  • Title: [Spin-labeled nucleosides, nucleoside-5'-mono-, di-, and triphosphates].
    Author: Petrov AI, Sukhorukov BI.
    Journal: Biofizika; 1975; 20(6):965-6. PubMed ID: 173413.
    Abstract:
    A general method of synthesis of spin-labeled nucleosides, nucleoside-5'-mono-, di- and triphosphates is developed. It is based on the acyllation of ribose OH-group with N-(2,2,5,5-tetramethyl-3-carbonylpyrollin-1-oxyl)-imidasole. Their ESR and UV-spectra are studied. While studying the products of interaction between nucleoside mono-, di- and triphosphates and N-(2,2,5,5-tetramethyl-3-carbonylpyrrolin-1-oxyl)-imidasole along with the formation of monoradicals due to the acyllation of 2'(3')-OH-groups of ribose in the case of AMP, GMP and GDP acyllation by the phosphate group with the formation of biradicals has been also observed.
