Abstract

loxymethylthymine was the strongest inhibitor of the TP activity in endometrium, and 1-N-allyloxymethyl-4-hydrokxy-5-nitro-6-oxopyrimidine in endometrial cancer, respectively. The most potent activators of TP in endometrial cancer was 5-bromodeoxyuridine and 1-N-allyloxymethyl-5-nitrouracil, which increased the TP activity about 100%. 5-fluorodeoxyuridine, 5-jododeoxyuridine and 2’-deoxyuridine activated the TP in statistically significant manner too, but stronger in case of endometrial cancer than in normal endometrium. The synthesized 5-bromo-6-acetyloaminouracil strongly inhibited the TP activity of endometrial cells and might be useful in reducing endometrial cancer angiogenesis. On the other hand 5-bromodeoxyuridine and the synthesized 1-N-allyloxymethyl-5-nitrouracil might increase the effect of antitumor therapy with the cytostatics. These conclusions ought to be confirmed by analyzing more tumor cases.
