Schizophrenia is one of the most debilitating and costly illnesses worldwide. First-generation antipsychotics such as chlorpromazine and haloperidol succeeded in controlling the positive symptoms of schizophrenia, but had significant extrapyramidal effects that led to the search for new agents and the release of second-generation (or atypical) antipsychotics. These drugs had a lower risk of adverse motor symptoms. Therapeutic drug monitoring has become a useful tool to optimize schizophrenia treatment and HPLC-MS/MS has been considered the primary technique to monitor antipsychotics. This review comprises three sections: schizophrenia pathophysiology and treatment; recent advances in LC-MS/MS methods designed to measure levels of antipsychotics and their metabolites in plasma samples (selectivity, matrix effect and sensitivity); and the importance of therapeutic drug monitoring.

The composition of the injection solvent is a critical, yet often underestimated, parameter in liquid chromatography-tandem mass spectrometry (LC-MS/MS). This study systematically evaluates the influence of injection solvent on the analysis of 90 pesticides by comparing mixtures of acetonitrile (ACN) with water and buffered mobile phase A (5 mM ammonium formate, 0.1% formic acid) across various ratios (10/90 to 50/50, v/v).

Tri-OPEs have become significant aquatic contaminants owing to their large production volumes and wide range of applications. Organophosphate diesters (di-OPEs) are closely related to tri-OPEs.

Antibody-drug conjugates (ADCs) represent a rapidly expanding class of therapeutics, uniquely combining the specificity of monoclonal antibodies with the potency of cytotoxic small-molecule payloads. Due to their inherent structural complexity and heterogeneous composition, accurate characterization and quantification of ADCs pose significant bioanalytical challenges. This review discusses recent advancements in bioanalytical methodologies, including ligand binding assays (LBAs), liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based approaches, and emerging hybrid LBA-LC-MS/MS platforms.

Pomegranate processing generates large quantities of pomace and mesocarp, yet their carbohydrate composition remains largely unexplored. Here, we applied comprehensive mass spectrometry-based profiling to characterize monosaccharides, oligosaccharides, and polysaccharides from these side streams. Fructose and glucose dominated the free sugar fraction in both tissues.

Aims: Risdiplam is a small molecule approved for the treatment of spinal muscular atrophy (SMA). The drug and its major metabolite had to be measured in plasma and tissue from several animal species and in human plasma and urine. Bioanalytical challenges including light sensitivity, instability, carryover, nonspecific binding, and complex tissue analysis, had to be overcome.
