Abstract
Antisense oligonucleotides (ASOs) have been widely investigated as a potential drugs because of their ability to bind with the target DNA or RNA strands, which may lead to inhibition of translational processes. This review presents currently approved oligonucleotide (OGN) drugs and summarizes their modification types, mechanisms of action, and application of ion pair reversed phase liquid chromatography for the analysis. Special attention was paid to the stationary phases selection for the separation of OGNs and the impact of different compositions of mobile phases on retention and signal intensity in mass spectrometry (MS). Moreover, the application of ion pair liquid chromatography coupled with MS for the separation and determination of metabolites of ASOs was described. The type of matrix, time of analysis, lower limits of quantification and detection, as well as precision, accuracy, and linearity of developed methods have been included as part of this contribution.
