Abstract:
:The polarographic reduction of six synthetic 1,3,6-triazine (6-aza) nucleosides with 6-azauracil as the nucleoside base in the strictly anhydrous solutions was studied in the absence and presence of alpha-lipoic acid. The values of the half-wave potentials E1/2 and the parameter of potential carcinogenicity tg alpha were compared for six nucleosides of 6-azauracil and two nucleosides of 4-thio-6-azauracil. The current value of the first diffuse polarographic wave or a new diffuse polarographic wave belonging to the nucleoside-alpha-lipoic acid complex increased with the increase of the alpha-lipoic acid concentration for the all compounds only marginally. Although this diffuse current increase was linear and dependent on the alpha-lipoic acid concentration in anhydrous solutions, the determined index tg alpha values ranged between 0.027 and 0.114. This is an indication of a very low potential carcinogenicity of the all nucleoside analogues investigated.
