摘要

Substituted 6-benzyl-4-oxopyrimidines having formula (I) are described, wherein: X is selected from the group consisting of O and S; R is selected from the group consisting of C1-4 alkyl and C5-6 cycloalkyl; R', R" and Z, equal or different among them mean H or C1-4 alkyl considering that, when X = O, R and R' cannot be both equal to H; their pharmaceutically acceptable salts and their soluble derivatives; one of their preparation processes and their use for the preparation of pharmaceutical compositions useful for the treatment of viral infections.
