Our research group focuses on employing advanced mass spectrometry techniques, such as infrared ion (IRMPD) spectroscopy and ion mobility spectrometry (IMS), to evaluate reactive processes relevant to pharmaceutical and polymer chemistry. Polymerization reactions play a significant role in our economy, and understanding the intricate reaction pathways in these systems is crucial for developing new products to address societal challenges. To achieve this, we utilize mass spectrometry-based techniques to detect the species present in the reaction media, allowing for a deep insight into the reaction mechanism. Currently, our focus lies on studying polybenzoxazine and polyaniline resins.
In addition, we investigate the transformation products and metabolites of drugs, with a specific focus on assessing chemical reactive metabolites (CRMs) and their critical role in drug safety. During Phase I metabolism, numerous oxidative processes occur, generating many isomers that require identification. Advanced mass spectrometry techniques are indispensable for differentiating these isomers, especially when the dissociation pattern obtained by tandem MS is insufficient. Our primary interest in this field is to evaluate the suitability of these advanced techniques for detecting isomeric metabolites and transformation products without the need for previous chromatographic steps or analytical standards.
Currently, our main targets include relevant drugs used for the treatment of high blood pressure, such as metoprolol, and antineoplastic agents like cyclophosphamide and ifosfamide.
