Autor: I. G. Akhmedzhanov, E. E. Gussakovskii, K. M. Ermolaev, T. A. Babaev
Publikováno v: Chemistry of Natural Compounds. 14:412-415
The results obtained show that when thyroglobulin is iodinatedin vitro the formation in it of thyroxine from the iodotyrosine residues present in it before iodination is possible. The structure of the thyroglobulin apparently plays an important role

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 8:2073-2083
A description is given of the synthesis of the semicarbazone of diethyl 2-methylene-3-oxo-1,1-cyclo-pentanedicarboxylate; a study was made of its transformations, which permit the preparation of various sarkomycin analogs. Treatment of this semicarba

Cleavage of arylhydrazones of ?-hydroxyketones at the N-N bond with acetic acid in the presence of O-phenylenediamine formation of quinoxalines
Autor: K. M. Ermolaev
Publikováno v: Chemistry of Heterocyclic Compounds. 7:504-506
The corresponding quinoxalines are formed by the reaction of arylhydrazones of α-hydroxyketones with o-phenylenediamine in glacial acetic acid. The basis for the reaction is the ability of arylhydrazones of α-hydroxycarbonyl compounds to undergo cl

[Modification of the spectrophotometric method of determination of pyridoxal-5'-phosphate and pyridoxal in enzymatic preparations]
Autor: M I, Turkov, K M, Ermolaev
Publikováno v: Prikladnaia biokhimiia i mikrobiologiia. 12(4)
In quantitative measurements of pyridoxal-5'-phosphate and pyridoxal in enzymes routinely used phenylhydrasine was substituted for 4-nitrophenylhydrasine. This increased the sensitivity of the method by 70%. The modified procedure had another advanta

[Oxidation of p-nitrobenzylamine and p-dimethylaminomethylbenzylamine by amine oxidases from the human placenta and serum]
Autor: A Z, Kirkel', Iu P, Romaniuk, G A, Davydova, K M, Ermolaev, V A, Pekkel'
Publikováno v: Voprosy meditsinskoi khimii. 32(2)
Oxidation of p-nitro- and p-dimethylaminomethyl derivatives of benzylamine, catalyzed by amine oxidases from human placenta and blood serum, was studied. The amine oxidase activity was estimated by means of a spectrophotometric procedure involving me
