Application of alternative electron-based fragmentation for identification of drug metabolites and quantification of complex peptide therapeutics

Application of alternative electron-based fragmentation for identification of drug metabolites and quantification of complex peptide therapeutics

Throughout drug development, it is important to characterize and quantify pharmaceutical compounds and any associated metabolites to ensure proper drug safety and efficacy. LC-MS/MS techniques are predominantly used for such analyses because they provide a comprehensive outlook and can offer a sensitive and selective approach for the quantification of compounds. However, limited deep fragment coverage and sensitivity challenge the confident identification and quantification of metabolites and drug products. Here, alternative fragmentation paired with a highly sensitive QTOF system was employed for comprehensive data collection to properly identify metabolites and quantify complex peptide therapeutics.
