[Experimental study of radiosensitizing effect of analogs of purines and pyrimidine bases in cultured HeLa cells].

The radio-sensitizing capacity of cultured HeLa cells was investigated by using a number of compounds, which are analogues of purine and pyrimidine bases. Agents (5-fluorouracil, ftorafur, mercaptopyrine) used in chemotherapy for tumors for many years and some compounds (allopurinol and theophylline) that are sterically close to purine and pyrimidine bases… CONTINUE READING
