Abstract
We studied the effects of some aniline and dioxaborininopyridine derivatives on the rate of oxidative deamination of putrescine and polyamines in a tissue with high mitotic index. These effects were evaluated quantitatively by measuring diamine oxidase and polyamine oxidase activities in a model cell-free test system of regenerating rat liver tissue. Aniline derivatives exhibited mainly antiproliferative effects and promoted oxidative degradation of putrescine, spermidine, and spermine. Dioxaborininopyridine derivatives inhibited this process, thus exhibiting carcinogenic properties.
Keywords:
diamine oxidase; polyamine oxidase; polyamines; spermidine; spermine.
