Abstract
Rifazone-82, a new rifamycin derivative, is shown to preferentially inhibit the growth of virus-transformed chick cells in culture. Macromolecular synthesis and glucose uptake of transformed cells are also appreciably decreased in the presence of low concentrations of rifazone-82 where the normal cells appear unaffected. While rifazone-82 is shown to be a selective inhibitor of RNA-directed DNA polymerase in vitro, its action on the growth of transformed cells may involve some other mechanism.
Keywords: selective growth inhibition, virus transformation, chick fibroblasts
