Abstract
Background: Mobocertinib, an epidermal growth factor receptor tyrosine kinase inhibitor, is prescribed for the treatment of non-small cell lung cancer characterized by epidermal growth factor receptor exon 20 insertion mutations. The presence of impurities generated during its synthesis or storage may compromise the drug's efficacy and safety. Therefore, a comprehensive investigation of these impurities and the implementation of rigorous quality control measures are of paramount importance. However, robust analytical methods for the simultaneous and accurate detection of mobocertinib and its related impurities are currently lacking.
Methods: This study developed a novel reversed-phase high-performance liquid chromatography method (RP-HPLC) for separating and analysing mobocertinib and its impurities. An Agilent 5HC-C18 column (4.6 mm × 250 mm, 5 μm) was used to separate Mobocertinib and its related substances. The mobile phase composition, gradient elution program, and ultraviolet detection wavelength were optimized. Additionally, a new product (imp-A) was found during the forced degradation test. Its structure was elucidated by RP-HPLC, nuclear magnetic resonance (NMR) and high resolution mass spectrometry (HRMS). The biological activity of imp-A was preliminarily evaluated by methyl thiazolyl tetrazolium (MTT) assay.
Results: The RP-HPLC method developed in this study was validated in accordance with ICH guidelines, demonstrating satisfactory specificity, precision, stability, repeatability, accuracy, and robustness. The method exhibited good linearity over the concentration range of 0.1-20 μg mL-1. The limits of detection and quantitation for mobocertinib were determined to be 0.02 μg mL-1 and 0.05 μg mL-1, respectively. The structure of imp-A was successfully characterized, and its formation mechanism was elucidated. Furthermore, imp-A was found to inhibit the growth of various tumor cell lines.
Conclusion: The developed RP-HPLC method is suitable for the simultaneous detection of mobocertinib and its impurities, providing significant advantages for process development and quality control. Imp-A, a novel compound, demonstrated promising anticancer activity in vitro. However, further in vivo studies are required to fully assess its therapeutic potential, which may hold promise for clinical applications in cancer treatment.
期刊介绍：
Frontiers in Chemistry is a high visiblity and quality journal, publishing rigorously peer-reviewed research across the chemical sciences. Field Chief Editor Steve Suib at the University of Connecticut is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to academics, industry leaders and the public worldwide.
Chemistry is a branch of science that is linked to all other main fields of research. The omnipresence of Chemistry is apparent in our everyday lives from the electronic devices that we all use to communicate, to foods we eat, to our health and well-being, to the different forms of energy that we use. While there are many subtopics and specialties of Chemistry, the fundamental link in all these areas is how atoms, ions, and molecules come together and come apart in what some have come to call the “dance of life”.
All specialty sections of Frontiers in Chemistry are open-access with the goal of publishing outstanding research publications, review articles, commentaries, and ideas about various aspects of Chemistry. The past forms of publication often have specific subdisciplines, most commonly of analytical, inorganic, organic and physical chemistries, but these days those lines and boxes are quite blurry and the silos of those disciplines appear to be eroding. Chemistry is important to both fundamental and applied areas of research and manufacturing, and indeed the outlines of academic versus industrial research are also often artificial. Collaborative research across all specialty areas of Chemistry is highly encouraged and supported as we move forward. These are exciting times and the field of Chemistry is an important and significant contributor to our collective knowledge.
