Kinetic isotope effects in the enzymic reactions of tritium- and deuterium-containing substrates
Autor: G P Akulov
Publikováno v: Russian Chemical Reviews. 61:999-1008
The kinetic differences between the enzymic reactions involving substrates containing heavy hydrogen isotopes are examined. Theoretical estimates and numerous examples of experimentally measured kinetic isotope effects in various enzymic reaction are

Solid-phase catalytic isotope exchange of alkylxanthines with gaseous tritium
Autor: Ju. L. Kaminski, N. A. Patokina, G. P. Akulov, S. G. Rosenberg
Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 31:759-762
The results of the synthesis of 11 different tritiated alkylxanthines by solid-phase catalytic isotope exchange are described. 3H-NMR analysis of the labelled compounds shows that in contrast to liquid-phase isotope exchange the tritium label is inco

Preparation of tritium-labelled dextran and inulin
Autor: G. P. Akulov, B. K. Kudelin, Ju. L. Kaminski, N. A. Korsakova
Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 31:227-230
Tritiated dextran and inulin were prepared by both a catalytic solid state and a liquid phase isotope exchange with gaseous tritium. The liquid phase procedure is convenient for preparation of the polysaccharides with specific activities up to 5 mCi/

Tritium labelling of polyols
Autor: B. K. Kudelin, E. V. Snetkova, Ju. L. Kaminski, G. P. Akulov, V. L. Efimova
Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 29:1351-1353
Mannitol, galactitol and myo-inositol were labelled by a solid state isotope exchange with gaseous tritium. The labelled polyois were prepared with specific activities in the range 740–4440 TBq/mol (20–120 kCi/mol) after purification by HPLC.

Synthesis of uridine diphosphate [1-3H]glucose and uridine diphosphate [6-3H]glucose
Autor: L. S. Gordeeva, Yu. L. Kaminskii, E. V. Snetkova, G. P. Akulov
Publikováno v: Chemistry of Natural Compounds. 23:105-108
Information is given on the synthesis of tritium-labeled UDPG by the successive transformation of D-[1-3H]glucose or D-[6-3H]glucose by the action of the enzymes hexokinase (EC 2.7.1.1), phosphoglucomutase (EC 2.7.5.1), and UDPG-pyrophosphorylase (EC

Introduction of a tritium label into nucleoside analogs modified in their carbohydrate residues
Autor: G. P. Akulov, R. Z. Zhuk, A. I. Nagorskii, Yu. L. Kaminskii, N. A. Patokina, L. A. Yakovleva
Publikováno v: Chemistry of Heterocyclic Compounds. 24:79-83
The synthesis has been effected of arabinofuranosylcytosine, -uracil, and -adenine, and of ftorafur [tegafur] and acyclovir, all containing a tritium label. The introduction of tritium was effected by reductive dehalogenation and desulfuration and al
