Two-photon photochemistry of nucleic acid components

Autor: E I Budovskiĭ, A M Tikhonova, L. B. Rubin, T N Men'shonkova, N A Simukova

Publikováno v: Soviet Journal of Quantum Electronics. 11:1602-1606

A study was made of the exposure of dilute aqueous solutions of nucleic bases and nucleosides to high-intensity ultraviolet radiation. It was established that such exposure results in destruction of bases and breaking of the N-glycoside bond. The ran

Reactivities of 1-mono- and 1,1?-bis-p-nitrophenylferrocenes and of 1,1?-diacetylferrocene

Autor: É. G. Perevalova, R. V. Golovnya, O. V. Starovsky, N. A. Simukova, A. N. Nesmeyanov

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 6:647-649

1. The introduction of acetyl and p-nitrophenyl groups into the ferrocene nucleus greatly reduces the ability of hydrogens of the ferrocene nucleus to undergo aromatic-substitution reactions (arylation with diazo compounds, mercuration, and acylation

[Products of laser photolysis of thymine and their transformation in chemical hydrolysis of polynucleotides to the bases]

Autor: D Iu, Iakovlev, O I, Koval'skiĭ, N A, Simukova, E I, Budovskiĭ

Publikováno v: Radiobiologiia. 24(5)

Some main products of laser photolysis and gamma-radiolysis of thymine were shown to undergo subsequent transformations during DNA hydrolysis by formic acid to the bases. The method has been developed for the quantitative determination of the charact
