Abstract

The conclusive diagnosis of neurodegenerative diseases, such as Parkinson's disease (PD) and Alzheimer's disease (AD), has been predominantly clinical and, in these cases, the neurodegeneration is already installed in the patient's brain. Therefore, efforts have been made to identify molecular biomarkers for early diagnosis and monitoring these neurodegenerations progression. High performance liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) has been considered a reference analytical technique for the determination of biomarkers in biological fluids. Due to complexity of biological fluids, LC-MS/MS methods require a sample preparation step to exclude the biological matrix macromolecules and to concentrate the analytes (trace levels). The sample preparation techniques have been simplified, miniaturized (lower sample and organic solvent consumption), and/or hyphenation with chromatographic systems, automation (high-throughput performance). In this context, we can highlight the salting-out assisted liquid-liquid microextraction (microSALLE) and in-tube microextraction (in-tube SPME) hyphenated with LC-MS/MS. The development of capillaries with innovative bifunctional stationary phase for in-tube SPME, such as organic monolithic phases combined with restricted access materials (RAM) and polymerizable zwitterionic ionic liquids (ZILs) has allowed selective pre-concentration of the analytes. In this project, for the evaluation of potential biomarkers for DA, the following methods will be developed for the determination of AD biomarkers in plasma and cerebrospinal fluid samples: (a) in-tube SPME-LC-MS/MS using a organic monolithic capillary with sulfonic groups with RAM covering for the determination of ²-amyloid peptides, (b) in-tube SPME-MS/MS using a polyester(ether)ketone (PEEK) capillary packed with nitinol fibers (SPME support) coated with ZILs for determination ²-amyloid peptides and (c) in-tube SPME-LC-MS/MS using a organic monolithic capillary with cation-exchange groups with RAM covering for determination of homocysteine and homocysteic acid. For the evaluation of PD biomarkers, the microSALLE/LC-MS/MS method will be developed for the determination of anandamide (AEA) and 2-arachidonoylglycerol (2-AG) in parkinsonism-induced rats treated or not with levodopa (L-Dopa). Therefore, in agreement with the state-of-the-art of the miniaturized sample preparation and separation techniques, this project is noteworthy in the field of neuroscience. (AU)
