For the treatment of various viral infections, antiviral drugs may be used.
Liquid chromatography-mass spectrometry (LC-MS) with tandem mass spectrometry
(MS-MS) operated in selected-reaction monitoring (SRM) mode is the method of
choice in quantitative bioanalysis of drugs, e.g., to establish bioavailability,
to study pharmacokinetics, and later on possibly for therapeutic drug monitoring.
In this study, the fragmentation in MS-MS of small-molecule antiviral drugs
against herpes and influenza viruses is reviewed. In this way, insight is gained
on the identity of the product ions used in SRM. Fragmentation schemes of
antiviral agents are also relevant in the identification of drug metabolites or
(forced) degradation products. As information of the fragmentation of antiviral
drugs in MS-MS and the identity of the product ions is very much scattered in the
scientific literature, it was decided to collect this information and to review
it. In this third study, attention is paid to small-molecule antiviral agents
used against herpes and influenza virus infections. In addition, some attention
is paid to broad-spectrum antiviral agents, that are investigated with respect to
their efficacy in challenging virus infections of this century, e.g., involving
Ebola, Zika and corona viruses, like SARS-CoV-2, which is causing a world-wide
pandemic at this very moment. The review provides fragmentation schemes of ca. 35
antiviral agents. The identity of the product ions used in SRM, i.e., elemental
composition and exact-m/z, is tabulated, and more detailed fragmentation schemes
are provided.
