摘要

The changes in the PMR spectra of purine bases added to aqueous solutions (D2O) of antibiotics of the pyrimido[5,4-e]-1,2,4-triazine type, reumycin and xanthotricin as well as the changes in the PMR indicate formation of heteroassociates with batch structure as a result of stacking interaction. Chemotherapeutic effect of the antibiotics is explained by their intercalation into the batches of the nucleic acids bases, which violates their functioning.
