Capecitabine Analysis Service

Capecitabine Analysis Service

Empowering Precision with Capecitabine Analysis

Capecitabine is an oral fluoropyrimidine nucleoside metabolic inhibitor anticancer agent. Capecitabine is broken down in the body to produce substances that interfere with the production of DNA, RNA, and proteins, thereby affecting the growth of cancer cells and other fast-growing cells. Thus, capecitabine is a useful PharmaceuticalCD BioGlyco provides comprehensive identification services for capecitabine and its metabolites. Moreover, we offer fundamental analytical services.

  • Fundamental analysis
    • Solubility test: We test the solubility of capecitabine in various solvents such as methanol, acetonitrile, ethanol, and water.
    • Specific rotation test: Our researchers accurately weigh a small number of samples dissolving in methanol and measure their specific rotation after quantitative dilution.
    • Identification: We compare the plots of samples and standards by high-performance liquid chromatography (HPLC) and infrared spectroscopy. Their liquid phase retention times and spectral characteristic peaks are analyzed one by one. Combining HPLC and mass spectrometry (MS), we perform high-quality analysis of capecitabine and impurities in the samples. Moreover, we provide capecitabine metabolite and impurity characterization services.
    • Others: We provide moisture testing in samples, analysis of residual solvents, and analysis of heavy metals in incandescent residues.
  • Capecitabine-loaded vehicle analysis
    • We provide characterization services for capecitabine binding vehicles (e.g. microsphere, copolymer). We measure their in vitro drug release efficiency, cytotoxicity, etc.
  • Pharmacokinetic analysis
    • Our researchers provide physiological pharmacokinetic (PBPK) modeling services for capecitabine and its metabolites, with detailed analysis of pharmacokinetics in animal model tumors and plasma. Moreover, we analyze the expression of the protein in the cells before and after drug administration.

Publication Data

Technology: HPLC, Pharmacokinetic analysis

Journal: Saudi Pharmaceutical Journal

Published: 2022

IF: 4.562

Results: Researchers used acetonitrile precipitation to extract capecitabine and its metabolites from plasma. The pharmacokinetics were determined after separation by HPLC. Results showed that the monitoring data for the lower dose administration was similar to that of normal administration, and the half-life was significantly longer for the lower dose.
