Antiviral drug Triazavirin, selectively labeled with 2H, 13C, and 15N stable isotopes. Synthesis and properties

Abstract

[Figure not available: see fulltext.] Isotope-labeled antiviral drug Triazavirin containing 2H, 13C, and 15N atoms in its structure has been synthesized. 13C2H3I and KS13CN served as donors of 13C isotopes. The use of 13С-MeI containing 2H atoms made it possible to additionally incorporate deuterium labels into the structure of the compound. The 15N atoms were incorporated using 15N-enriched sodium nitrite, aminoguanidine carbonate, and ethyl nitroacetate. The resulting 2H3,13C2,15N3-Triazavirin was characterized by NMR spectroscopy. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
