high-performance method for monitoring anti-cancer drugs in biological samples.
  • The method utilizes minimal sorbent and solvents, requires short extraction times, and does not need complex instrumentation.
  • This approach presents a significant advancement in the bioanalytical challenges associated with TKI quantification.
